SUMMARY OF CLIMATOLOGICAL DATA 


JANUARY 2009


... COLDER AND DRIER FOR MOST STATIONS THROUGOUT THE MID-ATLANTIC ...

After a fairly mild start to the month, a lot of cold air settled over the Mid-Atlantic States with several stations reporting low temps below 0F. There wasn't a lot of moisture to work with as strongest storms stayed well to the north and significant weather over the Gulf coastal states was unremarkable. Still, Alberta-clipper type storms moved across the area frequently which helped to keep the cold air in place over the Mid-Atlantic. A couple of these clippers moved across North Carolina providing the Tar Heel State with two winter events producing several inches of mostly localized snow. Bob Woodson in Raleigh (RAL) received 6" of snow on inauguration day!
  • THE NOAA RESOURCES PAGE    The National Oceanic and Atmospheric Administration (NOAA) has many exciting informative resources available for the public to view and learn about the oceans and atmosphere. CoCoRaHS in partnership with NOAA will continue to strive to bring you the latest products and information as it becomes available. To learn more about NOAA Resources listed on the CoCoRaHS Web site click on the NOAA logo on the left side of our home page: www.cocorahs.org or click here: "NOAA Resources" at http://www.cocorahs.org/Content.aspx?page=noaa.


  • SNOWFALL MEASUREMENT REMINDER from CoCoRAHS    Also from the CoCoRAHS' website comes this: " Snowfall Depth . . . Report to the tenth of an inch! New snowfall depth is measured to the "tenth" of an inch, not "hundredth" as rainfall is. So when reporting snowfall depth remember only one decimal place. If you are using a regular ruler here is a review of the conversions to the nearest tenth-inch increments: 1/16 = 0.1, 1/8 = 0.1, 3/16 = 0.2, 1/4 = 0.3, 5/16 = 0.3, 3/8 = 0.4, 7/16 = 0.4, 1/2 = 0.5, 9/16 = 0.6, 5/8 = 0.6, 11/16 = 0.7, 3/4 = 0.8, 13/16 = 0.8, 7/8 = 0.9, 15/16 = 0.9 ... "


  • FREEZING RAIN    Here's another reminder from CoCoRAHS: "Freezing rain is rain that falls in liquid form but freezes on contact with the ground and objects above the ground. Do NOT report freezing rain as 'Snow. If you have an inch of freezing rain accumulate, you melt and measure the moisture that has accumulated inside your gauge and you report that as your daily precipitation amount. You report ZERO for your new snow amount (assuming it all fell as rain, and no sleet or snow accumulated). You DO report the total depth of freezing rain that has accumulated on the ground and enter that in the "Total Snow on Ground" column. Again, make a note in your comments section of your report so that we know its freezing rain. A very useful measure of freezing rain is the "radial thickness" of ice on wires, branches, etc. If you can, measure the ice thickness on a wire or branch and report in your "Comments" the average radius of the ice (not the diameter)."


  • DROUGHT MONITOR    http://www.drought.unl.edu/dm/monitor.html    More information on drought can be found at NOAA's Drought Information Center http://www.drought.noaa.gov/

    Virginia:

    Arlington - From NWS WBC come these notes: " AT WASHINGTON REAGAN NATIONAL...THE JANUARY 2009 AVERAGE MONTHLY TEMPERATURE WAS WELL BELOW NORMAL...TIED FOR 32ND COLDEST ON RECORD. IT WAS THE COLDEST JANUARY SINCE 2004. 20 OUT OF 31 DAYS THIS JANUARY AVERAGED BELOW NORMAL. THE HIGHEST TEMPERATURE FOR THE MONTH OF JANUARY WAS 51F...ON THE 5TH AND 23RD. THIS WAS THE LOWEST MAX TEMPERATURE FOR THE MONTH SINCE JANUARY 1977...WHEN 49F WAS RECORDED. PRECIPITATION FOR JANUARY 2009 WAS BELOW NORMAL. THE 19TH WAS THE ONLY DAY WITH MEASURABLE SNOWFALL FOR THE MONTH. THE TOTAL OF 1.9 INCHES OF SNOW WAS WELL BELOW NORMAL BUT SLIGHTLY MORE COMPARED TO THE 1.3 INCHES RECORDED LAST JANUARY 2008. OVERALL THIS IS THE 4TH JANUARY IN A ROW WITH BELOW NORMAL SNOWFALL. " [ - - ] 

    Bridgewater - " The temperature was 1.8 degrees above normal while the precipitation was .27 inches below normal. The first measurable snow of the season occurred on the 27th. The zero reading on the 16th was the first zero reading in 13 years. An unusual snow occurred on February 2. It snowed with the temperature at 40 degrees. The next morning, the sun came out, and shone on all the snow covered trees and bushes presenting a beautiful winter scene. By the way, the ground hog saw his shadow so be prepared! " - [ + - ] - notes from Clayton

    Centreville - " As with the latest trends in the economy, January too was depressing. Having had periods of consistently low temperatures during the third and forth weeks of the month, January couldn't muster any more than a measly gain of 2.4 inches of snow. This is also the seasonal total, so with a little luck a moderate recovery could still be in the cards. Waking in the morning of the 23rd began with temperatures typically in the 20's, but by noon changes were afoot that would cause the warmest day of the month to be tallied. By mid-afternoon we had our high in the books at 58 with the next warmest days being 50 recorded on the 5th and 24th. Our average monthly temperature of 30.1 worked out to be 1.4 below the normal 31.5 average for January. The lowest temperature for January was 2 on the 17th, with all but one other day during the month with recordings of freezing or below. That one day happened to be 36 on the 5th. It looks here that the 5th was a real scorcher! True to form, the low average for January was higher than the predicted 21.8 by +0.7. No doubt, this has something to do with why my snow blower continues to frown and still remains covered in the shed. Precipitation let all the winter tricks out of the bag in January. Rain wise, we picked up 2.95 inches that includes 0.25" form snow on the 27th. The monthly total was 0.57" short, or 84% of the 3.52" normal. At least we are better off from a year ago when January produced less than half of what was usually expected. The greatest 24 hour rain event occurred on January 6th and 7th when a total of 1.51" was recorded. This amounted to 51% of our monthly accumulation. The only snow day was really a mix of all the wintry junk rolled into one event on the 27th coupled with below freezing temperatures days before and a day to thaw and then refreeze afterwards. Yes, we began with snowfall of varying intensities throughout the day on the 27th for 2.4" before changing over to rain, freezing rain, and sleet by late afternoon. The freezing rain with a touch of light fog continued into the day on the 28th, gradually ending around noon and temperatures increasing to 42 throughout the afternoon. Yes, refreezing did occur... So there you have it from the winter wonderland of sunny Centreville. " - [ - - ] - notes from Paul

    Chantilly - Russ reports: " After a mild December and beginning of January, we ended up with our coldest January average in 5 years. Six days did not make it above 32 and we saw many ponds and lakes freeze over. The average monthly temperature was only 1.5 below normal, but in comparison to recent winters it seemed unusually cold. Total precipitation for the month was 2.79", which was 0.26" below normal. The maximum calendar day rainfall of 1.15" fell on the 7th. A trace of snow fell on 15th and 19th. Our worst winter storm of the season brought a meager 2.0" of snow on the 27th, which then turned to freezing rain and sleet and continued on the 28th. School children rejoiced, as the ice (.25" on the 27th and .125" on the 28th) was enough to close schools for the first time this winter. As noted by several, this is the 9th consecutive January with below normal snowfall. Sorry snow lovers and plow drivers. *Please note, anemometer is currently partially obstructed from the Southeast " - [ - - ]

    Dulles - from NWS Sterling (KLWX) come these notes: " AT DULLES...THE JANUARY 2009 AVERAGE MONTHLY TEMPERATURE WAS BELOW NORMAL...THE 18TH COLDEST ON RECORD...AND THE COLDEST JANUARY SINCE 2004. 18 OUT OF 31 DAYS THIS JANUARY AVERAGED BELOW NORMAL. THE MINIMUM TEMPERATURE OF ZERO DEG F ON THE 17TH WAS THE LOWEST MIN TEMPERATURE RECORDED AT DULLES SINCE FEB 6 1996 WHEN IT WAS -9 DEGF. JANUARY 2009 MONTHLY PRECIPITATION WAS SLIGHTLY BELOW NORMAL AS WELL WITH NEARLY HALF OF THE MONTHLY PRECIPITATION FALLING ON THE 7TH. THE 19TH WAS THE ONLY DAY WITH MEASURABLE SNOWFALL FOR THE MONTH. THE SNOW TOTAL OF 2.0 INCHES WAS OVER 6 INCHES BELOW NORMAL. OVERALL THIS IS THE 9TH JANUARY IN A ROW WITH BELOW NORMAL SNOWFALL. " - [ - - ]

    Front Royal - Mike sends these additional summary notes: " Everything was below normal in January 2009. The average high temperature of 38.4 was about 5 degrees below normal. Average low was 21.1 which is about a degree below normal. There was a 61 degree temp difference between the highest and the lowest temp recorded this month. Zero was the lowest. Out of the 2.05" of total precipitation recorded only 2.4" of snow fell, which is about 4" below normal. Overall it was a disappointing weather month. Yea, the cold was nice. In a way though the old saying of "it was too cold to snow" was true. Days 1-10: The 36 high on the first would be the coolest daytime high until the 10th. In between mild winter weather was the experience here in the Shenandoah Valley of VA. The first precipitation of the month fell on the 6th from a low pressure area and associated front that moved far to the northeast of the area. The .72" that fell on the 6th was duplicated again on the 7th, but no frozen precipitation was found here. The next little event on the 10th consisted of spotty ice in the greater Washington DC area, but only liquid precipitation could be found at this station. Days 11-13 These three days would be the last time a 40 reading would be seen until the 22nd. Sunny skies on the 11th and 12 and an early evening cold frontal passage on the 13th was all the excitement we had before some of the coldest weather in several years affected the area. Days 14-22 Out of these 9 days temps remained below freezing for 6 of them. The coldest of these days was the 16th. The high temperature of 18 helped us achieve the 0 reading the following morning which would be the lowest temperature of the month. A warm-up if you will occurred on the 18th when we hit 39, but was short lived as another artic front brought temps right back down. A whopping .3" fell from snow showers from a short wave that traversed the area on the afternoon of the 19th. Snow was found in far southeast VA and North Carolina on the 20th, but sunshine was the rule here as that low pressure was too far south to do any good here. The 21st and 22nd were nice days as high pressure was centered to the south and temps moderated slightly. Days 23 and 24 The 61 high on the 23rd was actually quite a welcome break from the cold weather. Clouds increased late on the 23rd and the 51 high on the 24th was set at midnight. After the frontal passage temps fell the remainder of the day and fell into the 20s by noon and stayed there. A dusting of snow occurred from a few snow showers as well. Days 25-28 Temps made it to 33 on the 25th, but remained below the 26th and 27th. Low pressure to the south brought us 1.9" of snow on the 27th. Snowfall began here around 4:30am and was moderate for a short time before that batch ended just before noon. Another area of moisture which started as a brief period of snow 12hrs from the 1st quickly turned to all sleet and then freezing rain by midnight. Moderating temperatures turned what precipitation remained to all rain by morning. However, minor traffic problems resulted from ice accumulation here and in the DC area and most schools closed. 29-31 The month closed on a quiet note with near normal temperatures and no precipitation.

The 1.95 inches of rain for January was a -1.41 inch departure when compared to the Ashland, VA average. The maximum rainfall recorded in a day was only 0.61 inches on the 27th on a day of sleet, snow, glaze but mostly sleet. Measurable precipitation occurred on only eight days and it is noteworthy that there wasn't any measurable precipitation from and including the 12th to the 26th a fifteen day period. The only frozen precipitation was 0.3 inches of mostly sleet for the month all recorded on the 27th which was a -5.5 inch departure compared to Ashland, Virginia records. January was cloudier than average. The maximum temperature for January was only 62F on the 23rd and the lowest minimum was 4F recorded here on the 17th. This was the lowest minimum temperature of the winter recorded at this station and according to Channel 12 the coldest since January of 2004. The lowest dew point temperature on the 16th at 1659 was -12.8F quite low for the Glen Allen area. The maximum wind gust of 37 mph occurred on the 7th at 1806.

January gave us a total of 3.01 inches of precipitation and was only 0.17 inch below normal for precipitation, but we had a wintry mix fall during two periods in the month. On the 7th and 8th we had 2.05 inches of precip and a little bit of freezing rain mixed in. The bigger event occurred on the 27th and 28th when we had 2 inches of snow and sleet followed by a inch of freezing rain causing many hazardous walking and driving conditions. The total precipitation during this event was 0.75 inches. As for the temperatures, we had a very cold month with the average coming in 4.7 degrees below normal.

    Portsmouth - " January was a much colder, drier month when compared to January's from 1977 to 2008. The infiltrating drier air helped shunt moisture from two expected systems further south, bypassing the locale and giving nothing more than flurries. The 1.89" of rain produced a January that was 1.76" BELOW normal rainfall. The month's average temp was 2.7 BELOW normal Frost occurred on the 1st, 2nd, 3rd ; 4th; 10th, 12th, 15th, 16th, 17th, 21st, 22nd, 23rd, 29th, 30th, 31st. COLD FRONTAL PASSAGES were recorded on the 2nd, 5th, 7th, 8th, 13th, 14th, 15th, 20th, 24th, 28th, 30th while WARM FRONTAL PASSAGES were noted on the 7th & 28th.
