SUMMARY OF CLIMATOLOGICAL DATA 


JANUARY 2011


...CONTINUED BELOW NORMAL TEMPERATURES & RAINFALL...

December's increasingly cold weather persisted into the first month of 2011. Temperature averages and rainfall were below normal across the region. While snowfall totals did not reach the high amounts experienced by many in December 2010, snowfall did increase for the mountains of the three-state area. To the surprise of our region's southern inhabitants, snowfall events produced several inches of snow in areas which rarely see wintry weather. 6 inches of snow fell at Cape Hatteras on the 22nd as low pressure south-southeast of the barrier islands threw signifcant moisture into cold air covering coast.

The thunder sleet and snow, which began the intense snow event on the 26th just prior to evening rush hour, turned 30-minute commutes into 7-hour commutes. It was a winter storm few will forget any time soon. *Please note, anemometer is currently partially obstructed from the Southeast " - [ - - ]

    Glen Allen - Lowell Koontz adds these notes: " January was colder than average as the monthly mean temperature was 34.8F, a -1.3F departure, and it was drier than average (when compared to Ashland, VA records). The first two days in January were the warmest two days of the month. There were 28 days where the minimum temperature dropped below freezing and two days that the maximum temperature stayed below freezing The 2.22 inches of precipitation for January was a -1.14 inch departure when compared to the Ashland, VA average, however, 2009 had less with only 1.95 inches. The maximum precipitation recorded in a day was 1.27 inches on January 26th and is the most ever recorded in a calendar day at the Glen Allen station for the month January. The month had 11 days with precipitation, which is also a new record for January. The mean temperature for Glen Allen was 34.8F which made January the coldest since 2009. The maximum temperature for January was 60F on January 1st but was the lowest maximum monthly temperature ever recorded at this station for January. January also had the lowest average maximum temperature, which was caused in part by the cloudy month. Glen Allen also had the lowest average temperature range ever recorded for the month of January. The average temperature range at the Airport was the lowest since 2004. The lowest minimum was 13F, which was recorded here on the 23rd. The lowest barometric pressure of the month was 29.37 inches and recorded on the 8th ; the highest was only 30.47 inches on January 4th. This was the first January that thunder was recorded at the Glen Allen station. The maximum wind gust for the month was only 26 mph that occurred on the 29th of the month from the SSW at 1503 but the windiest day occurred on January 15 with a 104.5-mile wind run. This month was the cloudiest of the past three years and in part explains the lowest average temperature range for January at the Glen Allen station. The Richmond International Airport set one record for the month. The 1.38 inches of precipitation that fell on the 26th was the most precipitation ever recorded for the date. The previous record was 1.28 inches in 1966. January had the 28th lowest mean temperature of the last 114 years. January was the 40th driest of the past 114 years. Only 2 inches of snow fell at the Richmond International Airport this past January making it the 56th least amount of snowfall in the last 114 years. " - [ - - ] 

    Herndon - Randy adds: " January was well below normal for temperature and below normal for precipitation. This trend has existed all winter. The temperatures ranged between a high of 58 and a low of 8. The average highs/lows were 4.6 and 3.3 degrees below normal, respectively. 26 of 28 days had the low temperatures at or below freezing, the other two days the low was 33. On the precipitation side, the month was 0.91" below normal with only 2.17" measured. Most of this came on 26 Jan when we received 1.51". This day provided a little bit of everything with sleet, freezing rain and drizzle, thunder snow showers and snow. This storm caused major traffic problems and massive power outages. In addition to this storm system, we had four other periods of sleet, freezing rain or freezing drizzle, which caused lots of traffic problems and school closures. Thus far it has been a very icy winter. We have now had 13.4" of snow for the season. " - [ - - ]

    Portsmouth - " January's average temperature (35.6) was 4.6 BELOW NORMAL. Rainfall was BELOW NORMAL by 0.47" or 87% of normal relative to normal Decembers for the period from 1976 to 2009. Only a trace of snow on the ground on two days coming after the snowiest December on record.

Dec/Jan well below normal- Precipitation also well below normal- Still looking for any signs of Global Warming. Just about now we could use a little warmth. Temperatures continue to remain at or below both the 30yr data or the 125yr data. " - [ - - ]

    Raleigh - Bob sends these notes: " The average daily temperature for January was 2.4 degrees below normal; however January was still warmer than December's very cold readings (what happened to global warming). As expected wih a LaNina pattern, precipitation was well below normal with only 1.38" measured. Light snow, sleet, and freezing rain occurred on the 10th and 11th. No big deal! No severe weather was observed during January. " - [ - - ]

    North Whiteville - Christopher adds these comments: " Overall January was very cold and breezy. There were 5 consecutive days with high temperatures below 40 degrees. The highlight of the month came on January 10. What was originally predicted to be only 1-2 inches of snow, with a changeover to rain, turned out to be a significant snow and ice storm, with 5.2 inches of snow and 0.25 inch of ice on top of that. That snow remained on the ground for 6 days, and most area schools were closed Monday through Thursday of that week. " - [ - - ]
