Original Post:
The ongoing blizzard in the Texas panhandle is threatening to break some all-time Texas snowfall records. These are the current snowfall records at Amarillo, from the National Weather Service:

Max for 24 hours: 20.6 inches on March 25-26, 1934
Max for a single storm: 20.6 inches on March 25-26, 1934
Max for one month: 28.7 inches in February 1903
Max measured snow depth: 17.0 inches on February 26, 1903
Max for a season: 50.9 inches in 1918-19

The NWS at Amarillo reports:
GOING FORECAST STILL ON TRACK. THE NWS OFFICE NOW HAS OVER 13 INCHES
ON THE GROUND WITH 3-4 FOOT DRIFTS AND A MAX GUST TO 58 MPH. THE SE
TX PANHANDLE HAS BEEN SLOW TO FILL IN WITH SNOW AFTER THE
THUNDERSTORMS THAT DROPPED HEAVY RAIN LAST NIGHT AND THESE AREAS
MIGHT END UP WITH AMOUNTS CLOSER TO THE 8 INCH SIDE THAN THE 14 INCH
SIDE OF THEIR RANGE. AT THE END OF THE DAY...THE HEAVIEST TOTALS
WILL ALMOST CERTAINLY BE ALONG A PALO DURO CANYON TO AMARILLO TO
STINNETT TO PERRYTON LINE.

SOME RECORDS SEEM TO BE IN A PRECARIOUS POSITION TODAY. THE FIRST IS
AN ALL-TIME 24 HOUR SNOWFALL RECORD AT AMARILLO OF 20.6 INCHES FROM
MARCH 25-26 1934. WE WILL LIKELY GET VERY CLOSE OR SURPASS THIS
NUMBER BY THIS AFTERNOON.

THE OTHER IS THE ALL-TIME STATE OF TEXAS 24 HOUR SNOWFALL RECORD OF
25 INCHES IN FOLLETT SET MARCH 28 2009. SOMEWHERE IN THE
PERRYTON/STINNETT/BORGER/AMARILLO AREA COULD APPROACH THIS VALUE BY
THIS AFTERNOON.

Record Low Mid-Atmospheric Pressure Predicted for Midwest Blizzard


The maximum intensity for the developing Midwest blizzard is nearly 2 days away, but a major forecast model is predicting mid-atmospheric pressures at least as low as any observed during February in the region since systematic upper-air observations began in 1948. Based on data from this morning, the NOAA/NCEP GFS model is predicting super-low pressures by Tuesday morning near the middle of the atmosphere above the storm. The map above shows the predicted height (meters) of the level at which the pressure is 500 mb, or roughly half the value at the surface. The small circle near the Missouri-Arkansas border is labeled 528, or 5280 meters (approximately 3 miles). The values inside the circle would be even lower. According to historical data from NOAA's Earth System Research Laboratory, the 500 mb height has never been as low as 5280 meters in that region since 1948. Here is a list of the top 10 lowest observations in February at latitude 35 N, longitude 90 W:
Date       Meters
1991,2,15, 5287
1964,2,19, 5314
1978,2,21, 5318
1984,2,28, 5323
1965,2,25, 5334
1970,2, 3, 5345
1971,2, 9, 5357
2010,2,15, 5357
1958,2, 2, 5361
1984,2, 5, 5361 

Looked at another way, the composite forecast from an ensemble of GFS forecast runs made from last night's data indicates that the 500 mb height departure from the long-term average will be as much as 5 standard deviations by Monday night (chart to the right, click to enlarge). For a purely randomly distributed event, a negative departure from average of 4.5 standard deviations would occur only 3 times in a million.

Next Storm Threatens Wichita All-Time Monthly Snow Record [Update: Record Broken]


February 26, 9 AM CST Update: The Wichita daily record snowfall of 4.8" yesterday, plus 2" so far today, brings the monthly total to 21", which breaks the record.

February 25, 8 PM CST Update: The heaviest snow appears to be passing south of Wichita. The National Weather Service reports just 1.9" so far today.

4 PM CST Update: The latest National Weather Service updated forecast calls for over 14" of snow at Wichita. This could exceed the old monthly record by an incredible 8":



Original Post:
It's still getting itself organized over the Rockies, but the next Midwest storm is threatening to bring heavy snow to Kansas for the second time within a week. The current forecast is calling for 6-12" of new snow for Wichita. If this verifies even slightly above the low end of the range, it could push the current monthly total of 14.2" above the all-time monthly record of 20.5" set exactly 100 years ago.

SnowNoGettin': Washington on Track for Record Lowest 3-Year Total Snowfall, Largest 3-Year Decrease



As the massive snowfalls of the 2009-1010 season fade into the rear-view mirror, Washington DC is close to ending meteorological winter with a near-record low 3-year snow total. With the latest nor'easter bombing out well offshore, there is no Presidents' Day snowfall this year, and model indications are that there will be little, if any, snow in the next 10 days. That would end meteorological winter with a puny 1.5", the lowest since the 0.1" in November 1997 through February 1998. For the past 3 years, the winter total of 13.4" is likely to be the second lowest on record, ahead of the 14.1" in the 3-year interval ending in 2008-09. This means that two of the three lowest 3-year totals will be the periods immediately preceding and following the record season of 2009-2010.

For the entire season (including all months), assuming no more snow in February, the highly erratic month of March would have to contribute nearly 5" for the 3-year seasonal total to exceed the current record low for the period ending in 1998-99.

Comparing consecutive 3-year totals, the current amount of 13.6" is a massive 54.6" less than the 3-year total ending last year, which included the record high season. This is over 13" more than the 3-year decrease observed in 1901-02, the current record decrease.

Image (click to enlarge): Top 10 snowfall totals for southern New England, from National Weather Service

February 10 Update: The Providence total has been corrected to 16.6", making this the 9th biggest snowstorm.

Original Post:
As the snow has wound down over New England, the National Weather Service is reporting top 10 storm snowfall totals at its major climate reporting stations. The preliminary total of 31.9" at Portland was an all-time record, but official climate records at Portland extend back only to 1941.
