Finally found some time to sit and jot down a few thoughts. The storm is not behaving exactly as originally thought but it is pretty much running on schedule.
Overnight temperatures (Saturday-Sunday) were generally above freezing by a few degrees (unexpected) and the air was very dry (expected). The morning sounding at Dulles Airport showed the [...]
A powerful storm that came in from the Pacific should make weather headlines for much of the nation this weekend. A pretty good sign of the power and complexity of the storm can be found on the composite map of watches, warnings and advisories issued by the National Weather Service. The color coded [...]
With a high of 47F and a low of 32F, the average temperature at BWI-Marshall yesterday was 40F, and that ended a streak of 17 straight days with average temperatures below normal. Digging through the record books it looks to me like this was the longest stretch of below normal temperatures since late spring [...]
A quick update and slightly different skew to Tom’s February temperature figures below. National Weather Service records indicate that as of February 17, the official reporting stations in Baltimore over the past 137 years position this February in 9th place for the lowest average temperature with 24.9 degrees.
As Tom mentioned, the situation will be changing [...]
Only 14 times in the past 136 years, dating back to the start of official weather records for Baltimore in 1871, has the average temperature for the first half of February been below 30F. So the frigid February of 2007 is certainly one to take note of. In fact, with an average temperature [...]
The storm that dropped anywhere from a trace up to 6″ of snow and ice on central and eastern Maryland Tuesday and Wednesday is pushing farther north with blizzard warnings posted for much of interior New England. For much of the storm temperatures around the Baltimore area were well below freezing, prompting many to [...]
The stage seems to be set for a mix of just about every form of winter precipitation possible to show up in Maryland Tuesday. From snow to sleet to freezing rain to just rain. With our biggest snowstorms, cold high pressure is locked in over New England or eastern Canada, supplying the necessary [...]
Probably “messy” will turn out to be the best way to describe the developing storm. The various computer models are beginning to come around to the idea that warm air(+3 to +6 degrees celsius))will be drawn into the storm at the 850 mb level(several thousand feet above the surface)over the Baltimore area. This is expected [...]
Just a quick note about the snow forecast for Tuesday. The fine tuning continues. Computer models have been pushing the storm a bit further north with recent runs. This would move the likelyhood for the heaviest snow just to the north and northwest of Baltimore. If the northward migration continues in future model runs, the [...]
The Lake Effect Snow Machine is still working as the weekend begins. The NASA picture above shows some detail. Note that western portions of Lake Erie are now ice covered and that puts a damper on excessive snow generation downwind. The more open waters of Lake Ontario continue to provide the moisture and temperature contrast [...]
