Cold and slow start to a Wednesday morning

This morning’s low temperature of 25 degrees recorded by the UMW weather station combined with northwesterly breezes gusting to over 20 mph brought about a slow start to the day. (That’s my excuse for not posting this earlier!) To provide a measure of how unusually cool this airmass is, the normal high temperature for today is 61 degrees. That seems pretty toasty compared to the forecast high of 44!

This is an early season example of an Arctic airmass, which is much dryer and colder than typical air swooping south out of Canada. The low dewpoints are tough on both skin surfaces and vegetation.  In fact there is currently a Special Weather Statement from NWS Sterling in place detailing the potential fire danger from the winds and the dry air so please be careful outside today.

Speaking of dry the specter of drought is once again creeping into Virginia. Here is the latest graphic from the U.S. Drought Monitor website:

The yellow shaded regions are areas experiencing “abnormally dry” conditions, the first stage of drought.  The dry autumn we’ve had isn’t helping the situation and may be setting a pattern for the winter months as well. (More to come on that later.)

The good news regarding temperatures is that Fredericksburg and vicinity will rebound quickly starting as early as tomorrow, with the forecast high climbing back into the mid-50s.

By Friday we’ll be back to more normal thermometer readings that will broach the 60-degree mark.  The approach of another cold front will bring a chance of rain by Sunday afternoon into Monday.  Behind that front, another very cold airmass is on the way so don’t put those coats too far back into the closet!
