Weather Blog: Since Fredericksburg resides "in the seam" between the Richmond VA and Washington DC media markets this blog is a look at the weather from a Fredericksburg-centric point of view.
A Fredericksburg weather pattern in molasses
Although it is mid-spring during which weather systems typically zoom across the nation, the current pattern seems to be stuck in a puddle of molasses with all the typical features barely creeping along.
The high pressure center parked off the New England coast for the past week or so is still there but is finally showing signs of oozing farther eastward into the Atlantic. It is being replaced by an equally snail-paced upper-level low pressure center cut off from the jet stream flow, which normally pushes such features along. (I was going to post a surface map showing today’s features but this next system looks so messy and complicated I decided not to.)
The low center has already pushed clouds northward over Fredericksburg and will follow that up with scattered showers during the day today and a steadier rainfall tonight. This rain event will last through at least Wednesday, dumping a fair amount of liquid on Fredericksburg and vicinity.
Here’s the potential three-day total rainfall map from the Weather Prediction Center:The medium purple shade that bisects Fredericksburg represents a three-day total of at least 1.75 inches of rain. Given recent dry conditions plus the extended period over which this rainfall will occur the NWS Sterling office has elected not to post any flood watches in our area.
Southwestern Virginia, however, is mostly covered in flood watches as that area is closer to the low-pressure center crossing the Carolinas and will receive appreciably more rainfall (as shown above).
As a result of the clouds and rain our high temperatures will be held down below normal levels again, which for the first week in May should reach the low 70s (F).
Today and tomorrow the ‘Burg will struggle to reach the mid-60s with a noticeable easterly breeze helping to make those windbreakers and rain jackets feel good. For those wanting to see more normal May temperatures the end of this week should provide some relief when temperatures climb back into the upper 70s by Thursday.
