Sunshine for the beginning of May
Surprisingly enough the sun is shining in Fredericksburg!! After a low of 49 degrees this morning at the UMW weather station the low clouds have been shunted southward. We won’t see any major changes to the weather for the next several days due to the current “blocking pattern” in which the normal west-to-east weather flow across the nation is bottled up like an I-95 traffic jam. Thus the high-pressure system off the northeastern U.S. coast is stuck in place and won’t move much until sometime next week.
The good news is that the cold air damming misery of low clouds and drizzle from the northeasterly winds around that high pressure system will be countered by sinking air – known as subsidence – as the high strengthens and grows in our direction. This subsidence effect will erode any early morning cloudiness over the next few days so that Fredericksburg will benefit from mostly sunny skies and light winds through the weekend. Temperatures will average near normal as well, with highs near or just above 70 degrees and morning lows in the mid-40s.
We won’t see much precipitation until next week but central and southern portions of the country will be pretty wet over the next several days as shown in this Weather Prediction Center graphic:
That’s good news for some of the drought-prone areas out west even though the current cold and wet conditions are interfering with spring planting. Eventually some of that moisture will work its way into the Mid-Atlantic so our sunny weather won’t last forever. Enjoy!
