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 weekend of weather change on the way
The best phrase to describe this weekend’s weather? How about “The arrival of autumn?” After a strong cold front clears through the region Saturday evening the taste of fall will definitely be in the air (pun intended). But, as usual for such a transition, we need to be prepared for some storminess.
Today (Friday) will very likely be the last day of 2012 that Fredericksburg will see the 90 degree (F) mark. The sunny skies and still-humid air will combine to bring about a hot and sticky Friday as the cold front to our west gathers strength. Saturday this front plows into our region on its way southward and eastward. To give the reader an idea of how strong this front really is, it will be the first cold front since May to push completely off the Gulf Coast and down across the Florida peninsula.
That strength thus plowing into our current hot and moist airmass will lead to a stormy Saturday. Thus the Storm Prediction Center has issued a convective outlook for tomorrow that holds the promise of strong to severe storms for the ‘Burg.
The hatched area represents a 10% probability of severe weather within 25 miles of any given point within that area. That, plus the 30% red shading that incorporates the ‘Burg, is sufficient for a general warning to watch out for rough weather tomorrow afternoon and evening. Stay tuned to the media for real-time updates after lunch tomorrow.
Then, the good news…the airmass behind this cold front is truly Canadian in origin and will usher in cooler and much drier air for Sunday and most of next week. The forecast temperatures are for highs in the upper 70′s to low 80′s and the lows in the upper 50′s to low 60′s. It is finally going to feel like meteorological autumn, which began on September 1st. Enjoy the transition!
