Cold front and rain on the doorstep and then the weekend
This surface map, generated at 6:15 this morning, shows the approaching cold front on our doorstep:
An upper air disturbance sliding across the Ohio Valley along this front will bring showers and storms this morning and then the passage of the front itself will trigger more rain and a few thunderstorms early this afternoon. (Hopefully no more lightning damage will occur in and around Fredericksburg!) In fact the area of rain is not too far off to the northwest at the moment:
(The rainfall is the area of greens and yellows over northwestern Virginia; the blue shades over the I-95 corridor are a radar artifact.)
After the front slides southward of Fredericksburg this afternoon cooler and dryer Canadian air will replace our current soupy air. Today’s high temperature in the low 80s will be followed by another opportunity tonight to throw open the windows as the temperature drops to the 60-degree mark by morning, with more rural areas possibly seeing the upper 50s by dawn. Saturday and Sunday both look to be sunny with high temperatures in the low 80s and low humidity on this last full weekend of August.
The tropics continue to look quiet with a small disturbance currently off the coast of Louisiana in the Gulf of Mexico that the National Hurricane Center doesn’t expect to develop further as it moves westward. The eastern Atlantic contains a couple of tropical waves that have emerged off the coast of Africa but they don’t appear threatening at the moment. Still, with the peak of hurricane season approaching it will be prudent to keep an eye on things for a while.
Enjoy the weekend!!
