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.
One final cool morning before a pattern change
This morning’s cool temperatures (upper 50s) are the last remnants of our somewhat abnormal “Augtober” weather. This afternoon Fredericksburg thermometers will reach the 90 degree mark ahead of a frontal passage that won’t cool things off much. There is not much chance of rain with this front given the sinking air in the wake of Hurricane Cristobal’s passage well east of the coastline. (Sinking air suppresses convection.)
Thursday and Friday will both be sunny with maximum temperatures in the mid-80s plus a bit higher humidity. That’s just about average for late August…but then comes the pattern change. Check out this Climate Prediction Center temperature forecast graphic for the first week of next month:
Our long term pattern of upper air troughs over the East Coast has kept the door open for cool Canadian air to overspread our region. This weekend that pattern will shift to one that looks a lot like July and August. A Bermuda High will set up over the western Atlantic and pump warm moist air from the Gulf of Mexico northward into the ‘Burg.
Thus the first half of September temperatures look to be above (vice below) average with hot and sticky conditions prevailing. That will certainly have implications for how to dress kids for school. It also may open the door to more tropical development than we’ve seen so far this hurricane season. Stay tuned for further developments!!
