We have a sun/cloud mix and temperatures reaching the mid/upper 70s today. http://aviationweather.gov/adds/satellite/displaySat.php?region=DTW&isingle=single&itype=vis Slight risk for severe weather will threaten our easternmost forecast area this afternoon. Max daytime heating & sufficient instability will bring breezy conditions and possibly even a tornado to the Eastern Panhandle, DC/VA/MD corridor. Otherwise, a few mid level clouds & a stray shower or two will graze our area overnight & into Thursday as that Great Lakes low pressure continues to toss plenty of moisture over the Mid Atlantic states. But the reign of the Great Lakes low will soon come to an end as a strong Canadian front sweeps across the eastern US Friday. With it, a well-defined line of showers & much cooler temperatures will cross our area Friday & Friday night. The bottom will really fall out of our temperatures this weekend! Highs will only reach the upper 50s. Nights will see temps in the low 40s/upper 30s. Ideal fog set up will allow dense morning fog this weekend. But lingering moisture will keep threat for a few showers, especially in the mountains into Saturday. Things really dry out Saturday night, Sunday and into next week! More later...
