Summary: A very weak cold front moved through this afternoon, generating nothing more than some cloudiness. Skies will clear out tonight and early Thursday as the front drifts to our south and a weak surface high pressure system builds back into the region. The airmass behind the front is not much different than the one it is replacing so that, even though temperatures will be a few degrees cooler and the air will be drier (dewpoints in the 40s instead of 50s), it will still be warmer than average for this time of year with temperatures averaging in the low 70s.
The front will drift north and back over us on Friday in an attempt to move back through to our north. The front will make for an overcast day on Friday and will likely generate a few showers as well, although rainfall amounts should be relatively light.
A few days ago it looked like the the warm front would push through our region and usher in sunny, warm and even humid weather for the weekend. Unfortunately, it is starting to look like the front may stall over us on Saturday, then finally start to pull north on Sunday, but leaving us close enough to the front to maintain a low overcast with drizzle and a few sprinkles both days. However, any significant showers or rain are unlikely.
A stronger cold front, at the leading edge of a more amplified trough in the jet stream will bring a more significant rainfall here on Monday. The front then looks likely stall over us while a surface low pressure system develops along the front to our south and then moves north along the front and over us with additional rainfall on Tuesday. Ahhhh, this nice autumn weather couldn’t last forever.
