Weekend on Tap for More Storm Chances, Early Next Week Still Looking Potentially Cooler

Setup for today looks similar to yesterday as we will, once more, have a favorable thermodynamic atmosphere in place for continued chances of thunderstorms during the afternoon and evening.  Low level moisture, steepening mid level lapse rates and moderate instability will all be in place for the Southeast.  I expect the convection to initiate over the mountains (as it has been for a while now) and travel down toward the Piedmont during the mid afternoon period but do not expect them to move quickly, as they will also move in similar fashion by either moving very slow or becoming stationary, causing local flooding from excess rainfall in the stronger storms.  Severe levels are also likely with any storm that pulses during peak heating so be careful.  We have had reports of streets flooded, scattered power outages, and trees down from the storms yesterday and that may be the case for us, some folks possibly getting hit again and those who missed out last time may get it this go around.  

Recent medium guidance is continuing its advertisement on a temporary cooler pattern to settle in for parts of the Southeast as a closed upper-level system is expected to trek eastward while crossing the Ontario region, causing upper-level troughing to take place near the East Coast.  This will aid in shooting down cooler air into areas such as the Carolinas where temperatures could be knocked back into the low-mid 80s with low humidity, which will make it feel very nice for the next few days during the early part of next week.  However, it's not set in stone so there is no telling whether or not modeling switches it up on us but will be glad to receive such a welcoming air mass.  It will only last a few days though as the high pressure that is to our north heads off the coast, causing the return flow to catch us and return our temperatures to the 90s once more. 

The tropics don't appear to be too interesting at the moment, though our disturbance is attempting to regain some of its strength as it finally begins its northward track through the Caribbean but still affected by the upper level winds that is shearing it some.  Its winds have since increased a bit but still doesn't show a definite sign of significant tropical development.  Here's the latest:

Be safe and as always, have a good day.
