Unseasonably warm today, with rain Friday morning

Posted: Updated:
CHATTANOOGA, TN (WRCB) - Good Thursday.  The next few days will see quite a few changes in our weather. 
High pressure to our east will pump in a stream of warm air from the south.  The high this afternoon will reach 88 once again under mostly sunny skies. Tonight clouds will begin to build ahead of a cold front.  Overnight we will see scattered showers developing with the low dropping to 67.

Friday morning, as the front pushes through, I expect periods of heavy rain and some thunderstorms widespread between the hours of 6am and 10am.  The biggest threats for the morning commute will be slick roads, heavy rain, and some isolated areas of flash flooding where downpours occur.  We will not see any tornadoes with these storms, although we may have some gusty winds that could produce damage on the plateau and westward.


Friday afternoon, cooler air will start to filter in.  The high will reach 79.  I do think we will continue to see what I call "remnant" showers popping up here and there through the afternoon and evening hours.  That means we may see a few showers for the Friday night football games as temps drop through the 60s during the evening.  Rainfall amounts through the day will range from 1" to 2" widespread with locally higher amounts.


Saturday, the cool air really settles in.  Saturday morning we will start with a low of 48.  The air will be almost bone dry.  Dew points will drop from the 60s into the 30s.  Saturday afternoon will be sunny, and the high will only climb to about 63!


The coldest air will move in Saturday night.  I expect clear skies, and the low in Chattanooga dropping to 42.  In the mountains it will drop into the upper 30s!  As Sunday progresses, southerly winds will kick back in allowing us to warm nicely into the low 70s.


We could see more showers to start next week.
