Another Stormy Day....

Another stormy day with Southern Plateau and Valley starting off with showers and thunderstorms.  This has prompted a urban and small streams advisory for Rhea County.  I expect heavy rain to be main threat again today with precipitable water values starting off in the 1.5 to 2.0 inch range.

Expect chances of showers and thunderstorms to continue today with highs in the lower 90s depending on cloud cover.  Remember greatest threat will be heavy rain and lightning.  I expect better chances for tomorrow and Friday as weak frontal boundary and low move toward the region.  I expect highs in the upper 80s to lower 90s depending on storms.  This weekend expect chances of afternoon storms with highs in the lower 90s.

Beginning With Rain....

Starting out with rain this morning across much of East Tennessee.  Most areas seeing light rain with a few pockets of heavier showers.

Radar at 7:20 AM EDT

I expect these showers and possibly a thunderstorm to plague the region most of today with moisture transport moving toward the region today.  Some of these showers and storms could be heavy at times with possibility of localized flooding.

Rain chances decrease for the weekend with mainly afternoon showers and thunderstorms as Atlantic ridge moves west.  Expect highs to return to the lower to mid 90s with lingering moisture will make for sticky conditions.

Update:
Chattanooga ended there 90 and above maximum temperature streak at 21 with yesterday's high of 79 degrees.

Rain To Start The Day....

Many parts of the region are seeing rain to start out the day with showers and possibly a few embedded thunderstorms moving through much of East Tennessee.

Radar at 7:34 AM EDT

It does look like showers and thunderstorms will be likely today with highs in the lower to mid 80s.  Again today many of these storms will produce heavy rains with precipitable water values around 1.5 to 1.8.  forecasts are indicating these values will be higher as we go into the afternoon.

So if you have outdoor plans today the weather could change rapidly.  Main threat today will be heavy rain and lightning.  Good chances of showers and thunderstorms will persist through the rest of the week.  It does look like this weekend high temperatures will return to the lower to mid 90s with afternoon thunderstorms possible.
