...MODERATE TO LOCALLY HEAVY RAIN TONIGHT...

...SHOWERS FRIDAY WITH STABLE CONDITIONS LOWERING VENTILATION...

.DISCUSSION...
A slow moving low pressure system and accompanying cold front will
keep a chance of rain at the burn site through Saturday morning. 
Tonight will see a period of moderate to locally heavy rain bring 
0.75 inches, with showers on Friday adding to that amount. Cool and 
stable conditions along with light winds will make for poor 
ventilation on Friday. A slight chance of showers lingers into 
Saturday morning, with drier conditions developing over the weekend. 
It will remain cool with some improvement in ventilation on Saturday.
