Weather Summary:

Isolated pop-up showers or thundershowers are expected through the evening, but mainly across the mountains south and east of the Tri-Cities. There's just a slight chance of rain around BMS for the Pitt Lite 125. 

Periods of rain are likely Sunday with thunderstorms certainly possible in the afternoon. A few storms may become strong to severe in spots.  A slight risk for severe weather has been issued for areas west of the Tri-Cities.  Some storms could contain heavy downpours, gusty winds and even hail in spots.  Be on the alert to these conditions, especially if you plan on being outdoors at the race Sunday afternoon. 

Heavier showers will likely be situated over the North Carolina High Country, thanks to more lift along the mountainous terrain.  This has prompted a Flood Watch to be issued for Avery, Ashe, Watauga counties in North Carolina and Grayson County in southwest Virginia. 

We'll be watching this weather pattern very closely as it may have implications on the Sunday race.  Have the rain gear handy and a plan to get to a safe spot should storms impact the race during the afternoon.

Showers and a few thundershowers are likely Monday ahead of a strong cold front.  Given enough instability in the atmosphere, some storms may contain gusty winds, frequent lightning and heavy downpours.  As a cold front sweeps east of the Tri-Cities Monday night, the weather will be drying out Tuesday and Wednesday! Temperatures will actually fall to below average for the middle of the week. 

There's a slight chance of a few pop up showers during the middle of the week, but for now there's no widespread threat.  Expect temperatures to run in below average into the weekend as well.

Recap: Highs will be in the middle 60s to lower 70s Sunday and Monday, mainly in the 60s for the remainder of the week.  Lows in the 50s through Sunday night...40s Monday night...upper 30s to mid 40s through the remainder of the week.

Our average high is 69°, low 43°.
