Rounds of rain through Wednesday AM could lead to post-Christmas travel trouble

Tuesday will be rainy at times.

ROANOKE, Va.A Flood Watch is in effect for the southern Blue Ridge until 10 a.m. Wednesday.

As the afternoon continues building rain is causing some flooding. The risk is somewhat low, but a Flood Watch is in effect through Wednesday morning in the NRV with a Flood Advisory for Tuesday afternoon in Grayson and Wythe Counties.

The rainfall on Tuesday built up in the NRV early in the day causing some flooding already.

That flooding prompted a Flood Advisory for areas experiencing high water. Be extra careful as you drive through the afternoon.

Galax and Wytheville are both in the Flood Advisory

Heavy rain in neighboring counties prompted a Flood Watch since the environment is set up better for flooding. Be careful through the night into Wednesday morning of any high water.

Temperatures stay steady Tuesday, but a little breeze from the west Wednesday will push us well into the 50s and lower 60s.

High temperatures rise into the 50s and 60s Wednesday after a cool Tuesday.

As our area of low pressure finally gets shoved east Friday, it will try to produce scattered rain showers and mountain snow (mostly above 3,000 feet).

Scattered rain and mountain snow showers will be possible late Friday.

We’ll then turn windy Saturday with a dry and seasonable New Year’s Eve.

Come New Year’s Day, we’ll track a separate storm system that will try to mesh with our colder air in place.

We'll turn windy Saturday, seasonable Sunday and potentially wet/wintry New Year's Day. Stay tuned!

Could this spell snow? It’s too soon to know for sure, as there are multiple moving pieces a week out.

At the moment, the odds are low. That said, a pattern like this will need to be watched in the coming weeks and months.
