Here's another link for the latest warnings: text of warnings

Flash Flood Watch in effect until 8 P.M.

A train of showers and thunderstorms will continue to produce moderate to heavy rain in counties along and just east of I-95 through the afternoon and early evening. Since we started out rather dry, the ground can only take so much. The National Weather Service has posted a Flash Flood Watch until 8 P.M. for these counties, including the Metro Richmond area and Tri-Cities. If you have to venture out, don't drive through water. Water covering the road is likely deeper than you think. Please use extreme caution...

The warmth continues to start the weekend...

Temperatures across the region made it into the mid and upper 80s today, one of the warmest days of the year so far. We'll get back into the 80s tomorrow to start the weekend, but cooler air is on the horizon. An upper low shifting east from the Ohio Valley will bring more clouds and some rain Saturday evening and Sunday. Temperatures will then come down a bit, averaging in the low 70s on Sunday and the 60s on Monday.

Cooler to start the new work week...

The clouds will persist as the upper low gradually moves off the coast. Any sun will likely be self-destructive, as a few showers pop up each afternoon Monday and probably Tuesday. Temperatures will probably stay mostly in the 60s, but as the upper low loses its influence, readings will be on the rise by mid-week.

And beyond...

No major events are likely, and temperatures in the longer range through next weekend look to be at or a bit above average. Another threat for rain may come by that weekend as well (April 26-27).

A soaking rain to start the weekend...

I hope you've enjoyed the brief taste of sunshine today, because rain is back in the forecast. A few scattered showers may pop up this evening, but the main rain is on schedule to arrive after 11 P.M. Low pressure developing along a cold front sliding in from the west will produce periods of heavy rain late tonight and tomorrow. Our model data suggests that we could see about 2 inches before the rain tapers off early Sunday morning.

A few thunderstorms possible as well...

I expect a few thunderstorms around the region as the front settles in. In the Metro Richmond area, the wind will be quick to turn to the north and northeast...and that will cool and stabilize the air a bit, so the threat for severe weather is well south. The Storm Prediction Center has the eastern Carolinas in the risk area tomorrow.

Slow clearing on Sunday...

Lots of lingering moisture is showing up on the model data for Sunday, so the clearing trend will be slow. That being said, skies could become partly sunny Sunday afternoon, with plenty of clouds hanging in along the coast. We'll dry out more significantly early next week, although temperatures will be slow to moderate back into the 60s.

The longer range...

We're still in for a pretty significant warm-up the end of next week...with a weekend front bringing quite a chill behind it early the following week (Mon 4/14-Tue 4/15).

R-Braves opening day...will there be rain?

Well baseball season is here, and the R-Braves open their final season at The Diamond Thursday at 4 P.M. There's rain in the forecast for Thursday evening and night, but I think the game will go on. Only light rain or drizzle will be around during the late afternoon, so while it won't be pretty, it won't be a washout. The heaviest rain probably won't occur until after 9 P.M. Right now, it appears from computer data that 0.25"-0.50" is possible by mid-morning Friday. That's certainly beneficial and there is likely more after that...

More rain late Friday into Saturday...

There should be a break in the rain on Friday, and that might allow the Braves to get game #2 in Friday evening, but another round of showers and thunderstorms is on the way Friday night into Saturday morning, with the highest risk time begin 9 P.M.-9 A.M. That means it will be wet for the Monument Avenue 10k Saturday morning. Rainfall tallies for this second event look more impressive, with an average of 0.75"-1.00" by midday Saturday. The clouds will probably linger Saturday afternoon, but I think most if not all of the rain should be gone.

Early next week...

Temperatures will be seasonable early next week, but an onshore flow may keep quite a few clouds around Monday and Tuesday. At this point, there's no reason to believe any significant rain chances, but we'll keep an eye on it.

In the longer term...

Other things to watch in the long term...a very warm end to next week, especially Friday 4/11...a front arrives next weekend with some rain (Sat 4/12-Sun 4/13), followed by some chilly air (Mon 4/14-Wed 4/16). Stay tuned...
