A Rainy Forecast Is A Good Thing

Although rain can be disruptive to our day-to-day lives, we desperately need some in our area. You can see on the graph below that we are 1.7" below normal for the year.






We aren't the only ones dealing with dry conditions. You can see on the map below that most of the Southeast is 2 to 8" below normal for rainfall this year.






Not surprisingly, numerous rivers and streams are now running below normal. The ones to the west are near normal from the heavy rains we saw earlier this month.






Right now, moderate drought extends across central and southern Virginia.






Luckily, we will see an active weather pattern over the next several days. In fact, two back-to-back storm systems could bring 1 to 2" of rain from Wednesday into Thursday. This is great news!

Snow Possible Early Monday

Weather Update - Last Call

It is 6:30 Sunday morning and it is currently raining and sleeting in Richmond with temperatures at 35 degrees. Here is the timeline for the rest of today:

8 to 11 AM
Wintry mix of rain, sleet and wet snow. This will be the best chance to see big wet snow flakes. Temperatures will hover in the mid 30s and lower 30s across the entire area. The magic number is 35 degrees, which is usually the rain/snow line in these types of situations.

11 AM to 2 PM
Precip will quickly taper across the entire area. Temperatures will warm into the low 40s, which will melt most if not all of the snow. I’m expecting 1” or less across most of our area (click here for my latest accumulation forecast), with all snow sticking only on grassy surfaces and other things detached from the ground. Roads will remain wet but drivable.
