Friday Flooding Potential

We start today off with a Flash Flood Watch in effect for our entire area. This runs from noon today through noon tomorrow.

That’s been issued ahead of a strong frontal system that will give us the potential for heavy rain over the next 24-36 hours.

Out ahead of this system, winds will be out of the south, allowing temperatures to approach the 60º mark during the day today. Daytime heating should be limited by cloud cover, however, as the storm system draws near. This system has quite a bit of moisture associated with it and it will begin to impact us in earnest overnight tonight and through tomorrow morning.

With that rain shield over us for quite a long amount of time, it won’t be hard to see quite a bit of rainfall. The high-resolution NAM has us nearing three inches of rainfall which would easily cause flooding.

Because of this, the Weather Prediction Center has placed many of us in a Moderate Risk for Flash Flooding through this weekend.

Remember as always, Turn Around, Don’t Drown and don’t drive through flooded roadways. You never know how deep the water really is.

Weekend Turns from Wet to Cold

The cold front will pass us by on Saturday and when I say cold…I mean cold.

Winds will shift around to the northwest through the morning, ushering in much colder air from Canada…this means our high will occur relatively early in the day as the temperature falls through the afternoon. Our actual high will top out near the 50º mark in the morning before falling into the lower 40s by evening.

Cloudy, Cool, and (Mostly) Quiet Christmas Eve


After the tumultuousness of the beginning of the weekend, it will be nice to just put the weather on the back burner (for the most part) and enjoy some quality time with family and friends. We’ll break out into partly cloudy skies with highs around the 40º mark during the day. But…there’s a catch.

A weak disturbance will move through late Christmas Eve night…and with that will come the chance for a snow flurry or two late Sunday night and into early Christmas morning.


The good news (or bad news, depending on whether or not you’re a snow lover and/or wanted a White Christmas) is that it shouldn’t amount to much if anything, but it could cause a slick spot or two if you’re headed out to a late church service Sunday night or an early Christmas service.

Otherwise, Christmas looks sunny, bright and cool!

That just about does it for me! Thanks for checking into wxornotBG this morning, and be sure to follow @wxornotBG on Twitter for real-time updates on our flooding potential throughout the day. Have a terrific Friday and Merry Christmas!
