Best chance of rain in over seven months arrives next week

Cool, dry air moving in on a gentle breeze makes it colder tonight, and there will be a little chill in the air this weekend even during the day.

Temperatures fall to the mid-30s tonight with some scattered frost, and it only warms into the middle and upper 50s on Saturday afternoon. It gets even colder on Sunday morning: lows 25-30ºF for several hours before sunrise. The wind shifts around to the south on Sunday, and it starts to warm up a little, but there is a huge warm-up coming ahead of a major storm system on Monday. That system brings our best chance of rain since mid-April!

What to expect next week:  The last time it rained more than a quarter-inch over the entire Tennessee Valley was way back on April 11th: 1.10” in Huntsville that day.

Rainfall April 11-12, 2016 (the last time we had full coverage of rain)

Rainfall April 11-12, 2016 (the last time we had full coverage of rain)

That’s almost two-thirds of this year: 7 months and fourteen days. We still have two more totally dry days (Saturday and Sunday) and one mostly dry day (Monday) before heavy rain and thunderstorms move in Monday night into Tuesday morning. The wind really cranks up ahead of the system Monday: gusts potentially above 40 MPH Monday afternoon and evening.

This is NOT a high-end, extreme severe weather event. There could be a few stronger storms with high wind gusts, but the biggest impact from this system will be heavy rain: up to two inches in spots through midday Tuesday.

Another wave of rain develops south of us Wednesday morning and spreads northeast. At this point, the greater chance of another 1-2” of rain comes over Northeast Alabama; however, the specific location of the heavier band of rain is still uncertain, so watch for adjustments as we work to refine the forecast for the middle of the week.
