Brief wave of showers breaks the dry spell soon

A Freeze Warning is in effect from 1 AM to 9 AM Wednesday

How about that chill Tuesday morning? Temperatures dipped as low as 24ºF in Russellville, 26ºF in Cullman and Valley Head, 29ºF in Decatur and 32ºF in Huntsville. The average latest freeze in North Alabama comes in the first two weeks of April, so this is probably not that last cold snap we’ll have!  Expect another freeze in spots tonight; lows drop to the low-30s with a light wind, a clear sky, and a Freeze Warning in effect:

Spring officially begins at 4:58 PM Wednesday; it will be warmer Wednesday with a partially sunny sky: highs in the lower and middle 60s with a light south breeze. A weak cold front coming in from the northwest brings a brief, light band of showers that will technically end our dry spell at six days if so much as a trace of rain falls at Huntsville International. If you miss the rain (which is possible late Wednesday night), you won’t likely see rain again until Sunday night at the soonest.

The rest of this week: On our Seven Day Forecast, there’s a 10% chance of rain on both Wednesday and Thursday. Don’t think of that as two separate days with a chance of rain; it’s more like one wave of light showers that begins after 10 PM Wednesday and ends before sunrise Thursday. Most of both days will be completely rain-free.

Clouds clear Thursday, but it does turn cooler! We’ll drop to the upper 30s again on Friday morning before a solid warm-up begins. Highs jump back to the lower and middle 60s Friday afternoon with a light north wind.

Weekend outlook: It’s beginning to be yard work season, soccer season, (and it’s already) baseball and softball season. This weekend provides a great weather setting to be outdoors. The pollen count will be high, the pine pollen that covers everything in that yellowish-green powder will become thicker, and there is no chance of rain to settle it down until Sunday night.

Expect a fair, mild Saturday: cold in the morning (around 40ºF at sunrise) to around 68ºF in the afternoon with a light northeast wind. Clouds thicken some on Sunday, but there’s still enough sun and a southeast breeze to push the mercury up over 70ºF in Huntsville, Decatur and The Shoals (most of Northeast Alabama and Southern Tennessee will stay cooler in the 60s).

While some showers are possible after 6 PM Sunday, the best chance of any measurable rain this weekend comes over the northwestern corner of Alabama, Mississippi and West Tennessee.

Rainy start to next week: Showers become more common Monday and Tuesday of next week, but there is still no immediate threat of heavy rainfall or severe storms! Total rain through next Tuesday looks a little below average for this time of year: around 0.5” to 1.0” in all.
