Temperatures will fall into the middle and upper 40s overnight tonight before the wind begins to increase Monday morning. The sky will remain mostly cloudy for much of the day on Monday but as the wind increases to near 20 mph the temperatures will warm up into the middle 60s. Afternoon highs will reach close to 71 degrees. The wind will continue to increase from the south as a line of strong thunderstorms with heavy rain and gusty winds moves across North Alabama from west to east. It looks a line of heavy rain and storms could hit the Shoals as early as 5-7pm Monday and quickly track east.
Time of arrival for the strongest winds and heaviest rain: Shoals 5-9pm… HSV Metro area 6-10pm… NE Alabama 7-11pm. Keep checking back for updates on this developing storm system. A High Wind Watch has been issued by the National Weather Service for NE Alabama and parts of Middle Tennessee. We are expecting sustained winds at 25-35 mph with gusts 40-50mph by Monday afternoon and into evening hours ahead of the main line of storms. Wind gusts in higher elevations could reach 55 mph. Isolated power outages are possible along with locally heavy rain. Threat for flash flooding is low however. There is also the potential for what is called a gravity wave/wake low event. If that happens it could lead to more trees being downed. The spin up, EF0 type tornado threat is low but cannot be ruled completely out. Storms and high wind should be gone by 3am Tuesday. More storms likely Tuesday night into Wednesday morning.
Most of the day on Tuesday will be rain free with highs reaching the lower to middle 70s. The atmosphere will become more unstable into the evening hours as another storm system moves in from the southwest. Strong to severe thunderstorms with locally heavy rain, hail and wind gusts up to 58 mph will be possible late Tuesday night into Wednesday morning. The timing on this system continues to show some signs of being delayed so keep checking back for updates. Additional 1-3” of rain will be possible with this system through Wednesday morning.
The weather returns to normal for Thursday and Friday but more rain is expected over the weekend.
Have a great night.
