DISCUSSION

(Tuesday through next Monday) Issued at 1011 PM CST MON NOV 9 2026

We were treated to a pleasant November day across Central Alabama today with high temps settling in the mid 70s under mostly sunny skies. We won't be quite as cold tonight with lows dropping into the low to mid 40s. Water vapor imagery this evening reveals a southern stream trough over Texas that will head our way through the middle of the week. If we peek far enough west, we can see a stronger upper low begin to make its way towards the Pacific Northwest. This southern stream system will pass through the area late Tuesday through Wednesday, bringing some mid and upper level clouds to the region. We will continue with a low chance for light rain/sprinkles (potentially virga) as guidance can often underdo QPF in these scenarios.

The stronger northern-stream shortwave trough will bring a clipper-like system and strong cold front into the area Wednesday night into Thursday. Low-level moisture return will be lacking ahead of the front with dew points mainly in the low to mid 50s, but strong forcing and steep mid-level lapse rates will be sufficient for a few showers Wednesday evening into Thursday morning. There may be just enough instability for an isolated thunderstorm across our northern areas, but severe storms are not expected at this time. A much cooler air mass moves in behind the front, with highs in the 50s and high chances for the first freeze of the season across at least northern portions of the area. Latest NBM probabilities maintain a 60-90% chance for freezing temps across the northern half of the CWA.

VFR conditions are expected for the next 24 hours with near calm to light/variable winds this afternoon and tonight. WRLY winds 4-9kt pick up toward midday Wed ahead of our next system. A few mid to high clouds may be noted at times. Low rain chances return on Wed morning with an upper system ahead of a front, but are too low to pinpoint and include in terminals ATTM.

FIRE WEATHER

RH values drop into the 25 to 35 percent range this afternoon. However, light winds will help negate fire weather concerns. Moisture increases on Wednesday ahead of a cold front with a few light rain showers at times Wednesday afternoon through the pre- dawn hours Thursday morning. We will need to keep an eye on Thursday for increased fire weather concerns as northwesterly winds increase in the wake of the front. Drier air and cooler temps return this weekend.
