Updated at 635 PM CST SUN NOV 16 2025 - A cold front will bring a milder airmass on Monday. Otherwise, unseasonably warm conditions are expected through the next 7 days. - There is potential for an increasing fire weather risk on Monday as much drier air moves into the region. && .DISCUSSION... (This afternoon through next Friday) Issued at 1101 AM CST SUN NOV 16 2025 Another pleasant day is unfolding across Central Alabama as a cold front pushes through. A low level cloud deck remains in place ahead of the boundary where a thin low level convergence axis is maximizing the Little moisture available across the state. The front will continue to move south through the day, eventually stalling along the Gulf coast. Much drier air will filter into the region in the wake of this boundary. This will allow for temps to drop into the low to mid 40s for most tonight. Minimum relative humidity values tomorrow fall in the 20- 25% range for most of the area. There is a possibility we could be even drier. HREF guidance is hinting at a low to moderate chance of RHs less than 20%. Luckily, winds are forecast to be light. We will be keeping a close eye on the trends tomorrow. The front will retreat back to the north on Tuesday in response to a shortwave and associated surface low moving across the Plains. As a result, we will see some pretty warm temps for November with highs in the low to mid 80s. By Thursday, a stout upper low will eject across the Four Corners towards the Plains. A few H5 impulses will race ahead through the end of the work week, leading to some low rain chances across our northwestern areas. Another cold front will be sent our way by the weekend, leading to low to moderate chances (30-60%) for showers and thunderstorms. There remains a good deal of uncertainty within the latest suite of guidance when it comes to FROPA timing next weekend. For now, rain chances look to increase on Friday and linger through the day Saturday. 95/Castillo && .AVIATION... (00Z TAFS) Issued at 635 PM CST SUN NOV 16 2025 VFR forecast is expected for the 24 hour forecast with surface high pressure behind a front. Winds will be generally light/variable through the forecast period. 08 && .FIRE WEATHER... A cold front is currently progressing across the region late this morning. Winds will shift to the north-northwest for this afternoon. A much drier airmass will arrive behind the front tomorrow with min RH dropping below critical thresholds for a few hours across much of the area Monday afternoon, contributing to a moderate risk of significant fire potential. However, winds are expected to remain well below Red Flag Advisory criteria during this time. Higher dewpoints will begin to return to the area on Tuesday, and we will see an improvement in min RHs with values ranging from 35-40% in the east and 45-50% in the west. && .PRELIMINARY POINT TEMPS/POPS...
