Area Forecast Discussion National Weather Service Birmingham AL 1029 PM CST Sat Nov 30 2024 ...New AVIATION... .SHORT TERM... (This evening through Sunday) Issued at 550 PM CST SAT NOV 30 2024 Only minor adjustments needed in the temperature and dewpoint trends this evening as many locations have seen a sharp increase in dewpoint over the past couple of hours. Freeze is still expected for much of the area. 25/Owen Previous short-term discussion: (This afternoon through Sunday) Issued at 1220 PM CST SAT NOV 30 2024 Key Messages: - A widespread freeze is forecast across the entire forecast area again tonight. This afternoon. An elongated upper low remains over Southeast Canada while longwave ridging extends from over Western Mexico and extends northwest over Southwest Oregon.Surface high pressure was centered to our northwest over North Mississippi. Expect only some high clouds over the area today with dry conditions. Winds will be from the northwest at 4-8 mph. High temperatures will range from the upper 40s far north and in the higher elevations east to readings in the upper 50s far southwest. Tonight. A shortwave disturbance in the northwest flow aloft over the Central Plains early this afternoon will swiftly move east over the Tennessee Valley tonight as the expansive upper low remains well to our northeast while amplified ridging becomes centered over the Desert Southwest. Surface high pressure will become centered across the Deep South while a reinforcing cold front moves southeast from the Central Plains toward the Mid-South Region toward midnight. Look for mostly clear skies overnight with a few more clouds over the north and northwest late as a dry cold front nears from the northwest. Winds will be from the southeast at 3-6 mph. Another widespread freeze is forecast across the area with lows from the mid 20s northeast and in the higher elevations east to readings near 30 across portions of the southeast. Sunday. A longwave trough will extend from over Eastern Canada southwest to over the Mid-South Region Sunday with amplified ridging extending from over Northwest Mexico stretching northwest to over much of Oregon. Strong surface high pressure will extend from Central Canada southeast to over the Middle Mississippi River Valley Region. Skies will range from mostly sunny south to partly cloudy over portions of the northern half of the area Sunday while a surface cold front moves southeast through the area in dry fashion. Winds will be out of the southwest ahead of the front, becoming northwest behind it with speeds from 4-8 mph. High temperatures will range from the lower 50s far northwest to near 60 generally near and south of the U.S. Highway 80 corridor. 05 && .LONG TERM... (Sunday night through next Friday) Issued at 130 PM CST SAT NOV 30 2024 Key Messages: - The period of subfreezing low temperatures will continue into the middle of next week with some locations potentially experiencing a hard freeze on Monday night. - Persons should take steps to protect pipes in exposed or unheated locations, provide a safe and warm location for cold-sensitive pets, and ensure safe heating sources for themselves and those without adequate resources. Overall pattern remains the same as the previous forecast at least through Wednesday afternoon. There is still some timing and strength issues with the next system Wednesday night/Thursday and therefore timing issues with Friday into next weekend as well. At this time, trends of the forecast is that a warm front will try to lift up into the area after Midnight Wednesday night/Thursday morning. This should cause temperatures to rise a few degrees. Look for Midnight lows just above freezing before the rain works into the area. A slower timing will allow another freeze for areas in the north, but the precipitation would hold off until daylight hours. Current forecast accounts for a faster solution, with the temperatures warming overnight. With this forecast, the cold front works into the area during the day Thursday and could clear a big portion of the area Thursday night into Friday morning. However, the slower solution would keep rain overnight, but warmer temperatures. The slower model has sped up some with the latest model runs and is a middle ground of the fast and slow runs. Will trend drier on Thursday night, but warmer than the GFS. Still quite a bit of time before the systems get here, so hopefully we will get a better consensus quickly and can have some higher confidence for the end of the period. . 16 Previous long-term discussion: (Sunday night through next Friday) Issued at 229 AM CST SAT NOV 30 2024 A cold, multi-day period of west to northwesterly flow is expected to continue into the first part of next week as longwave ridging builds over the Desert Southwest while longwave troughing covers much of the eastern CONUS. High pressure will expand across the region, maintaining a regime of cold air advection which will support chilly days and cold nights. Subfreezing temperatures are expected each night Monday through Wednesday. The surface ridge will shift east of the area towards the second half of the week. A reinforcing cold front is expected to arrive on Thursday, although moisture return appears to be quite limited, and model solutions diverge significantly on whether or not any appreciable rainfall will accompany the front or how far south the front will progress before stalling in an east to west orientation. Some rain chances could persist into the end of the week depending on where the front settles which is dependent on the strength of a low-level ridge which will be centered over the Gulf of Mexico. Will maintain Chance PoPs Wednesday night through Friday, but refinements of the PoP forecast will occur as model continuity improves. 86/Martin && .AVIATION... (06Z TAFS) Issued at 1026 PM CST SAT NOV 30 2024 VFR conditions expected through the next 24 hours. Generally light to calm winds through 16-18z before becoming more westerly at 5-7kts. By 00-05z winds should become light to calm again. Some high clouds might move in across the northern half of Central AL during the day tomorrow, but these should remain above 25kft. 25/Owen && .FIRE WEATHER... For tonight, RH values will rebound from the low to mid 20s to the upper 70s to low 90s across the area. Afternoon RH will drop into the middle 20s south to middle 30s north on Sunday and Monday as the dry and cold, rain-free forecast continues. 20 foot winds remain below 6 mph. A return of moisture is expected by early Thursday morning and continue through next weekend. && .PRELIMINARY POINT TEMPS/POPS...
