Area forecast discussion, Jan 10, 11:09 PM CST, 1 hour 56 minutes before
Area Forecast Discussion National Weather Service Birmingham AL 1109 PM CST Wed Jan 10 2024 ...New AVIATION... .SHORT TERM... (This afternoon through Thursday) Issued at 1215 PM CST WED JAN 10 2024 Tranquil weather has returned across Central Alabama today, at least temporarily as we transition between very dynamic weather systems within a progressive flow aloft. Surface high pressure is centered over the the northern Gulf Coast, with a southwesterly flow developing at the surface. A dry and cool airmass has filtered into the region behind Tuesday's system, with dewpoints expected to mix down into the upper 20s and lower 30s this afternoon. 1000-850mb thicknesses are supportive of highs ranging from the mid 50s south to the upper 40s north. Lows tonight should be able to dip down into the 30s with radiational cooling and mostly clear skies. We'll likely see some locations that stay mixed overnight and some that are able to decouple the boundary layer and drop below freezing. Gadsden, Jasper, and Haleyville will likely be some of our colder spots by sunrise on Thursday. Warming temperatures can be expected during the day on Thursday as we transition the airmass ahead of the dynamic system that is expected to arrive on Friday. Southerly to southeasterly flow will increase Friday afternoon with low level moisture also on the rise. As dewpoints rise into the 50s across the southwest counties, warm air advection will also help to warm afternoon highs into the 60s in most locations. High cirrus clouds are expected to increase in coverage as upper level southwesterly flow begins to ramp up as the upper trough axis ejects eastward from Texas and Oklahoma. Rain chances will remain west of Central Alabama through the day on Thursday. 56/GDG && .LONG TERM... (Thursday night through next Tuesday) Issued at 307 PM CST WED JAN 10 2024 A complex and busy weather pattern is in store for the end of this week through early next week. First, a trough is expected to quickly move through the region on Friday. The overall forecast and expectations for this system haven't changed much from the previous forecast, and the previous discussion below covers the details very well. Overall, there's a severe potential for much of the area with the biggest uncertainty being whether the warm sector will be able to lift far enough north before being cut-off, and that will determine the northern extent of the severe threat. Second, this system is another deepening low pressure, which will lead to increased gradient winds for much of the day on Friday. Even for areas that don't see severe weather, strong winds will be capable of bringing down trees and causing power outages. Winds could gust 45-50 mph at times for most of the area. Third, on the backside of this system, very cold air moves into the area and a secondary trough dips through the Mid-MS Valley on Monday. Guidance continues to hint at winter precipitation across our northern counties, especially the northwestern counties Sunday night into Monday. I've continued with having rain, snow, and sleet mentioned in the forecast, but have added a low chance of freezing rain in the northwestern counties for a few hours early Monday morning. There's still some uncertainty with this, as with any winter forecast in Central AL, but model trends have been fairly consistent with showing this potential. Finally, if the first three punches weren't enough...that secondary trough brings in an even colder air mass into Central AL Monday through at least Wednesday morning. Low temperatures Monday night could be in the teens for much of the area with our northern counties dropping into single digits. The cold air persists for several days. It's possible that some of our colder locations in the north and higher terrain areas remain below freezing for over 48 hours. This is reminiscent of our cold snap around Christmas in 2022. The exact temperature forecast will likely change in coming days, but confidence is fairly high for dangerously cold temperatures early next week. 25/Owen Previous long-term discussion: (Thursday night through next Tuesday) Issued at 354 AM CST WED JAN 10 2024 Within broad troughing covering much of the CONUS, a potent but relatively low-amplitude trough will round the base of the large scale trough Thursday night. It will lift quickly northeastward with a negative tilt across the Mid-South and northwest Alabama Friday morning, accompanied by a 120kt mid-level speed max on its southeastern flank. Lee cyclogenesis will take place in eastern Colorado Thursday, with the surface low hooking through Oklahoma into the Ozarks by Friday morning. The surface low will quickly deepen about 20 mb in 24 hours Thursday night through Friday night as it lifts northeastward to Michigan. A 70kt pre-frontal 850mb LLJ will move across Alabama Friday morning. A cold front and possible pre-frontal trough will move eastward across Alabama on Friday as a warm front lifts northward. While there are some similarities to yesterday's system in the track of the low, there are also some important differences. While there will be a subtropical impulse over the Gulf, it will be located further to the east towards the Florida peninsula and probably not be a factor causing disruptive coastal convection. Also the trough will be further to the north and negatively tilted, in a placement typically more favorable for supercells in Central Alabama, with even global models indicating convection being more cellular. Elevated convection north of the warm front will also be developing overtop of the CWA rather than south of it. Thus models are indicating a narrow but relatively robust warm sector with 62 to 65 dew points lifting northward into at least our southern counties, with around 500 to 1000 J/kg of SBCAPE. As is typical, shear will be more than sufficient for organized storms with 0-6km bulk shear values around 90 kts, though it's possible that this shear could be too strong if updrafts aren't strong enough to avoid being sheared apart. The main question will be how far north the warm front will lift, especially if it will lift into the area of strongest forcing, and whether storms will out-run the relatively small warm sector. Will note that while the 500mb shortwave will be lifting quickly northeastward away from the area by midday, there is still a pronounced 700mb trough to our west aiding forcing, with some 500mb height falls continuing through the afternoon. It's also worth noting that some models may be veering winds too quickly at the surface given the isobaric response to the deepening low to our northwest. Overall this is a low floor but relatively high ceiling event, as any supercell that is able to remain sustained in the warm sector before crossing to the cool side of the front would have a conditional threat for a strong tornado. This will be a fast-moving system, with the main severe threat starting as early as 8am-9am in the west (though there could be some elevated hail-producing storms as early as 4-6am), and ending by 3-4pm in the east. While I know there is a lot of chatter regarding whether or not we will see a wintry mix next week as discussed below, we really need to remain focused on this severe threat. Will have to keep an eye out for any flooding with any training storms given the heavier rainfall we just had, but widespread heavy rainfall is unlikely given the more cellular convection and progressive nature of the system. Additionally, we will also need another wind advisory as conditions will once again remain supportive of gusts to 35 to 45 mph, higher than that at higher elevations. Cool and dry conditions are expected over the weekend, before attention turns to an Arctic air mass approaching from the northwest. There continues to be a lot of ensemble spread in solutions, and it is important to not focus on any one deterministic solution this far out. Some of this spread appears to be sensitive to a small-scale shortwave coming out of the North Pacific which will not move onshore over the Pacific Northwest until Saturday afternoon, and how quickly it shears out as it interacts with the large trough over the CONUS. This would impact the amplitude of a potential trough to our west by Monday. This will impact whether any waves of low pressure slow the progression of the Arctic front as well as moisture availability along the Arctic front. With this being a shallow cold air mass (which models often struggle with), initial frozen precipitation types if they occur would be more in the form of freezing rain or sleet, with snow only possible if moisture extends far enough back in the cold air mass. Keep in mind that model accumulation maps often aren't very accurate in mixed precip events. Will mention a chance of a light wintry mix in far northern Central Alabama in the HWO for the late Sunday night through Monday timeframe but emphasize that any accumulations or impacts remain uncertain. Additionally, hard freeze warnings will probably be needed across at least portions of the area Monday and Tuesday nights, with wind chills also near advisory criteria in the northwest counties Tuesday morning. 32/Davis && .AVIATION...
