In addition, steep low level lapse rates and seasonably dry low levels due to deep mixing in the wake of the surface cold front are fostering optimal conditions for evaporational cooling beneath cloud bases, which has promoted gusty winds beneath these storms. That same lingering cloud cover, combined with continued cool advection in the wake of the gradually eastward shifting upper trough, will result in daytime temperatures running 10- 15 degrees below normal for mid April with forecast highs in the mid to upper 50s. Forecast lows in the mid 30s suggests some frost which could pose a risk to tender, newly emerged vegetation; while dewpoints should hover in the low to mid 30s in the St.
Troughing remains over the eastern part of the country this afternoon while at the surface, Florida sits in between high pressure to the northeast and a trough near the Bahamas. For the afternoon and evening, a cold front will move over the peninsula, with isolated/scattered showers and a few storms expected, mainly over the Nature Coast. High pressure moves in for the weekend, with pleasant and dry weather expected.
A broad low and upper level trough over the Great Lakes will push a cold front into our area later this evening. Scattered showers and thunderstorms will fire ahead of this front and as a trough axis moves in mainly after 3-4 PM. The trough axis will linger over Middle TN into Friday. Lows tonight fall into the 40s and cooler weather returns Friday with highs only in the upper 50s to lower 60s.
(This evening through Friday Night) A deepening upper level trough digging southward from the Great Lakes to the Ohio Valley and towards the Appalachians will, as anticipated, swing a mostly dry cold front across the Mid South this evening and out of the region overnight. However, this morning's GFS run was more aggressive in the westward extent of the moisture emanating from the severe weather which will be in progress over the lower Mississippi and Tennessee valleys this evening.
306 PM CDT Thu Apr 10 2025 Global guidance still shows a cold front grazing the far northeast portions of our CWA, introducing a decent chance for some scattered showers and thunderstorms later this evening. At the same time, a positively tilted trough continues to hover over the Upper MS Valley/Midwest. The aforementioned trough axis will advance southeastward towards the OH/Lower TN Valley Region heading into the overnight period. Within the base of this trough, hi-res guidance is highlighting a 80-90kt jet from the ArkLaTex region tracking southeastward across the southeast CONUS. This will allow for areas along and north of I-20 to see dewpoints in the low/mid 50s as the cold front propagates southward across our CWA. Expect overnight temperatures to fall into the low 50s areawide.

RGass (Today and tonight) A progressive longwave pattern, with our area situated on the backside of a flattening upper level ridge, will continue to steer more impactful troughing to our north. A trough axis well to our north will move inland this afternoon and push a weak and dry cold front south into our area tonight. The cooler and more importantly, drier airmass will help limit widespread stratus development late tonight into early Friday morning.

641 PM EDT Thu Apr 10 2025 - Warmer conditions arrive this weekend with dry weather tomorrow into the weekend. North to northeast flow will hold some clouds over the area into tomorrow morning within the cold thermal trough, though some clearing should occur across the Thumb and Saginaw Valley tonight resulting in cooler overnight lows tonight in the upper 20s down into the higher elevations. Thermal troughing remains over the Great Lakes tomorrow, but slight recovery will occur as the mid and upper level ridge starts to fold across the Midwest. The late week western CONUS ridge further folds into the Great Lakes over the weekend continuing to moderate the overall airmass as 850 mb flow backs from northerly to the west.
High pressure aloft will contribute to a shallow marine layer with foggy conditions near the beaches through Friday as well. Low clouds and fog will move further inland by the weekend as a troughing pattern sets up across the region. WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO An area of high pressure centered over Baja California is currently peaking in strength. Like today, highs will again be near 90 degrees from the high desert, Inland Empire and far inland valleys/foothills of SD County. A trough off the coast will move closer to the region by the weekend, bringing temperatures down by 5-10 degrees from where they will be on Friday. The troughing pattern will also bring windier conditions across the mountains and adjacent deserts as NBM and WRF models show chances of seeing wind gusts over 30 MPH.
954 PM EDT Thu Apr 10 2025 A low pressures system moving through the Tennessee Valley will bring a chance of showers to areas along and south of the Ohio River tonight. High pressure and a dry but cooler airmass will build into the region for Friday. With a fair amount of lingering low level moisture, clouds will persist through the morning hours and into early afternoon, but we may begin to see a decreasing cloud trend from the west later in the afternoon as the high builds in. As the high moves overhead Friday night, mostly clear skies and decreasing winds are expected. This will lead to areas of frost late as temperatures drop into the low to mid 30s.

Hot and clear sky conditions moving out tonight, with cooler temps and cloudy skies moving in Friday.
High pressure continues to hold over the region this evening with warm temperatures. The next cold front is set to approach the nature coast tomorrow afternoon. SPC has the northern nature coast in a marginal risk for severe thunderstorms late tomorrow, although that will be dependent on the band of showers/storms currently well to the north of the area holding together and reaching the nature coast ahead of the cold front as U/L energy will be lifting well to the northeast of the area at that time.
359 AM CDT Fri Apr 11 2025 Today through tonight: A longwave upper level trough over the eastern half of the CONUS will shift eastward to the Atlantic Coast as we finish up the week and go into the weekend. Cyclonic flow on the western periphery of the trough will support isolated diurnal shower activity over northeast portions of the area, but otherwise, the most notable weather today should be related to the gusty northwesterly gradient winds. Reinforcing cold fronts will keep drier air locked in for much of the period.
