1104 AM EDT Fri Apr 12 2024 Light rain showers will continue throughout the day as low pressure exits to the east and a large upper level wave crosses the region. Much cooler air will settle in today and remain through Saturday. Gusts >40 mph may bring trees down given the highly saturated ground. The trough axis stretching south of the low will push through the region this afternoon. Colder air will overspread the region throughout the day, with the coldest reaching the area this afternoon with the trough axis.
Gusts up to 40 mph will remain possible into the afternoon until the low moves far enough away and the pressure gradient relaxes enough to reduce the winds. All of this activity will continue into the afternoon before diminishing by early evening as the low continues shifting eastward along with the loss of daytime heating. (Saturday through next Friday) After tonight, a big warmup is in store for Middle Tennessee as an upper ridge builds over the western Gulf Coast into the Tennessee Valley.
A pronounced ridge sits over the InterMountain West with dry, northwesterly flow aloft across the Midwest into the OH/MS Valleys. MJ Dry and cool weather will prevail through the weekend as upper level ridging dominates.
(Rest of Today) A closed mid/upper-level cyclone will lift east-northeastward from the Lower Great Lakes over the course of the day, with a well- defined vort max peripheral to the low (evident in current water vapor satellite data) currently digging southeastward from the Lower OH Valley.
Mid level trough over the area today will swing east tonight with the mid level winds tending to shift to more northwest by Saturday morning.
An upper level ridge will encompass much of the center of the CONUS. However, a weak short wave trough will be under-cutting the upper ridge. Downsloping winds will also lead to much warmer temperatures with widespread values in the 80s and possibly lower 90s off the Caprock.
With temperatures already climbing into the upper 60s as of the 15Z hour, elected to boost today's afternoon high temperatures 2-3 degrees, with area sites achieving values well into the upper 70s and lower 80s, if not a degree or two warmer at some sites. This is due to surface ridging gradually transiting across the area and settling in by this afternoon, allowing for calmer winds (5-10 mph) after a few blustery days. This is due to robust troughing that makes its way across the Intermountain West, re-emerging across the southern Great Plains and creating a more significant severe weather threat across Central Oklahoma.
A beautiful, dry weekend ahead with highs in the upper 70s to low 80s as high pressure dominates the region.
high pressure quickly follows in the wake of the FROPA and ushers drier air from the north. North- northwesterly winds will remain around 10-15mph this afternoon, helping in keeping afternoon highs in the low-mid 80s. For Saturday, models intensify and expand the high pressure cell over the SE CONUS and into the state, with SFL in the southwest periphery of the high. This will again help in keeping afternoon temps in the lower temps across much of SFL.
Weak high pressure will begin to build over the region today and last throughout the weekend, bringing with it a warming and drying trend.
The Northern Rockies will be transitioning to zonal (westerly) flow this week as a large low pressure system digs southward along the Pacific coast and moves inland over California.
Surface analysis depicts high pressure across the area, centered over the NW Gulf, yielding light and variable winds.
259 PM CDT Fri Apr 12 2024 - Warmer temperatures with highs reaching the 80s and 90s this weekend, near record values.
Pattern Synopsis/Pattern Forecast: All eyes directed at one deep (and deepening) circa 978mb low pressure working its way slowly north on the east side Georgian Bay early this afternoon. Aggressive deformation/trowal within attendant deep mid level troughing brought widespread light and moderate rain to much of the Northwoods last night through this morning. High pressure and drying through the vertical resulting in a steady decay of this precipitation from west to east across the region early this afternoon. Significant changes expected as we head through tonight as eastern lakes low pressure begins to pick up its northeast pace. Pattern Synopsis and Forecast: Low pressure system producing the rain showers today (Friday) will continue to pull away on Saturday as heights rise and northwest flow aloft takes over.
(Today through Saturday) As the morning begins, the axis of a longwave trough covering much of the eastern CONUS has cleared Georgia to the east. As a low pressure system associated with the trough begins to move northeastward into Canada, another cold front has moved through the forecast area. Northwesterly flow behind this front will usher in a cooler and drier airmass, which will persist through the short term period. Relative humidity values are will range from 25-35 percent across the area this afternoon, with the lowest values in central Georgia. Winds will diminish overnight, with gusts coming to an end after midnight, as upper level ridging approaches from the west and high pressure settles in over the Southeast. With increasing 1000-500 mb heights as the ridge builds into the region, a warming trend will begin during the daytime on Saturday.
Cooler temperatures and gusty winds are expected through the weekend.
1231 PM CDT Fri Apr 12 2024 (Today and tonight) High pressure continues to build across the area today, continuing the warming trend that is expected to continue for the next few days.
With temperatures already climbing into the upper 60s as of the 15Z hour, elected to boost today's afternoon high temperatures 2-3 degrees, with area sites achieving values well into the upper 70s and lower 80s, if not a degree or two warmer at some sites.
328 PM EDT Fri Apr 12 2024 Strong winds and a few showers will linger into this evening in the cool westerly flow behind departing low pressure. Decreasing winds and clouds can be expected tonight as the low pushes farther east. High pressure is forecast to provide dry weather on Saturday.
239 PM EDT Fri Apr 12 2024 (This afternoon through Saturday) 500mb trough currently moving across northern GA. The parent upper low is centered across the northern Great Lakes. At the surface, a strong low pressure system has moved into southern portions of Canada. High pressure currently just offshore the SW LA coast will continue to build in from the SW tonight. The high center should remain just offshore the Gulf Coast through the period.
(This evening through Saturday) Southerly winds will stay up a little bit tonight which will keep overnight lows around 15 degrees warmer tonight than they were this morning. Speaking of temperatures, warmer temperatures are expected Saturday with highs in the 80s to near 90 across the area.
First, the weak clipper system that will bring the low chance of showers late tonight will linger into the day Saturday (again, mainly along and north of highway 2).
1143 AM CDT Fri Apr 12 2024 (Today through Saturday) Mid-level low shifts eastward today allowing ridging to build in. At the surface, ridging will be shifting east of the area bringing a return to steady onshore flow, and as a result an increase in low level moisture. In addition to gusty winds today, will see them again tomorrow as low pressure strengthens to the west. Temperatures today will be near normal with highs mainly from the upper 80s west to the lower 80s east. Tomorrow looks a degree or two warmer.
The high will lead to very optimal radiational cooling conditions with calm winds and clear skies, so temps were nudged down overnight tonight. The center of the high will continue to traverse eastward throughout the day on Saturday, transitioning us to onshore flow. The onshore flow will bring in warmer and more moist air into the area. The suppression of the ridge and the warm onshore flow led temps to be slightly bumped up from NBM, but not much. Although we will add heat and moisture into the area, it will not come close to overcoming the suppression of the ridge, let alone produce clouds, so expect another warm and sunny day tomorrow.
Upper level ridging is pushing east from the Rockies over the Great Plains this evening, and looks to bring its ridge axis over the ArkLaTex by tomorrow afternoon before upper level flow begins to flatten out somewhat, with a weak disturbance emerging over the upper plains and pseudo-zonal flow overhead for the Four State Region. The riding overhead and rebuilding southerly winds will enhance our established warming trend, with highs soaring into the low to mid 80s tomorrow afternoon.
Regardless, lows will be considerably warmer than they were last night in the 50s most places.
Sunny and much warmer Saturday with still breezy west winds. Discussion: Deep trough lies over the Eastern U. Dew points are in the 30s to the lower 40s. As the moisture moves out and upper trough shifts east tonight expect clearing from southwest to northeast. High pressure will build in from the southwest overnight and Saturday. Saturday with high pressure still building in it will still be breezy with wind gusts as high as 40 mph in the northeast in the morning and with much lower relative humidities around 30 percent. Discussion: At the start of this period, a large high pressure are will be centered near the Gulf Coast region, with a ridge axis extending northward to the Great Lakes.
1155 AM CDT Fri Apr 12 2024 (Today through Saturday) The upper low has worked its way to our east and skies have cleared across the area. As we move through the day the low will continue to move away, but gradient winds will remain high through much of the afternoon, before decreasing near sunset. A much calmer day on Saturday in regards to the wind as high pressure builds in. Overnight lows with clear skies will be in the low 40s. Highs on Saturday will be warmer with readings in the upper 70s to low 70s.
753 PM EDT Fri Apr 12 2024 Strong winds and a few showers will linger into this evening in the cool westerly flow behind departing low pressure. Decreasing winds and clouds can be expected tonight as the low pushes farther east. High pressure is forecast to provide dry weather on Saturday.
Above-normal temperatures will continue through this afternoon before an approaching area of low pressure brings cooler temperatures and gusty winds to much of the area on Saturday.

Currently - Beautiful conditions continue across the Keys due to the recent passage of a very late season cold front. Temperatures are in the lower to mid 70s with dew points broadly near 60. High pressure centered over the northern gulf coast will maintain moderate to fresh breezes, shifting from northwest to north to northeast.
622 PM EDT Fri Apr 12 2024 -Windy & cooler through Saturday with frequent gusts 40+ mph -Snow accumulation tonight-Saturday A.
The core of high pressure continues to slide eastward, from the current location of SE LA at 1024mb last hour in the Big Easy metro area, down the Gulf coast toward Mobile by daybreak. Current dew points lock in the possibilities with that scenario and we have bumped many locales up a couple or few degrees with some category changes slightly warmer.
1227 AM CDT Sat Apr 13 2024 (Tonight through Saturday night) High clouds will continue to move in from the west tonight as the mid and upper level ridging in place begins to flatten.

350 AM EDT Sat Apr 13 2024 High pressure will build into the SE US through the weekend.
(Today) At the surface, high pressure will continue to build in from the SW throughout the day today.
High pressure will otherwise build across and offshore the Southeast through the weekend. Showers over the mtns associated with DCVA as energy swings through the trough will dissipate as they move off the higher terrain in the downslope flow regime. The upper trough over the Eastern trough associated with the deep low pressure system moving north into Canada will pivot NE and away from the area today. Under clear skies, lows once again in the lower to mid 40s.
354 AM EDT Sat Apr 13 2024 Low pressure with a cold frontal boundary will gradually shift northeast of the area Saturday bringing one final round of rain and snow showers.
This evening the low will be centered just off the Alabama coastline resulting in light to calm winds. A weak inverted trough will develop to our east but the only impact we will see will be some passing cirrus clouds. On Sunday the high becomes centered off the west coast of Florida, so we will begin to see the winds shift to more of a southwesterly flow, but remain light. Even light winds of less than 4 mph could result in temperatures 5 to 8 degrees warmer in spots.
(Today through Sunday) High clouds will continue to move around weak upper level ridging across south-central Texas today. In the low levels, breezy southeast winds will develop today, with gusts to around 30 mph, as low level moisture gradually increases through the short term. High temperatures today are forecast to be in the low to mid 80s east to low 90s along the Rio Grande. Lows tonight slightly warmer, in the mid 60s to near 70s. Highs Sunday a couple of degrees warmer than today.
Temperatures around sunrise will vary from the 50s just to the west of Lake Okeechobee and across inland locales with the coastal communities remaining in the low 60s. High temperatures on both days of the weekend will remain seasonable in nature with forecast highs in the upper 70s to low 80s along the immediate east coast with slightly warmer temperatures (low 80s with perhaps a few locales in the middle 80s) inland and across southwestern Florida.
Surface analysis depicts high pressure across the area, centered over the NW Gulf, yielding light and variable winds. Little change is anticipated through the weekend, with a modest increase in low level moisture along with warmer temperatures expected.
(Today and tonight) Warm and windy conditions will continue through today and into tonight as high pressure continues to build across West Central Texas and the pressure gradient remains tightened over the area.
1230 AM CDT Sat Apr 13 2024 - Warmer temperatures with highs reaching the 80s and 90s this weekend, near record values.
The rest of the nighttime hours will be quiet with lows dropping into the low to mid 40s across the area. Gusts up to 40 mph will remain possible into the afternoon until the low moves far enough away and the pressure gradient relaxes enough to reduce the winds. All of this activity will continue into the afternoon before diminishing by early evening as the low continues shifting eastward along with the loss of daytime heating.
Deep low pressure continues to push NE away from the Great Lakes early this morning. Upstream narrow ridge axis extending from Central Canada to the Gulf of Mexico is edging eastward into the Western Great Lakes. Narrow ridge axis will slide over Michigan today. quickly followed by an area of deepening moisture around and ahead of a fast-moving low pressure system developing over the Northern Plains. clouds will rapidly increase later this afternoon and tonight with chances of showers increasing as the low center tracks thru Wisconsin and Lower Michigan. Short wave ridge builds in from the west yielding mainly precipitation free conditions (with the possible exception of a shower close to Lake Huron early Sunday) along with warmer temperatures through the period.
First, the weak clipper system that will bring the low chance of showers late tonight will linger into the day Saturday (again, mainly along and north of highway 2). For Sunday, not seeing any shower chances, but ridging does push closer.
Today and Sunday Expecting a relatively quiet Saturday across eastern Idaho as weak high pressure regains control across the region. Off the northern California coast, a potent upper low will move over CA later today and move through the Great Basin during the day Sunday. This will keep the region under strong southerly flow over the next few days keeping temperatures on the warmer side of normal. Temps today will again top out in the upper 60s to mid 70s in the lower valleys which is around 10-15 degrees above normal for this time of year.
100 AM CDT Sat Apr 13 2024 (Today and tonight) High pressure continues to build across the area today, continuing the warming trend that is expected to continue for the next few days.
Because of this, warmer temperatures can be expected in South Texas in the coming days. Highs will reach the low 90s in the Rio Grande Plains and the Brush Country today, with the Coastal Bend and Victoria Crossroads regions reaching the upper 70s to low 80s. By tomorrow, highs increase to the mid 90s out west, with our northeastern counties and coastal areas staying in upper 70s to the low 80s.
1059 PM CDT Fri Apr 12 2024 (This evening through Saturday) Southerly winds will stay up a little bit tonight which will keep overnight lows around 15 degrees warmer tonight than they were this morning. Speaking of temperatures, warmer temperatures are expected Saturday with highs in the 80s to near 90 across the area.
An upper-level ridge is starting to build in from the west as a trough axis propagates across New England. Regardless, values are in the lowest 10 percent, meaning today is unusually dry for this time of year. The upper-level pattern is flattening out and a broad upper-level ridge axis is expected to build over the Caribbean Sea and northward into the Gulf of Mexico.
The pattern will be characterized by an upper trough over the Great Lakes/New England regions with an amplified ridge moving out of the the Rockies into the Cntrl Plains. At the surface, winds will switch to the SW today as high pressure slides Ewrd towards FL. Tonight, lows should be warmer with readings staying in the mid 50s to near 60 degrees.
(Today and tonight) A little warmer today (lower and middle 80s most areas) with strong south winds. Breezy conditions expected to continue over much of the forecast area tonight, with some weakening across northwest parts of Oklahoma closer to a weakening trough of low pressure.
This will help afternoon highs warm into the low 80s to near 90 across the FA and will also help lower afternoon RH. Overnight lows will also be warmer, mid 40s across our northwest zones to around 60s across our southeast zones, as winds remain out of the southwest around 5-10 mph.
High pressure will move across the north Gulf coast and into the southeast U. Thereafter the high will continue to slide east, eventually settling across the western Atlantic, where it will wax and wane in strength.
Sunny and much warmer today with breezy westerly winds. Discussion: In the upper levels, a deep trough over the East Coast will be moving eastward today and a ridge will start to move into the region by this evening. At the surface, high pressure is over the Southeast and Ohio Valley. Today will be sunny and warmer with highs in the upper 60s and lower 70s. With ideal mixing conditions, westerly winds will be breezy today but not near as gusty as yesterday since the 850mb winds have decreased significantly with the departure of the trough.
1229 AM CDT Sat Apr 13 2024 (This evening through Sunday) A calm and drier period is expected in the short term as high pressure will takeover the weather pattern.
550 AM CDT Sat Apr 13 2024 (Today) At the surface, high pressure will continue to build in from the SW throughout the day today.
Weak high pressure overhead through the weekend bringing warmer and drier conditions.
634 AM CDT Sat Apr 13 2024 (Today through Sunday) High clouds will continue to move around weak upper level ridging across south-central Texas today. In the low levels, breezy southeast winds will develop today, with gusts to around 30 mph, as low level moisture gradually increases through the short term. High temperatures today are forecast to be in the low to mid 80s east to low 90s along the Rio Grande. Lows tonight slightly warmer, in the mid 60s to near 70s. Highs Sunday a couple of degrees warmer than today.
902 AM EDT Sat Apr 13 2024 High pressure will build into the SE US through the weekend.
(Today and tonight) The main rain band is moving inland along the cold front, bringing moderate rainfall. The cold front's parent low moves onshore and inland in the afternoon and into the night, providing additional scattered showers and storm chances.
Temperatures this afternoon should warm into the lower 80s (about 5 degrees above normal) at most locations as rising mid-level heights with a strengthening ridge and abundant sunshine affect the area.
An approaching area of low pressure will drop temperatures back to below-average this weekend and into the start of the work week.
