(Now through Tuesday) A cold front is approaching Deep South Texas, although, the only real relief it may bring would be drier air. Expect the mid- level ridge to strengthen back across Texas into Tuesday as Ian works into the Eastern Gulf of Mexico, bringing an end to the chance of rain locally. Temperatures will remain warm Monday and Tuesday, potentially a degree or two cooler based on cloud cover and any persistent rainfall.
616 AM CDT Mon Sep 26 2022 (Today through Tuesday) The cold front has moved through the area, and the drier and cooler air is already being seen with dewpoints in the upper 40s for some areas and temps in the mid to upper 50s so far early this morning. Model guidance shows dewpoints in the mid 30s for most of the mid state, and some enhanced mixing may get dewpoints to the low 30s. The northwest winds of 10 to 15 mph and gusts around 20 mph combined with the lower min RH values will bring marginal fire danger conditions today.
546 AM CDT Mon Sep 26 2022 (Now through Tuesday) A cold front is approaching Deep South Texas, although, the only real relief it may bring would be drier air. Expect the mid- level ridge to strengthen back across Texas into Tuesday as Ian works into the Eastern Gulf of Mexico, bringing an end to the chance of rain locally. Temperatures will remain warm Monday and Tuesday, potentially a degree or two cooler based on cloud cover and any persistent rainfall.
628 AM CDT Mon Sep 26 2022 Today and Tonight: Cooler and dry through the period. Early morning surface analysis had a dry cold front nearly along the Natchez Trace that will continue to move south through the remainder of the CWA this morning. Surface analysis also had a >1020mb high centered over the central Plains that will be aided by a deepening upper level trough over the region in bringing in cooler and drier air to our CWA. Guidance has come in a little cooler for lows Tuesday morning and our normally colder locations may bottom out in the upper 40s. Most sites wl see the lower 50s.
A deep upper lvl trof acrs the eastern half of the nation is fcst to weaken heading into the middle of the week, but still keep stable conds in place ovr the Mid-South.
Temperatures will be cooler than yesterday, with highs in the upper 70s to low 80s.
1040 AM EDT Mon Sep 26 2022 An upper level trough over the Northeast U.
At upper levels, an amplified ridge of high pressure over the Intermountain West coupled with a deepening trof across the eastern states will result in dry northwest flow today through Tuesday, transitioning to west northwesterly flow Tuesday night.
An upper level trough will continue to move east across and out of the region today. A much drier air mass is over the area and a slight cooler air mass is in place too. Highs today will be near to slightly below normal as highs warm into the lower to middle 70s. Temperatures will be a little warmer on Tuesday as highs warm into the middle 70s to the lower 80s.
533 AM CDT Mon Sep 26 2022 (Today) High pressure will reign supreme across eastern Oklahoma and western Arkansas today.
622 AM CDT Mon Sep 26 2022 (Today through Tuesday) A cold front has entered the northern part of our CWA and is stretched from near Georgetown to Rocksprings to western Val Verde County. Today's high temperatures will be cooler across the north where the front will pass early in the day and remain well above normal across the south.
407 AM CDT Mon Sep 26 2022 Today and Tonight: Cooler and dry through the period. Early morning surface analysis had a dry cold front nearly along the Natchez Trace that will continue to move south through the remainder of the CWA this morning. Surface analysis also had a >1020mb high centered over the central Plains that will be aided by a deepening upper level trough over the region in bringing in cooler and drier air to our CWA. Guidance has come in a little cooler for lows Tuesday morning and our normally colder locations may bottom out in the upper 40s. Most sites wl see the lower 50s.
731 AM EDT Mon Sep 26 2022 Aviation --Rainy weather will continue through the first half of the week-- A large upper level low will continue to dominate the weather pattern through the first half of the week. This low will be situated over southern Ontario and will move to the southeast as it slowly treks eastward. So this warm, moist air, some would say a thermal ridge, over Lake Michigan should be more than enough to break any mid to low level inversion and allow for thunderstorms over Lake Michigan today into tomorrow. --Improving conditions through the second half of the week-- As the upper level low moves eastward and tilts positively it will shift the moisture eastwardly, allowing for breaks in the clouds and a weakening of the gradient over the region.
The upper trough remains over the eastern CONUS with northwest flow overhead across the central part of the country with a predominant large-scale ridge over the western CONUS. Surface ridging continues to build into the region. The lower moisture content of the airmass also allows for overnight lows to drop to the 40s. By mid to late week, the upper pattern becomes a little more progressive with a ridge spreading east which will help temperatures increase but only slightly. The southerly flow increases as a lee trough deepens.
Only a few highs clouds were visible in eastern Iowa, northwest Illinois and far northeast Missouri early this morning on the GOES- 16 nighttime RGB, as high pressure was building into the area from the west. A beautiful day with a mix of clouds & sunshine is in store for the area with high pressure progged to slowly build into the Midwest. Otherwise, expect highs to climb into the lower to middle 60s, with lows tonight dropping into the upper 30s to lower 40s.
Today through Tuesday Pleasant weather continues over the next couple of days, as high pressure keeps skies clear and temperatures warm. Wind remains light through the period with high pressure keeping a weak pressure gradient in place.
346 PM CDT Mon Sep 26 2022 (Issued 345 PM CDT Mon Sep 26 2022) Tonight through Tuesday night: Light showers have developed this afternoon owing to daytime heating and some pockets of vorticity aloft spinning around broad trough aloft. After a similar day to today expected tomorrow, albeit drier as the low shifts east, a better chance for areas of frost will occur for areas west of I-41 as skies will clear, winds will ease to fairly light speeds, and with dry low lvls, temperatures will tank into the low to mid 30s.
235 PM CDT Mon Sep 26 2022 As of this afternoon, a potent upper trough is located across the Great Lakes region with northwesterly mid-level and upper level flow over the central plains. The overall pattern is set to remain in place as the Great Lakes trough pauses its eastward motion to dig into the Mid-Atlantic region. However, the upper ridge across the western CONUS will gradually translate south and east slowly putting the central plains under the influence of this ridge axis.
(The rest of today ) Post frontal surface ridging and dry air in place lead to some pretty chilly lows this morning across the region. Surface ridging will remain over the area today leading to abundant sunshine and relatively light winds.
221 PM MDT Mon Sep 26 2022 Upper ridging will continue to maintain influence over the western U.
116 PM EDT Mon Sep 26 2022 Cooler and at times unsettled weather will persist through Tuesday with chances for showers. Last impacts of the upper low will be taking shape to start the period as models continue to signal a long axis lake effect band of rainshowers (thankfully) setting up across western Lwr MI and then shift west with time.
This Week: A broad, midlevel trough currently from the Great Lakes into southeastern U. The 12z deterministic models differ on the track and timing of the low into the Great Plains this weekend. At the surface, a backdoor cold front will push west through the area on Tuesday with the coolest temperatures of the week (i.
308 PM EDT Mon Sep 26 2022 An upper level trough over the Northeast U.
312 PM CDT Mon Sep 26 2022 Tonight and tomorrow: A deep longwave trough will remain draped across much of the eastern CONUS with a cool and dry airmass locked in across the Lower Mississippi Valley beneath northwest flow aloft.
Clear skies, light winds, and temperatures in the low to mid-80s will be common this afternoon/evening. Similar to last night, the combination of the dry post-frontal environment, clear skies (radiational cooling), and light winds will allow temperatures to drop into the low to mid-50s areawide. By Tuesday, a western upper ridge will begin shifting overhead.
A slowing cold front will move south of the coast this afternoon, with more variable winds ahead and northerly 5 to 10 knots behind tonight into Tuesday.
--Rainy weather will continue through the first half of the week-- A large upper level low will continue to dominate the weather pattern through the first half of the week. This low will be situated over southern Ontario and will move to the southeast as it slowly treks eastward. So this warm, moist air, some would say a thermal ridge, over Lake Michigan should be more than enough to break any mid to low level inversion and allow for thunderstorms over Lake Michigan today into tomorrow. --Improving conditions through the second half of the week-- As the upper level low moves eastward and tilts positively it will shift the moisture eastwardly, allowing for breaks in the clouds and a weakening of the gradient over the region.
1217 PM CDT Mon Sep 26 2022 A cold front is located basically along the highway 190 corridor this morning and will continue to move south across the remainder of the forecast area today. Rua The long-awaited cold front is nearing central Louisiana, as noted by northerly winds and lowered dewpoints in the 50s and lower 60s near Shreveport. A deep trof spanning from the Great Lakes southward through Alabama/Georgia will drag the front down through our area this morning, with daytime temperatures only reaching the upper 80s to near 90. High pressure developing over the midwest in the wake of the front will slowly spread eastward, with northerly flow at the mid and upper levels to result.
235 PM CDT Mon Sep 26 2022 A trough aloft will gradually shift east of the area overnight into Tuesday, which will bring lighter winds and slightly cooler readings. High pressure at the surface will nose into the area on Tuesday and winds should remain mainly lighter than 15 mph.
Prevailing tranquil conditions will continue tonight into Tuesday as ridging aloft in the Intermountain West shifts slowly east into the Western High Plains. A weakening north-northwest flow aloft and drier air in the lower/mid levels will keep any precip chances out of western Kansas through the entire period. Ongoing warm/dry pattern will continue through the end of the week as medium range models indicate weak ridging aloft slowly breaking down as it drifts east across the Western High Plains into the Central Plains/Mississippi River Valley.
The upper ridge is covering the CWA. High pressure ridge aloft is anchored across Northern Rockies and Great Basin region this morning and will shift just slightly more over Colorado by later tonight. Temperatures will be warmer today as 700mb temperatures climb +3c over the region. This will support temperatures back into the lower to mid 80s across the plains and 60s and 70s over the mountains and high valleys.
Above-normal temperatures will continue the first part of the week as high pressure remains over the desert southwest.
The cold front that moved through the area late yesterday is now draped across far Srn AL and approaching the FL Panhandle, leaving clear skies and sunny conditions in its wake.
(This evening through Tuesday night) High pressure continues to dominate the western CONUS for the short term and into the extended. Lows will be a bit warmer through the week, but given the continued longer nights and light winds, that does the continued cooler trends. Given the continued high pressure over the area we'll continue to see above normal temperatures, with highs in the mid 80s to lower 90s.
1237 PM CDT Mon Sep 26 2022 (Today through Tuesday) The cold front has moved through the area, and the drier and cooler air is already being seen with dewpoints in the upper 40s for some areas and temps in the mid to upper 50s so far early this morning. Model guidance shows dewpoints in the mid 30s for most of the mid state, and some enhanced mixing may get dewpoints to the low 30s. The northwest winds of 10 to 15 mph and gusts around 20 mph combined with the lower min RH values will bring marginal fire danger conditions today.
Prevailing tranquil conditions will continue tonight into Tuesday as ridging aloft in the Intermountain West shifts slowly east into the Western High Plains. A weakening north-northwest flow aloft and drier air in the lower/mid levels will keep any precip chances out of western Kansas through the entire period. Upper level ridging will prevail over the Rockies through mid week. An upper level trough will move southeastward out of Canada into the upper Midwest by Tuesday, pushing a weak cold front through western Kansas. Ahead of the front, high temperatures will warm into the mid 80s to lower 90s Tuesday, with the warmer readings in Barber and Comanche counties in south central Kansas.
Cooler and drier air will continue to filter into the area today within northerly flow in the wake of last night's cold frontal passage. /TW/ Today and Tonight: Cooler and dry through the period. Early morning surface analysis had a dry cold front nearly along the Natchez Trace that will continue to move south through the remainder of the CWA this morning. Surface analysis also had a >1020mb high centered over the central Plains that will be aided by a deepening upper level trough over the region in bringing in cooler and drier air to our CWA. Guidance has come in a little cooler for lows Tuesday morning and our normally colder locations may bottom out in the upper 40s. Most sites wl see the lower 50s.
Mid-level water vapor imagery this afternoon shows northwesterly flow over the central Plains with broad ridging over the western US. With these conditions, temperatures across the area have climbed into the low to mid 70s and should only increase a few more degrees this afternoon. The upper-level trough will move off to the east by Tuesday with weak ridging building in by the middle of the week.
146 PM PDT Mon Sep 26 2022 Drier and warmer conditions are expected for today and Tuesday, followed by a gradual cooling trend.
1205 PM CDT Mon Sep 26 2022 (Today and tonight) Cold front had pushed south of West Central Texas early this morning, and the showers and thunderstorms that developed along and behind it, were moving south of the I-10 corridor at 3 AM CDT. High temperatures will be slightly cooler, in the upper 80s to 90 degree range.
A well defined marine layer will support summerlike conditions with the coast remaining cooler and cloudier into Tuesday. A slight warming trend is then expected late in the week as high pressure builds back over the region before temperatures return to near normal this upcoming weekend. An approaching mid/upper level trough on Tuesday will support slight deepening of the marine layer overnight with the potential for coastal drizzle by Tuesday morning.
1140 AM MDT Mon Sep 26 2022 High pressure centered over the Central Rockies will be shifting slowly eastward over the next 24 hours. As the ridge axis jumps to the east side of the Divide, moisture pooling to the south will gradually lift back north, sweeping through the Four Corners this afternoon and evening. Ground penetrating rainfall potential looks meager over the next 36 hours, but there could be a few cells that drop locally wetting rains over the higher peaks.
Near the surface, a broad area of high pressure is sliding southeast out of the Dakotas into the Central Plains. Upper level ridging over the Rockies and high plains will lead to warmer temperatures today along with light winds becoming southerly at 10 mph. Highs will generally be in the lower to mid 80s. Temperatures tonight will fall back into the low to mid 50s given the dry air in place and relatively light winds. Upper level ridging will prevail over the Rockies through mid week. An upper level trough will move southeastward out of Canada into the upper Midwest by Tuesday, pushing a weak cold front through western Kansas. Ahead of the front, high temperatures will warm into the mid 80s to lower 90s Tuesday, with the warmer readings in Barber and Comanche counties in south central Kansas.
(Tonight through Tuesday night) Latest surface analysis shows the cold front spanning SW to NE across the northern portion of the CWA with dewpoints dropping into the low 60s in Cotulla. Dry and mostly clear skies will lead to cooler nights through the week with tonight's lows reaching the mid 60s over the Coastal Plains.
(Tonight through Tuesday night) A weak cold front continues to move southward and is expected to pass through Deep South Texas and the Rio Grande Valley overnight tonight into Tuesday. Moisture convergence ahead of the front will continue to bring isolated to scattered showers and thunderstorms to the area, with models continuing to indicate the greatest chances for precip across the lower Valley through Monday morning. The cold front will not do to much in regards to lowering daytime temperatures on Tuesday, maybe a few degrees, but much drier air in wake of its passage will make it feel much more comfortable especially as we head into Tuesday night. Tuesday night will be when we notice some cooler air with lows falling generally into the low to mid 60s. Minor coastal flooding is possible during the high tide cycles on Tuesday.
842 AM PDT Mon Sep 26 2022 Drier and warmer conditions are expected for today and Tuesday, followed by a gradual cooling trend.
236 PM MDT Mon Sep 26 2022 High pressure aloft will dominate the weather pattern for the next few days with very warm afternoons expected. Sunny skies again Tuesday with highs in the lower to mid 80s. The pressure gradient will be tightening in the southeast zones in response to a short wave rounding the upper ridge through southern Canada.
Skies will be mostly cloudy based on moisture in the low levels and expected cumulus cloud development. Have gone a tad bit warmer for highs on Tuesday.
1225 PM CDT Mon Sep 26 2022 (Today through Tuesday Night) Latest surface observations at the time of forecast (3 AM CDT) indicate the continued progression of a weak surface cold front through SE TX, roughly extending along a Caldwell-Crockett-Lufkin line.
Amplified longwave trough will remain positioned over the the East CONUS with the upstream branch of the upper jet translating through the Great Lakes and the Ohio Valley. Simultaneously, strong high pressure descending from the Canadian Prairies will reinforce the cold and dry air advection during the next couple of days as the tight pressure slowly relaxes. Expect temperatures and dewpoints to be few degrees lower than today with Monday night lows in the low to mid 40s and Tuesday highs around 70 degrees.
dry conditions continue, with cooler than average temperatures continuing.
1214 PM CDT Mon Sep 26 2022 (Now through Tuesday) A cold front is approaching Deep South Texas, although, the only real relief it may bring would be drier air. Expect the mid- level ridge to strengthen back across Texas into Tuesday as Ian works into the Eastern Gulf of Mexico, bringing an end to the chance of rain locally. Temperatures will remain warm Monday and Tuesday, potentially a degree or two cooler based on cloud cover and any persistent rainfall.
Low temps will be even cooler across parts of the higher of the Trans Pecos. Tue the surface thermal ridge will be tied to the lower elevations just e of the Caprock and in general highs of 85-90 will be the rule, except warmer Rio Grande and cooler in the mtns.
1211 PM CDT Mon Sep 26 2022 Cooler and drier air will continue to filter into the area today within northerly flow in the wake of last night's cold frontal passage. /TW/ Today and Tonight: Cooler and dry through the period. Early morning surface analysis had a dry cold front nearly along the Natchez Trace that will continue to move south through the remainder of the CWA this morning. Surface analysis also had a >1020mb high centered over the central Plains that will be aided by a deepening upper level trough over the region in bringing in cooler and drier air to our CWA. Guidance has come in a little cooler for lows Tuesday morning and our normally colder locations may bottom out in the upper 40s. Most sites wl see the lower 50s.
133 PM EDT Mon Sep 26 2022 An upper level trough over the Northeast U.
Upper level troughing still situated over the Eastern United States today, with low pressure centered over the Great Lakes region. High pressure over the Central Plains and Middle MS Valley moves east towards us this evening and into Tuesday. Dewpoints dip through the late afternoon and early evening today as dry air aloft is able to mix down to the lower levels, which leads to low RH values across the area. Dry and seasonally cooler temperatures are expected mid-week, followed by a warming trend towards the weekend.
1222 PM CDT Mon Sep 26 2022 (The rest of today ) Post frontal surface ridging and dry air in place lead to some pretty chilly lows this morning across the region. Surface ridging will remain over the area today leading to abundant sunshine and relatively light winds.
214 PM MDT Mon Sep 26 2022 A broad ridge of high pressure over the Intermountain West will continue to dominate the weather pattern through the short term period. A weak disturbance will move across southern Alberta on Tuesday as the ridge axis slowly shifts east over the eastern Rockies by late Tuesday. The longwave pattern transitions by mid-week as a Pacific storm impacts the Pacific Northwest region and a flattening ridge of high pressure pushes east of the Rockies.
1200 PM CDT Mon Sep 26 2022 (Today through Tuesday) A cold front has entered the northern part of our CWA and is stretched from near Georgetown to Rocksprings to western Val Verde County. Today's high temperatures will be cooler across the north where the front will pass early in the day and remain well above normal across the south.
Expect quiet and dry conditions with a bit of steam fog around daybreak along area waterways will be the rule through the first part of the workweek as a large upper ridge builds over western US. However high pressure building southward through the upper midwest will start push a weak backdoor front into eastern Nebraska and result in temperatures at to slightly below normal up near the Niobrara valley where readings will be in the lower 70s.
The cold front that pushed across the area yesterday is now well to the S of the local CWFA, draped E to W across the FL Panhandle and snaking SWW back along the Texas Gulf Coast.
A back-door cold front slides in Tuesday morning, leading to a wind shift out of the east as well as cooler temperatures due to CAA through the day on Tuesday, with highs in the low 60s to low 70s across the CWA (+/- 5 degrees from climatology).
1148 AM CDT Mon Sep 26 2022 A mid/upper trough was situated across the Great Lakes area while northwest mid/upper flow prevailed upstream across the Central Plains. This larger-scale pattern will remain in place early in the week and as we move into the middle of the week we'll see a greater influence from the mid/upper ridge axis building over the Southern Plains.
(This evening through Tuesday) With the cold front well south of our area, we have a much drier and slightly cooler airmass in place over West Central Texas. Combined with the dry air in place, this will create prime radiational cooling conditions - meaning lows will be on the cooler side in the mid to upper 50s with drainage spots and low lying areas potentially dropping even further. The large upper trough across the eastern CONUS will continue to drift east. In response, the upper ridge across the western CONUS will also slide east with the upper high reasserting itself over the Four Corners region and Texas. As such, daytime highs tomorrow will be a touch warmer than today in the upper 80s to low 90s.
