(Tonight through Wednesday night) The short term period will feature near normal temperatures and generally rain-free conditions across Deep South Texas as high pressure continues to influence the region. High temperatures will be near seasonal normals for mid July with highs ranging from the mid 80s along the Lower Texas beaches to mid 90s further inland.
After the passage of a cold front on Wednesday, drier and cooler conditions will move into the region. The chance of storms will persist until a cold front crosses the CWA. High temperatures Wednesday are expected to be in the lower to mid 80s, with low temperatures ranging from the upper 50s north to lower 60s south.
For this evening, expect cooler and quieter weather with persistent northwest flow once the system passes to the east. This northwest flow will allow temperatures to drop into the upper 40s to low 50s area wide, the exception being near the immediate lakeshore where temperatures will remain in the middle to upper 50s due to a warmer lake this time of year. Wednesday will definitely feel cooler compared to what we have experienced recently with temperatures hovering right around 70 degrees for most locations. Speaking of weather for once there is not too much to talk about, which for our area is a good thing! High pressure will dominate overhead for the next several days resulting in plentiful, abundant sunshine.
as a cold front will slowly cross the Lower Great Lakes.
There is a couple of broken lines of convection that remain active off the Lower Keys. An Atlantic ridge continues to extends it reach across the Florida Peninsula and over the Gulf of Mexico.
1244 PM CDT Tue Jul 16 2024 - A cooler but still hot day today with afternoon/evening showers and thunderstorms - Unseasonable cool temperatures expected for mid week and through the weekend. Central Kansas will be as much as 14-16 degrees cooler today. Cloud cover and cooler air will continue to push into the region through the afternoon. Areas of far Southeast Kansas are the most likely areas to see the higher heat indices. The extended range indicates a series of Canadian high pressure systems pushing into the region.
Upper level troughing will present to our north, while we remain entrenched in tropical moisture.
Tonight and Wednesday: The upper level ridge has shifted slightly east allowing warm southwest flow to intrude over the Inland Northwest.
Current mid-level water vapor imagery shows a plume of moisture rounding the ridge aloft, pushing into Colorado this afternoon. Wednesday, the upper level ridge centers over the Four Corners region with Colorado on the eastern periphery in northerly flow aloft. Temperatures are expected to be cooler with highs in the low to mid 80s across the I-25 corridor and plains.
631 PM CDT Tue Jul 16 2024 - Pleasant weather ahead! A cooler, less humid, and drier forecast through the rest of the week. Satellite imagery and RAP progs show an upper level trough which is forecast to move down across the Great Lakes into Wednesday, with a wave currently moving across the region. An amplified upper level pattern will remain as a strong ridge holds across the western U. and a trough over the east-central U. At the surface Canadian high pressure looks to dominate over the region bringing cooler conditions and less humid air.
After the passage of a cold front on Wednesday, drier and cooler conditions will move into the region. A surface cold front across the Southern Great Lakes slips a little south into ILN/s far northern counties toward sunrise. On the warm side of the front - expect mild lows generally in the lower 70s. The chance of storms will persist until a cold front crosses the CWA. High temperatures Wednesday are expected to be in the lower to mid 80s, with low temperatures ranging from the upper 50s north to lower 60s south.
1027 PM EDT Tue Jul 16 2024 Shower and thunderstorm chances increase during the mid-week period as a trough sets up over the eastern US and a cold front approaches from the northwest.
538 PM EDT Tue Jul 16 2024 Shower and thunderstorm chances increase during the mid-week period as a trough sets up over the eastern US and a cold front approaches from the northwest.
745 PM MDT Tue Jul 16 2024 Warm and mostly dry weather continues for the foreseeable future as upper level ridging remains parked over the area. Although upper level ridging is present across the region, enough instability has been around near the Idaho border to result in a few showers and thunderstorms early this evening.
As is typical with the location of the ridge axis the convection near and to the north of the axis has shifted east to the eastern side of the Florida peninsula this evening while to the south of the axis the convection is continuing to drift west northwest, but will weaken and dissipate as the evening progresses. Low level high pressure ridge will continue to stretch east to west across the central Florida peninsula through the work week.
While apparent temperature guidance is near or slightly above the threshold in a few more locations due to the higher dewpoints, should the more widespread convection verify as expected, only the areas that remain largely precip and cloud free would be at risk of remaining above criteria for any significant length of time.
942 PM CDT Tue Jul 16 2024 - Cooler and drier air will continue to spread across the area through mid week. We are looking at a dry period of weather tonight through Wednesday night as lower dew point air works south across the area due to high pressure building over the northern Plains and Upper Midwest. Lows will be down into the 60s tonight, with cooler 50s Wednesday night. The aforementioned high pressure system will continue southeast through the end of the work week, with temperatures a bit below average and dry weather continuing. The overall pattern will be one where a strong upper level ridge will be set up over the Four Corners region, with a persistent upper trof over the eastern CONUS.
This afternoon a fairly robust short wave is moving up the west side of the ridge and into northwest CA. This will bring cooler temperatures to the inland areas and will reinforce the onshore flow keeping the coastal clouds in place.
Ridging across the Florida Peninsula will continue to promote moderate east to southeast winds across our CWA. From synopsis, Atlantic ridging will remain across the Florida Peninsula through the duration of the forecast.
636 PM CDT Tue Jul 16 2024 Expect rain chances to increase tonight as a cold front approaches the Mid-South.
- A cold front will push through on Wednesday with another round of strong to severe thunderstorms.
Warm and mostly dry weather continues for the foreseeable future as upper level ridging remains parked over the area.
Issued 942 PM CDT Tue Jul 16 2024 Quiet weather conditions expected tonight into early Wednesday as northwest winds gradually deliver and cooler and drier airmass. Into Wednesday, with the upper trough located across SE Canada through the Great Lakes region will slide some PVA through the region but given the midlevel dry air through the region that forcing will struggle to produce much in the way of precip on its own.
As storms soon enter into the Mid-South along a slow moving cold front, primary threats will be damaging winds and localized heavy rainfall in areas mainly north of I-40. Expect rain chances to increase tonight as a cold front approaches the Mid-South.
Convection associated with an upper trough centered near the coast extends into southern Oregon this evening. Models continue to support a 15-30 percent chance of showers/thunderstorms along the trough axis as it moves across SE Oregon tonight and SW Idaho on Wednesday. High temperatures look to be on par with today's reading of around 100 degrees in the lower valleys.
620 PM CDT Tue Jul 16 2024 - Cooler and drier air will continue to spread across the area through mid week. We are looking at a dry period of weather tonight through Wednesday night as lower dew point air works south across the area due to high pressure building over the northern Plains and Upper Midwest. Lows will be down into the 60s tonight, with cooler 50s Wednesday night. The aforementioned high pressure system will continue southeast through the end of the work week, with temperatures a bit below average and dry weather continuing. The overall pattern will be one where a strong upper level ridge will be set up over the Four Corners region, with a persistent upper trof over the eastern CONUS.
643 PM CDT Tue Jul 16 2024 - Few early shower/thunderstorm chances this evening - Bit cooler and less humid Wednesday.
629 PM CDT Tue Jul 16 2024 (Tonight through Wednesday night) The short term period will feature near normal temperatures and generally rain-free conditions across Deep South Texas as high pressure continues to influence the region. High temperatures will be near seasonal normals for mid July with highs ranging from the mid 80s along the Lower Texas beaches to mid 90s further inland.
1257 AM CDT Wed Jul 17 2024 (This evening through Thursday) The overall synoptic pattern had Arkansas was on the eastern edge of an upper ridge this morning. The ridge is retrograding and amplifying over the western US, which will result in a trof taking its place over the midsection of the country. A cold front will be moving out of the Plains and making its way into Arkansas tomorrow. Thunderstorm chances will increase across the state tomorrow, reaching the highest POPs tomorrow night.
Heat will be the primary weather story through the weekend as a large high pressure center moves overhead. High pressure center currently settled across western New Mexico will expand westward over the coming days with a slightly strengthening southerly steering flow developing over the region. Unlike a couple weeks ago, this high pressure center is no longer extremely dry and instead has fairly considerable moisture trapped beneath it.
309 AM EDT Wed Jul 17 2024 * Periodic showers and storm continue through today, with a northwest to southeast drying trend expected tonight behind a cold front.
After the passage of a cold front on Wednesday, drier and cooler conditions will move into the region. A surface cold front across the Southern Great Lakes slips a little south into ILN/s far northern counties toward sunrise. On the warm side of the front - expect mild lows generally in the lower 70s. The chance of storms will persist until a cold front crosses the CWA. High temperatures Wednesday are expected to be in the lower to mid 80s, with low temperatures ranging from the upper 50s north to lower 60s south. A mid level trough axis will be digging east through the remainder of the Great Lakes, southeast Canada, and New England on Thursday.
The southwest is expected to reach the low to mid 80s Wednesday. A few readings in the lower 90s are possible in the southwest Thursday.
220 AM CDT Wed Jul 17 2024 - Cooler and drier air continues to spread across the area. Highs today, should climb to the upper 70s north to the lower 80s central and south. This evening looks to be outstanding as winds decrease under 10 mph, and temperatures hold in the lower 70s through sunset.
1237 AM CDT Wed Jul 17 2024 (Tonight through Wednesday night) The short term period will feature near normal temperatures and generally rain-free conditions across Deep South Texas as high pressure continues to influence the region. High temperatures will be near seasonal normals for mid July with highs ranging from the mid 80s along the Lower Texas beaches to mid 90s further inland.
- Pleasant weather with low humidity, cooler-than-normal temperatures and no rain chances tonight into the first half of the weekend. Issued 338 AM CDT Wed Jul 17 2024 Today through Thursday: An upper trough sliding across Ontario and Lake Superior continues to drive our weather for now. We should see clearing skies tonight but that upper trough will still be slowly exiting, so a few mid level clouds are probable.
As ridging over the Desert Southwest translates west, mid-level disturbances will provide instability and forcing to increase rain chances further.
304 PM EDT Tue Aug 19 2025 * Cold front approaches from the west, but stalls briefly over western PA before moving through Central PA on Wed. * High pressure over eastern Canada will help keep Erin offshore and PA dry as the hurricane passes our latitude. SHRA/TSRA will move in from the NW, but likely not get into the Lower Susq by morning. The low clouds should re-establish themselves tonight, and may lead to a patch or two of DZ, but likely not enough to paint in the grids. Cold front gets to the OH/PA border by sunrise.
Otherwise, the main impact today will again be the high heat indices through the afternoon and early evening.
(This evening through Wednesday) A quasi-stationary pattern remains in place over much of the western CONUS with upper level ridging centered near the Four Corners with the forecast area on the southeastern flank of the upper high. This leaves us with diurnally driven afternoon convection fired mainly by reaching convective temperature with some organization possible on outflow boundaries to begin with and the potential for additional development and possibly organization should the central High Plains short wave trough rotate to the southwest.
206 PM EDT Tue Aug 19 2025 An area of low pressure and cold front will approach and cross the region tonight and Wednesday, with widespread showers and a few thunderstorms. Dry weather will return late in the week as high pressure builds into the region. Better overall organization of the surface wave will strengthen the low level jet and warm advective pattern into the region. Cold front slides through the region late tonight and Wednesday morning. A few stray showers still possible Wednesday night across the Southern Tier, but the inbound cooler and less humid air mass should get rid of the precipitation threat overnight.
High pressure will continue to dominate the weather across southwest Kansas, suppressing storm chances.
113 PM EDT Tue Aug 19 2025 Showers and thunderstorms are possible late this afternoon into the evening ahead of a cold front. Drier and cooler conditions arrive behind the front for Wednesday.
- Drying trend in place Wednesday through the balance of the week with slightly cooler temperatures.
113 PM EDT Tue Aug 19 2025 High pressure will maintain dry weather today. Scattered shower and thunderstorm chances will return tonight and Wednesday with a weak cold front.
Meanwhile, temperatures along the island chain are already near 90 with unfortunate dewpoints up to the lower 80s.
1243 PM CDT Tue Aug 19 2025 Upper ridging remains in control of the forecast across the region maintaining deep layer northerly flow over the forecast area. As upper ridging slowly retrogrades westward by the end of the week, temperatures gradually cool to near normal featuring highs in the upper 80's to lower 90's. Overnight lows generally stay in the lower to middle 70's through the end of the week. Isolated to scattered showers and storms can be expected each day, increasing in coverage late week into the weekend thanks to the upper ridge shifting away from the area.
- Showers and thunderstorms will increase through this evening and continue into Wednesday as a cold front moves into the region. - Temperatures will trend cooler behind the front through the end of the week.
145 PM EDT Tue Aug 19 2025 Clouds will thicken this evening ahead of an upper level disturbance and a low pressure system approaching from the lower Great Lakes and Ohio.
Take care to avoid causing a spark! - Cold front Wednesday night will bring cooler temperatures (75-85 degree highs) through the weekend, but precipitation chances remain low. Ridge aloft amplifies tonight over the area, producing the warmest night of the forecast period, lows in the 60s to lower 70s central and east. Some areas east of Billings could cool off a bit in the evening only to have temperatures rise (possibly substantially) overnight as these winds mix in warmer air from aloft.
High pressure will bring warm and mostly dry conditions to the region through Wednesday.
629 PM CDT Tue Aug 19 2025 - A weak upper level ridge aloft and northerly flow will bring about hot and humid conditions through Wednesday with late in the afternoon thunderstorms which may bring locally heavy rainfall and gusty winds.
631 PM EDT Tue Aug 19 2025 Scattered shower and thunderstorm chances will return tonight and Wednesday with a weak cold front. KEY MESSAGES: - Cold front brings scattered showers and storms tonight - Mild overnight lows --------------------------------------------------------------- Ongoing broken clusters of showers and storms are progressing across central Ohio this evening along an eastward moving cold front.
845 PM CDT Tue Aug 19 2025 The northeast to southwest moving cold front has started moving across the Panhandles with observed wind gusts upwards of 45 mph across the northeastern TX Panhandle and the eastern OK Panhandle. (This evening through Wednesday night) Upper level high pressure continues to dominate from the Four Corners Region to the Panhandles. Another day of warm temperatures in the lower to mid 90s is expected this afternoon with a slight chance for some isolated summer convection. Tonight under mainly northerly flow aloft on the western periphery of the upper high some subtle perturbations may spark some additional convection.
A persistent ridging pattern will lead to a warming and drying trend across the region through the forecast period. A rather weak trough will pass through the region tonight into Wednesday leading to some locally breezy westerly winds with gusts to around 25 mph. By Wednesday night, the system pushes eastward, then ridging is anticipated to build and strengthen across the Inland Northwest for the remainder of the 7-day forecast.
1046 PM EDT Tue Aug 19 2025 * Cold front approaches from the west, but stalls briefly over western PA before moving through Central PA on Wed. * High pressure over eastern Canada will help keep Erin offshore and PA dry as the hurricane passes our latitude. SHRA/TSRA will move in from the NW, but likely not get into the Lower Susq by morning. The low clouds should re-establish themselves tonight, and may lead to a patch or two of DZ, but likely not enough to paint in the grids. Cold front gets to the OH/PA border by sunrise.
623 PM CDT Tue Aug 19 2025 - Cooler and drier weather is forecast for the rest of this week and through this weekend. A long-awaited cold front is currently pushing south through the southern CWA. This discontinuity is due to a lag between the front and the cooler air it's ushering in. Very low shear paired with the high SBCAPE has allowed for pulse convection yet again this afternoon. The lag of the cooler airmass will be obvious tonight as low temperatures only drop into the upper 60s to low-70 - not much cooler than last night. The push of cooler air is due to arrive tomorrow morning, and this is when we'll finally feel the difference. 850 mb temperatures will quickly fall from the low-20s into the mid to upper teens.
723 PM EDT Tue Aug 19 2025 Scattered shower and thunderstorm chances will return tonight and Wednesday with a weak cold front. KEY MESSAGES: - Cold front brings scattered showers and storms tonight - Mild overnight lows --------------------------------------------------------------- Ongoing broken clusters of showers and storms are progressing across central Ohio this evening along an eastward moving cold front.
1057 PM EDT Tue Aug 19 2025 * Cold front approaches from the west, but stalls briefly over western PA before moving through Central PA on Wed. * High pressure over eastern Canada will help keep Erin offshore and PA dry as the hurricane passes our latitude. The clouds will likely intersect the higher terrain of the Laurel Highlands and may reduce visibility to 1/2 mile or less on the ridgetops into the morning. Low temperatures tonight will range from the upper 60s over the northern tier to the mid 60s in the Lower Susquehanna Valley. Showers and a few thunderstorms ahead of an approaching cold front are beginning to enter northwest PA and will continue to move in through the rest of the night.
A cold front pushes through Wednesday and Wednesday night. Much stronger cold front arrives for the weekend, dropping temperatures significantly. After a hot and fairly humid day today, a cold front currently to our west and northwest will approach the area tonight.
750 PM EDT Tue Aug 19 2025 Showers and thunderstorms are possible late this afternoon into the evening ahead of a cold front. Drier and cooler conditions arrive behind the front for Wednesday.
500 AM EDT Wed Aug 20 2025 Scattered shower and thunderstorm chances can be expected with the passage of a weak cold front today. KEY MESSAGES: - Cold front and associated upper trough brings scattered showers/storms this morning and afternoon.
- An approaching cold front will provide temporary relief through the end of the week, but will increase storm chances in the immediate short term. This is around 5 deg F warmer when compared to last night at this time. Wednesday should start on the quiet side, though temperatures will quickly rebound ahead of the southward advancing cold front.
- Showers and thunderstorms will continue on Wednesday as a cold front moves through the region. - Temperatures will trend cooler behind the front through the end of the week.
(Through Wednesday) Storms continue to shift southward, leaving a slightly cooler airmass in their wake. Wednesday will be slightly cooler across most of the area (highs in the mid 90s).
Upper ridging remains in control of the forecast across the region for one more day maintaining deep layer northerly flow over the forecast area. Upper troughing slowly shifts into the area while upper ridging retrogrades westward late week into the weekend, helping to slowly cool temperatures down and increasing rain chances.
155 AM EDT Wed Aug 20 2025 A wave of low pressure tracks across southern New England today bringing chances for light rain, mainly across southernmost NH and far SW Maine.
Take care to avoid causing a spark! - Cold front Wednesday night will bring cooler temperatures (75-85 degrees) through the weekend, but precipitation chances remain low.
137 AM EDT Wed Aug 20 2025 * Cold front approaches from the west, but stalls briefly over western PA before moving through Central PA on Wed. * High pressure over eastern Canada will help keep Erin offshore and PA dry as the hurricane passes our latitude. The clouds will likely intersect the higher terrain of the Laurel Highlands and may reduce visibility to 1/2 mile or less on the ridgetops into the morning. Low temperatures tonight will range from the upper 60s over the northern tier to the mid 60s in the Lower Susquehanna Valley. Showers and a few thunderstorms ahead of an approaching cold front are beginning to enter northwest PA and will continue to move in through the rest of the night.
Highs in the lower to middle 90s, although dew points decrease during the day due to turbulent mixing, so heat indices should be manageable.
130 AM MDT Wed Aug 20 2025 - Wednesday will see near record high temperatures as high pressure continues, with some locations east of the Continental Divide hitting 100 degrees.
Isolated to scattered showers and thunderstorms will be possible with the highest rain chances over the interior and eastern half of the Florida peninsula.
154 AM EDT Wed Aug 20 2025 Scattered shower and thunderstorm chances will return tonight and Wednesday with a weak cold front. KEY MESSAGES: - Cold front brings scattered showers and storms tonight - Mild overnight lows --------------------------------------------------------------- Ongoing broken clusters of showers and storms are progressing across central Ohio this evening along an eastward moving cold front.
The morning will likely start out mostly cloudy with a few patches of fog around, but overall should be a more comfortable "feel" than the past few days a dew points begin to fall off this afternoon and highs only look to reach into the low and mid 80s for most. Will likely still hold onto some values around 90 across our S, but overall notably cooler/less humid than yesterday.
