416 AM CDT Wed May 25 2022 An upper level trough located over the nation's mid-section continues to dig and is forecast to close off over eastern Kansas by late in the day. Meanwhile, upper heights will begin to build east into the region on Thursday as ridging builds east across the Rockies.
Much cooler weather returns Thursday, and shower chances return to the mountains and northern Sacramento Valley over the weekend. Strong upper ridge is currently moving overhead and skies are clear across the region.
633 AM CDT Wed May 25 2022 Drier north-northwest flow today following upper low that was moving east across Oklahoma. /issued 300 AM CDT Wed May 25 2022/ Upper level low pressure over northwest Oklahoma early this morning will continue to the east moving into eastern Oklahoma and eastern Kansas later today. Clouds will tend to decrease and maximum temperatures today will warm mostly to the lower to mid 70s, or around 15 degrees below normal for late May.
An upper level trough located over the nation's mid-section continues to dig and is forecast to close off over eastern Kansas by late in the day. Meanwhile, upper heights will begin to build east into the region on Thursday as ridging builds east across the Rockies.
639 AM CDT Wed May 25 2022 Overall upper level scenario features a trough over the central United States with a closed low over the south central Plains near the base of the synoptic trough. Today will be rather cool thanks to the influence of the nearby upper closed low. More rain chances will continue for today into tonight as the low slowly nudges east. Rain chances will continue to decrease as the low continues to move east. Based on latest model spreads, a combo of NBM and Conshort seemed appropriate for highs Thursday in the 70s (cooler temps to the east).
440 AM MDT Wed May 25 2022 Current surface map places low across eastern Kansas with weak high pressure across the Dakotas. Scattered showers associated with Central Plains upper low remain south and east of the forecast area. Upper level ridge builds across the Northern Plains today and Thursday with mid level subsidence and drying low levels.
/NEW/ /Through Thursday/ Precipitation has mostly ended across the region, the exception being along the Red River where some wrap-around showers are occurring on the southern flank of an upper low. The low will continue to move east, taking the rest of the moisture and precipitation with it later today.
As clouds are rotating around building high pressure, a few sprinkles or light rain may develop around daybreak from Missoula to Kalispell.
(Today and tonight) The pesky upper low will move slowly over the area today and tonight with areas of showers again before moving east of the area late tonight. This area of showers will eventually pivot east today, with another area of showers developing in the north close to the mid-level cyclone with some wrap-around precipitation also expected west of the cyclone. All of this will shift eastward tonight as the cyclone moves east.
High pressure remains anchored offshore of the SE US, providing SE-ESE winds over ECFL. Overnight lows are expected to be in the low to mid 70s except upper 60s possible in the traditionally cooler locations.
619 AM EDT Wed May 25 2022 High pressure will remain in place east of New England through midweek.
504 AM MDT Wed May 25 2022 An upper ridge will be building into the region through the end of the week, for warmer temperatures and generally dry weather. High pressure will move from the northern Rockies into the Dakotas on Thursday with another bump up in temperatures.
339 AM MDT Wed May 25 2022 The remaining clouds are slowly dissipating as the trough moves eastward away from Colorado. With the clearing, there will likely be a few patches of fog in some of the colder spots which will also be just a little above freezing.
(This evening through Thursday) Quiet and pleasant weather through Thursday behind the cold front that caused our thunderstorms last night. Lows tonight will again be cooler than normal, dropping into the low to mid 50s in most areas. For Thursday, temperatures will rebound quickly from the cooler readings today, warming up into the upper 80s to mid 90s under mostly sunny skies.
359 PM CDT Wed May 25 2022 Unsettled weather pattern for the next couple of days as an upper low tracks just north of the Mid-South.
While cloud cover will linger across eastern SD tonight as a large storm system moves slowly northeast, high pressure will lead to mostly sunny skies across the area by Thursday late morning. Generally quiet weather continues into Thursday night as a ridge of high pressure aloft remains in place.
308 PM EDT Wed May 25 2022 High pressure off of the New England coast will maintain fair weather over Pennsylvania tonight.
Warmer weather returns to the area beginning Thursday. Showers and thunderstorms also increase by Thursday evening ahead of a cold front.
250 PM MDT Wed May 25 2022 A high pressure ridge is moving in from the west bringing strong subsidence aloft and the clear sunny skies we see today. Look for temperatures to warm ten degrees tomorrow under the ridge with light to breezy afternoon winds. The overnight lows tonight will still cool to freezing in some of the higher valleys, so ytou'll want to cover your gardens tonight.
The marginal risk, of rainfall over flash flood guidance, continues into the evening, as the moisture with the warm front continues to stream up from the Gulf of Mexico more rain will break up, especially along the 500 mb jet that is oriented roughly S to N, along Lake Michigan and NW Lower, and crossing E Upper.
243 PM CDT Wed May 25 2022 Satellite imagery continues to show the upper closed low spin over portions of the central/southern Plains. As the main upper level system continues east into the Ohio Valley, upper ridging will move overhead for the weekend.
Highs will remain in the mid 70's across the northern Midlands and Pee Dee, and into the low-mid 80's south of the front in the CSRA. Upper ridge offshore moves east in response to mature cyclone/closed low moving from the Mid Mississippi Valley toward the Ohio Valley. A trailing cold front will be approaching from the Gulf coast region late.
Scattered showers and storms are already showing up on radar beyond 60 nm in response to increased tropical moisture and southerly winds in advance of the area of low pressure and frontal boundary over the central U.
(This afternoon through Thursday Night) Dreary weather pattern will continue over the next 36 hours as an upper-level trough slowly crosses the area. With the warm front well to our north, our area is receiving plenty of low- level moisture coming from the Gulf.
Once this activity exits the region early this evening, timing of additional rounds of showers and storms is still hard to pin down at this time as the upper level low slowly makes its way through the forecast area.
225 PM MDT Wed May 25 2022 The CWA was sandwiched between a upper low over the east-central Great Plains and upper ridge over the Intermountain West. Some high clouds were passing across northern WY, with scattered diurnal cumulus clouds over the higher terrain and NE Panhandle. Temperatures were 5 to 10 degrees warmer than 24 hours ago. Looking at a fairly benign short term weather-wise with ridging at the surface and aloft the dominant feature.
Still no clear signal upstream that organized convection will be initiated this afternoon as warm advection is rather broad with no clearly defined warm front to focus on.
Water vapor loop has split flow aloft with the main southern upper low remaining well to our south. We do know that return to SW flow downstream of Rockies trough axis will foster moisture advection and attendant instability, but what we can't be certain of at this time is the strength/magnitude of these critical parameters. The long wave trough has a reasonable chance to stay west of the forecast area through Tue, keeping shower and isolated thunder chances alive, then it heads east, increasing chances for drier, but unseasonably cool weather for Wed.
Upper air and satellite imagery showed upper level low pressure centered over north central Oklahoma today. Vorticity lobes rotating around the northern quadrant of upper low were generating areas of light rain and showers across central Kansas, generally along and east of Highway 283. Latest model guidance moves the upper low east to the KS/MO border by Thursday morning.
Mid/upper level pattern currently features broad ridging building in across Arizona with clear skies and above normal temperatures.
(Tonight) Slow moving upper low currently across northern OK will wobble east-northeast overnight, eventually moving into southeast KS/southwest MO by Thursday morning. Expect mainly scattered showers across far eastern OK into northwest AR into the early evening (an isolated rumble of thunder may occur), with more widespread light showers working into northeast OK overnight as the low pulls away. (Thursday through Wednesday) The upper low will track into eastern MO later Thursday, with any lingering showers tapering off late in the day.
115 PM MST Wed May 25 2022 High pressure will build over the region over the next couple days leading to a warming trend and lower desert high temperatures above 100 degrees today.
With a warm front to the north showers and thunderstorms will begin to fill in and become more numerous from south to north across middle TN.
242 PM CDT Wed May 25 2022 Key Messages: - More Showers Tonight, Exiting East Thu - Rain/Storm Chances for Holiday Weekend * SHOWERS TONIGHT, PUSHING EAST THU The morning swath of showers continues to push northward as the low level warm air advection (main driver) shifts across the northern great lakes.
Meteorological Analysis: The pesky upper low, currently sitting over northern Oklahoma will continue to slowly meander eastward through the night into tomorrow. As the upper low departs, we should see some clearing of skies from the west bringing us the start of a warming trend. Areas farther east will be slightly cooler under the lingering affects of the upper low (low to mid 70s).
A ridge of high pressure will strengthen over the Northern Rockies tomorrow, allowing for the warmest temperatures of the season thus far.
/Issued 1145 AM CDT Wed May 25 2022/ /Through Thursday/ A pleasant day is unfolding across North and Central Texas in the wake of a late-season cold front. As mid-level ridging builds back in on Thursday, abundant sunshine should result in a warmer day; however, temperatures will still be near to slightly below normal by late-May standards.
The upper level ridge of high pressure will build across Colorado during the day on Thursday with a dry and continued warming airmass. The apex of an upper ridge will push into western Colorado with upper level flow turning more northwesterly.
This afternoon through Thursday night Drier and warmer conditions will be in place across the forecast area today and Thursday. A flat ridge over the Great Basin and Northern Rockies today will allow for high clouds to stream over much of the area through the rest of the morning. The ridge will amplify Thursday, as it moves over the Cowboy State. The ridge will continue to track eastward Thursday night. Weak showers will be possible over western portions, as a cold front approaches.
/NEW/ /Through Thursday/ A pleasant day is unfolding across North and Central Texas in the wake of a late-season cold front. As mid-level ridging builds back in on Thursday, abundant sunshine should result in a warmer day; however, temperatures will still be near to slightly below normal by late-May standards.
Southeast Idaho is under upper level high pressure ridging currently. High pressure ridging is starting to break down and move east with high clouds over our northern areas and winds becoming slightly breezy with gusts of 20 to 25 mph. High pressure ridging shifts east overnight allowing for breezy southwest flow aloft by tomorrow. There is a trough over southern British Columbia expected to impact our area tomorrow afternoon.
255 PM CDT Wed May 25 2022 Large upper trough over the Central to Southern Plains has led to deep layer warm air advection and WV transport into the Mid and Upper Mississippi Valley region today, bringing widespread light to moderate rain. The upper low will shift into southern Missouri on Thursday, bringing additional chances for showers and thunderstorms across eastern Iowa and west-central Illinois, mainly during the afternoon and evening.
(The rest of today ) Upper low continues to churn near central OK with broad precip shield east of its center across eastern OK. Expect widespread light rain to taper off from north to south this afternoon as initial vorticity lobe rotates into KS with more scattered activity lingering especially where brief breaks appear in the low clouds.
We lie on the southwestern periphery of a high pressure centered just off the Carolina coast. In addition, moisture just along the edge of the larger-scale ridge over the eastern U. Ridging over the eastern U. is resisting the approach of an upper level trough that is in the process of cutting off from the main flow over the Southern Plains. 93 inches as noted by this mornings sounding, the lower levels are seeing a plume of relatively drier air pushing in due to the low level ridge to our northeast.
1130 AM EDT Wed May 25 2022 High pressure will remain in place east of New England through midweek.
High pressure will build in tomorrow shunting rain off to the east.
(This afternoon through Thursday night) An upper level trough is over the central part of the country. Temperatures today will be similar or slightly cooler than those yesterday. Upper ridging will begin to build over Southeast New Mexico and West Texas on Thursday.
Tonight through Thursday, the upper low over the central Plains will move east, and end up over southern Missouri by Thursday afternoon. We will continue to see on and off chances of showers and a few thunderstorms moving through with any instances of upper level support rotating around the low.
Temperatures will warm into the low 90s across the Treasure Valley on Thursday, with much of the area seeing values 10 to 15 degrees above normal.
Highs are on track to top out in the lower 50s and we might easily break the record "cold max" in Hastings of 58 degrees set in 1909.
224 PM CDT Wed May 25 2022 Another day of widespread though not intense precipitation today with the upper low still centered in central Oklahoma and minor waves rotating around.
Upper level ridging will move overhead today and the thermal trough will push inland, bringing unseasonably warm temperatures across the region this afternoon. From Thursday onward, we'll see a gradual transition to wetter and much cooler temperatures that will persist through Memorial Day Weekend. An upper trough and surface cold front will approach the coast on Thursday with a chance of showers in the afternoon. Offshore high pressure and a thermal trough near the coast will bring gusty, advisory level north winds and steep seas south of Cape Blanco this afternoon into this evening.
The forecast looks to be in good shape with another beautiful day on tap, just a little warmer than yesterday. Issued at 408 CDT Wed May 25 2022 For today through tonight, upper low pressure sits over the central/southern plains with surrounding ridges over both coasts.
The low pressure system that has been providing the rain for our area today is slowing exiting the region and a high pressure system along with dry weather will move in behind it.
102 PM PDT Wed May 25 2022 Near to above record high temperatures this afternoon will be followed by much cooler temperatures tomorrow into the Holiday weekend.
The low temperatures overnight into early Thursday morning will feel fantastic as they cool down into the upper 50s to low 60s inland and in the mid 60s to low 70s along the coast. For Thursday, sunny skies along with variable winds are expected as high pressure moves across the local area. Another somewhat cool night on tap for Thursday night with lows ranging in the 60s inland and in the low to mid 70s along the coasts.
934 AM MDT Wed May 25 2022 High pressure ridge building into Colorado from the west with moderate northerly flow aloft. Skies are mostly sunny in most locations except lingering low clouds over the high mountain parks which should be mostly dissipated by noon. Another area of clouds is over extreme northeast Colorado under the back side of the upper low. The remaining clouds are slowly dissipating as the trough moves eastward away from Colorado. With the clearing, there will likely be a few patches of fog in some of the colder spots which will also be just a little above freezing.
1237 PM EDT Wed May 25 2022 High pressure remains in control of the area through Thursday.
110 PM MDT Wed May 25 2022 Water vapor shows upper trof axis shifting east from the Plains with upper ridge over the western CONUS. At the surface, lee trof is deepening to our west. Western CONUS ridge will continue to build east, peaking over the Northern Plains by Frridgeiday.
322 PM EDT Wed May 25 2022 High pressure hangs on to keep conditions dry through Thursday, despite on-an-off clouds.
1152 AM EDT Wed May 25 2022 High pressure will remain in place east of New England through midweek.
1124 AM MDT Wed May 25 2022 Current surface map places low across eastern Kansas with weak high pressure across the Dakotas. Scattered showers associated with Central Plains upper low remain south and east of the forecast area. Upper level ridge builds across the Northern Plains today and Thursday with mid level subsidence and drying low levels.
855 AM PDT Wed May 25 2022 Warmer temperatures continue through Thursday.
Upper level ridging will move overhead today and the thermal trough will push inland, bringing unseasonably warm temperatures across the region this afternoon. From Thursday onward, we'll see a gradual transition to wetter and much cooler temperatures that will persist through Memorial Day Weekend. Offshore high pressure and a thermal trough near the coast will bring gusty, advisory level north winds and steep seas south of Cape Blanco this afternoon into this evening.
Overall upper level scenario features a trough over the central United States with a closed low over the south central Plains near the base of the synoptic trough. Today will be rather cool thanks to the influence of the nearby upper closed low. More rain chances will continue for today into tonight as the low slowly nudges east. Rain chances will continue to decrease as the low continues to move east. Based on latest model spreads, a combo of NBM and Conshort seemed appropriate for highs Thursday in the 70s (cooler temps to the east).
243 PM CDT Wed May 25 2022 Today is shaping up to look fairly similar to yesterday, just a bit warmer. Lows tonight will be around normal or slightly above normal for this time of year, in the lower 40s to lower 50s. As the weak trough axis moves through tonight, expect some increasing clouds. Heights will be rising on Thursday as a western upper level ridge nudges closer and deamplifies a bit. This will lead to even warmer temperatures than today, mainly in the 70s, but a few locations over the central part of the state could end up seeing some readings in the lower 80s.
1255 PM CDT Wed May 25 2022 (The rest of today ) Upper low continues to churn near central OK with broad precip shield east of its center across eastern OK. Expect widespread light rain to taper off from north to south this afternoon as initial vorticity lobe rotates into KS with more scattered activity lingering especially where brief breaks appear in the low clouds.
/issued 300 AM CDT Wed May 25 2022/ Upper level low pressure over northwest Oklahoma early this morning will continue to the east moving into eastern Oklahoma and eastern Kansas later today. Clouds will tend to decrease and maximum temperatures today will warm mostly to the lower to mid 70s, or around 15 degrees below normal for late May.
With the low shifting east tonight, cloud cover will decrease across the region and winds will become relatively light as the pressure gradient weakens. Dewpoints in the low to mid 30's should help keep the area out of frost conditions though they may lower enough in far western parts of the area for patchy frost to occur. An upper ridge is forecasted to move into the area which will help begin the transition to warmer and drier conditions.
With the dry air in place for Thursday, temps under sunny skies will jump back about 10 degrees warmer over those today.
524 PM MDT Wed May 25 2022 The CWA was sandwiched between a upper low over the east-central Great Plains and upper ridge over the Intermountain West. Some high clouds were passing across northern WY, with scattered diurnal cumulus clouds over the higher terrain and NE Panhandle. Temperatures were 5 to 10 degrees warmer than 24 hours ago. Looking at a fairly benign short term weather-wise with ridging at the surface and aloft the dominant feature.
317 PM MDT Wed May 25 2022 High pressure moves across the area on Thursday.
Another day of widespread though not intense precipitation today with the upper low still centered in central Oklahoma and minor waves rotating around.
Late season cold front pushed all the way through the forecast area this morning. The mid level trough is still pushing across the area this afternoon and has triggered a few showers around the Victoria Crossroads this afternoon. This could still occur for the next couple of hours, but think most of it is done as the trough is almost past.
Could see the highest coverage in southern Lake County and far western Osceola near the sea breeze collision. (Previous) Mostly dry conditions are expected to persist for one more day as weak high pressure remains to the east of FL.
918 PM EDT Wed May 25 2022 CIMSS mean layer imagery has Key West positioned on the southwestern periphery of a high pressure which is located off the southeastern United States. Nevertheless, a few showers are possible as low level moisture continues to ride along the periphery of the high and winds converge over the area. High pressure off the southeastern United States will drift slowly to the east tomorrow, with winds diminishing during the afternoon.
641 PM CDT Wed May 25 2022 (Tonight) Slow moving upper low currently across northern OK will wobble east-northeast overnight, eventually moving into southeast KS/southwest MO by Thursday morning. Expect mainly scattered showers across far eastern OK into northwest AR into the early evening (an isolated rumble of thunder may occur), with more widespread light showers working into northeast OK overnight as the low pulls away. (Thursday through Wednesday) The upper low will track into eastern MO later Thursday, with any lingering showers tapering off late in the day.
/NEW/ /Tonight and Thursday/ A deep cyclone currently centered over Oklahoma will spend the next 24 hours plodding toward the Mid Mississippi Valley. The southern periphery of the cyclone's cloud shield will sink further south of the Red River this evening, but the precipitation that bled into Northwest Texas this afternoon will contract closer to the core of the system overnight. Skies will clear Thursday as the departing upper low takes its clouds with it.
528 PM MDT Wed May 25 2022 A high pressure ridge is moving in from the west bringing strong subsidence aloft and the clear sunny skies we see today. Look for temperatures to warm ten degrees tomorrow under the ridge with light to breezy afternoon winds. The overnight lows tonight will still cool to freezing in some of the higher valleys, so ytou'll want to cover your gardens tonight.
635 PM CDT Wed May 25 2022 Upper low invof the area through the taf period will make for prevailing mvfr to ifr conditions, especially over northern/ western AR.
Temps were about 2 to 3 degrees cooler than they actually topped out at. Do not believe that the overnight lows are off as the mid level stratus should hold in a little more than originally anticipated which should balance out the lows from dropping the extra degrees as well.
