658 AM EDT Sat Jun 7 2025 (Today through Sunday) High pressure surface and aloft ridging east/west across South Florida will continue through the weekend, acting as a stabilizing factor which is expected to cut down on the coverage of showers and thunderstorms. A narrow plume of Saharan dust trapped in the weak flow around the ridge will persist over South Florida, adding to the stability and drier air in the 850-500 mb layer. Sunday may see a slightly more favorable environment for a couple more showers/thunderstorms due to an upper level trough across the SE U. weakening the ridge ever so slightly.
102 PM CDT Sat Jun 7 2025 - A cold front will bring showers and thunderstorms late this afternoon/evening, highest east of the Missouri River. - Gusty northwest winds of 35-45 mph possible Sunday with cooler temperatures in the upper 60s to low 70s.
Current map shows strong 500hpa low spinning across nrn Sask with lead trough now pushing through western SD. Minor s/w in northwest flow behind trough moving through MT. Main sfc cold front back in MT where strongest 3-hrly pressure rises are located. while not overly impressive ahead of the cold front, are generally in the mid 50s. Feel that gusts may tickle the lower bounds of wind advry critieria in a few places briefly, but see no need to issue any wind headlines for this evening as winds will settle down into breezy category overnight. This seems to line up fairly well with 700hpa theta-e ridging seen in both the GFS & NAM.
155 PM EDT Sat Jun 7 2025 (Today through Sunday) High pressure surface and aloft ridging east/west across South Florida will continue through the weekend, acting as a stabilizing factor which is expected to cut down on the coverage of showers and thunderstorms. A narrow plume of Saharan dust trapped in the weak flow around the ridge will persist over South Florida, adding to the stability and drier air in the 850-500 mb layer. Sunday may see a slightly more favorable environment for a couple more showers/thunderstorms due to an upper level trough across the SE U. weakening the ridge ever so slightly.
1255 PM CDT Sat Jun 7 2025 - Showers and storms are expected today and tonight with a warm front. - Cooler than average temperatures and wrap around showers behind this system. This environment will lead to scattered general thunderstorms throughout the afternoon prior to the arrival of a cold front later this evening.
253 PM EDT Sat Jun 7 2025 * A cold front over Central PA will push south to the Mason/Dixon line by late today.
(Rest of today through Sunday) The northern stream will dip into the southern tier of the CONUS as a large area of low pressure drifts into the Northern Plains. At the surface, a west to east elongated ridge will remain centered in the west-central Atlantic, with its westernmost reach deep into the Gulf.
***UPDATE*** An upper low continues to spin just a few hundred miles west of Central California. Inland areas well away from the coastal influence are showing signs of warming today but most coast and coastal valleys are either trending the same or even slightly cooler than yesterday as the marine layer depth remains steady at just under 3000 feet across the LA Basin and 2000 feet along the Central Coast.
229 PM MDT Sat Jun 7 2025 - A back door cold front Saturday night will bring scattered showers and thunderstorms to our northern zones late Saturday night/Sunday morning, followed by another round Sunday PM near the WY higher terrain.
However, another active day is expected tomorrow as a strong upper level trough will dig into the Upper Midwest forcing a cold front into the area. Out ahead of this front temperatures are expected to rise into the low to mid 80s this will help create a very unstable environment with afternoon MUCAPE values between 3000- 4000J/Kg.
A strong ridge in the mid and upper levels draped across S TX, will result in temperatures being around 5 degrees above normal.
1046 AM MDT Sat Jun 7 2025 - A modest cold front will progress southward through the Tri- State area Sunday morning, stalling over southern Kansas (near the Oklahoma border) during the afternoon. Sunday: A modest cold front will progress southward through the Tri-State area Sunday morning, stalling over southern Kansas (near the Oklahoma border) during the afternoon.
1210 PM EDT Sat Jun 7 2025 * A cold front over Central PA will push south to the Mason/Dixon line by late today.
223 PM EDT Sat Jun 7 2025 High pressure will provide a period of dry weather tonight. Chances for showers and a few thunderstorms increase Sunday afternoon as low pressure makes its way across the Ohio Valley.
1016 AM CDT Sat Jun 7 2025 - A cold front will bring showers and thunderstorms late this afternoon/evening, highest east of the Missouri River. - Gusty northwest winds of 35-45 mph possible Sunday with cooler temperatures in the upper 60s to low 70s.
- Winds behind a cold front on Sunday could bring some minor impacts. Upper low moving through southern Canada will dig down into the Dakotas and then MN this afternoon and tonight. This will help push a cold front through the forecast area tonight.
Another cold front drops in early Sunday morning shifting winds out of the north, then east by afternoon. Didn't stray far from model blends for low temperatures Sunday night except in the cooler valleys out west where they have been routinely dropping into the lower to mid 30s in the upper Rio Grande.
(Tonight through Sunday night) Hot and humid conditions are expected for Deep South Texas tomorrow, as upper level ridging and southeasterly surface flow persists over the region.
Opening the period with an upper ridge in place from the Gulf into northern Mexico. The high resolution convection-allowing models (CAMs) continue this feature east southeast the remainder of the day into northern AL with an outflow potentially sinking southeast into the northern zones this evening. The upper ridge over the Gulf and Deep South retreats to the southwest late in the weekend as a large deep closed low pressure system exits south central Canada and settles over the western Great Lakes region.
High pressure was located over eastern Lake Superior and extended to the southwest into the Central Plains. An area of low pressure over northern Manitoba trailed a cold front southward into North Dakota. Southerly winds on the backside of the high and ahead of the cold front are advecting moisture into the Northland. There may be a brief break in activity during the evening before the cold front arrives from the west with better forcing.
335 PM CDT Sat Jun 7 2025 - Showers and Isolated thunderstorms are possible tonight across northern Nebraska behind a cold front.

119 PM EDT Sat Jun 7 2025 - Cold front arrives Sunday night, bringing showers and cooler conditions to kick off next work week. eventually centering deep low pressure across the northern Lakes early next work week. Primary Forecast Concerns: Temperature/cloud trends and addressing Sunday afternoon shower (storm?) evolution ahead of approaching cold front. Sunday morning looks to remain dry, with shower chances gradually increasing during the afternoon as moisture advection continues to increase in maturing southerly flow ahead of the approaching cold front. Still mild, with highs on Sunday well up into the 70s away from the big waters, and lows Sunday night mostly in the lower 50s.
118 PM EDT Sat Jun 7 2025 A cold front will move southward across the region from north to south early tonight.
213 PM EDT Sat Jun 7 2025 High pressure will provide a period of dry weather tonight. Chances for showers and a few thunderstorms increase Sunday afternoon as low pressure makes its way across the Ohio Valley.
(This evening through Sunday Night) Hot, humid, and hazy conditions continue through the weekend as a strong ridge of high pressure builds over South Texas. Tomorrow is shaping up to be slightly warmer as hazy conditions begin to exit the region.
Current RAP analysis showing a broad upper level ridge building over the PNW while a weak closed low remains separated from the jet stream flow and meandering nearly stationary off the CA coast. The marine layer is a bit shallower than 24 hours ago but really not having much sensible impact under the ridge thanks to the reinforced onshore flow from the closed low.
545 PM MDT Sat Jun 7 2025 - A back door cold front Saturday night will bring scattered showers and thunderstorms to our northern zones late Saturday night/Sunday morning, followed by another round Sunday PM near the WY higher terrain.
1003 PM EDT Sat Jun 7 2025 Low pressure moves out to the Atlantic tonight.

657 PM CDT Sat Jun 7 2025 - Showers and Isolated thunderstorms are possible tonight across northern Nebraska behind a cold front.
720 PM EDT Sat Jun 7 2025 (Rest of today through Sunday) The northern stream will dip into the southern tier of the CONUS as a large area of low pressure drifts into the Northern Plains. At the surface, a west to east elongated ridge will remain centered in the west-central Atlantic, with its westernmost reach deep into the Gulf.
VFR conditions prevail mostly due to ridging and keeping things dry with light and variable winds.
617 PM CDT Sat Jun 7 2025 (This evening through Sunday Night) Hot, humid, and hazy conditions continue through the weekend as a strong ridge of high pressure builds over South Texas. Tomorrow is shaping up to be slightly warmer as hazy conditions begin to exit the region.
714 PM EDT Sat Jun 7 2025 High pressure will provide a period of dry weather tonight. Chances for showers and a few thunderstorms increase Sunday afternoon as low pressure makes its way across the Ohio Valley.
636 PM CDT Sat Jun 7 2025 - Cold front tomorrow afternoon brings a short window for severe storms across east-central KS.
(Tomorrow through Saturday) Most of Sunday will remain dry, but much warmer than today ahead of another cold front that will be approaching from the north and pushing through the area beginning mid-late afternoon.
658 PM CDT Sat Jun 7 2025 - A cold front will bring showers and thunderstorms late this afternoon/evening, highest chances east of the Missouri River. - Gusty northwest winds of 35-45 mph possible Sunday with cooler temperatures in the upper 60s to low 70s.
While amplified ridging takes place over the western CONUS, a dry eastern Pacific low will open and move into the desert southwest through early this coming week. The weak trough beneath the upper ridge will have little effect on temperatures with forecast highs through this period remaining just above normal.
As ridging over the Pacific Northwest begins to break down through the middle of the week, a trend toward cooler and more seasonable weather is anticipated as breezy onshore flow persists.
922 PM CDT Sat Jun 7 2025 - Winds behind a cold front on Sunday could bring some minor impacts. UPDATE A line of thunderstorms along a pre-frontal trough continues to propagate eastward this evening. Smoke will also begin to push into the region behind the cold front, lowering air quality and visibility. Upper low moving through southern Canada will dig down into the Dakotas and then MN this afternoon and tonight. This will help push a cold front through the forecast area tonight.
Currently, to our west in the Miss Delta region, shear profiles/hodographs are supportive of at least modest rotation in the low-levels given current storm trajectories. Given the possibility of some eastward translation of the more unstable air mass, and general maintenance of the low/mid shear across the region.
This is due to ridging in place. A surface Atlantic ridge has nudged a bit southward across South Florida due to troughing along the Atlantic Coast. The lower level ridge is aligned along our latitude, while ridging is in place aloft due to a cut off low over the northwestern Caribbean Sea. The narrow Atlantic ridge will remain across South Florida through the overnight period, keeping gentle east to southeasterly breezes. Expect overnight lows in the lower 80s with some protected locations possibly seeing near 80.
641 PM CDT Sat Jun 7 2025 (This evening through Sunday night) Tonight through Sunday night, weak zonal ridging will dominate the upper level pattern.
- Winds behind a cold front on Sunday could bring some minor impacts. A line of thunderstorms along a pre-frontal trough continues to propagate eastward this evening.

Aloft, mid- level ridging expands eastward through the Gulf and across the southern FL peninsula. 500 mb temps may be slightly cooler today at -7C to -8C with lapse rates modest at best. The WRLY flow in the mid-levels weakens by Tue/Wed with weak mid-level ridging building back toward the FL peninsula from the western Atlc. Continued generally favorable boating conditions through mid-week, as high pressure ridging remains across the south-central FL peninsula. Onshore flow develops and becomes more dominant Tue afternoon thru Thu as the ridge axis ventures northward.
Winds remain gusty out of the north and northwest, with cooler temperatures. - Early week remains dry, as upper level ridging builds into the region. Upper level analysis reveals an upper level low over north central North Dakota, with ridging over the Pacific Northwest. At the surface, a cold front has tracked through southern Nebraska early this morning, with high pressure building in behind the front. On satellite, a band of showers and thunderstorms is tracking across the northern Sandhills, behind the cold front. By Monday, the upper level low tracks across the Great Lakes, with upper level ridging building across the western United States.
Persistent troughing to our northwest continues to provide southwesterly moisture advection and modest synoptic forcing across our area.
349 AM CDT Sun Jun 8 2025 - Gusty northwest winds of 35-45 mph this morning with cooler temperatures in the upper 60s to low 70s.
401 AM EDT Sun Jun 8 2025 A cold front will slowly settle southward toward the area through today, then meander across the Mid-Atlantic through Monday.
1241 AM CDT Sun Jun 8 2025 (Tonight through Monday night) Oppressive heat continues through Monday as a result of sinking air (subsidence) from mid and upper level ridging, mostly sunny skies and humid air from breezy onshore southeasterly winds. This is expected to produce a major (level 3/4) heat risk across portions of the northern ranchlands (Brooks and Kenedy counties) as well as the lower and middle RGV on Sunday, expanding to most of these areas on Monday while the rest of deep south Texas experiences a moderate (level 2/4) heat risk.
Isolated severe along cold front by early evening with focus turning toward a severe storm complex expected to impacts portions of SE OK by late evening into early morning hours Monday. The local area will focus on the cold front moving into southern KS by mid afternoon and expectations are isolated to scattered storms will develop near the boundary and spread into NE OK by mid to late afternoon.
1025 PM CDT Sat Jun 7 2025 Updated aviation portion for 06Z TAF issuance - Widespread rain and scattered thunderstorms will move across the area on Sunday along a cold front. On Sunday, a cold front will move across the area, bringing a round of showers and scattered thunderstorms.
Highs will reach up into the low to mid 80s this afternoon after a muggy start with lows this morning in the low 70s.
Main story over the period continues to be the heat, as a strong high pressure ridge moves in over the region by Sunday afternoon. Satellite imagery shows just how defined this ridge is with extensive clearing just off the coast of the PacNW. Highs will be in the mid to upper 90s elsewhere across the lowlands.
1120 PM CDT Sat Jun 7 2025 - Winds behind a cold front on Sunday could bring some minor impacts. UPDATE A line of thunderstorms along a pre-frontal trough continues to propagate eastward this evening. Smoke will also begin to push into the region behind the cold front, lowering air quality and visibility. Upper low moving through southern Canada will dig down into the Dakotas and then MN this afternoon and tonight. This will help push a cold front through the forecast area tonight. Another reinforcing surge of cooler air will come down tomorrow as the upper low center moves into the midwest, with showers lingering through tomorrow and into Monday as the system pulls slowly into the Great Lakes.
Hotter temperatures are expected on Sunday as an upper ridge strengthens across the region.
While the cloud cover is keeping things fairly insulated this morning, we could still see some spots drop down into the lower 50s in the interior areas of the U. However, the rainfall will certainly help with future fire weather concerns as most spots should see at least a quarter of an inch of liquid by Monday morning! While the cloud cover will keep things a little cooler today in comparison to yesterday, expect highs to still get into the 60s over the U. , with the lower 70s still expected over the far east as some sunshine is expected at least early today. Expect more mild and moist conditions tonight into Monday as the wrap-around moisture of the low makes its way overtop of us.
- More widespread showers and thunderstorms expected late tonight into early Sunday morning along a cold front.
327 AM CDT Sun Jun 8 2025 - A cold front tomorrow afternoon brings a chance for storms across east central KS.
1222 AM CDT Sun Jun 8 2025 - Gusty northwest winds of 35-45 mph possible Sunday with cooler temperatures in the upper 60s to low 70s.
Mid-level ridging remains in place through Monday keeping quiet but warm conditions across South Texas. Have noticed some adjustments in the pattern with the mid-level ridge holding a bit longer, and only squashing a bit south, not moving as much to the west as it had previously shown.
235 AM EDT Sun Jun 8 2025 A break in the unsettled weather arrives today and Monday as high pressure briefly builds.
Temperatures along the Island Chain are in the lower 80s with dew points in the mid 70s. Strong surface Atlantic ridging remains the name of the game with the center of this high located near the Azores. The western periphery of this high extends westward into Florida and into the Gulf. Mean layer ridging will remain the name of the game through the forecast period. Breezes will become slightly stronger during the week as the high near the Azores shifts more to the central North Atlantic.
138 AM EDT Sun Jun 8 2025 Low pressure moves out to the Atlantic overnight.
However, there remains some uncertainty on just how well the low-levels truly recover in the wake of this morning's activity. Meanwhile, highs reach into the lower to middle 80s with dewpoints in the upper 60s.
Temperatures across the region will continue to climb as a ridge of high pressure builds over the area.
High pressure remains mostly in control off to the east, so don't expect a break in today's heat.
- The next round of thunderstorms will arrive Monday, along and ahead of a slow-moving cold front.
In the wake of the departing MCS, northerly winds and cooler weather should result in a break in showers and thunderstorms on Monday.
Today, the cold front is forecast to roughly remain situated over the Continental Divide.
However, another active day is expected tomorrow as a strong upper level trough will dig into the Upper Midwest forcing a cold front into the area. Out ahead of this front temperatures are expected to rise into the low to mid 80s this will help create a very unstable environment with afternoon MUCAPE values between 3000- 4000J/Kg. Monday the upper level trough will continue to dig into the Great Lakes region forcing a secondary cold front through the area.
149 AM EDT Sun Jun 8 2025 - Cold front arrives Sunday night, bringing showers and cooler conditions to kick off next work week. eventually centering deep low pressure across the northern Lakes early next work week. Primary Forecast Concerns: Temperature/cloud trends and addressing Sunday afternoon shower (storm?) evolution ahead of approaching cold front. Sunday morning looks to remain dry, with shower chances gradually increasing during the afternoon as moisture advection continues to increase in maturing southerly flow ahead of the approaching cold front. Still mild, with highs on Sunday well up into the 70s away from the big waters, and lows Sunday night mostly in the lower 50s.
The upper pattern this morning is defined by a broad ridge of high pressure across northern Mexico and a weak dry upper low parked off the coast of central California. The upper ridge will slowly shift west today and consolidate into a stronger ridge of high pressure in the Eastern Pacific off the coast of the northern Baja by Monday afternoon.
High pressure was located over eastern Lake Superior and extended to the southwest into the Central Plains. An area of low pressure over northern Manitoba trailed a cold front southward into North Dakota. Southerly winds on the backside of the high and ahead of the cold front are advecting moisture into the Northland. There may be a brief break in activity during the evening before the cold front arrives from the west with better forcing. An upper low associated with this system will drop out of the Canadian Prairies for Sunday into Monday. With cooler air filtering in and daytime heating, showers will remain possible each day with some embedded rumbles of thunder at times.
The flow from the east is very indicative of the area staying in the cooler area of this system. Beginning late Sunday afternoon through Sunday evening, some showers and even a rumble of thunder will become possible as a better piece of upper energy in the form of an upper low will approach the area late. This is the result of dew points staying in the lower 50s, and some semblance of a weak cap aloft limiting updrafts. Once the front moves through on Sunday night, we will maintain a chance of rain showers into Monday night as the upper low rotates over the region.
(Today through Monday) Mid-level ridging will remain in place across the area today, while the last remnants of a plume of Saharan dust lingers over the region. Temperatures will warm up as a result, with afternoon highs in the low 90s for the East Coast, and mid 90s for the interior. Ridging could weaken a little on Monday as a mid-level trough deepens across the Eastern Seaboard.
