346 PM EDT Tue Jun 3 2025 High pressure off of the coast and an upper level ridge in the eastern U.
(Rest of today through Wednesday) High pressure is sitting off to our east and we are under the apex of a strong ridge. This will bring hot conditions today with highs pushing into the upper 80s and possibly the lower 90s. The ridge will start to push to the east Wednesday but we will remain under its influence keeping things dry and quiet.
On Wednesday, the upper low lifts into Canada with the trailing trough axis settling a little further west into the Great Basin.
307 PM CDT Tue Jun 3 2025 - Rainfall activity will gradually end throughout the day, with some lingering showers into the evening hours - Temperatures will be much cooler this afternoon compared to the last few days, with afternoon readings only maxing out in the lower to middle 60s.
The cold front has cut southwest to northeast across the state and convection on this axis will be the area to watch for any stronger storm development the rest of today.
(Rest of Today and Tonight) Scattered cumulus clouds have formed over the past few hours with temperatures climbing into the lower to mid 80s. Models continue to show an upper low stalling just west of the Florida panhandle today with a strong area of upper level ridging remaining in place to the north of it over the Tennessee valley.
(Through Wednesday) An upper level low near the West Coast of Florida will drift north across the forecast area over the next couple of days. This will bring some mostly beneficial rainfall to the region with highest rain chances to the east of where the low tracks.
953 AM MDT Tue Jun 3 2025 - Unsettled weather is expected through the weekend with a general warming trend 07z surface analysis had high pressure over MT nosing into the central plains behind a cold front stretching from southern MN to northern CO. Water vapour loop had upper trough over central Canada into the northern Plains.
951 AM PDT Tue Jun 3 2025 A low pressure system will bring a chance of showers and thunderstorms for this afternoon into tonight across Southern California and the coastal waters, decreasing late tonight.
Latest WV satellite imagery shows an upper low just off the southern California coast that will shift eastward tonight through Wednesday, moving through Arizona and shearing out as it does so.
Issued by National Weather Service State College PA 1220 PM EDT Tue Jun 3 2025 Warm air will continue to build on the back side of dry high pressure during the next couple of days.
Continue to protect sensitive vegetation - Showery this evening in northwest Montana - High pressure will build into the weekend bringing a warming trend Some embedded moisture in northwest flow aloft will keep isolated showers and thunderstorms in the forecast for northwest Montana this afternoon and evening, especially over the Continental Divide north of about Highway 200. Northwest flow aloft will continue through mid week as a ridge of high pressure builds over the West Coast. The ridge axis will move over the Northern Rockies this weekend.
(Tonight through Wednesday night) Hot and generally rain-free conditions will prevail through the period across Deep South Texas as the region remains under the influence of the northern/northeastern periphery of a mid-level ridge centered over Mexico. The combination of persistent low level southerly to southeasterly flow and warm temperatures will result in a moderate heat risk region wide on Wednesday with highs ranging from the low to mid 90s along the immediate coast to around 100 degrees across the Rio Grande Plains.
Meanwhile, to the west, a cold front extending from the central U. The cold front and it's associated showers will move slowly/steadily across the area Wednesday.
The upper ridge shifts east tomorrow. This opens the door for an area of low pressure across the FL Panhandle to slide further north through the day.
Issued by National Weather Service Morristown TN 1206 PM CDT Tue Jun 3 2025 (Rest of Today and Tonight) Scattered cumulus clouds have formed over the past few hours with temperatures climbing into the lower to mid 80s. Models continue to show an upper low stalling just west of the Florida panhandle today with a strong area of upper level ridging remaining in place to the north of it over the Tennessee valley.
- Much cooler weather expected Wednesday. (Rest of today and tonight) Ongoing severe convection will continue along and ahead of an advancing cold front, which will move through central into southeast Oklahoma this afternoon and this evening. Much drier and cooler air will overspread the the area behind the cold front.
325 PM CDT Tue Jun 3 2025 Tonight through Wednesday night: Onshore flow will become a little more cyclonic, moist, and unstable as an upper low drifts inland from the gulf into the southeast CONUS. Otherwise, expect near to slightly warmer than normal temperatures, and the potential for late night/early morning fog confined mostly to southeast portions of the area.
High pressure at the surface builds into the area as well with light winds and cool temperatures in the 40s expected for Wednesday morning.
- Cooler conditions later in the week with additional chances for showers and storms. Todays forecast will continue to be stormy and rainy as a result of an upper wave an a cold front in the area moving very slowly to the southeast. Temperatures Wednesday will be a bit cooler after the passage of the cold front and mainly in the 70s across the area.
1242 PM EDT Tue Jun 3 2025 Dry and warmer weather is expected through Wednesday under high pressure.
Currently cyclonic flow around a low pressure system way up in Canada is allowing some isolated to scattered showers across eastern Montana and northwestern North Dakota. This lower pressure is also allowing the classic diurnal cumulus clouds to form across the state. Temperatures will slowly warm up into the mid and upper 70s as that low pressure system mentioned above slides east. This will flatten the northwest flow over the Northern Great Plains, allowing warmer temperatures.
1202 PM EDT Tue Jun 3 2025 High pressure will continue to provide warm and dry weather through Wednesday.
Additional things we're keeping track of include the atypical stratus pattern as we switch between a low pressure to high pressure pattern as well as some haze in the area as smoke from the Canadian wildfires continues to move into the area. Fairly dry air is noticed in the low water vapor channel while there is some moisture and the mid to upper levels.
218 PM EDT Tue Jun 3 2025 High pressure will continue to provide warm and dry weather through tomorrow.
Most/all of the showers and storms are expected to form over the higher terrain where it will be unstable and then drift eastward.
The upper level low continues to spin off the West Coast of Florida as evident on satellite and radar.
This week, the Pacific Northwest (PacNW) will be under a northwest flow pattern, caught between a ridge of high pressure over the northeast Pacific and a trough over the Great Basin.
Adjusted PoPs downward a bit for most of the area during the late evening and early overnight period in line with latest radar/obs and guidance, otherwise grids are decent shape with the latest thinking, as an upper low continues to spin over the E Gulf advecting moisture across the area with rounds of showers and embedded storms expected to continue tonight with coverage likely increasing into Wednesday morning. The upper level low continues to spin off the West Coast of Florida as evident on satellite and radar.
The forecast area will remain wedged between troughing across the nation's mid-section and a mid/upper level lower pressure system currently meandering over the eastern gulf. This is resulting in high pressure at both the surface and aloft holding in place across the Lower Mississippi River Valley. With quiet weather expected overnight, lows tonight will be slight warmer than previous nights as they range from the upper 60s east to the lower 70s west. /19/ Tonight through Wednesday night: Onshore flow will become a little more cyclonic, moist, and unstable as an upper low drifts inland from the gulf into the southeast CONUS. Otherwise, expect near to slightly warmer than normal temperatures, and the potential for late night/early morning fog confined mostly to southeast portions of the area.
A cold front pushing through the central Plains and Upper Midwest will be the catalyst for these threats as the front enters the forecast area late this evening. CAMs do show additional development upstream of the main line due to support from the low-level jet and mid-level vorticity maxima as well as southwesterly corfidi vectors.
(Tonight) With a mid and upper level ridge axis now to our east along the east central Coast, flow has become southeast to south. A light southeast to south surface flow will keep temperatures mild overnight with dew points staying in the lower 60s.

The last time BNA was 90 degrees or warmer was October 6, 2024. There will be an upper low that will be lifting northwestward out of Florida through the day which may get close enough to spark a shower or storm along the plateau during the afternoon. (Rest of today through Wednesday) High pressure is sitting off to our east and we are under the apex of a strong ridge. This will bring hot conditions today with highs pushing into the upper 80s and possibly the lower 90s. The ridge will start to push to the east Wednesday but we will remain under its influence keeping things dry and quiet.
624 PM CDT Tue Jun 3 2025 - Periods of showers and thunderstorms are possible at times this week, with the highest rain chances Tuesday afternoon into Wednesday. (This evening through Wednesday) The current weather indicates a cold front moving south across the South Plains. The main players for convection this afternoon and tonight will be a cold front moving across the area late tonight and a dryline for a few hours this afternoon. The main round of thunderstorms will be late tonight as CAM models indicate a line of storms developing along the southward moving cold front, located along a San Angelo to Brownwood line by midnight. Expect mainly quiet weather Wednesday and cooler temperatures.
629 PM CDT Tue Jun 3 2025 Tonight through Wednesday night: Onshore flow will become a little more cyclonic, moist, and unstable as an upper low drifts inland from the gulf into the southeast CONUS. Otherwise, expect near to slightly warmer than normal temperatures, and the potential for late night/early morning fog confined mostly to southeast portions of the area.
Issued by National Weather Service Morristown TN 446 PM CDT Tue Jun 3 2025 (Rest of Today and Tonight) Scattered cumulus clouds have formed over the past few hours with temperatures climbing into the lower to mid 80s. Models continue to show an upper low stalling just west of the Florida panhandle today with a strong area of upper level ridging remaining in place to the north of it over the Tennessee valley.
710 PM EDT Tue Jun 3 2025 High pressure will continue to provide warm and dry weather through tomorrow.
This high will move out into the Atlantic later this week, resulting in a return to gentle to moderate east to southeast breezes and less rainy and thundery conditions.
Isolated showers and thunderstorms are possible today as an upper low moves into the area. An upper low has destabilized the air mass today creating isolated showers and thunderstorms. This morning the focus was across SLO County, but as the low moved south through the day the focus shifted to mostly LA and Ventura Counties with a solid line of storms between Catalina and San Clemente Islands. Can't rule out some isolated flooding issues in the mountains along with small hail and gusty winds and isolated showers across the lower elevations through this evening.
125 AM EDT Wed Jun 4 2025 (Through Wednesday) An upper level low near the West Coast of Florida will drift north across the forecast area over the next couple of days. This will bring some mostly beneficial rainfall to the region with highest rain chances to the east of where the low tracks.
Discussion: High pressure remains over the area at the surface for the period. A weak upper low lifting out of the northern Gulf will will track slowly northeast across the southeastern states during the period.
357 AM CDT Wed Jun 4 2025 - Cooler, below normal temperatures expected through the end of the week.
- Cooler temperatures for Wednesday, before a warming trend into the weekend. (Today and tonight) A cold front was moving through the area early this morning, resulting in thunderstorms across parts of our Heartland area, and also a few showers in the Concho Valley. Temperatures will be cooler today, with highs mainly in the 80s.
At the start of the forecast period, our area is compressed between ridging to our east and a weak trough with attendant cold front moving in to the area from our west. The aforementioned cold front will move through the area today. Will continue to include prevailing showers into tonight as another upstream mid level trough aides in rain shower coverage.
WEATHER PATTERN OVERVIEW: An upper trough over central Canada and the northern Plains will keep northwest flow into eastern Montana through much of the week. With the eastward movement of the trough, heat building into the Great Basin will spread northward, bringing slightly above normal temperatures into Montana. By the end of the week, an upper ridge will be in place over the west with a stacked low pushing through Manitoba. Tightening gradient between the high and low could bring stronger winds into eastern Montana. With warmer and drier conditions also expected, fire weather concerns may be elevated for the weekend depending on timing and strength of frontal boundaries.
Issued by National Weather Service Albany NY 118 AM EDT Wed Jun 4 2025 Surface and upper level ridges will remain over our area through Wednesday.
Today-Tonight: Smoke Gradually Clears A ribbon of surface smoke has settled in early this morning from west-central Wisconsin into north-central Iowa in the wake of yesterday's cold front passage. Aside from some passing high clouds and a few pockets of daytime cumulus, look for plenty of sun today once the smoke clears, helping to keep highs near seasonal norms despite the cooler airmass in place.

- Cooler and wetter conditions expected through the end of the work week.
A closed low is currently centered over the AZ/CA border and is kicking off showers and thunderstorms over western and northern Arizona. Through the day the low begins to open up and moves through central Arizona.
Issued by National Weather Service Fort Worth TX 1227 AM CDT Wed Jun 4 2025 (This evening through Wednesday Night) The synoptic scale pattern this afternoon features broad troughing over much of the Central and Western CONUS, with ridging over the Eastern US. Near the surface, high pressure is centered near Delmarva, with ridge influence extending west/southwest into the OH/TN Valley and Deep South. Several areas of low pressure exist west of this ridge, one over the Midwest and another over the western Great Lakes, with a cold frontal boundary extending from these areas S/SW into the Southern Plains. On Wednesday, the front is expected to stall/weaken, with ridging attempting to build in the mid and upper levels. Wednesday night, the frontal boundary is expected to lift slightly north as a warm front.
1257 AM MDT Wed Jun 4 2025 - A bit warmer today, through still cooler than normal for early June.
550 AM CDT Wed Jun 4 2025 - Cooler temperatures for Wednesday, before a warming trend into the weekend. (Today and tonight) A cold front was moving through the area early this morning, resulting in thunderstorms across parts of our Heartland area, and also a few showers in the Concho Valley. Temperatures will be cooler today, with highs mainly in the 80s.
646 AM EDT Wed Jun 4 2025 High pressure will continue to provide warm and dry weather through this evening. Southwest flow around the high, along with increased heights due to the ridge will result in another day of warm and dry conditions. Key Message: 1) Rain chances increase later this week and into the weekend A disturbance off the Carolina Coast is looking to form into a low pressure system and travel along the coast towards the northeast.
Otherwise, high pressure will settle over srn WI for tnt-Thu. High temps in the lower to middle 70s well inland today with 60s over far ern WI, followed by middle to upper 70s inland for Thu.
536 AM EDT Wed Jun 4 2025 Dry and warmer weather is expected today under high pressure. Shower and thunderstorm chances return Thursday with an approaching cold front.
225 AM MST Wed Jun 4 2025 - Scattered showers and isolated thunderstorms will remain possible mainly across south-central Arizona this morning and over the higher terrain through this afternoon.
The low stratus deck that's been over the area for the last 30 hours or so is slowly breaking up, and that trend should continue through the rest of the morning hours. Most/all of the showers and storms are expected to form over the higher terrain where it will be unstable and then drift eastward.
Under generally clear skies, temperatures ranged from the lower 60s in parts of southern middle Tennessee to around 70 elsewhere.
- Scattered showers will remain possible mainly across south- central Arizona this morning and over the higher terrain through this afternoon.
Broad troughing and strong onshore flow will bring night through morning low clouds and fog and cooler than normal temperatures through the end of the week. Another trof moves into the area on Thursday. A high hgt (579 dam) upper low pinches off from the trof and retrogrades to the west. Hgts do rise and this will likely smoosh the low clouds out of some of the vlys.
- Cooler and wetter conditions expected through the end of the work week. Severe storms are not expected as cooler air behind the cold front has lead to a much more stable atmosphere. Heading into Wednesday, a broad upper-level trough will still be locked in place over most of CONUS. This trough will continue to stay in place throughout much of the week leading to cooler and wetter conditions both Wednesday and Thursday.
A weak cold front will cross the region Thursday with a round of scattered showers and thunderstorms.
Moisture associated with these features combined with persistent surface ridging from the northeast and daytime heating will fuel convection mostly around the periphery of our CWA today. This activity will see a distinct diurnal trend so wl not carry the low chance for convection into the Tonight period. Otherwise, warmer than normal temperatures will continue through the period.
631 AM CDT Wed Jun 4 2025 A weak upper low will lift northward into Florida panhandle today. Meanwhile, at the sfc, a weak inverted trough will also lift northward into the area. This will setup a gradient in rain chances on Wednesday with the highest rain chances across the east with lower chances in the drier air to the west.
617 AM CDT Wed Jun 4 2025 - Cooler and less humid conditions today and Thursday, with highs in the mid 70s.
High temperatures are forecast in the low 80s under mostly cloudy skies. Global model soundings suggest a dry layer developing in the low levels below 700mb potentially settling closer to the surface by early Thursday morning.
Strong high pressure remains positioned offshore for the next several days.
A few cooler spots have briefly fallen into the upper 30s to low 40s.
- Scattered showers and isolated thunderstorms will remain possible mainly across south-central Arizona this morning and over the higher terrain through this afternoon.
