159 AM EDT Tue Jun 3 2025 High pressure over the Ohio Valley will gradually build east towards the Mid-Atlantic through Tuesday.
- Periods of showers and thunderstorms are possible at times this week, with the highest rain chances Tuesday afternoon into Wednesday. By late this evening, a cold front will be entering our northern counties, and additional thunderstorms are expected to develop along the cold front and move south through our area tonight.
104 AM CDT Tue Jun 3 2025 (This evening through Tuesday) High pressure will move east through the state today with low and mid level winds out of the east. Tonight and Tuesday, the high pressure moves east of the area, stalling out along the east coast and western Atlantic. Winds could become breezy late in the afternoon Tuesday, but the area should remain rain free with the high pressure preventing more rain from moving or developing in the state.
- A cold front brings a Marginal Risk for severe thunderstorms on Wednesday with damaging wind gusts and small hail the main threats.
(Tonight through Wednesday night) Slack troughing extends along the central Gulf inland to portions of the NW Gulf Coast while midlevel subsidence appears on the 18Z sounding this afternoon. Wednesday, high pressure strengthens across the western Atlantic with light ridging extending toward the TX/LA Coast.
318 AM EDT Tue Jun 3 2025 Dry and warmer weather is expected through Wednesday under high pressure.
- Slow moving cold front to perhaps result in multiple rounds of showers and thunderstorms Wednesday through the end of the week. Well advertised warm-up has begun in earnest across the Great Lakes early this afternoon, driven by maturing southwest flow and nearly full column warm air advection on backside of slowly departing Ohio Valley high pressure. Moisture advection continues to increase Tuesday night into Wednesday as a cold front works slowly southeast across Michigan. Definitely something to monitor in the coming days with mid-range ensemble spread of this front from the lower Ohio Valley to southern Michigan (although latest progs are trending toward the former).
359 AM CDT Tue Jun 3 2025 - Showers and thunderstorms will linger this morning, with much cooler and windy conditions arriving from northwest to southeast.
1223 AM CDT Tue Jun 3 2025 A southern stream trough over the northeast Gulf will become a closed low overnight as it slowly meanders over the eastern Gulf. Given its relatively weak nature, and quite a bit of dry air in place, not expecting much in the way of impacts from this boundary and trough, at least as we head into tonight. Expect mostly clear conditions into the overnight hours, with temps falling into the lower to mid 60s by daybreak. 12Z global models continue to show a large and broad upper trof pattern from the western states to a portion of the eastern US. An inverted mid-level trof/low is progged to be aligned from the southeast U.
325 AM EDT Tue Jun 3 2025 A warming trend continues into the midweek period as high pressure drifts off the east coast.
Issued by National Weather Service State College PA 121 AM 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.
- Periods of showers and thunderstorms are possible at times this week, with the highest rain chances Tuesday afternoon into Wednesday. Ahead of this trough, an embedded disturbance will move east across our area this late evening and tonight. A dryline may mix as far east east as the far western parts of the Big Country (and just ahead of the approaching cold front). The airmass ahead of the dryline and approaching cold front will have moderate to strong instability.
Shorter nights as we approach the summer solstice was helping to keep fog from becoming more of an issue like in the cooler months. Depending upon how dense the high clouds coming in are, we could see a first 90 degree temperature for the year.
TODAY THROUGH THIS EVENING: Scattered to numerous showers/thunderstorms will continue across the region today through this evening, as a potent upper low approaches from the southwest, and a strong cold front moves in from the northwest, amidst a moist and weakly/uncapped airmass. Isolated instances of marginally severe storms are possible this morning, but thinking greater chances will hold off until early afternoon and persist through the evening, mainly along and east-southeast of the KS Turnpike, as instability increases ahead of the approaching cold front. greater than 3-4 inches) are unlikely though given the relatively fast-moving nature of the cold front. TEMPERATURES: A rather significant cool down is expected from northwest to southeast today in wake of the strong cold front, with temperatures likely falling into the 50s and 60s behind the front.
- Much cooler temperatures can be expected on Tuesday. An area of low pressure at the surface was centered over southeast Colorado earlier today, with a surface boundary extending south into the Texas Panhandle.
225 AM MDT Tue Jun 3 2025 - Daily chances for showers and storms through the work week, with the highest coverage of showers and storms expected today and Wednesday.
- Cooler conditions later in the week with additional chances for showers and storms. Scattered to widespread showers and storms will continue through the morning and into the afternoon hours as a cold front moves southward through the area. 0-3km shear and low-level helicity do increase substantially around 00Z Wed as the low-level jet strengthens. And given the high PW airmass and potential for training storms, there will be areas that see higher rainfall totals.
310 AM EDT Tue Jun 3 2025 High pressure will continue to provide warm and dry weather through Wednesday.
120 AM EDT Tue Jun 3 2025 Broad area of high pressure will allow for dry conditions to continue through mid week. The approaching mid level trough and associated cold front will be slow to influence the region as the broad area of high pressure and limited moisture will keep advancing mid/high clouds at bay for now, but mention of some sky obscuration due to high level smoke will continue. Daytime highs on Tuesday continue to trend warmer underneath the amplified H5 ridge. A cold front will pass early on Sat and clear out any lingering precip in the morning. Temps start warm in the upper 80s Wed, cooling to the upper 70s by Sat and Sun and trending warmer to around 80 on Mon.
- Another hot and humid day is expected today with upper ridging once again hindering convection - A return of daily diurnally driven showers and thunderstorms is expected tomorrow through the weekend.
Issued by National Weather Service State College PA 1234 AM 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.
Dry air filters into the region today following yesterday's cold front.
1202 AM EDT Tue Jun 3 2025 High pressure will keep tranquil weather across the area through Tuesday. , with a 590 dm ridge across the Carolinas. Low temperatures are forecast to range from the mid 60s inland to the low 70s along the coast. At the sfc, an inverted trough will lift across Florida, possibly developing a spot low off the Atlantic coast of FL late Wednesday.
311 AM EDT Tue Jun 3 2025 High pressure will continue to provide warm and dry weather through Wednesday.
- Much cooler weather expected Wednesday. (Tuesday through Wednesday night) Another disturbance will rotate around the base of the trough on Tuesday. As this occurs a surface cold front will surge south into the area. These storms will eventually consolidate into clusters or line segments/squall-line along the advancing cold front and will pose mainly a hail and wind threat. Breezy north winds will accompany the front with quite a bit cooler and drier overspreading the area. This will give a lull in the rain/storms for much of the day Wednesday with much cooler than normal temperatures for early June (highs in the 70s).
A secondary weak trough passing through the Northern Plains Wednesday accompanied by a jet streak in the upper-levels, CAPE progged around 600-800 Joules and a weak impulse of pacific moisture keeps general thunderstorm chances in the forecast for north-central Minnesota.
Hot and dry conditions will continue this week as a ridge settles into Northwest California. KEY MESSAGES: -Strong gusty winds at the coast and the highest exposed terrain will continue for Tuesday and diminish throughout the week. High pressure out in the eastern Pacific continues to push against a low pressure system ejecting further south of Northwest California. The highest gusts will linger over higher elevations and particularly at the King Range and the Klamath Mountains of Del Norte County. Warm and dry conditions will endure over Northwest California throughout the week as the ridge persists over the eastern Pacific. Slightly warmer than average high temperatures can be expected through the week, especially for the interior.
139 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.
1245 AM MDT Tue Jun 3 2025 - Cool again today, with rain shower/storm chances and snow for the higher elevations.
- Canadian wildfire smoke has returned behind the cold frontal passage. A quick moving mid level wave/MCV moving along highway 14 is speeding up the low level front a bit this afternoon. Rain will gradually come to an end from west to east on Tuesday morning, leading to a cooler and marginally breezy day.
1219 AM CDT Tue Jun 3 2025 (Tuesday through Wednesday) Mid-level ridge centered near Baja California Sur will build into Deep South Texas through Wednesday. Tuesday night will be warm and humid with lows in the upper 70s to the lower 80s.
300 AM EDT Tue Jun 3 2025 High pressure builds in from the west into midweek with seasonable and drier conditions expected. Weak low pressure will impact the area late week, with another cold front approaching and moving through this weekend. Otherwise, dry and benign conditions expected today with temps near climo, rising into the low/mid 80s interior to the 70s beachfront. Low temps warmer than this AM as the serly flow will advect more low level moisture off the Atlantic with highter TD's in place.
1050 PM MDT Mon Jun 2 2025 - Dry today and much cooler with highs in the 60s and 70s. Overnight lows will also be on the cooler side in the 30s/40s both tonight and Tuesday night, dropping down into the 20s in some of our colder mountain basins such as the Sawtooth Valley and Copper Basin. The overall pattern has a deeper reflection of low pressure over the Pacific Northwest/Northern Rockies before "flattening" out a bit by the weekend.
234 AM EDT Tue Jun 3 2025 High pressure builds in from the west into midweek with seasonable and drier conditions expected. Weak low pressure will impact the area late week, with another cold front approaching this weekend. As the high moves more overhead tonight, expect winds to calm, bringing good conditions for radiational cooling overnight. For Tuesday more of the same as high pressure remains over the area and conditions remain dry. Temperatures should top out in the low to mid 80s with some upper 70s along the Outer Banks.
Pattern Synopsis and Forecast: A building upper-level ridge over the Great Lakes will give way to an incoming trough and associated cold front tonight into Wednesday. Nearshore locations look to stay noticeably cooler as winds coming off of the cold lakes moderate temperatures. Pattern Synopsis/Forecast: Attention shifts to a cold frontal boundary sliding into the region tonight, with increasing shower and storm chances overnight and into Wednesday.
226 AM EDT Tue Jun 3 2025 High pressure will continue to provide warm and dry weather through Wednesday.
Parts of the Klamath River Valley in southwest Siskiyou County (Around Somes Bar) may be even warmer, with daytime highs 5-10 degrees above normal. Also, with the thermal trough situated along the coast, gusty northeast winds are also likely near and at the ridges into Wednesday night along the coastal mountains in southwest Oregon and western Siskiyou county. Surface analysis shows a strong thermal trough along the coast. This has resulted in gusty northeast breezes near and at the ridges in southwest oregon and western Siskiyou county. The thermal trough won't move much this evening and tonight, therefore gusty northeast breezes are likely to continue through tonight. An upper trough is moving south off the California coast.
553 AM EDT Tue Jun 3 2025 High pressure will continue to provide warm and dry weather through Wednesday.
Fairly dry air is noticed in the low water vapor channel while there is some moisture and the mid to upper levels.
518 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.
Forecast models do show some cloud cover moving into the region, which will likely keep temperatures slightly warmer than this morning. Then high pressure begins to strengthen along the west coast, causing temperatures to rise and decreasing the chance for any shower activity across western Montana and north central Idaho.
By late week, the low starts to lift a little farther north, but the current expectation is for the low to only make it off the coast of the Carolinas. This supports much of the Florida peninsula remaining in the upstream warm and humid fetch feeding into the center of the low, keeping higher rain chances in the forecast through much of the remainder of the work week. However, the highest rain chances and greatest accumulations in SWFL are likely over the next couple days. (12Z TAFS) Upper level low continues to spin in the Gulf This will give us more southeasterly winds today. As the low pulls away later in the week, winds are forecast to become lighter, and gradually veer back to the WSW towards the weekend as showers and thunderstorms continue to develop across coastal waters at times.
High pressure is centered along the East Coast this morning, and that means a southerly flow across Middle Tennessee.
634 AM 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. By late this evening, a cold front will be entering our northern counties, and additional thunderstorms are expected to develop along the cold front and move south through our area tonight.
- Much cooler weather is anticipated today with some locations 20-30 degrees cooler than 24 hours prior.
The area will slowly dry out as we head into the weekend with temperatures beginning to heat back up as a ridge attempts to build in. The cut-off low off the coast of southern California will move inland later this afternoon, becoming an open wave as it moves through to the south of our forecast area tonight and tomorrow. Areas south and east of the I-15 corridor will have the best chances at seeing convection this afternoon and evening as the cut-off low begins to move inland, providing additional lift/ instability to fuel storms.
The low pressure system that brought anomalous moisture and scattered to widespread rainfall to the region is seen on satellite lifting through east-central Colorado at this time. While light showers are continuing across the higher terrain of western Colorado mainly along the divide, eastern Utah and far western Colorado are already seeing plenty of clearing as drier air pushes in from the west. As the trough passes over the area it will provide large-scale lift therefore we are expecting another day of scattered to widespread showers and storms.
817 AM MDT Tue Jun 3 2025 - Daily chances for showers and storms through the work week, with the highest coverage of showers and storms expected today and Wednesday.
537 AM EDT Tue Jun 3 2025 Dry and warmer weather is expected through Wednesday under high pressure.

/EC/ Today and Tonight: It will be warmer than normal and continued dry through the period. Early morning water vapor imagery/RAP analysis showed the circulation around an upper level low spinning over the northeast Gulf. This low was beneath ridging aloft essentially forming a Rex block to our east. At the surface, ridging will continue to nose back across our CWA from the northeast, helping maintain a moist southeast to southerly flow across our CWA.
542 AM CDT Tue Jun 3 2025 - Showers and thunderstorms will linger this morning, with much cooler and windy conditions arriving from northwest to southeast.
1018 AM EDT Tue Jun 3 2025 High pressure builds in from the west through midweek with seasonable and drier conditions expected. Weak low pressure will impact the area late week, with another cold front approaching and moving through Eastern NC this weekend. Dry and benign conditions expected today with temps near climatology, rising into the low/mid 80s interior to the 70s along area beaches. Light winds this morning becoming southeasterly this afternoon as high pressure shifts offshore. Low temps warmer than this AM as the serly flow will advect more low level moisture off the Atlantic with higher dew points in place.
633 AM CDT Tue Jun 3 2025 Today and Tonight: It will be warmer than normal and continued dry through the period. Early morning water vapor imagery/RAP analysis showed the circulation around an upper level low spinning over the northeast Gulf.

707 AM EDT Tue Jun 3 2025 High pressure builds in from the west into midweek with seasonable and drier conditions expected. Weak low pressure will impact the area late week, with another cold front approaching and moving through this weekend. Otherwise, dry and benign conditions expected today with temps near climo, rising into the low/mid 80s interior to the 70s beachfront. Low temps warmer than this AM as the serly flow will advect more low level moisture off the Atlantic with highter TD's in place.
726 AM EDT Tue Jun 3 2025 Dry and warmer weather is expected through Wednesday under high pressure.
1217 PM CDT Tue Jun 3 2025 - Showers and thunderstorms will linger this morning, with much cooler and windy conditions arriving from northwest to southeast.
Aside from that, the rest of the forecast for this week will be mostly quiet as high pressure remains in control aloft while a drier airmass arrives late week (Saharan air dust plume). Otherwise, the main headlines will continue to be the warmer temperatures and increased heat risk as we head into the weekend.
Wednesday should turn out to be quite a nice day with limited sky cover and temps in the upper 70s as high pressure takes over.
- 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.
1202 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. By late this evening, a cold front will be entering our northern counties, and additional thunderstorms are expected to develop along the cold front and move south through our area tonight.
Pattern Synopsis/Forecast: Mid-upper level ridging currently situated to our east with upstream troughing making headway into the western Great Lakes. Primary focus locally over the next 24 hours revolves around upstream surface cold front, currently stretched from northwest Quebec southwestward across Ontario, the central U. High temps Wednesday expected to be some 10-20 degrees cooler than today -- back into the 60s for most with some early day low-mid 70s favored near Saginaw Bay.
(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.
Our attention turns farther north, where storms are foreast to develop in west-central and north-central Texas along a cold front.
Issued by National Weather Service Albany NY 431 PM EDT Tue Jun 3 2025 Surface and upper level ridges will remain over our area through Wednesday.
This cooler and stable (albeit moist) airmass should keep things quiet until a subtle disturbance has a 20-30% chance to generate scattered showers across the western Panhandles tonight into tomorrow morning. Overnight lows will be noticeably cooler, bottoming out in the 40s to low 50s for most locations.
Overnight lows will also be on the cooler side in the 30s/40s both tonight and Wednesday night, dropping down into the 20s for some of our colder mountain basins such as the Sawtooth Valley and Copper Basin.
422 PM EDT Tue Jun 3 2025 High pressure builds in from the west through Wednesday with seasonable and drier conditions expected. Weak low pressure will impact the area late week, with another cold front approaching and moving through Eastern NC this weekend. High pressure continues to shift offshore, away from the coast Wednesday with a broad area of weak low pressure starting to form off the GA/SC coast, slowly lifting north closer to Eastern NC late in the day.
