1251 AM CDT Sun Jun 8 2025 - Showers and Isolated thunderstorms are possible tonight across northern Nebraska behind a cold front.
435 AM EDT Sun Jun 8 2025 Chances for showers and a few thunderstorms increase this afternoon as low pressure makes its way across the Ohio Valley. A cold front will bring more numerous showers and thunderstorms Monday. High pressure slides eastward today allowing a surface wave to reach the Ohio Valley. Tonight, a secondary warm front will track north across the area, continuing the potential for showers.
During the remainder of the afternoon, some brief surface ridging will build in, providing dry conditions and some sunshine. A weak cold front will move into the forecast area this evening, on the eastern portion of an approaching upper trough.
323 AM EDT Sun Jun 8 2025 - Upper Low Brings some Rain next couple days - Low Confidence in Rain/Convection Late Week - Upper Low Brings some Rain next couple days Low pressure tracking across the Ohio Valley will bring light rain to the far southern zones today, while the rest of the forecast area sees rain chances increase late this afternoon. A line of showers and a few thunderstorms can be expected along a cold front in advance of a vigorous upper low moving across the Great Lakes region. The core region of the upper low moves in by Monday afternoon and combines with deeper moisture and steepening lapse rates to bring a diurnal enhancement of showers and thunderstorms in the afternoon and evening.
(Today and tonight) An upper level ridge continues to move into the Pacific Northwest and British Columbia, while an cutoff low to the west of California maintains the marine layer at around 1500 feet deep. Latest satellite imagery shows stratus clouds blanketing the coast and flowing into the inland valleys, with a cloudy morning expected for all but the highest elevations and the most interior valleys in the East Bay and Central Coast. Morning lows hover in the lower to middle 50s for the lower elevations, up to the lower 60s in the higher elevations.
714 AM EDT Sun Jun 8 2025 (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.
441 AM CDT Sun Jun 8 2025 - Severe storms will be possible this afternoon along an approaching cold front.
620 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.
A cold front moving west to east bringing showers and a few embedded storms continues to march eastward. The system will have cold air aloft with it, which will lead to cooler than normal temperatures today and Monday.
/26/ (Monday Night through Sunday) The northwest flow regime will continue through the first half of the week, with the large ridge positioned over the Rockies and a deepening low over the Great Lakes, opening up and lifting into southeastern Canada. By midweek, the northwest flow pattern at last begins to break down, but a developing trough and associated closed low over north Texas and Oklahoma will introduce southerly flow aloft, aiding in further development of thunderstorms impacting the region on a near daily basis, particularly our southern zones. This trough will slowly wobble to the north and east through the end of the week, when a new closed low will develop to take its place.

619 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.
Similar conditions to yesterday with weak surface ridging and large SAL aloft over the region to produce warm and humid surface conditions but dry air aloft, above 030k ft inversion as seen in morning sounding, to suppress diurnal convection in SW flow pattern regime. Very warm conditions expected again today across west central and southwest Florida as high pressure surface and aloft holds over the region.
This deep marine layer is thanks to the upper low hanging out a few hundred miles off of Central California combined with moderate to strong onshore flow (LAX-DAG pressure gradient peaking around 7.
618 AM EDT Sun Jun 8 2025 Chances for showers and a few thunderstorms increase this afternoon as low pressure makes its way across the Ohio Valley. A cold front will bring more numerous showers and thunderstorms Monday. High pressure slides eastward today allowing a surface wave to reach the Ohio Valley. Tonight, a secondary warm front will track north across the area, continuing the potential for showers.
Expect gradual clearing today ahead of a cold front with temperatures rebounding into the mid to upper 70s. During the remainder of the afternoon, some brief surface ridging will build in, providing dry conditions and some sunshine. A weak cold front will move into the forecast area this evening, on the eastern portion of an approaching upper trough.
Southern and central sections will likely have just isolated coverage at best due to drier and more stable profiles through the lower and mid levels. Discussion: In the upper levels, a trough is over the Central U. At the surface, a low moving through the Ohio Valley today will bring a weak cold front through the region late this afternoon or evening.
328 PM CDT Sun Jun 8 2025 - Warmer and drier conditions return through the beginning of the week.
- Unsettled weather beneath upper level low/cold pool Monday.
Isolated severe along cold front by early evening with focus turning toward a severe storm complex expected to impact portions of SE OK by late evening into early morning hours Monday. At 10 AM, an approaching cold front was draped from near St Joseph MO to Salina KS to Garden City KS. 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.
(Rest of today through Monday) Overall another nice day across South FL with upper level high pressure to our west over Mexico and to our east over the western Atlantic. This is helping to keep the trough across the eastern US from digging any further south that the SE US. Only large scale change on Monday is that the upper level high over Mexico will slide to the west into the eastern Pacific.
Unsettled weather will continue this period with a front lingering to the west and and upper trough remaining to the west. Lows tonight will fall to the low to mid 70s with highs Monday invof 90 away from the beaches. A cold front will approach from the west during the period while an upper trough affects the area.

(Today and tonight) An upper level ridge continues to move into the Pacific Northwest and British Columbia, while an cutoff low to the west of California maintains the marine layer at around 1500 feet deep. Latest satellite imagery shows stratus clouds blanketing the coast and flowing into the inland valleys, with a cloudy morning expected for all but the highest elevations and the most interior valleys in the East Bay and Central Coast. Morning lows hover in the lower to middle 50s for the lower elevations, up to the lower 60s in the higher elevations.
The air mass hasn't modified a whole lot, but dewpoints in the upper 60s instead of the low to mid 70s will make it feel slightly more comfortable outside.
- Dry and seasonably hot weather will return by midweek with afternoon highs in the low-to-mid 80s and overnight lows in the mid 60s.
With high low level moisture and cooler temps overnight, fog development is possible in many areas. And with a southerly component to the low level winds, with a westerly direction at the mid levels, a few storms could rotate with a tornado possible.
Expect gradual warming through midweek with Moderate Heat Risk for much of the lower elevations. An upper-level trough and associated low remains off the Central CA coast and is forecast to move inland tonight into Monday.
1205 PM CDT Sun Jun 8 2025 (Tonight through Monday night) Very warm and breezy conditions continue through Monday as the subtropical ridge weakens but holds through the short term period. There remains a moderate risk of life-threatening rip currents along the lower Texas coast with very inviting beach weather.

Winds remain gusty out of the north and northwest, with cooler temperatures. - Early week remains dry, as upper level ridging builds into the region.
Broad low pressure was located over northwestern Ontario this afternoon with a cold front stretching across eastern Wisconsin into western Illinois and southwestward into the Plains. A trough of low pressure was analyzed over central Minnesota. Daytime heating and cool air aloft behind the cold front was leading to scattered showers and isolated thunderstorms across northern Minnesota and northern Wisconsin. As an upper low moves through the region on Monday, another day of diurnally driven showers and isolated thunderstorms is expected across the region.

A weak area of low pressure approaching the West Coast is helping to enhance moisture and instability along a lee-side trough stretching from the Sierra into west-central Nevada. Storm development will initially focus over the higher terrain before drifting into valleys, especially across Mineral and southern Lyon counties. Moderate HeatRisk is expected across much of the lower elevations.
In the early morning, a cold front will enter the region from the northwest moving southeast. Along and ahead of the cold front, a line of showers and storms will also move through. Towards the afternoon, the upper trough will begin to swing over the region and mid-level flow will increase allowing for storms to develop along and east of I-65.
- Below normal temperatures to start the week, but warmer air builds in mid-late week.
(This evening through Monday) An upper level trough just to our west will produce a small upper level cutoff low which is expected to slide into Central CA late tonight and into early tomorrow morning.

Upper level ridge over the region will bring warm temperatures through Monday.
635 PM CDT Sun Jun 8 2025 - Cold front has already moved through east-central KS, limiting the main severe weather risk.
We will see clearing take place then overnight and on Monday morning as we will become under the influence of the dry slot between the front and the upper low during this period. Then, the upper low will arrive Monday afternoon during peak heating.
Meanwhile, troughing over the eastern United States is resulting in a broad mid level col across Florida and a weakening upper trough over Cuba and the northwestern Caribbean Sea is resulting in weak ridging aloft. Surface conditions are seasonably warm and humid with temperatures in the lower to mid 80s and dew points in the mid 70s. Overall the environment Surface through lower level ridging will continue to dominate through the overnight. With that said, forecast soundings indicate inhibition is expected to remain weak and some moistening will take place through the lower levels. Expect seasonably warm conditions will overnight lows broadly in the lower 80s and dew points remaining in the mid 70s. Atlantic ridging reaching across South Florida will drive gentle east to southeasterly breezes on Keys waters through the overnight period.
Temperatures will generally be near their seasonal averages this week, though interior temperatures might rise a few degrees each day (This evening through Monday) An upper level trough just to our west will produce a small upper level cutoff low which is expected to slide into Central CA late tonight and into early tomorrow morning. Expect onshore flow to usher in the marine layer again tonight, leading to cloudy skies and cooler temperatures.
This is where the highest chances will be be as the sea breeze moves inland.
Gusty SW flow will remain less than 10 kts overnight shifting a bit more westerly as trough shifts eastward. Unsettled weather will continue this period with a front lingering to the west and and upper trough remaining to the west.

709 PM MDT Sun Jun 8 2025 - Scattered showers and thunderstorms mainly over the higher terrain and Palmer Divide this evening.
704 PM EDT Sun Jun 8 2025 (Rest of today through Monday) Overall another nice day across South FL with upper level high pressure to our west over Mexico and to our east over the western Atlantic. This is helping to keep the trough across the eastern US from digging any further south that the SE US. Only large scale change on Monday is that the upper level high over Mexico will slide to the west into the eastern Pacific.
Broad low pressure was located over northwestern Ontario this afternoon with a cold front stretching across eastern Wisconsin into western Illinois and southwestward into the Plains. A trough of low pressure was analyzed over central Minnesota. Daytime heating and cool air aloft behind the cold front was leading to scattered showers and isolated thunderstorms across northern Minnesota and northern Wisconsin. As an upper low moves through the region on Monday, another day of diurnally driven showers and isolated thunderstorms is expected across the region. Mostly VFR though that should change overnight as more IFR rolls in as a low pressure center rotates north of the border.
- Severe storms will be possible this afternoon/evening along a cold front along and south of a Moberly to Paola line.
pdf A remnant outflow boundary/trough will continue to push southeast or east-southeast through rest of the afternoon into the evening over southeast GA. Lows tonight will fall to the lower to mid 70s with winds becoming lighter from the southwest at 5-10 mph.
635 PM CDT Sun Jun 8 2025 - Warmer and drier conditions return through the beginning of the week.
Flat ridging and downslope flow will bring warm and dry conditions to the area today with high temperatures in the 80s to near 90 degrees. As ridging flattens out, southwesterly flow will allow for increased moisture and instability.
Area will be on the southern fringe of an upper trough over the eastern CONUS, centered over the Great Lakes with a cut-off low. In the low levels, the Atlc ridge axis will remain just to our south which will maintain the offshore (SW) flow today. The ridge axis will start to lift north Tue across central FL with a more southerly flow pulling some higher moisture into the area. Temperatures will remain hot and humid with afternoon highs in the low to mid 90s and peak heat indices of 100-105F. The eastern CONUS trough lifts out and mid level ridging from the SW Atlc will redevelop over FL. This will allow the low level ridge axis to lift north to its climatological position near 30N lat.
between a pronounced upper level ridge over the Intermountain West and a pronounced upper level trough over the Mississippi River Valley. with highs in the lower 80s. as the aforementioned ridge flattens and shifts eastward across the Rockies (tonight) and Central Plains (Tue-Tue night). trapped /nearly cut-off/ beneath the ridge.
Please see the previous forecast discussion down below for more information: Global guidance continues to show a cold front shifting southward and stalling across the southeastern CONUS heading into Tuesday.
Updated at 141 AM CDT Mon Jun 9 2025 - Mainly dry and a bit cooler early this week. (Today and tonight) Cooler and somewhat drier air will filter south in the wake of last nights MCS and a weak cold front that will push south through the area this morning. This will result in a quieter day with slightly cooler temperatures across Oklahoma and north Texas. There is an outside chance for a storm or two this afternoon across western north Texas with perhaps a better chance during the evening hours as convection develop across the High Plains of New Mexico and then propagates southeast toward western north Texas.
Upper level ridge over the region will bring warm temperatures through Monday. The ridge will weaken Monday and exit the region on Tuesday.
We will see clearing take place then overnight and on Monday morning as we will become under the influence of the dry slot between the front and the upper low during this period. Then, the upper low will arrive Monday afternoon during peak heating. - Brief dry period mid-week Tuesday will see less of a chance for rain showers as the upper low settling in on Monday will be lifting out on Tuesday.
Dry on Tuesday behind a cold front. A trough over the Great Lakes will be pushing a cold front down towards the Mid South, and the trough will pick up an MCV from today's Red River OK/TX storms. A notable feature in forecast soundings tomorrow is an inverted-V profile in the low levels, indicating good mixing that should help storm downdrafts bring winds aloft to the surface, enhanced by evaporative cooling. Southern and western sections have the highest severe potential, with the expected timing between 4 pm and 9 pm EDT. Additional showers and a few thunderstorms may continue overnight associated with the passage of the surface cold front and 850 mb trough.
1235 AM CDT Mon Jun 9 2025 - Warmer and drier conditions return through the beginning of the week.
A weak cold front was moving through the area, and an upper trough was interacting with this front to bring the showers and storms. Late this afternoon, another cold front will move in from the northwest. Upper troughing will still be across the area, and the northern forecast area will be on the fringes of an upper jet. Cooler air moving in behind the front will allow for lows in the lower to middle 50s.
