Another warm and dry day can be expected with flat ridging over the region. Temperatures will be a few degrees cooler than Tuesday, with highs in the 70s to middle 80s.
A cold front over far southeastern Kentucky during the pre-dawn hours will exit east as an upper trough axis over the Mid-Ohio River Valley lifts northeast this morning. Weak upper level ridging then builds over the Mid-Ohio River Valley region Wednesday. Satellite and CAMS continue to indicate widespread fog and low stratus formation behind the cold front over central through northeastern Kentucky. Widespread valley fog formation is again expected tonight behind the secondary cold front and upper trough passage. Wednesday will be rather quiet with weak upper ridging overhead yielding relatively dry and stable conditions, but with temperatures warming about 4 to 5 degrees on average from Tuesday's highs into the lower to mid-80s.
- Smoke/haze possible through the period Current upper air analysis depicts upper level ridge over the western US while upper level trough sits over the eastern US. East- west oriented sfc trof/weak frontal boundary descends into western SD by early afternoon with narrow corridor of 500-1500 J/kg SB CAPE developing along it.

639 AM CDT Tue Jun 10 2025 (Today through Wednesday) Upper trough over the Great Lakes with the trough axis southward to near Pensacola early this morning with upper ridging over the Intermountain West. If anything, moisture levels may be a bit higher tomorrow, so we cannot really back off of the high probabilities for the 12 hour period.
Aloft we have northwesterly flow as troughing moves into the Ohio River Valley. The RRFS shows the highest near surface signal back across SE Dakota early this morning and observation out there are not detecting any visibility restrictions.

617 AM EDT Tue Jun 10 2025 Chances for a few showers today as an upper level trough moves through.
553 AM CDT Tue Jun 10 2025 - Hot on Wednesday with highs in the low to mid 90s.
Models suggest another round of elevated shower coverage developing this evening in the CWA, though the easterly track of the cells could result in the Upper and Middle Keys getting more rainfall than the Lower Keys. From synopsis, a broad high pressure moving into the central North Atlantic will support gentle to moderate east to southeast breezes, with the potential for moderate to fresh breezes towards late week.
543 AM CDT Tue Jun 10 2025 - Warmer today with an isolated storm potential this afternoon.
A pattern change aloft will see a steady transition to cooler weather through the week as onshore flow strengthens.
626 AM CDT Tue Jun 10 2025 (Tonight through Wednesday night) The subtropical ridge breaks down as low pressure works into North Texas and the Southern Plains by Wednesday night.

433 AM CDT Tue Jun 10 2025 The upper trough over the eastern CONUS will lift northeast, followed by an upper ridge building over the southeast states through midweek. An upper level low will likely get squished between two large highs in an omega block over Texas keeping us on the soggy east side.
629 AM CDT Tue Jun 10 2025 - Warmer temperatures expected today.
Issued by National Weather Service St Louis MO 418 AM CDT Tue Jun 10 2025 - Warmer today, but low humidity will keep conditions relatively comfortable.
Issued by National Weather Service State College PA 1015 AM EDT Tue Jun 10 2025 A cold front will cross the area later today.
* Hot and dry weather will prevail this week with slightly cooler temperatures by the weekend. Broad high pressure across the West will dampen today as weak low pressure traverses the Pacific Northwest.
The slight ridge pattern is turning into a more zonal upper level pattern. It also means today will be cooler for the more interior areas that haven't been seeing those strong pushes of low level clouds from the marine environment.
649 AM CDT Tue Jun 10 2025 The upper trough over the eastern CONUS will lift northeast, followed by an upper ridge building over the southeast states through midweek. An upper level low will likely get squished between two large highs in an omega block over Texas keeping us on the soggy east side.
Issued by National Weather Service Corpus Christi TX 556 AM CDT Tue Jun 10 2025 (Today through Wednesday) A deep upper level trough covers most of the eastern half of the country this morning. The low level flow is from the southeast bringing a warm, moist airmass to the CWA. The upper flow over TX is west-northwesterly on the backside of the trough.
622 AM EDT Tue Jun 10 2025 A cold front will slowly shift east today and keep a lingering threat of showers/storms in the Piedmont.
Issued by National Weather Service St Louis MO 629 AM CDT Tue Jun 10 2025 - Warmer today, but low humidity will keep conditions relatively comfortable.
Short range mixing heights are progged to exceed 800 mb, which will translate to high temperature sin the low to mid 90s. With convective temps very near the high temperatures, a stray shower or storm cannot be entirely ruled out from 4-8 PM today.
- At and above normal temperatures through the end of the work week, with continued daily chances for afternoon showers and storms, mainly over and near the higher terrain. 50s and 60s were noted over the higher terrain. Storms should remain primarily isolated over the higher terrain. These storms that push onto the lower terrain may produce some localized strong gusty winds.
Issued by National Weather Service Pittsburgh PA 225 PM EDT Tue Jun 10 2025 Chances for a few showers today as an upper-level trough moves through. Drier weather returns Wednesday with high pressure.
- Cooler and wetter conditions anticipated for much of this week, with heavy rainfall and strong thunderstorms possible at times. CAMs show a line of thunderstorms developing late this evening across the Big Bend and Permian Basin on the leading edge of the upper low and the moving across west central Texas overnight. As the upper-level low deepens, cooler air should move in aloft and allow for some scattered thunderstorms to develop by late morning through early afternoon.
By Wednesday AM, southwest flow will increase aloft as a weak mid- level trough lingers across central Texas. 5-2") and lifting a warm front north to the I-30 corridor.
Otherwise, highs are forecast to reach the lower to mid 80s later this afternoon. A mild night will then follow, as lows drop into the lower to mid 60s.
Issued by National Weather Service Pittsburgh PA 206 PM EDT Tue Jun 10 2025 Chances for a few showers today as an upper-level trough moves through. Drier weather returns Wednesday with high pressure.
Issued by National Weather Service Topeka KS 1138 AM CDT Tue Jun 10 2025 - Warmer today, but low humidity will keep conditions relatively comfortable.

Issued by National Weather Service Corpus Christi TX 1240 PM CDT Tue Jun 10 2025 (Today through Wednesday) A deep upper level trough covers most of the eastern half of the country this morning. The low level flow is from the southeast bringing a warm, moist airmass to the CWA. The upper flow over TX is west-northwesterly on the backside of the trough.
The synoptic flow on Thu and Fri will mostly be defined by a broad, low amplitude trough over much of eastern Canada. a somewhat dampened ridge over the Southeast US and a cutoff low in the Southern Plains.
338 PM EDT Tue Jun 10 2025 A cold front will continue to produce a broken line of showers and thunderstorms across the Champlain Valley into Vermont through early this evening.
1237 PM CDT Tue Jun 10 2025 - After a noticeably cool start to the day (40s in many spots), the heat will turn up across the local area with high temperatures climbing into the lower 90s this afternoon.
1015 AM CDT Tue Jun 10 2025 Fairly benign weather today for the majority of the forecast area, as a front lies just north of the Highway 84 corridor.
1221 PM CDT Tue Jun 10 2025 The upper trough over the eastern CONUS will lift northeast, followed by an upper ridge building over the southeast states through midweek. An upper level low will likely get squished between two large highs in an omega block over Texas keeping us on the soggy east side.
(Rest of today through Wednesday) As the mid-level trough deepens across the CONUS eastern seaboard, activity amps up today as the southeasterly winds escort more moisture into the region with the help of the sea breezes. On Wednesday, as we await the return of the western Atlantic high and ridging, the models are continue to indicate there will be surge of moisture into South Florida, as PWATs are forecast to climb to 2.
1010 AM CDT Tue Jun 10 2025 - Warmer today with an isolated storm potential this afternoon.
Fairly benign weather today for the majority of the forecast area, as a front lies just north of the Highway 84 corridor.
High pressure at the surface and aloft will provide a dry middle of the week as temperatures warm back closer to seasonal norms with time.
354 PM EDT Tue Jun 10 2025 A line of showers and embedded thunderstorms will push across the region into the early evening hours along a passing cold front.
Key Message(s): - Scattered afternoon convection Wednesday: A weak cold front will remain stalled across the forecast area Wednesday providing focus for convective initiation.
Dry, breezy, and slightly cooler conditions are expected Wednesday onward. Another day of record to near record heat over portions of southern Nevada and southeast California as high pressure ridge remains firmly in place.
quarter size or greater) also exists with any of the stronger storms, marginal CAPE and high freezing levels may inhibit hail growth and the ability for larger stones to make it to the surface. Slightly cooler air aloft will move in today, which combined with better surface moisture, will aid in the development of afternoon and evening showers and thunderstorms. A relatively compact upper low then sets up near the BC coast late this week into the weekend. Several waves pivoting around the base of this upper low will eject toward the Northern Rockies, which will promote several more rounds of showers and thunderstorms.
Scattered showers and thunderstorms are expected again today over the higher terrain, then becoming limited to far eastern Arizona on Wednesday. Warmer and drier conditions return for the rest of the week with southwesterly afternoon breezes. A few isolated showers and thunderstorms have begun to develop across the higher terrain this afternoon with mid-level moisture still in place.
207 PM EDT Tue Jun 10 2025 - Dry conditions persist and temperatures trend warmer into tonight and Wednesday.
Meanwhile, the airmass across NE FL has destabilized beneath the cold pool and upper trough drooped across the eastern US. Additional showers and isolated storms will be possible across SE GA, mainly west of Waycross, late this evening and potentially after midnight as another impulse rounds the base of the upper trough. Though some high cloud associated with convection will push in from the northwest tonight, temperatures should cool in to the low 70s inland and mid/upper 70s at the waterfront areas.
1124 AM CDT Tue Jun 10 2025 (Tonight through Wednesday night) The subtropical ridge breaks down as low pressure works into North Texas and the Southern Plains by Wednesday night.
Light isolated showers continue to be possible now through 00Z or so, as a weakening cold front passes across the area. 01 inches with these showers remain around 10-20 percent, indicative of the low end chance. Limited vorticity at 700-mb supports the idea of this cold front weakening as it passes through the area, and any showers that result, lacking vertical depth. Tonight, skies will clear behind the frontal passage, as rising heights and high pressure build into the region. Wednesday, high pressure continues to build into the region, with sunny skies and above normal temperatures, in the low to mid 80s, and lows in the upper 50s.
While instability will be on the lower side over this timeframe, a dry boundary layer through the mid- levels will help to support instances of marginally severe winds. This will be especially true beneath any shower or thunderstorm that is collapsing as it moves off of the higher terrain, most notably through the afternoon hours. A relatively compact upper low then sets up near the BC coast late this week into the weekend. Several waves pivoting around the base of this upper low will eject toward the Northern Rockies, which will promote several more rounds of showers and thunderstorms.
249 PM EDT Tue Jun 10 2025 (Rest of today through Wednesday) As the mid-level trough deepens across the CONUS eastern seaboard, activity amps up today as the southeasterly winds escort more moisture into the region with the help of the sea breezes. On Wednesday, as we await the return of the western Atlantic high and ridging, the models are continue to indicate there will be surge of moisture into South Florida, as PWATs are forecast to climb to 2.
Broad zonal flow is then expected to set up across interior NorCal through the remainder of the week, until troughing arrives by the weekend. * Today: -Comparatively cooler temperatures today, although areas of Moderate HeatRisk persist.
301 PM EDT Tue Jun 10 2025 High pressure remains intact through the majority of the work week, keeping the forecast dry. Best potential for overland fog will be in the lower Scioto Valley and north-central KY tonight, so included a mention there.
- Warmer and gradually more humid conditions will begin to prevail, with fairly regular chances of rain by late week. In non-smoke news, high pressure over the Appalachians will remain in place through mid week, with its westward influence extending to the mid-Mississippi Valley. A cold front associated with a short wave currently near Lake Winnipeg will subsequently get hung up near the Illinois/Wisconsin border Wednesday night, with rain remaining north of it. Southerly winds around the high will gradually bring more moisture into the region on Wednesday, though dew points still remain relatively comfortable (upper 50s to near 60). Upper level low pressure has developed over north central Texas, and longer range model guidance continues to gradually lift it northeast toward St.
An upper level ridge of high pressure is currently building over the area, with rising 500 mb heights. All this to say, high temperatures at the coasts will be in the 60s and 70s, while warmer valleys will be in at least low 90s, and the far interior (such as Antelope Valley) will be in the high 90s to low 100s today and Wednesday.
(Tonight) High pressure over MO and AR will shift east into the OH and TN valleys tonight. With dew points mixing/advecting into the upper 50s to lower 60s, overnight lows should dip into the lower 60s.
(This evening through Wednesday night) Starting with the upper levels, a north/south trough axis extends from the Great Lakes to the Florida Panhandle and ridge centered over the Desert Southwest encompasses the rest of the country. As you'd expect this time of year, frontal boundary associated with the trough has stalled along the northern Gulf Coast.
- The pattern remains active through the end of the week with precipitation chances of 20-60% After a cool morning in the upper 40s to low 50s, the smoke filtered sunshine this morning already boosted temperatures to the lower to mid 70s as of Noon, and highs remain on track to reach the upper 70s to around 80. Certainly we'll need to watch the binary nature of this event, typical for summer warm frontal convection for either ramp up in coverage, or a dry forecast all together.
1220 PM CDT Tue Jun 10 2025 Fairly benign weather today for the majority of the forecast area, as a front lies just north of the Highway 84 corridor.
114 PM EDT Tue Jun 10 2025 (Today through Wednesday) Mid-level ridging across the area will continue to weaken today as a mid-level trough deepens across the Eastern Seaboard.
1239 PM CDT Tue Jun 10 2025 (Today through Wednesday) Upper trough over the Great Lakes with the trough axis southward to near Pensacola early this morning with upper ridging over the Intermountain West. If anything, moisture levels may be a bit higher tomorrow, so we cannot really back off of the high probabilities for the 12 hour period.
Models suggest another round of elevated shower coverage developing this evening in the CWA, though the easterly track of the cells could result in the Upper and Middle Keys getting more rainfall than the Lower Keys. That is not to say that the Lower Keys won't see any showers, but the coverage should be less. In addition, an inverted trough associated with an easterly undulation will sharpen somewhat as it approaches the Keys tonight. That being said, have nudged up PoPs to "likely" but have kept them below the higher end solutions.
Warmer and drier conditions return for the rest of the week with southwesterly afternoon breezes. Another round of showers and storms is expected this afternoon, especially across the higher terrain from the Rim and north.
301 PM EDT Tue Jun 10 2025 A cold front will stall over the area Wednesday. High pressure will prevail late week into the weekend. As an upper-lvl ridge builds in over the region, a weak front will park itself nearby across the Southeast before largely washing out. Simultaneously, an upper-lvl trough overhead will continue to lift northeastward.
A much stronger trof moves through Wednesday and expect widespread showers and thunderstorms with a better chance to see severe storms Wednesday afternoon.
1228 PM CDT Tue Jun 10 2025 - Warmer temperatures expected today.
1126 AM CDT Tue Jun 10 2025 - Hot on Wednesday with highs in the low to mid 90s.

Overnight lows are forecast in the lower to mid-70s.
Discussion: Upper trough will continue to eject north and east tonight into Wednesday.
722 PM EDT Tue Jun 10 2025 (Rest of today through Wednesday) As the mid-level trough deepens across the CONUS eastern seaboard, activity amps up today as the southeasterly winds escort more moisture into the region with the help of the sea breezes. On Wednesday, as we await the return of the western Atlantic high and ridging, the models are continue to indicate there will be surge of moisture into South Florida, as PWATs are forecast to climb to 2.
757 PM EDT Tue Jun 10 2025 High pressure remains intact through the majority of the work week, keeping the forecast dry.
Multiple boundary interactions in Orlando caused storms to become nearly stationary for a bit, producing 3-5" of rainfall from Four Corners to Oak Ridge, Winter Garden, and Pine Hills. Overnight lows are forecast in the lower to mid-70s.
Issued by National Weather Service Wichita KS 519 PM CDT Tue Jun 10 2025 - Warm and dry conditions today, with afternoon highs in the low to mid 90s.

651 PM EDT Tue Jun 10 2025 - Much warmer Wednesday with highs in the 80s and becoming drier.
851 PM EDT Tue Jun 10 2025 A line of showers and embedded thunderstorms will push across the region into the early evening hours along a passing cold front.
346 PM MST Tue Jun 10 2025 - Dry conditions with temperatures remaining 3 to 5 degrees above average across the lower deserts through the rest of this week - A strengthening ridge of high pressure over the Desert Southwest this weekend will promote the hottest temperatures of the year thus far.
The ridge that brought the extreme heat to the region over the past couple of days will weaken as a weak trough over the eastern Pacific moves into the west coast. On Wednesday, a weak trough off the Pacific coast will usher in a drier southwest flow which is expected to lower the anonymously high PWs back to near normal which will pretty much put an end to the daily isolated thunderstorms. With the trough, we can expected to see heights falling just a bit, but with increased mixing we are only expecting to see temperatures drop about 2-4 degrees.
740 PM EDT Tue Jun 10 2025 A cold front will slowly move to the coastal Carolinas by Wednesday and stall over the area.
556 PM EDT Tue Jun 10 2025 - Dry conditions persist and temperatures trend warmer into tonight and Wednesday.
641 PM CDT Tue Jun 10 2025 (Tonight) High pressure over MO and AR will shift east into the OH and TN valleys tonight. With dew points mixing/advecting into the upper 50s to lower 60s, overnight lows should dip into the lower 60s.
Convection has created a gust front with winds 45 to 55 mph moving east through the Lower Treasure Valley and Ada County as to 8:45 PM MDT.
Scattered showers and thunderstorms expected again today over the higher terrain, then becoming limited to far eastern Arizona on Wednesday. Warmer and drier conditions return for the rest of the week with southwesterly afternoon breezes.

619 PM CDT Tue Jun 10 2025 - Highs on Wednesday will climb into the low to mid 90s, marking the warmest day of the year so far for most areas.
The axis of a stronger ridge is now setting up over the Rockies, with several disorganized vort-maxes continuing to rotate over the top of the feature. A weak back door cool front will drift into the High Plains overnight and bring weak upslope winds, higher dewpoints, and more cloud cover to start our Wednesday. Expect highs to be a few degrees cooler than today as a result. Expect the first round of widely scattered showers and thunderstorms to initiate over the higher terrain in the early afternoon hours (or perhaps even late morning) and drift eastward through the afternoon.
GOES nighttime satellite imagery is highlighting partly cloudy skies across the Island Chain, with temperatures generally in the lower to mid 80s at most communities. As the axis of the associated ridge sags slightly further southward across the Florida Peninsula, moderate to occasionally fresh breezes will be possible late this week.
