626 AM EDT Sun Jun 9 2024 Low pressure is expected to bring showers to the region today, especially in the morning and early afternoon.
559 AM CDT Sun Jun 9 2024 - Very nice weather for today and Monday with highs in the lower 80s, light winds, and ample sunshine.
925 AM EDT Sun Jun 9 2024 Low pressure is expected to bring rain to the region today, especially in the morning and early afternoon.
611 AM CDT Sun Jun 9 2024 (Today and tonight) Upper ridging will continue to dominate to our west today with the center of the upper high settled near the Four Corners. A weak cold front currently draped across the central Texas Panhandle will push into our northern zones by late morning and through our southern zones by the afternoon. The upslope flow will aide with convective development along the higher terrain of New Mexico by the late afternoon. Models continue to be in agreement with convection developing as a weakness in the upper high passes overhead. These storms will also help to cool overnight temps into the low to upper 60s area wide.
One more warm and dry day today with a few showers over the Cascades as a weak upper-level trough passes through the region.
A weak cold front pushing through the area tonight will bring slightly cooler temperatures to the northern Nevada Monday with highs mainly in the 80s.
1001 AM EDT Sun Jun 9 2024 A cold front tracks across the area today with scattered showers and thunderstorms mainly in the mountains. Scattered showers/storms mainly west I-77 and south of the VA/NC border as a cold front moves through. Cooler and drier follows beginning tonight. Surface cold front extends from central PA to eastern KY, then west into Oklahoma. Increased gusts slightly today as a portion of this should mix down with the rain, especially at the higher elevations. Although PWATs are around an inch, there is plenty of dry air to overcome in the lower levels so probability for measurable rainfall is relatively low today. Overnight lows drop into the low to mid 50s for the mountains as upslope clouds diminish in the wake of the dry air.
The aforementioned convection was occurring along the periphery of an upper lvl ridge that was centered along the Gulf Coastal region. Elsewhere, dry conds are expected for the rest of the mrng, but convective chcs wl incrs this aftn as a large scale upper trof apchs fm the Plains.
(The rest of today ) A cold front is currently pushing into northeast OK. Behind the front, much cooler and drier air is filtering into the area. West and south of the front temperatures are much warmer and more humid.
421 AM CDT Sun Jun 9 2024 - Dry and breezy today as a backdoor cold front moves through the region.
644 AM EDT Sun Jun 9 2024 High pressure and a drier airmass will build into the region today, leading to near normal temperatures. A cooler airmass will briefly settle into the Ohio Valley on Monday before warmer temperatures return through the end of the week. The cold front will continue to push southeast across our area through mid morning. This will also allow for a cooler airmass to settle into the area for Monday with daytime highs only in the upper 60s to lower 70s.
530 AM EDT Sun Jun 9 2024 Light rain and/or drizzle will continue through 9am this morning with a passing cold front.
645 AM CDT Sun Jun 9 2024 Showers and thunderstorms are expected across the Mid-South into tonight as a cold front moves through the Lower Mississippi Valley. A ridge of high pressure will build in behind the front bringing cooler and drier air for the start of the week. The ridge will build across the region with hot temperatures in the lower to middle 90s expected by late week.
The flow pattern turns more from the southwest this evening ahead of a low pressure trough coming over the Rockies.
635 AM CDT Sun Jun 9 2024 - An upper trough and weak cool front will bring thunderstorm chances late Monday afternoon into Monday night.
726 AM EDT Sun Jun 9 2024 Light rain and/or drizzle will continue through 9am this morning with a passing cold front.
The forcing mechanism for all this activity is a weak, but not insignificant, trough that is moving into the region this morning. As this trough pushes farther inland, shower and thunderstorm activity will increase again later today. The most notable cooling is expected east of the Cascades where high temperatures are expected to be about 7 to 10 degrees cooler. The trough will push the moist unstable air and associated shower/thunderstorm activity east of the area by early this evening, and the atmosphere will stabilize for much of the week. We'll see a transition to zonal flow on Monday, but heights will build with some semblance of a flat ridge over the region.
Going into the mid and late afternoon, scattered showers and thunderstorms will develop area-wide as a cold front drops into the Mid State. A drier period moves in after that to start the week, with a Midwest trough swinging southward Monday but looking dry at the moment. (Monday Night through next Sunday) Ridging looks to work its way in for the remainder of the week, with a warming trend through the week as well.
The highest CAPE (500 to 1,000 J/kg) looks to be for areas south of I90, where gusty winds and hail may accompany the stronger cells.
Ample heating has warmed temperatures into the mid to upper 80s as of 18z, with SPC mesoanalysis data showing SBCAPE values between 1500-3000 J/kg (with the highest values west of I-65).
Highs are forecast to reach the low to mid 90s along the coast, and into the mid to upper 90s across the interior.
1220 PM CDT Sun Jun 9 2024 - Very nice weather for today and Monday with highs in the lower 80s, light winds, and ample sunshine.
*Temperatures will be on the rise through the end of the week as high pressure brings a stretch of rain-free weather with low humidity, light winds, and plenty of sunshine. A reinforcing shot of cold air will be ushered in overnight behind a secondary cold front, allowing temperatures to drop into the upper 40s in the northern tier and the upper 50s in the southeast. Another chilly night is in store for Monday night with lows ranging from the mid 40s at higher elevations in the Laurel Highlands and northwest mountains to mid 50s in the Lower Susquehanna Valley.
1148 AM CDT Sun Jun 9 2024 (The rest of today ) A cold front is currently pushing into northeast OK. Behind the front, much cooler and drier air is filtering into the area. West and south of the front temperatures are much warmer and more humid.
1243 PM EDT Sun Jun 9 2024 A cold front moves through on Sunday followed by a secondary weak cold front on Monday.
A weak cold front will try to move through the area later in the night, bringing slightly cooler conditions to northern Nevada tomorrow with with several degrees of cooling.
Cooler and fairer weather on Monday. A cold front is accompanying and helping to trigger these convective rounds, and it will do a good job of pushing the rain track to our south. Temperatures will be a little cooler than normal on Monday thanks to cooler air infiltrating in behind the surface cold front.
314 PM CDT Sun Jun 9 2024 - Nice weather continues for Monday with highs in the lower 80s, light winds, and ample sunshine.
Once the moisture increases in the low levels, moderate to heavy rain will be the issue with these storms. A cold front tracks across Northern Rockies tonight, which brings widespread precipitation.
(This evening through Monday Night) Shower and thunderstorm chances will begin to increase tonight, as upper-level ridging begins to break down ahead of the trough and cold front.
This activity is ahead of a cold front which extends across portions of northwest Tennessee and northeast Arkansas. As the front moves south today into warmer air, additional thunderstorms may develop. ARS Showers and thunderstorms are expected across the Mid-South into tonight as a cold front moves through the Lower Mississippi Valley. A ridge of high pressure will build in behind the front bringing cooler and drier air for the start of the week. The ridge will build across the region with hot temperatures in the lower to middle 90s expected by late week.
With only modest instability across the area and weak shear in the lowest 6 km, this activity will likely be very pulsey in nature and will likely not pose much of a severe threat. A cold front will make progress through the area tonight which will help to knock low temperatures down a few degrees from where they have been the past few days into the upper 60s to low 70s. There may be a slight increase in upper level support with increased northwest mid-level flow on the backside of the upper low in eastern New Mexico by tomorrow afternoon which could enhance development. With the chances for rain and cloud cover expected, temperatures will be much cooler in the 80s to low 90s.
1253 PM CDT Sun Jun 9 2024 - An upper trough and weak cool front will bring thunderstorm chances late Monday afternoon into Monday night.
pdf Dry and a little warmer tonight with shallow inland ground fog potential, mainly across NE FL near and south of the I-10 corridor. High pressure begins to nudge south of the local area as a trough deepens across the eastern CONUS. With the approaching trough, westerly winds will remain a little more elevated tonight (2-4 mph) bringing slightly warmer low temperatures compared to this morning, ranging from the lower 70s inland to mid/upper 70s toward the St.
An upper-level ridge remains situated across the NE Gulf as the upper-level NW flow around the high continues to advect a continental airmass across the FL peninsula.
234 PM EDT Sun Jun 9 2024 A cold front may bring a few showers today.
Surface winds outside of storms: variable or NW 5- 15 kt, except NW 15-35 kt this evening with cold front. Surface winds outside of storms: NW 5-15 kt, except 15-35 kt with cold front passage at approximately Mon/00-03Z.
Showers and thunderstorms are expected across the entire region tonight as a cold front moves through the Mid-South. A few strong to severe thunderstorms are possible south of the cold front.
Current infrared satellite imagery reveals cumulus buildups initiating off the higher terrain in Mono and Mineral counties, as well as the Lassen County convergence zone into far northern Washoe County. These areas will see the highest chances (20-40%) for another round of afternoon showers and thunderstorms today. A trough digging into the western US today squeezes off into a closed low off the coast of southern California on Monday, with upper-level ridging filling back in overhead.
1249 PM CDT Sun Jun 9 2024 (Today and tonight) Upper ridging will continue to dominate to our west today with the center of the upper high settled near the Four Corners. A weak cold front currently draped across the central Texas Panhandle will push into our northern zones by late morning and through our southern zones by the afternoon. The upslope flow will aide with convective development along the higher terrain of New Mexico by the late afternoon. Models continue to be in agreement with convection developing as a weakness in the upper high passes overhead. These storms will also help to cool overnight temps into the low to upper 60s area wide.
350 PM CDT Sun Jun 9 2024 - The entrance of a high pressure combined with clear skies will cause temperatures to drop quickly overnight.
- High pressure brings dry conditions for the first half of the week. Southeast Michigan positioned late this afternoon within the broad cyclonic expanse of a closed low lifting into southern Quebec. Weak cold frontal passage underway marking the transition toward deeper layer northerly flow. Cooler northerly flow entrenched throughout Monday as high amplitude troughing takes residence just to the east.
158 PM EDT Sun Jun 9 2024 High pressure and a drier airmass will build into the region today, leading to near normal temperatures. A cooler airmass will briefly settle into the Ohio Valley on Monday before warmer temperatures return through the end of the week. This will also allow for a cooler airmass to settle into the area for Monday with daytime highs only in the upper 60s to lower 70s.
Passage of a cold front from north to south will shut off rain chances for areas north of I-40 by 8 PM, and across southern areas by midnight. Later tonight, drier and cooler air with a high pressure system from Canada will start to move in.
(This evening through Monday) Isolated to widely scattered showers and thunderstorms will continue to develop this afternoon across southern Oklahoma and north Texas-- near and south of the cold front.
1233 PM CDT Sun Jun 9 2024 - Dry and breezy today as a backdoor cold front moves through the region.
120 PM EDT Sun Jun 9 2024 A cold front may bring a few showers today.
146 PM EDT Sun Jun 9 2024 A cold front will drop through the Carolinas this evening moving east and south lingering near the Southeast coast on Monday.
238 PM EDT Sun Jun 9 2024 A cold front moves through on Sunday followed by a secondary weak cold front on Monday.
327 PM EDT Sun Jun 9 2024 A cold front will move through tonight brining only scattered showers and storms as well as ending the heat heading into Monday. Highs Monday will be in the low to mid 80s. Some guidance paints the high QPF along the immediate coast whereas others keep it over the water.
These lingering clouds may keep a few locations over the southern Edwards Plateau slightly cooler today, but overall hot and humid conditions are seen across South Central Texas this afternoon. Expect high temperatures to be a bit cooler tomorrow so no Heat Advisory is anticipated.
Given the low chances, will not include in the individual terminals and will handle with amendments as needed.
A much cooler night is in store with low temperatures falling into the upper 50s. - High pressure builds over the region to start off the week allowing for below normal temperatures to continue. Dry weather and a warming trend then is expected through the middle of the week with highs reaching the low 90s by late week. A cold front will slowly sag south through this evening as one final cluster of showers are now moving across the FA. Have bumped down NBM maxTs a few degrees this afternoon as the additional pcpn will keep temps a bit cooler.
With high pressure expanding over the eastern forecast area today into tonight, the stage will be set for overnight temps in the 30s again tonight into Sunday morning. Guidance, even 10th to 25th percentile ensembles, remains above freezing but with a good portion of the area around 35 to 38 degrees. Drier mid level air and no vort lobes in the exiting upper trough should leave clear skies. Light winds at the surface under the high also help to create the perfect radiational cooling set up. The high keeps the region dry through Sunday even as it exits into Iowa by Sunday afternoon. Temperatures will climb closer to normal Sunday afternoon as an upper ridge begins to translate farther east and waa creeps in. Sunday night the incoming upper level ridge is parked over the Rockies putting us in northwesterly flow aloft.
(Today and tonight) Today much of the region will be sandwiched between an area of low pressure over the eastern Gulf and a weak front approaching from the north. Highs today are forecast in the low to mid 90s with max heat indices in the upper 90s to low 100s. Low temperatures overnight are forecast a tad bit warmer with increasing moisture, ranging from the low to mid 70s.
733 AM CDT Sat Sep 6 2025 - Cooler than normal again today, with a chance for patchy frost tonight in central MN.
641 AM EDT Sat Sep 6 2025 - Cool this weekend with highs in the 60s and lows in the lower 40s.
652 AM CDT Sat Sep 6 2025 Updated at 629 AM CDT Sat Sep 6 2025 - Lingering showers and thunderstorms behind a cold front will be clearing out by Saturday afternoon.
545 AM EDT Sat Sep 6 2025 Showers and possibly a rumble of thunder will accompany a weak cold front overnight and into the morning. Dry and cooler temperatures expected Saturday afternoon into Sunday. By this time, the prior wave will have pushed the surface cold front SE through most of the region; this means buoyancy will be neigh available and lightning potential will be low (let alone any severe threat). As the upper trough axis inches near the region late in the day, the precipitation line will shift east of the area as dry slotting begins to erode clouds west to east.
626 AM EDT Sat Sep 6 2025 (Today and tonight) Today much of the region will be sandwiched between an area of low pressure over the eastern Gulf and a weak front approaching from the north. Highs today are forecast in the low to mid 90s with max heat indices in the upper 90s to low 100s. Low temperatures overnight are forecast a tad bit warmer with increasing moisture, ranging from the low to mid 70s.
Otherwise, look for temperatures to slightly rebound from the cold frontal passage with afternoon highs returning to the 70s to low 80s.
* Cooler and drier air returns to the region tonight.
With moisture remaining across the region, still anticipate that we will see storms developing across the higher terrain and then moving down into the lower elevations.
1055 AM EDT Sat Sep 6 2025 Showers and possibly a rumble of thunder will accompany a weak cold front overnight and into the morning. Dry and cooler temperatures expected Saturday afternoon into Sunday. By this time, the prior wave will have pushed the surface cold front SE through most of the region; this means buoyancy will be neigh available and lightning potential will be low (let alone any severe threat). As the upper trough axis inches near the region late in the day, the precipitation line will shift east of the area as dry slotting begins to erode clouds west to east.
624 AM CDT Sat Sep 6 2025 - Scattered showers and thunderstorms are expected to return today as moisture pools ahead of a cold front that will push through the region early Sunday.
Lows are expected to fall into the low to mid 30s across much of the area. UPDATE Temperatures continue to vary across northwest MN, with a few locations dropping to the lower 30s earlier but others already increasing as low clouds fill in. Large scale mid/upper troughing associated with the Hudson Bay low remains in place, with northerly flow over our region. The Hudson Bay low begins to break down allowing for mid level ridging to build east.
A cold front dropping southeast through the forecast area through this afternoon, will result in showers and storms affecting the forecast area through mainly the morning and early afternoon hours. With cooler drier air over-running the CWA through the course of the morning, convection is forecast to dissipate across the area through the afternoon, despite the front continuing its southeast trek through the area. High pressure will build into the region in the wake of the front as it clears the CWA late in the afternoon. The resulting advecting cooler drier airmass into the region will result in a wide array of high temperatures across the forecast area today. Therefore, look for them to range from the upper 70s across the Delta to the lower 90s across the Pine Belt region.
- Warmer weather expected for the work week with highs back in the upper 70s to mid 80s.
Relatively cooler temperatures will also overspread the region by mid week.
UPDATE Cold temperatures continue over the area, with the coldest temperatures over western North Dakota where many locations dipped to or below freezing. Current surface analysis places deep low centered over James Bay, while high pressure stretches through Saskatchewan into the western Dakotas. For today, cyclonic flow aloft may keep a few clouds over eastern portions of the area, but this will come to an end later today into this evening as ridge over the western CONUS starts its gradual push east.
600 AM CDT Sat Sep 6 2025 (Tonight through Sunday) Storms remain across Tennessee at this hour near the cold front. These boundaries, the cold front moving through from the northwest, and cyclonic flow aloft around the base of the anomalous trough across the central/eastern US/Canada will contribute to higher chances of showers/storms. Drier air filters in behind the front Saturday night and Sunday while troughing remains over the eastern CONUS.
640 AM CDT Sat Sep 6 2025 - Sub-freezing temperatures over parts of western North Dakota this morning. Cold temperatures continue over the area, with the coldest temperatures over western North Dakota where many locations dipped to or below freezing. Current surface analysis places deep low centered over James Bay, while high pressure stretches through Saskatchewan into the western Dakotas. For today, cyclonic flow aloft may keep a few clouds over eastern portions of the area, but this will come to an end later today into this evening as ridge over the western CONUS starts its gradual push east.
625 AM CDT Sat Sep 6 2025 Updated at 608 AM CDT Sat Sep 6 2025 - Rain and thunderstorms will come to an end by Saturday afternoon, giving way to cooler temperatures this weekend. (Tonight through Sunday Night) A strong upper level low is set up over southern Ontario dropping a cold front south into Middle TN. As the trough digs early Saturday morning we will see the front stall out over the region with periods of showers and thunderstorms ahead of it. Highs on Saturday will be much cooler only making it into the low to mid 70s. Quiet and pleasant weather can be expected for the second half of the weekend as high pressure builds in from the Plains.
751 AM EDT Sat Sep 6 2025 Showers and possibly a rumble of thunder will accompany a weak cold front overnight and into the morning. Dry and cooler temperatures expected Saturday afternoon into Sunday. By this time, the prior wave will have pushed the surface cold front SE through most of the region; this means buoyancy will be neigh available and lightning potential will be low (let alone any severe threat). As the upper trough axis inches near the region late in the day, the precipitation line will shift east of the area as dry slotting begins to erode clouds west to east.
Still plenty of moisture in place today, which combined with more sunshine/instability and perhaps a couple of ill-defined disturbances within the weak 700-500 mb troughiness across the region will result in an uptick in coverage of showers and thunderstorms today compared to yesterday. The HREF and UofA WRF guidance is tending to focus the highest thunderstorm chances both across the higher terrain and also for locales south of Tucson, centered over Santa Cruz/South Central Pima County and this seems reasonable. A gradual drying trend will commence Sunday, especially aloft as ridging also builds in.
- A warming trend develops Sunday with warmer temperatures to remain the remainder of the week.
Lows are expected to fall into the low to mid 30s across much of the area. Temperatures continue to vary across northwest MN, with a few locations dropping to the lower 30s earlier but others already increasing as low clouds fill in. Large scale mid/upper troughing associated with the Hudson Bay low remains in place, with northerly flow over our region. The Hudson Bay low begins to break down allowing for mid level ridging to build east.
The weather pattern above the US will start out with a long wave trough to the east with a weak ridge to the west. As time progresses, the trough should push eastward into the Atlantic Ocean with the ridge building and moving over the Plains by mid week.
541 AM CDT Sat Sep 6 2025 -A much cooler day is in store for the Natural State as the cold front has nearly completely the journey from north to south across the state. -High temperatures on Saturday will range statewide from the low 70s to the low 80s.
Largely seasonable weather this weekend transitions to a cooler and more active weather pattern moving into the week ahead as a slow moving weather system impacts the region.
Current water vapor imagery shows and expansive trough digging into the eastern CONUS, with flow over the Middle Mississippi Valley becoming increasingly northwesterly. This flow is spreading an expansive area of high pressure at the surface across the Plains and into the Midwest.
1233 PM CDT Sat Sep 6 2025 - Cooler than normal again today, with a chance for patchy frost tonight in central MN.
