1152 PM CDT Sun Jun 9 2024 (Tonight through Tuesday night) High pressure ridge overtop the region is holding on by a thread, per latest 500 mb analysis. Digging trof over the Great Lakes Region is working on this high, and it will continue to do so overnight. High pressure gets shunted to the east as a cold front meanders down into Louisiana during daylight hours Monday. This should result in some slightly cooler daytime temperatures as well as lower Heat Indices Monday and Tuesday.
1148 PM CDT Sun Jun 9 2024 - Nice weather continues for Monday with highs in the lower 80s, light winds, and ample sunshine.
Though decreasing in coverage, an upper disturbance embedded within the upper high that is overhead will help to sustain convection through the rest of the night. Cloud cover will help to keep highs on the cool side today ranging from the low 70s to low 80s.
223 AM EDT Mon Jun 10 2024 Mostly dry and cooler weather is expected today and tonight.
Cooler and drier air was sloly advecting into the state fm the north. Highs today and Tue will range fm the upper 70s to the lower 80s, with nighttime lows in the mid 50s to the lower 60s.
347 AM EDT Mon Jun 10 2024 A supporting mid-level trough of low pressure will push across the region today. High pressure will build over the area tonight through midweek, leading to dry conditions. A mid-level trough of low pressure and associated upper level jet streak will move across the region today. Dry conditions will ensue tonight with high pressure building into the region from the west. Lows tonight will be in the middle 40s in the western mountains to the lower 60s along the Chesapeake Bay.
211 AM EDT Mon Jun 10 2024 A cold front will continue to drop south and east bringing scattered showers and storms as well as ending the heat today. 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. A weak wave of low pressure should turn low level winds offshore Tuesday allowing for dry air to advect in from the NW, aided further by the mid level trough axis swinging through.
128 AM EDT Mon Jun 10 2024 A cold front will move southeast through the area late today.
/19/ (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. Highs tomorrow will be limited by the additional cloud cover as well, with highs only getting up into the low to upper-80s. Lows tonight will still hover in the mid-70s, before dropping behind the front tomorrow into the low to upper-60s.
Sfc cold front is near the Western Kentucky and Bluegrass Parkways as of 18Z, and slowly but surely making its way southward through the Commonwealth. Could continue to see scattered showers across southern Kentucky until around sunset, after which the cold front should be far enough south to keep any additional precip down across the Tennessee Valley. Northerly flow ahead of building high pressure will be just enough to advect dry low-level air into the Ohio Valley tonight. Cool pattern continues on Monday with another vort lobe swinging through the broad eastern CONUS upper trof. Upper flow aloft will become more zonal for the mid-week after an East Coast trough pushes out to sea.
Looking ahead, surface ridging builds in from the north today and tomorrow keeping skies clear through Monday. Temperatures will remian pleasant topping out in the low to mid 80s with lows dipping into the 50s. By Tuesday, the 850mb ridge will slide to the east of the area, returning flow back to the south and ushering moisture back into the region as temperatures top out in the mid to upper 80s. A long wave trough moving through the northern Plains during the day should push a weak frontal boundary through Nebraska, potentially making its way south into Kansas. For the remainder of the week, mid-level heights increase, promoting warmer temperatures.
334 AM CDT Mon Jun 10 2024 - Nice weather continues with highs in the lower 80s, light winds, and ample sunshine.
- Warmer and drier conditions expected Tuesday through most of the week. Further ahead, weak ridging to fairly zonal flow will take over.
1155 PM CDT Sun Jun 9 2024 (Tonight) Weak cold front has just about moved southward thru all of north AL this Sun evening. While most of the lingering showers/tstms have moved just south of the area, some additional light/moderate showers out of west/mid TN associated with an upper trough axis dropping southward thru the region is beginning to cross into NW AL. With the passage of the front, slightly cooler/drier air will filter into the area from the north, thereby allowing lows into early Mon to fall into the lower/mid 60s.
315 AM CDT Mon Jun 10 2024 - An upper trough and weak cool front will support thunderstorm development late this afternoon and evening.
(Today through Tuesday) This morning, the cold front is near a Demopolis to Alex City line and sliding south. Dry conditions areawide tonight and Tuesday as high pressure builds into the area.
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. (Monday through Tuesday night) Frontal trough is expected to sink south into southern GA during the day on Monday. Lows in the lower 70s. With the added cloud cover and rainfall, highs will be a little lower, generally in the lower 90s. Lows in the lower 70s.
220 AM EDT Mon Jun 10 2024 A cold front will move southeast through the area late today.
Values in the lower to middle 50s will filter southward today and remain in place through Tuesday.
1043 PM CDT Sun Jun 9 2024 (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.
333 AM EDT Mon Jun 10 2024 High pressure and cooler air settles in behind a weak front moving through the region this morning. The cool air mass is replaced by much warmer air as the high pressure shifts to the east through midweek.
A few sprinkles may linger over the higher terrain this evening, on the back side of an upper level trough.
High temperatures will be below normal in the wake of yesterday's cold front with mostly clear skies and dry conditions. (Tuesday Night through next Monday) As we head into the mid to late week period, temperatures will be warming each day as high pressure begins to build overhead.
1126 PM EDT Sun Jun 9 2024 - High pressure brings dry conditions for the first half of the week. This low level moisture is residing under a post frontal inversion. 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.
Temperatures are in the lower 80s and dew points are in the upper 70s, so still pretty muggy even at this early hour.
As for temperatures, highs will be somewhat tempered by the clouds/ diurnal storms, with readings likely in the lower 90s for today and tomorrow. Overnight lows will range from the lower to mid 70s for a good part of the CWA.
An upper trough gradually departing the area Tuesday can lead to a couple of showers popping up in the afternoon over the Catskills and Poconos, otherwise, it will be a quiet day with some sunshine. Lows will be from the mid 40s to the low 50s at night.
We will have a broad cyclonic flow in the mid and upper levels, and with cooler temperatures aloft with this trough, northern sections will have some scattered cloud cover. Showers with this trough should stay north of our area in WV.
There will be thunderstorm chances overnight as a cold front slowly moves north to south over the area. The national flow pattern amplifies on Monday with longwave troughing over the Tennessee Valley extending northeast toward the upper low located just northeast of Maine while ridging builds over much of the Plains. The surface cold front will continue to advance south toward the Gulf Coast through the day. High temperatures will range from the low 80s far north and in the higher elevations east to readings around 90 across the far southeast counties.
1223 AM CDT Mon Jun 10 2024 - The entrance of a high pressure combined with clear skies will cause temperatures to drop quickly overnight.
Mid-level ridging continues to hold on for a bit longer across the Florida peninsula. This ridge will continue to breakdown over the next 24 hours. Expect this ridge and dry air aloft will keep precipitation coverage limited later this afternoon. Highs will climb into the low to mid 90s with heat indices in the upper 90s to lower 100s. The mid-level ridge will breakdown and a 300 mb subtropical jet streak will move across the Gulf of Mexico. High temperatures will be on the cooler side in this wet pattern.
212 AM EDT Mon Jun 10 2024 Cold front today with scattered showers.
A weak, flat ridge building over the region today will allow temperatures to creep back up above average for this time of year. The flat ridge will flex a little the next several days giving way to zonal (straight west-to-east) flow. Models all agree on a trough of some kind dropping out of the northwest, but there's a lot of difference in the timing and how much moisture comes with it. A weak, flat ridge building over the region today will cause IFR conditions.
302 AM EDT Mon Jun 10 2024 Low pressure across the north will slowly move away to the northeast today through Tuesday.
1244 AM CDT Mon Jun 10 2024 (This evening through Tuesday) Unpleasant conditions remain in place at the sfc across much of the state ahead of an approaching cold front. By Monday morning the cold front should have progressed south of the area with precip coming to an end as sfc ridging builds in.
230 AM EDT Mon Jun 10 2024 Somewhat unsettled daytime weather is expected to continue into Tuesday as upper level low pressure lingers overhead.
- With elevated wind speeds and gusts with the passing cold front, a Lake Wind Advisory is out through 9 PM this evening.
647 AM EDT Mon Jun 10 2024 High pressure and cooler air settles in behind a weak front moving through the region this morning. The cool air mass is replaced by much warmer air as the high pressure shifts to the east through midweek.
643 AM CDT Mon Jun 10 2024 Today and Tonight: As a weak cold front continues southward today, the most noticeable difference will be drier air spreading southward by the afternoon and evening. For areas south of Interstate 20, it will still be a fairly hot day with afternoon highs in the lower 90s and heat index values approaching 100 in some areas. For areas north of the Interstate, the slightly cooler and drier air should see those heat index values cap out around 85-90 degrees. Pooled moisture and instability along the cold front will also support better precip chances closer to the Gulf Coast under daytime heating, though an isolated shower or storm can't be ruled out elsewhere in the area.
613 AM CDT Mon Jun 10 2024 - Nice weather continues with highs in the lower 80s, light winds, and ample sunshine.
627 AM CDT Mon Jun 10 2024 - An upper trough and weak cool front will support thunderstorm development late this afternoon and evening.
* Temperatures will be on the rise through the end of the week as high pressure brings a stretch of rain- free weather with relatively low humidity, light winds, and plenty of sunshine. Lows will range from the mid 40s across the Allegheny Plateau to the mid 50s in the Lower Susquehanna Valley. The upper trough that has kept temperatures below normal will be slow to exit the region on Tuesday. North or northwest winds will continue to promote cold air advection, but the lack of as much cold air aloft should result in fewer clouds and therefore allow temperatures to trend 3 to 6 degrees warmer across higher elevations Tuesday afternoon. High pressure will begin to build in Tuesday night, which will support clearing skies and calm winds.
High pressure then begins to build over Arizona, leading to hot temperatures across the region for the middle of the week.
Upper level ridging returns over the region today and a thermal trough redevelops along the coast. These clouds will give way to sun by late morning and inland temperatures will trend warmer today by a few degrees, reaching about 10 degrees above normal.
Broad and flat 500mb ridging will build over the area from the west today providing much warmer max temperatures for the interior.
Temperatures will be considerably cooler today, with highs ranging from the low to mid 80s north of the front across the Big Country, to the upper 80s to near 90 south of the front.
636 AM CDT Mon Jun 10 2024 (Today through Tuesday) This morning, the cold front is near a Demopolis to Alex City line and sliding south. Dry conditions areawide tonight and Tuesday as high pressure builds into the area.
636 AM EDT Mon Jun 10 2024 Somewhat unsettled daytime weather is expected to continue into Tuesday as upper level low pressure lingers overhead.

This will result in dry weather and slightly cooler temperatures today, with afternoon highs limited to the low to mid 80s.
High pressure will begin to build over the region today and persist through much of the week. A cold front will move through the region by the end of the week. A large and deep upper level trough has developed across the Great Lakes region and the Northeast CONUS this morning. A secondary cold front has also pushed through the area overnight. High pressure centered northwest of the Upper Great Lakes region will build southward across our area today. High temperatures will range from the upper 50s over NWPA and the lower 60s over NEOH. High pressure will build over the Ohio Valley region tonight with clearing skies. Areas near the lake will be in the lower 50s. Warming temperatures and mostly quiet weather will be the story through mid week as high pressure remains overhead much of the Eastern CONUS.
925 AM EDT Mon Jun 10 2024 High pressure and cooler air settles in behind a weak front moving through the region this morning. The cool air mass is replaced by much warmer air as the high pressure shifts to the east through midweek.
604 AM EDT Mon Jun 10 2024 Cold front today with scattered showers.
444 AM CDT Mon Jun 10 2024 Today and Tonight: As a weak cold front continues southward today, the most noticeable difference will be drier air spreading southward by the afternoon and evening. For areas south of Interstate 20, it will still be a fairly hot day with afternoon highs in the lower 90s and heat index values approaching 100 in some areas. For areas north of the Interstate, the slightly cooler and drier air should see those heat index values cap out around 85-90 degrees. Pooled moisture and instability along the cold front will also support better precip chances closer to the Gulf Coast under daytime heating, though an isolated shower or storm can't be ruled out elsewhere in the area.
245 PM EDT Mon Jun 10 2024 (This afternoon through Tuesday) Cold front continues to slowly traverse the CWA today. Deep trough is in place across the eastern CONUS with notable speed max over east central GA into SC. Day time heating has brought temperatures well into the upper 80s and lower 90s across this area with dewpoints that are in the lower 70s. Upper level trough has brought moderately cooler temps aloft, allowing lapse rate to increase to 7 C/km.
1226 PM CDT Mon Jun 10 2024 - Nice weather continues with highs in the lower 80s, light winds, and ample sunshine.
This will bring a slightly cooler and drier air mass into our area for tonight and tomorrow. Lows tonight will be in the low to mid 50s with even a couple spots touching the upper 40s on the Upper Cumberland Plateau.
- Elevated wind speeds and gusts behind the cold front that passed earlier has warranted the Lake Wind Advisory to continue through 9 PM this evening.
A plume of deep tropical moisture will be lifting up over the area overnight and Tuesday and align along a stalled frontal boundary in place across south Florida and a weak upper trough. The trough axis shifts west for the weekend, but enough moisture will remain to allow for scattered to numerous storms still.
Unseasonably mild and dry air continues to filter into the Ohio Valley this afternoon as a reinforcing cold front has just dropped south of the Ohio River. Afternoon highs close to persistence across southern Kentucky, perhaps a couple degrees warmer with more sunshine in southern Indiana and north central Kentucky.
While the ridgetops near the Continental Divide have a 50 to 70% of wind gusts greater than 50 mph.
230 PM EDT Mon Jun 10 2024 High pressure currently over the northern Plains will slide southeast through the week, keeping dry weather across the region.
Highs will max out in the low to mid 80s with dew points in the 50s to 60s.
The troughs are squashing the ridge that was to build into the region this week, and has kept the temperatures lower the last two days, and even kept the humidity down a bit. The earlier convection helped to over turn the lower atmosphere in most of the forecast area.
Another weak wave will slide across the northwest side of the ridge by the weekend, but impacts likely to remain north and west.
319 PM EDT Mon Jun 10 2024 - Chilly and dry again tonight with high pressure overhead.
(Tonight) A cold front passing last night has allowed for the weather to clear in its wake. Conditions remain pleasant and dry throughout the day as a ridge continues to build across the central US and an upper level trough moves east off the Atlantic coast. Highs should primarily be in the low to mid-80s this afternoon, with lower humidity and wall-to-wall sunshine.
150 PM EDT Mon Jun 10 2024 High pressure currently over the northern Plains will slide southeast through the week, keeping dry weather across the region.

1151 AM EDT Mon Jun 10 2024 Cold front today with isolated showers and storms.
As we get a little later in the afternoon and a little warmer, a few of the storms may pulse up and produce some marginally severe hail. Weak upper low continues to spin across Eastern New Mexico and this is expected to drift southeast into the area tonight. By Tuesday afternoon, portions of West Central Texas south of the low may be unstable enough to generate a few stronger storms that may eventually form into another southeast moving MCS and roll into the Hill Country.
(Tonight and Tuesday) Troughing over the Mid-Atlantic and Northeast states has our area under a cool northwesterly flow and fair weather, including comfortable temps running maybe 3-5 degrees below normal tonight and Tuesday. High pressure begins to build to our west Tuesday, not close enough to impact our temps just yet.
110 PM EDT Mon Jun 10 2024 High pressure and cooler air settles in behind a weak front moving through the region this morning. The cool air mass is replaced by much warmer air as the high pressure shifts to the east through midweek.
Tuesday will be dry as upper level ridging builds over the region and precip water values fall to around 1 inch inland to 1. Heat index values should not an issue on Tuesday due to the lower dewpoints.
330 PM EDT Mon Jun 10 2024 High pressure currently over the northern Plains will slide southeast through the week, keeping dry weather across the region.
(This evening through Tuesday night) Upper trough extended from Maine to the Lower Ohio River Valley this afternoon, with upper lows over New Mexico and off the Baja California coast. Scattered showers and a few thunderstorms dotted the area, with somewhat better areal coverage over the lower portions of the coastal parishes. Dew points were in the low to mid 70s near and south of the frontal boundary, but seeing dew points fall into the upper 60s across southwest Mississippi. The upper trough to our northeast should help the surface boundary off the coast. Won't depart significantly from the NBM deterministic temperature forecast, which is pretty much a compromise on minimum temperatures, and on the warmer end for highs.
140 PM EDT Mon Jun 10 2024 High pressure and cooler air settles in through Tuesday night. The cool air mass is replaced by much warmer air as the high pressure shifts to the east through midweek.
220 PM EDT Mon Jun 10 2024 Cold front today with isolated showers and storms.
