822 PM EDT Sat Jun 25 2022 High pressure should allow for a mostly dry forecast to continue through the weekend.
737 PM EDT Sat Jun 25 2022 Weak high pressure overhead will slide east and help to transport warmer air in from the south this afternoon and increase the humidity for Sunday.
A fair amount of cloud cover continues to rotate into ND on the backside of the upper low. However, will keep it as just showers for now, due to the low likelihood of much thunder. Sunday highs should be a little warmer to the west of the Red River Valley, and a little cooler to the east, where there will be more clouds.
900 PM EDT Sat Jun 25 2022 Upper level ridging will remain over the region tonight into early Sunday.
701 PM EDT Sat Jun 25 2022 A few light sprinkles or showers for the western half of the CWA this afternoon before a weak cold front brings a chance for a few more rain showers and perhaps a few embedded thunderstorms overnight.
1030 PM EDT Sat Jun 25 2022 Frontal trough is draped across our southern counties extending into the Atlc which is providing enough low level convergence to produce scattered showers and storms across Martin/St Lucie counties.
A cold front will drop south into the state late tonight into early Sun morning.
1000 PM EDT Sat Jun 25 2022 High pressure centered off the Mid Atlantic coast will provide a dry weekend with seasonably warm temperatures.
935 PM CDT Sat Jun 25 2022 (Issued 917 PM CDT Sat Jun 25 2022) Thanks to the persistent cloud cover and shower/drizzle activity, today ended up staying much cooler. However, the cooler trend will continue for Sunday as a cold front is currently working its way into southern WI.
832 PM EDT Sat Jun 25 2022 High pressure centered off the Mid Atlantic coast will provide a dry weekend with seasonably warm temperatures.
630 PM EDT Sat Jun 25 2022 High pressure ridges in from the north through the weekend.
The main updates to the going forecast involve the POP and Wx forecast, with significant reductions to POPs through 10Z and more modest reductions into the low to mid chance range from 10 to 12Z. (Tomorrow through Saturday) Expansive post frontal cloud cover along with scattered showers and storms will keeps highs notably cooler Sunday compared to recent days.
631 PM CDT Sat Jun 25 2022 Much quieter conditions will continue through the short term as high pressure builds south out of Canada into the Great Plains. Cold air advection into the region as the high builds south will bring some cooler 850 mb temperatures (10 C to 14 C) to north central Nebraska.
1002 PM EDT Sat Jun 25 2022 High pressure moves off the coast tonight.
Cold front beginning to push into our nw cwa with plenty of warm/moist airmass ahead of the front. Late this afternoon and tonight: Cold front will continue to progress southeast across the cwa. In the wake of the front cooler and drier air arrives on fresh northwest winds. Sunday: Upper trough digging southeast across the upper Midwest and Great Lakes region will send a delightful cooler and much less humid airmass across our area.
522 PM EDT Sat Jun 25 2022 Weak high pressure overhead will slide east and help to transport warmer air in from the south this afternoon and increase the humidity for Sunday.
637 PM CDT Sat Jun 25 2022 Key Messages: - Cold front with accompanying scattered storms sweeps through this afternoon and evening.
924 PM EDT Sat Jun 25 2022 High pressure should allow for a mostly dry forecast to continue through the weekend.
742 PM EDT Sat Jun 25 2022 Dry and warm weather is expected tonight under high pressure. Shower and thunderstorm chances return with a Sunday cold front.
Some moisture may try to work north/east along an inverted trough that is currently stretching from eastern Colorado into southwest Kansas. The cold front from this morning has made it through the CWA as cooler air in the 70s to low 80s are overspread across the area with widespread overcast skies. Sunday, confidence has increased in cooler temperatures across the area. For this forecast package went with a blend of the MEX/MET guidance for the high temperatures as they appear to be handling the potential for cooler temperatures the best. High temperatures are currently forecasted to be in the low 60s across the SW portions of the area to the mid 70s across the east.
627 PM CDT Sat Jun 25 2022 Cold front has traversed east across the forecast area today (located just east of Storm Lake, IA as of 2 PM CDT/19z). Mostly clear skies continue tonight, and with a secondary push of CAA as upper low swings across southern Canada, expect temperatures to remain on the cooler side. Expect lows in the lower to mid 50s. Cooler for Sunday with northwesterly flow and CAA in place aloft. Again, did drop highs a degree or two from the previous forecast, in the low to upper 70s. Gusts tomorrow could reach 30 mph, but should taper off during the late evening as mixing decreases and high pressure builds in.
613 PM CDT Sat Jun 25 2022 Summary: A cold front accompanied with rain showers continues to move across northeastern Minnesota into northwestern Wisconsin. The cold front moving through the Northland this afternoon is bringing scattered showers through the area.
651 PM CDT Sat Jun 25 2022 (This evening through Sunday) A weak inverted trough can be seen moving slowly northwest across the area this afternoon, while an upper level low is moving east through southern Canada. A cold front being pushed south by the Canadian low can be seen in satellite and radar imagery just north of the I-40 corridor in the TX panhandle, making slow progress to the south. Have included some Slight Chance Pops near and along the cold front for Sunday afternoon, as convergence along the front, along with ample instability and moisture should be enough to get at least some isolated to scattered storms going during the afternoon hours. For tonight, expect similar conditions to the last several days, lows mainly in the low to mid 70s, mostly clear skies, and south winds 5 to 15 mph.
629 PM CDT Sat Jun 25 2022 (Through tonight ) Ongoing hot and humid conditions will persist through early evening ahead of the approaching strong cold front. (Tomorrow through Saturday) Expansive post frontal cloud cover along with scattered showers and storms will keeps highs notably cooler Sunday compared to recent days.
459 PM MDT Sat Jun 25 2022 The cold front from this morning has made it through the CWA as cooler air in the 70s to low 80s are overspread across the area with widespread overcast skies. Sunday, confidence has increased in cooler temperatures across the area. For this forecast package went with a blend of the MEX/MET guidance for the high temperatures as they appear to be handling the potential for cooler temperatures the best. High temperatures are currently forecasted to be in the low 60s across the SW portions of the area to the mid 70s across the east.
After a long wait, the lower Keys cloud line finally activated just prior to sunset and created a couple thunderstorms south of Sugarloaf/Cudjoe Keys. The resultant outflow given the light northerly winds over the Lower Keys preserved several thin boundaries that continue to focus isolated showers oceanside at this time. closer to the 850-700 mb troughing continuing to drift slowly southward. The evening sounding was showing what the southward-drifting trough and its propensity for concentrating moisture intended to do. Light and variable winds were noted along the upper and middle Keys coastal waters, while nearing a maximum near the lower Keys out of the north at 5 to 10 knots.
/NF/ Tonight and tomorrow: Pesky upper ridging that has been parked over the Lower Mississippi Valley will finally begin to break down and retrograde into the Southern Plains. This will occur as a potent northern stream trough slides across the Northern Plains into the Great Lakes region. At the surface, a cold front will be dropping out of the Central Plains and is forecast to be draped across northern Arkansas into the Ohio River Valley. This will result in mild overnight temperatures with lows only falling into the low to mid 70s.
926 PM EDT Sat Jun 25 2022 High pressure ridges in from the north through the weekend.
452 PM MDT Sat Jun 25 2022 Update: Scattered showers with isolated thunder and gusty winds continue to track from north to south across NE Montana, supported from instability associated with the upper low centered off to the northeast. An upper ridge building over the Pacific NW will move in over the next several days allowing for subsidence, warming and mainly clear skies.
714 PM CDT Sat Jun 25 2022 Isolated showers and thundershowers have developed from eastern to southern MN along a cold front early this afternoon. This activity should remain weak as the cold front pushes east through MN. After the cold frontal passage, skies will mostly clear while surface winds prevail west- northwesterly. The flow will usher in much drier and cooler air to begin our upcoming week.
244 AM CDT Sun Jun 26 2022 Cooler and less humid air will filter into the region today, on gusty northwest winds. High pressure will settle over the region for the start of the work week, bringing quiet weather and temperatures a few degrees below normal. A cold front was pushing into western IL at 2 AM. Northwest winds will increase this morning as the MSLP gradient tightens behind the front, and ahead of surface ridging over the central Plains. Highs will be considerably cooler than recent days, near 80 for most areas though mid 80s south of I-70.
1224 AM CDT Sun Jun 26 2022 (This evening through Sunday) A weak inverted trough can be seen moving slowly northwest across the area this afternoon, while an upper level low is moving east through southern Canada. A cold front being pushed south by the Canadian low can be seen in satellite and radar imagery just north of the I-40 corridor in the TX panhandle, making slow progress to the south. Have included some Slight Chance Pops near and along the cold front for Sunday afternoon, as convergence along the front, along with ample instability and moisture should be enough to get at least some isolated to scattered storms going during the afternoon hours. For tonight, expect similar conditions to the last several days, lows mainly in the low to mid 70s, mostly clear skies, and south winds 5 to 15 mph.
259 AM CDT Sun Jun 26 2022 A cold front is working across the area ushering in dew points in the 50s while low clouds continue to move east exiting the area. A cooler and drier air mass is working into the area for today and tonight as the storm system which brought our rain continues moving east away from the area. Northwest flow is expected to begin the period before ridging builds in across the middle of the week. Towards the holiday weekend, guidance agrees that another cold front is expected to move into the area. A cold front will move through the area early in the period clearing out any developing fog early this morning.
246 AM MDT Sun Jun 26 2022 Current surface map places high pressure across eastern Montana into western South Dakota.
Sfc analysis indicates a trough feature along the SE FL waters and across the Treasure Cst. Storms should not be particularly strong with lightning, Locally heavy rainfall of two to three inches, and storm gusts of 35 to 45 mph possible mainly where the highest chc of storms exist.
200 AM EDT Sun Jun 26 2022 High pressure should allow for a mostly dry forecast to continue through the weekend.
(Today and tonight) An upper trough digging across the U. Northern Plains into the Upper Midwest will continue to push a cold front across the Southern Plains this morning.
350 AM EDT Sun Jun 26 2022 Upper air pattern consists of a 500 mb trough in the upper Great Lakes this morning which will pass through the area today. With the trough aloft over the area today, will be a slight chance for some instability showers and kept in the slight chance pops in for this afternoon over most of the area. A cold front in the U. As the comma head of the low attached to the cold front moves over the region Sunday, some light rain showers could be seen across the area in the afternoon into evening hours.
Composite analysis depicts a weak surface and low level trough lying across South Florida, with an upper level trough axis east of the Bahamas, and a deep subtropical ridge centered over the Lower Mississippi Valley. This pattern has resulted in a lack of any significant ridging or dry layers aloft over our region, as reflected by the 00Z Key West and Miami soundings, which measured above normal PWs of 1. However, with abundant moisture available, light flow allowing for mesoscale boundary interactions including the potential for island cloud line development, and the proximity of low level troughing, would expect scattered showers and storms to redevelop later today. This scenario is supported by much of the CAM guidance, as well as by the high PoPs from the numerical model guidance.
(Today through Sunday night) A cold front is located across north Texas and is forecast to move into the northern Big Country around sunrise, then the I-20 corridor by late morning, and finally reaching the I-10 corridor this evening.
105 AM EDT Sun Jun 26 2022 High pressure should allow for a mostly dry forecast to continue through the weekend.
240 AM CDT Sun Jun 26 2022 Key Messages: - Cool, less humid and breezy today - Rebounding temps through mid-week with storm chances Tue/Thur Today: Cool, breezy and less humid A much less humid and cooler Canadian airmass will continue to filter across the region today in the wake of the passing cold front. After a sunny start to the day, diurnal cumulus will increase beneath the mid-level cold pool as an upper trough swings across the Great Lakes, with higher coverage to the north. An isolated shower could not be completely ruled out across northern WI this afternoon closer to the upper trough/coldest mid-level temps. Cool overnight lows generally in the low 50s are on tap for tonight with a few locations in central/north-central WI falling into the low to mid 40s.
135 AM EDT Sun Jun 26 2022 Upper level ridging will remain over the region tonight into early Sunday.
1046 PM CDT Sat Jun 25 2022 Cold front has traversed east across the forecast area today (located just east of Storm Lake, IA as of 2 PM CDT/19z). Mostly clear skies continue tonight, and with a secondary push of CAA as upper low swings across southern Canada, expect temperatures to remain on the cooler side. Expect lows in the lower to mid 50s. Cooler for Sunday with northwesterly flow and CAA in place aloft. Again, did drop highs a degree or two from the previous forecast, in the low to upper 70s. Gusts tomorrow could reach 30 mph, but should taper off during the late evening as mixing decreases and high pressure builds in.
The upper air pattern involves high pressure over the south central United States and a ridge building over the western states, causing northwesterly flow aloft over Nebraska. Temperatures should be cooler today compared to yesterday with highs in the 70s.
The cold front will continue to move slowly southeast through the remainder of the forecast area during the morning today, taking the chance for showers and thunderstorms with it. Behind the cold front, dry, cold air advection will promote a distinct change in sensible weather from Saturday. 850 mb temperatures will begin to cool into the mid to lower teens, and the resulting surface temperatures will peak in the 80s, about 15 degrees cooler than yesterday. Overnight lows will likewise be cooler than normal, cooling into the upper 50s.
1020 PM MDT Sat Jun 25 2022 Cooler and quieter conditions are expected this weekend as ridging builds to our west, keeping a dry northwest flow over the area. The cold front that pushed through last night will keep high temperatures east of the Divide 10-15 degrees cooler this afternoon, with highs elsewhere right around normal. Sunday will be calmer, with moderating temperatures east of the Divide as ridging nudges in warmer air.
(06Z TAFS) VFR conditions are expected to continue though a cold front is currently pushing its way into the area, clearing HOB in the last half-hour, bringing gusty winds and a northerly shift.
The higher PWAT airmass and some training of storms also is resulting in very efficient heavy rainfall clusters. Otherwise, much cooler air will overspread the area today with high temperatures expected to remain below 80F.
1117 PM MDT Sat Jun 25 2022 Widely scattered convection has fired off the higher terrain already this afternoon. This lull will be short lived, however, as flow turns once again more southeasterly as a ridge of high pressure builds in over the Great Basin. With high pressure in place, the only source of lift for showers and storms will be the terrain itself, and this is where convection is expected to fire during the late morning or early afternoon hours.
A favorable radiational cooling setup should allow overnight temperatures to drop to around 50 degrees for most areas, but likely colder in the typical cooler spots across the southwest.
1027 PM CDT Sat Jun 25 2022 Key Messages: - Cold front with accompanying scattered storms sweeps through this afternoon and evening.
127 AM EDT Sun Jun 26 2022 Today will remain dry with afternoon high temperatures remaining in the low to mid 90's.
236 AM CDT Sun Jun 26 2022 Overview: Much cooler conditions return to the area today with highs in the mid 70s expected.
355 AM EDT Sun Jun 26 2022 Showers and thunderstorms return today and tonight with a cold front.
325 AM EDT Sun Jun 26 2022 Chance for showers and storms increases this afternoon and evening, ahead and along a cold front. High pressure for much of the work week. Diurnal heating and high low level moisture will contribute to unstable conditions resulting in strong convection this afternoon and evening ahead of the approaching cold front. Despite of expected clouds cover, temperatures this afternoon will remain above normal, generally in the upper 80s lowlands, ranging into the lower 70s higher elevations.
452 AM EDT Sun Jun 26 2022 Upper air pattern consists of a 500 mb trough in the upper Great Lakes this morning which will pass through the area today. With the trough aloft over the area today, will be a slight chance for some instability showers and kept in the slight chance pops in for this afternoon over most of the area. Troughing behind a cold front persists tonight over the north- central United States. Overnight temperatures could drop into the mid-40s late tonight under the cool 850 mb temps as the low center digs southward.
This will effectively end precipitation potential for the remainder of the day despite the surface extension of cold front tracking through MBS around 18Z, northwestern Metro Detroit around 21Z and through the remainder of the cwa by 00Z this evening. May raise highs a degree or two as deeper mixing this afternoon/lowering dewpoints should allow temperatures to warm compressionally right in advance of the cold front.
(Today and Tonight) The much anticipated cold front has made it into the region early this morning, currently sitting near the I-44 corridor. The main surge of cooler, drier air will lag a bit behind the wind shift. Unfortunately, it will still be another hot and muggy day south of I-40 with highs still in the low 90s to mid 90s near the Red River this afternoon. The mid level ridge that has been firmly in place over the area much of the last week is beginning to flatten and shift southward which will allow more scattered storm development over NE OK this morning. Chances appear low and isolated in this region with the mid and upper ridge still nearby.
Satellite water vapor analysis shows the upper ridge centered over Arklatex and a potential weak disturbance moving around the western extend of the high and helping to contribute to some of this scattered storm activity. Precipitation chances continue to linger across the west and north tonight into tomorrow morning as the high starts to shift westward and the flow aloft becomes westerly.
311 AM EDT Sun Jun 26 2022 Showers and thunderstorms return today and tonight with a cold front.

1056 PM CDT Sat Jun 25 2022 Isolated showers and thundershowers have developed from eastern to southern MN along a cold front early this afternoon. This activity should remain weak as the cold front pushes east through MN. After the cold frontal passage, skies will mostly clear while surface winds prevail west- northwesterly. The flow will usher in much drier and cooler air to begin our upcoming week.
1243 AM CDT Sun Jun 26 2022 Summary: A cold front accompanied with rain showers continues to move across northeastern Minnesota into northwestern Wisconsin. The cold front moving through the Northland this afternoon is bringing scattered showers through the area.
The surface cold front is just now pressing into northwest Illinois where dewpoints are falling into the low 60s, and this will eventually scour moisture out through the rest of the morning. In the meantime, dewpoints remain elevated (in the lower 70s) and clearing in the wake of a dense anvil canopy will facilitate the development of patchy fog through daybreak.
1136 PM CDT Sat Jun 25 2022 Much quieter conditions will continue through the short term as high pressure builds south out of Canada into the Great Plains. Cold air advection into the region as the high builds south will bring some cooler 850 mb temperatures (10 C to 14 C) to north central Nebraska.
Mid/upper-level flow becomes northwesterly over the region today as upper-level ridging and heat build to our west.
310 AM EDT Sun Jun 26 2022 High pressure centered off the Mid Atlantic coast will provide a dry weekend with seasonably warm temperatures.
(Today) The upper ridge that brought us the mostly sunny and hot weather for much of the previous week will flatten and sink further to the southwest today. Meanwhile, a sharp upper-trough pivoting from the Canadian prairies into the Great Lakes will send a weak cold front ESE from the Ohio Valley into the Tennessee Valley later today. Ahead of these storms, however, we can expect very warm/humid conditions to continue as highs will peak in the low to mid 90s (with a few upper 90s possible) and peak heat index values between 100 to 105 degrees in most locations.
409 AM EDT Sun Jun 26 2022 Upper air pattern consists of a 500 mb trough in the upper Great Lakes this morning which will pass through the area today. With the trough aloft over the area today, will be a slight chance for some instability showers and kept in the slight chance pops in for this afternoon over most of the area. A cold front in the U. As the comma head of the low attached to the cold front moves over the region Sunday, some light rain showers could be seen across the area in the afternoon into evening hours.
125 AM EDT Sun Jun 26 2022 High pressure will prevail through the weekend. A cold front will stall near the area during the middle of the week before dissipating later in the week. High pressure will prevail through Sunday night, although a weak coastal trough will edge closer to shore. Subsidence under the upper ridge and unseasonably low moisture will keep the area rain-free. High temperatures will be near normal, mainly around 90 into the lower 90s away from the immediate coast, with comfortable humidity levels.
1254 AM EDT Sun Jun 26 2022 Showers and thunderstorms return today and tonight with a cold front.
311 AM CDT Sun Jun 26 2022 The cold front has made it through all of the FA as of 2 AM except for Stonewall county.
