416 AM EDT Mon Jun 27 2022 Multiple rounds of showers and storms expected through the overnight with a cold front. New cold front crosses next the weekend. Rain showers and a few storms are currently moving east of the Ohio River and will continue to progress eastward through the area ahead of and along a cold front this morning. Precipitation is expected to exit the lowlands by mid morning, while showers may linger across the mountains for another couple of hours. Temperatures will be cooler than normal today, with highs expected to be in the upper 70s to low 80s across the lowlands, and mid 60s to 70s in the mountains. Overnight temperatures are projected to be in the low to mid 50s for the lowlands, and mid 40s to low 50s in the higher elevations.
400 AM CDT Mon Jun 27 2022 Today and Tonight: Early morning surface analysis had a cold front still northwest of our CWA with a 1026mb high centered over the central Plains. The cold front is expected to still be north of our southeast most counties by sunrise Tuesday. For today though, the presence of this cold front and daytime heating will lead to scattered to numerous storms developing along and south of the cold front. Cooler than normal morning lows are expected across our north with near normal morning lows expected central and south.
(Today) A few isolated showers are ongoing early this morning as a slowing cold front nears the area. An upper trough located over the eastern Great Lakes will continue to lift northeast today, causing the front to slow and eventually stall south of the Tennessee River. Cooler temperatures will feel like a relief today as highs top out in the mid to upper 80s with decreasing humidity.
Very weak H500 anti-cyclonic flow across central/east Texas extending north into the Panhandle will nudge up against a weak, progressive positive tilted trough moving across the central Plains. As the weak H500 high pressure further compresses later today, the area of showers and low topped thunderstorms should shift into the southern TX Panhandle. The main H500 high pressure system will build back across the Four Corners Region once again for tomorrow.
In the mid-levels a trough has slid into eastern Canada, and cool and dry air is advecting into the region from the resulting northwesterly.
Nonetheless, relief is here and the crowd goes wild! Behind this frontal boundary are much cooler temps with pretty low dew point temperatures for the summer.
A brief break in the warmer weather is expected over the next couple days as the upper level flow becomes northwesterly with CAA both aloft and the surface.
(Today and Tonight) Temps starting out in the low 60s this morning for most places, along with drier air will give way to a pleasant late June day this afternoon across the region. Otherwise, partly cloudy skies with highs in the low to mid 80s will rule the day.
237 AM MDT Mon Jun 27 2022 Today high pressure becomes centered over southern Nevada allowing for weak northwest flow over our region. Showers and storms will form across the higher terrain around mid day with the better chances in the southern and central mountains. Given the drier air in the lower levels gusty outflow winds look possible especially along and north of I-70. Tomorrow a low pressure system moves into the Pacific Northwest causing the high to shift southward. The westerly flow will also usher in a slightly warmer air mass into the region so highs come up by about 5 degrees from today.
126 AM EDT Mon Jun 27 2022 High pressure will move offshore tonight and Monday.
High pressure will bring partly cloudy skies, mild temperatures, and low humidity.
1229 AM CDT Mon Jun 27 2022 (The rest of tonight) The latest surface analysis indicates the cold front extends across central AR into nern TX, with high pressure centered over the Central Plains building southward into the area this evening.
1141 PM CDT Sun Jun 26 2022 (This evening through Monday) Late this afternoon, a cold front was moving southward through western and central Texas. Temperatures immediately behind the front were about the same as ahead (roughly in the mid 90s), but cooler conditions existed further north across the Panhandle and Oklahoma. This should be aided by weaknesses in the upper-level ridge as it begins to break down. Tomorrow the slightly cooler, but also more humid, airmass will have filtered into the area. As the ridge continues to weaken, this will enhance any storms that develop.
412 AM EDT Mon Jun 27 2022 A cold front will track through the area today with high pressure expected to settle in for the middle portion of the week. Another cold front is expected to cross the area at the end of the week. Sct-nmrs showers/t-storms are expected today as a cold front crosses the area. Clear and cool conditions are expected tonight as high pressure begins to build into the area.
A trough of low pressure over the Atlantic will slide west- northwestward today and bring a chance of showers and isolated thunderstorms. Winds will favor an east- northeast direction this morning and veer in the wake of the trough to east-southeast later this morning/early afternoon.
114 AM EDT Mon Jun 27 2022 A cold front will move east across the Great Lakes and Ohio Valley overnight. High pressure and a cooler and drier airmass will build into the region through Monday. Mid level trof to settle into the Great Lakes overnight into Monday. Scattered showers and embedded thunderstorms developed this afternoon in the moderate instability in the warm airmass ahead of the associated surface cold front. High pressure will build east into the region Monday through Monday night with a drier, cooler airmass settling into the area. Highs on Monday will be in the mid to the upper 70s with lows Monday night in the low to mid 50s.
500 AM MDT Mon Jun 27 2022 Today high pressure becomes centered over southern Nevada allowing for weak northwest flow over our region. Showers and storms will form across the higher terrain around mid day with the better chances in the southern and central mountains. Given the drier air in the lower levels gusty outflow winds look possible especially along and north of I-70. Tomorrow a low pressure system moves into the Pacific Northwest causing the high to shift southward. The westerly flow will also usher in a slightly warmer air mass into the region so highs come up by about 5 degrees from today.
603 AM EDT Mon Jun 27 2022 Cooler airmass in place today with expanding high pressure supporting dry conditions. Dynamic upper level trough complex over northern Ontario/near James Bay has resulted in tight northerly gradient flow over Southeast Michigan.
636 AM EDT Mon Jun 27 2022 Increasingly drier as high pressure builds into the area today into tonight. A cold front crosses next the weekend. Rain showers and a few storms are currently moving east of the Ohio River and will continue to progress eastward through the area ahead of and along a cold front this morning. Precipitation is expected to exit the lowlands by mid morning, while showers may linger across the mountains for another couple of hours. Temperatures will be cooler than normal today, with highs expected to be in the upper 70s to low 80s across the lowlands, and mid 60s to 70s in the mountains. Overnight temperatures are projected to be in the low to mid 50s for the lowlands, and mid 40s to low 50s in the higher elevations.
Large scale high pressure stretches from the Southwest U. In addition, the position of the ridge will result in a northeasterly steering flow which will help push storms south of the rim. The ridge axis slides east centering over Arizona on Tuesday. With the ridge axis overhead and likely less cloud cover across our northern zones, these areas will see warmer temperatures.
955 AM EDT Mon Jun 27 2022 A cold front will track through the area today with high pressure expected to settle in for the middle portion of the week. Another cold front is expected to cross the area at the end of the week. Clear and cool conditions are expected tonight as high pressure begins to build into the area.
619 AM CDT Mon Jun 27 2022 (Today and Tonight) Temps starting out in the low 60s this morning for most places, along with drier air will give way to a pleasant late June day this afternoon across the region. Otherwise, partly cloudy skies with highs in the low to mid 80s will rule the day.
651 AM EDT Mon Jun 27 2022 High pressure and a cooler and drier airmass will build into the region through Tuesday. High pressure shifts to the east through midweek, resulting in warming temperatures.
407 AM CDT Mon Jun 27 2022 (Issued 407 AM CDT Mon Jun 27 2022) Today and Tonight: Dry air will continue to move into Wisconsin today as high pressure builds into the Great Lakes Region. Temperatures will return to the 80s Tuesday afternoon ahead of an approaching cold front.
Temperatures have jumped into the low to mid 70s where clearing has already occurred while cloud cover along the higher terrain has kept the area a few degrees cooler. Light northerly winds will move in behind the departing front, and will usher dry and much cooler air into eastern Kentucky. This pleasant air mass will stay in place for the next couple of days, as a ridge of high pressure builds into the region. Cooler than normal temperatures are on tap today through Tuesday as well, with highs in the upper 70s and lower 80s and lows in the 50s expected. Through the early half of the period, an upper ridge axis expands out of the desert Southwest across the southern states, promoting subsidence and dry mid to upper levels.
/issued 401 AM CDT Mon Jun 27 2022/ Finally some relief from the heat as a cold front has moved through the region. After midweek, a weak ridge will build back across the area.
940 AM EDT Mon Jun 27 2022 High pressure and a cooler and drier airmass will build into the region through Tuesday. High pressure shifts to the east through midweek, resulting in warming temperatures.
The hottest regions further inland such as interior San Benito county are forecast to be in the low to mid 100s again today with heat risk in the "high" to "very high" category. Looking ahead, a change in the weather pattern is expected with an upper level trough still on track to make its way through the area.
The upper pattern this morning is defined by a trough of low pressure over northern Arizona extending into SW Arizona, and a lobe of high pressure that is slowly moving west through northeast Sonora Mexico. Look for storms to develop late this afternoon along and near the weakening trough axis across south-central Arizona. Storms activity will persist into the evening and expand east and northeast as the upper trough drifts east and opens up.
957 AM EDT Mon Jun 27 2022 A weak surface and low level trough extending from southern Florida to the Bahamas is inducing showers and thunderstorms over the Bahamas.
923 AM EDT Mon Jun 27 2022 Cold front exits the region this morning with high pressure moving in behind it. Dry and cooler conditions will then persist through mid week.
Isolated showers remain possible as a cold front entering northern Alabama will track southeastward through the afternoon. Look for refreshingly cooler temperatures as we only warm into the mid to upper 80s later today. Behind the cold front this afternoon and evening, skies clear and lower dew points will reduce humidity levels.
Upstream is a short wave trough and accompanied cold front moving southeast thru northern Manitoba and northeastern Saskatchewan. Another weak 500 mb short will move southeast behind the initial cold front into NE ND/nrn valley late tonight thru midday Tuesday bringing with it scattered showers. Cooler airmass behind it and instability low (less than 500 j/kg) so expect high based light rain showers.
349 AM MDT Mon Jun 27 2022 Anticipate a short-lived heatwave across the Northern Rockies today through Tuesday, as high pressure amplifies over the western US. Concurrent with the Tuesday thunderstorm activity, a cold front will pass across the region and cool temperatures back to near the seasonal average.
the forecast area is under northwest flow aloft as upper level high pressure builds over central Nevada today, sliding southeast into northwest Arizona tonight. High temperatures are expected to range from the lower 70s across Greeley and Wichita counties where cloud cover lasts longer to the lower to middle 80s along and north of the Kansas/Nebraska border. Low temperatures are expected to fall into the lower to middle 50s. It will be dry with high temperatures rebounding back into the lower to middle 90s.
401 AM CDT Mon Jun 27 2022 Finally some relief from the heat as a cold front has moved through the region. After midweek, a weak ridge will build back across the area.
517 AM MDT Mon Jun 27 2022 Current surface map places high pressure from the Dakotas into the central plains.
Surface analysis this morning reveals a cold front pushing through portions of Kentucky and Tennessee, with slightly cooler temperatures much drier air advecting in from the northwest in its wake. Dewpoints in southern Indiana have fallen into the mid/upper 50s, while locations just ahead of the front in south-central or eastern Kentucky still have dewpoints in the low 70s. Daytime highs will generally climb into the low 80s, with considerably lower dewpoints compared to previous days to make it feel much more comfortable outside. Overnight, high pressure will slowly drift eastward and settle over the Ohio Valley. Along with plenty of sunshine, our afternoon highs will once again be in the low 80s with comfortable dew points near 50 degrees.
/22/ Today and Tonight: Early morning surface analysis had a cold front still northwest of our CWA with a 1026mb high centered over the central Plains. The cold front is expected to still be north of our southeast most counties by sunrise Tuesday. For today though, the presence of this cold front and daytime heating will lead to scattered to numerous storms developing along and south of the cold front. Cooler than normal morning lows are expected across our north with near normal morning lows expected central and south.
Northwesterly flow aloft continues overhead as we remain between ridging across the western U. and a trough across the Great Lakes. At the surface, high pressure has moved overhead and is forecast to move southeast of the area by this afternoon. Latest CAM runs do develop some light QPF as the low-level jet strengthens and interacts with the front late tonight into early Tuesday morning across northeast Nebraska.
344 AM MDT Mon Jun 27 2022 An upper ridge will slide from the Pacific NW into Montana over the next few day. As the upper ridge axis passes into the Dakotas by late Tuesday, southwest flow aloft will bring Pacific moisture into the state.
408 AM CDT Mon Jun 27 2022 Summary: Warmer day in store for the Northland today with highs in the mid to upper 70s. A cold front is expected to drop south of the International Border early Tuesday morning bringing some scattered showers. MLCAPE looks to be in excess of 500 J/kg with bulk shear slightly on the low end around 35kts. One of large uncertainties with this current set up is just how unstable will the region get before the cold front punches through. Rain and storms are expected to move out of the region quickly Tuesday night with clearing skies on the backside of the cold front. Look for lows in the lower 40s across northern MN and mid 40s for NW WI.
603 AM CDT Mon Jun 27 2022 After a nice cool start to the day temperatures will be on the rise as the low levels warm. This southerly flow is also not expected to bring any moisture into the area, so humidity levels will again be on the lower side. Highs will generally be in the low to mid 80s. Tuesday will be another warm day but there are some hints that parts of mainly southwest MN may be a few degrees cooler. Not exactly significantly cooler but maybe highs closer to 80 vs mid 80s.
559 AM CDT Mon Jun 27 2022 (Today and tonight) Early this morning, a cold front is approaching the Interstate 10 corridor and is forecast to continue to slowly move south this morning. PoPs were mainly confined south of Interstate 20, with the highest chances across our southern counties. Slightly cooler temperatures are forecast today.
522 AM PDT Mon Jun 27 2022 High pressure will continue hot weather for inland areas early this week. Coastal areas will remain cooler with areas of night and morning low clouds and fog.
514 AM EDT Mon Jun 27 2022 A cold front will finish pushing through Central PA this morning. High pressure will then build into the area, brining much drier air.
The forecast starts out with an upper ridge building to our west, over the PACNW, and an upper trough over the Great Lakes region. Winds are expected to pick up this afternoon from the southwest as the high moves east and we get the impacts of return flow. This afternoon starts a warming trend as highs reach the low to mid-80s. Tuesday, high pressure continues to move to the east. The upper ridge will also push east, reaching the Inter Mountain West.
Periods of MVFR conditions are expected when showers pass, and until the passage of a cold front in the afternoon. Showers and a few thunderstorms associated with a cold front will cross the area this morning. Cooler temperatures and lower dewpoints today and tonight. Discussion: A cold front, marked by a dewpoint gradient, is located from eastern OH through central KY to northern Middle TN at the moment, with an area of convection just ahead of it in eastern KY and WV.
The low level winds are pretty light across the forecast area at this time. Models have upper ridging building north, to our west, today.
631 AM CDT Mon Jun 27 2022 (Today) A few isolated showers are ongoing early this morning as a slowing cold front nears the area. An upper trough located over the eastern Great Lakes will continue to lift northeast today, causing the front to slow and eventually stall south of the Tennessee River. Cooler temperatures will feel like a relief today as highs top out in the mid to upper 80s with decreasing humidity.
Monday and Tuesday Dry conditions are expected today and tomorrow as a ridge of high pressure dominates the weather. A trough will cross northern and central Nevada tomorrow bringing breezy southwesterly then westerly winds for the afternoon and evening hours.
and Tuesday High pressure will keep the area dry today and tonight, as temperatures warm with less windy conditions across the western Great Lakes region. This leads us into the afternoon when a cold front is expected to bring a second round of showers and thunderstorms through the area. Highs on Tuesday are expected to range from the lower to middle 70s across the north, with highs in the lower 80s across east- central Wisconsin away from Lake Michigan.
840 AM EDT Mon Jun 27 2022 Mostly sunny and quiet morning across the region with an east to southeast low level flow setting up around high pressure well out in the Atlantic Ocean.
Hot and dry weather will be the main weather feature for interior NorCal today as upper level ridging remains in control. Ensembles and clusters show an approaching trough that will flatten the ridge and progressively move it eastward.
622 AM EDT Mon Jun 27 2022 Upper air pattern consists of a 500 mb trough in the Great Lakes region this morning. This trough moves to the lower Great Lakes by 00z tonight. Southerly winds increase early tonight ahead of a more notable surface to 300 mb trough located over far northern Ontario by early Tuesday morning. The low, now centered over James Bay, continues to deepen through Tuesday mid- day as shower and thunderstorm chances increase from northwest to southeast Tuesday afternoon and evening over Upper Michigan. Locally heavy rainfall up to 1" under the strongest thunderstorms is possible as storms form along and ahead of the cold front. Dry conditions return to Upper Michigan by early Tuesday night as the mid and upper level trough shift out of the north-central U.
646 AM EDT Mon Jun 27 2022 Cold front exits the region this morning with high pressure moving in behind it. Dry and cooler conditions will then persist through mid week.
650 AM CDT Mon Jun 27 2022 Summary: Warmer day in store for the Northland today with highs in the mid to upper 70s. A cold front is expected to drop south of the International Border early Tuesday morning bringing some scattered showers. MLCAPE looks to be in excess of 500 J/kg with bulk shear slightly on the low end around 35kts. One of large uncertainties with this current set up is just how unstable will the region get before the cold front punches through. Rain and storms are expected to move out of the region quickly Tuesday night with clearing skies on the backside of the cold front. Look for lows in the lower 40s across northern MN and mid 40s for NW WI.
340 PM EDT Mon Jun 27 2022 A weak cold front is oriented northeast to southwest from the western Carolinas through north Georgia into central Alabama.
Dynamic upper level trough complex over northern Ontario/near James Bay has resulted in tight northerly gradient flow over Southeast Michigan.
241 PM MDT Mon Jun 27 2022 Upper level ridge axis moves past the area tomorrow keeping our temperatures above average again. By tomorrow evening the next Pacific trough sends a cold front across Montana.
High pressure will be the dominant weather feature to start the work week.
239 PM MDT Mon Jun 27 2022 Temperatures will peak slightly above normal today as the ridge nudges further east. Relative humidity values will bottom out in the lower teens this afternoon, especially across southern areas. On Tuesday the ridge will be flattened a bit as a low moves into the Pacific Northwest. Otherwise, temperatures will further increase, generally into the low 90s east and upper 80s south.
There may be enough forcing to generate some cumulus towers and perhaps an isolated shower north of highway 2 mainly toward the NE/SD border, but expect the better chances for precipitation will reside off to the north across the Dakotas and also to our west associated with a surface trof, so generally expect dry conditions will prevail through tonight.
The front will lose its forward momentum as the parent trough pulls further away towards the Northeast, and the surface boundary will be left to provide some focus for showers and thunderstorms through tomorrow. PoPs may be maximized across our southern half of the forecast area as an inverted trough moves westward along the northern Gulf of Mexico.
1135 AM MDT Mon Jun 27 2022 Satellite shows just a few shallow cumulus clouds across the higher terrain this morning with mostly clear skies elsewhere. The low level winds are pretty light across the forecast area at this time. Models have upper ridging building north, to our west, today.
329 PM CDT Mon Jun 27 2022 A milder and relatively less humid airmass remains in place today after a cold front pushed through the area early yesterday. Lows tonight should be similar to or a couple degrees warmer than what we observed last night, with mid 50s in most locations and lower 60s toward downtown Chicago and the lake. A bit more warmth returns for Tuesday with highs in the lower to mid 80s. Dewpoints also make a recovery into the mid to upper 50s by late in the day, though the moisture has a long way to travel around the western edge of a sprawling ridge to our south before reaching northern IL and southern WI. Lenning The period begins on a dry note as a mid-level ridge begins to build into the area.
The forecast is generally on track with a cold front moving slowly southeast across the forecast area. /EC/ Prior discussion below: Today and Tonight: Early morning surface analysis had a cold front still northwest of our CWA with a 1026mb high centered over the central Plains. The cold front is expected to still be north of our southeast most counties by sunrise Tuesday. For today though, the presence of this cold front and daytime heating will lead to scattered to numerous storms developing along and south of the cold front. Cooler than normal morning lows are expected across our north with near normal morning lows expected central and south.
