Early this morning a frontal boundary extended from northeast Iowa into west central Kansas at 07Z with high pressure building in behind the front. Highs today will be cooler in the upper 80s to lower 90s behind the front. The medium to extended range forecast will be dominated by a stout summertime ridge over the southwestern U. The effects of this ridge will be felt over northeast Kansas in the form of hot and humid weather interspersed with low chances for showers and storms.
/issued 411 AM CDT Fri Jul 7 2017/ A near persistent upper low that has brought showers and thunderstorms to the Midsouth over the past several days had weakened into an open wave and dropped south into north MS early this morning. Rain chances to the north of this upper trof axis will remain limited today. A few isolated storms can't be ruled out nearer to the midlevel trof axis over north MS this afternoon. The overall pattern of a ridge in the western U.
203 PM CDT Fri Jul 7 2017 A brief dry period currently lingers across the mid state before a cold front moves through the area tonight.
235 PM EDT Fri Jul 7 2017 A cold front will cross through the region Saturday morning.
Upper ridge continues to dominate the weather pattern with hot and mainly dry weather. With the ridge axis moving over the area, expect very hot temperatures Saturday, with temperatures ranging from the mid 90s to the mid 100s.
This heated and moistened airmass is in place ahead of approaching cold front, seen by wind shift extending across ncntl IL. Dew points should be falling into the low to mid 60s, and more or less staying there, thru the remainder of the weekend.
Bowman radar shows scattered showers along the warm front. High pressure will slide off to the east Saturday and warm air advection will kick in across western North Dakota.
Upper high centered over the 4 corners area this morning with monsoonal moisture being pulled north into Arizona and Utah.
A lee-side trough remains just north of us. More isolated convection will occur across our northwestern zones ahead of the trough.
257 PM EDT Fri Jul 7 2017 A cold front moving through the region this evening will trigger showers and thunderstorms. Saturday will be cooler and breezy with scattered showers and perhaps a rumble of thunder.
Through the weekend, energy ejecting from a strong Gulf of Alaska low will impact the high amplitude ridge downstream across Rockies. This will effectively flattening the four-corners ridge enough to shift the upper flow to a more north-northwesterly direction for the Panhandle and South Plains.
348 PM EDT Fri Jul 7 2017 Showers and thunderstorms mainly south of Route 30 will come to an end early this evening as a cold front shifts southward.
1147 AM MDT Fri Jul 7 2017 Little change in store for today as high pressure continues to sit over the Four Corners. The center of high pressure is still on track to shift slightly west today.
Slightly lower humidity under the high will allow heat indices to mirror the seasonable air temperatures in the upper 80s to lower 90s this weekend, then return flow on the back side of the departing high will allow moisture to creep back into the region for the beginning of the week. Upper-level ridging currently centered over the Rockies will bulge and shift eastward with time, allowing the low-level thermal axis to pivot across the central and eventually eastern Plains this week. There remains some difference in the strength of the upper ridge as it translates eastward, but overall the pattern looks supportive of above normal temperatures in the lower to mid 90s, and southerly low-level flow will provide a continuous stream Gulf moisture and surface dewpoints (and lows) in the lower to mid 70s.
It will be continued quite warm over the weekend with an upper high centered over Utah and the CWA under northwesterly flow aloft on its front side.
231 PM PDT Fri Jul 7 2017 Temperatures will heat up through the weekend as a ridge of high pressure strengthens. Ridge of high pressure remains locked in over the Four Corners, with temperatures across our area near 10 degrees above average for this time of year. We could see a few buildups into the Highway 50 corridor late this afternoon and into the evening, although the main activity will remain south.
133 PM EDT Fri Jul 7 2017 A cold front will bring showers and storms today and tonight, some of which may be strong or severe. High pressure will build in the wake of the cold front keeping the majority of the weekend dry.
This should allow a backdoor cold front to approach the region during the day.
Strengthening high pressure aloft across the Great Basin will bring a gradual drying trend with seasonally warm temperatures across the region throughout the week.
645 AM EDT Mon Jul 31 2017 High pressure over the western Ohio Valley will build south and east into the Mid Atlantic through mid week. A stationary front stretching from Florida northeastward to just off the Southeast coast, will linger through the week, with areas of low pressure traveling up along the front. A strong cold front will move into the area late in the work week. Fair weather with below seasonable temperatures are expected today and tonight with high pressure continuing to exert its influence. A dry and subsident atmosphere will result in 0% PoPs through tonight with the just a couple of showers possible across the highest elevations of northwestern NC, western VA and WV and off the Carolina coast.
510 AM CDT Mon Jul 31 2017 A rather nice change to the weather this morning as the latest cool front has dropped temperatures into the lower 70s and the dew points into the upper 60s.
148 AM EDT Mon Jul 31 2017 High pressure will maintain dry and seasonable weather through early this week.
Upper ridge is still expected to retreat westward allowing a large broad trof to take shape over the eastern half of the country. High pressure lingering over the northern MS river valley will help keep these generally light E/NE winds in the forecast through at least late Tue. As the high moves off further east. Otherwise a series of weak upper level disturbances moving in from NW during the remainder of the week and then a possible cold front approaching this upcoming weekend will help produce periods of un- settled weather across the marine waters these next several days. 41 Generally VFR conditions expected as light NE winds prevail in the wake of the cold front.
144 AM PDT Mon Jul 31 2017 Intensifying high pressure will bring hot temperatures to the region this week with record breaking heat.
/Nisbet 06Z TAFS: High pressure aloft to deliver clear skies and dry conditions.
1130 PM MDT Sun Jul 30 2017 A large scale high pressure ridge aloft will gradually shift west as a series of alberta clippers moving down the east side of the ridge bring cooler air south in northwest flow. There will be enough moisture rotating up the west side of the ridge, then drifting east across Wyoming with marginal instability producing scattered showers and isolated thunderstorms, most numerous over the northern and western mountains.
539 AM EDT Mon Jul 31 2017 High pressure will maintain dry and seasonable weather through early this week.
550 AM EDT Mon Jul 31 2017 The low pressure over the Gulf waters continue to strengthen in the early morning hours. NHC has updated this low to Tropical Depression 6 at this time. The unseasonal cold front associated with the upper trough remains stationary over north and central FL with a decent plume of moisture ahead of it stretching across the peninsula. In addition to this feature, the National Hurricane Center is monitoring an area of low pressure over the north central portion of the Gulf which could have the potential for tropical development today. The low to mid level flow is from west to east which will allow for thunderstorms development in the west coast to travel eastward today.
High pressure will linger just south of the area today and tonight. Highs should rise into the lower 80s, despite some clouds sliding southeast through the area at times. Lake breeze should bring cooler temperatures this afternoon near Lake Michigan, especially around and south of Milwaukee. Dry conditions are expected tonight, with lows in the lower to middle 60s. Medium A warm airmass will be in place ahead of a slow moving trough axis that will be in northern or central WI. A westerly low level flow will sustain 925 temps near 20c or a smidge warmer.
635 AM EDT Mon Jul 31 2017 High pressure over the western Ohio Valley will build south and east into the Mid Atlantic through mid week. A stationary front stretching from Florida northeastward to just off the Southeast coast, will linger through the week, with areas of low pressure traveling up along the front. A strong cold front will move into the area late in the work week. Fair weather with below seasonable temperatures are expected today and tonight with high pressure continuing to exert its influence. A dry and subsident atmosphere will result in 0% PoPs through tonight with the just a couple of showers possible across the highest elevations of northwestern NC, western VA and WV and off the Carolina coast.

A stationary front stretching from Florida northeastward to just off the Southeast coast, will linger through the week, with areas of low pressure traveling up along the front. A strong cold front will move into the area late in the work week.
Backdoor cold front to bring drastic wind shift Tuesday. Hot and dry conditions will continue across the region today and Tuesday as high pressure remains over western Montana and central Idaho. Starting Tuesday night, a backdoor cold front will begin to push over the Continental Divide and will bring gusty northeasterly winds across western Montana.
Under clear skies, temperatures will quickly warm into the low to mid 80s today.
335 AM EDT Mon Jul 31 2017 Water vapor analysis at 07z reveals the persistent ridge in place over the Western US into the Southern Plains. Sfc analysis reveals a broad area of high pressure from the Plains to East Coast and a cold front draped across central FL west through the Gulf and into southern TX.
Still not all half bad as dew points remain in the low 60s.
Western Nebraska will be in persistent northwest flow aloft as a large upper ridge remains parked over the West Coast and a trough digs over the Midwest. The long range solutions also suggest a closed low developing over the Upper Miss Valley late week. The main story at the surface is a strong cold front dropping across the Plains midweek, followed by high pressure settling in from the Dakotas.
402 AM EDT Mon Jul 31 2017 High pressure and dry air will remain in control of the region through the middle of the week.
353 AM EDT Mon Jul 31 2017 High pressure will continue to provide dry weather and plenty of sunshine to the region today. High temperatures both today and Tuesday will reach into the lower to mid 80s.
156 AM CDT Mon Jul 31 2017 Another tranquil day expected across the Tennessee Valley as an upper ridge remains in control of the local weather. Should see slightly more clouds today as cirrus clouds are going to be streaming southeast along the upper ridge. The upper ridge starts to break down tonight with any afternoon cumulus dissipating with sunset. High level clouds should remain which will keep lows a bit warmer than previous nights, in the mid to upper 60s. This won't have too much of an impact on highs, maybe a deg cooler than what is forecast for today (Monday).
With the center of the high drifting slowly southeast of here, light southerly winds will develop. Highs very near normal are expected today with most locations in the low to mid 80s. An abrupt pattern change is expected by midweek as the mean flow becomes more northwest, and the eastern half of the nation becomes locked in to a long wave trough.
315 AM CDT Mon Jul 31 2017 The forecast area will remain under northwest flow aloft and the influence of high pressure at the surface centered north of the region. Flow in the upper levels will remain from the NW on Tuesday over the ArkLaMiss as a steep, anomalous ridge builds over the western CONUS and troughing occurs in the east.
The reason for increased rain chances this week is the upper high that has given us the hot and dry weather the past few days is finally retreating to the west leaving the South Plains under northwesterly/northerly upper level flow. This will send a series of upper disturbances and even a couple of cold fronts into the Permian Basin.
437 AM CDT Mon Jul 31 2017 Similar to this time yesterday, the High Plains are active with weakening storms across southwest KS.
334 AM EDT Mon Jul 31 2017 High pressure with cooler and drier air prevails through mid week.
428 AM EDT Mon Jul 31 2017 A large high pressure system in the Ohio Valley will keep our weather primarily dry through Tuesday. High pressure will provide another mostly sunny and warm day across the local area with high temperatures ranging in the lower to middle 80s. Conditions will be dry overnight with more valley fog as dew points remain in the lower 60s under mainly clear skies. High pressure will remain in the area but weak disturbances in zonal upper level flow may trigger more isolated to scattered thunderstorms during peak heating.
213 AM EDT Mon Jul 31 2017 High pressure over the Great Lakes will maintain mostly dry and mild conditions over the area into mid-week.
A non-tropical low pressure area is located west of Tampa FL. Don't think this will be too much of a limiting factor and will forecast lows on the cool side of guidance, mainly in the low to mid 60s. Would not be shocked at all to hear of some upper 50s in the typically cooler/sheltered locations.
339 AM EDT Mon Jul 31 2017 A weak cold front will drop south through the region today and will stall offshore overnight. Weak high pressure will build over the area on Tuesday and will shift offshore Tuesday night.
653 AM EDT Mon Jul 31 2017 High pressure will remain across the Great Lakes and Ohio Valley through Tuesday.
140 AM EDT Mon Jul 31 2017 High pressure extending from the Midwest, into the northeastern states, will keep our weather mainly dry through Monday. Skies will stay mostly clear through early Monday, with high pressure in control, and a fairly dry air mass in place. Warm air spreading out from under a large dome of high pressure over the Central and Western U. A cold front moving across Ontario Province will barely skirt our forecast area, possibly setting off an isolated thunderstorm on Tuesday.

606 AM EDT Mon Jul 31 2017 High pressure will continue to provide dry weather and plenty of sunshine to the region today. High temperatures both today and Tuesday will reach into the lower to mid 80s.
151 AM EDT Mon Jul 31 2017 High pressure with cooler and drier air prevails through mid week. High pressure centered over the region will be in control through much of the work week.
North of this low pressure area, an unseasonably dry airmass is in place, with precipitable water values expected to drop to around 1 inch or less today. While temperatures will still be warm today (upper 80s to around 90), the lower dewpoints (60s) will at least keep the heat a bit more bearable.
235 AM EDT Mon Jul 31 2017 Fair weather with below normal temperatures and humidity will prevail the next few days as Canadian high pressure works into the region.
Expect less coverage of showers and thunderstorms on Monday with models all showing an upper level ridge building into northern Wyoming. Models show the upper level ridge breaking down on Tuesday as a weak upper level disturbance moves southward across eastern Wyoming. Temperatures will be slightly cooler than average for this time of year with highs in the upper 70's (west) to middle 80's (east) across the area. Relatively mid weather will be over the CWA this period under a northwesterly flow aloft in a bit of an unusual pattern featuring a cool upper low over the Great lakes region.
The cold front will slowly push south and east across the area on Tuesday, with a good chance for afternoon and evening thunderstorms.
359 AM EDT Mon Jul 31 2017 High pressure will remain across the Great Lakes and Ohio Valley through Tuesday.
Another mostly clear and calm night across central PA thanks to sprawling high pressure building eastward across the Ohio Valley and fairly dry northerly flow. An upper trough crossing Quebec will push a weak cold front southward into upstate NY. Latest model runs continue to show isolated convection developing in vicinity of the Lower Lakes which may drift south/east into the northern tier of central PA during the afternoon/early evening as a few, brief, light-mdt rain showers before dissipating. A ridge of high pressure becoming located over the commonwealth Monday night/early Tuesday will lead to mainly clear and tranquil conditions once again with low temps near those of early Monday, or perhaps 2-4 deg F higher in some locations.
High pressure moving across central Indiana will keep dry weather in the forecast through Tuesday.
246 AM EDT Mon Jul 31 2017 High pressure will maintain dry and seasonable weather through early this week.
The unseasonal cold front associated with the upper trough remains stationary over north and central FL with a decent plume of moisture ahead of it stretching across the peninsula. In addition to this feature, the National Hurricane Center is monitoring an area of low pressure over the north central portion of the Gulf which could have the potential for tropical development today. The low to mid level flow is from west to east which will allow for thunderstorms development in the west coast to travel eastward today.
The SE-NW oriented upper ridge currently over the region is predicted (GFS/ECMWF/NAM deterministic) to retreat toward the NW somewhat during the period. The deterministic runs predict, and the GFS ensemble mean depict, the development of a weak trough/low over the MSA, and thus introduced isolated convection over the MSA for 06-12z Tuesday.
641 AM EDT Mon Jul 31 2017 A large high pressure system in the Ohio Valley will keep our weather primarily dry through Tuesday. High pressure will provide another mostly sunny and warm day across the local area with high temperatures ranging in the lower to middle 80s. Conditions will be dry overnight with more valley fog as dew points remain in the lower 60s under mainly clear skies. High pressure will remain in the area but weak disturbances in zonal upper level flow may trigger more isolated to scattered thunderstorms during peak heating.
321 AM EDT Mon Jul 31 2017 High pressure with cooler and drier air prevails through mid week. However, after the fog burns off we will see mostly sunny skies for much of the day with high pressure overhead.
426 AM CDT Mon Jul 31 2017 A cold front will move through the forecast area tonight and Tuesday.
Another trough is located from eastern MT into eastern WY. Upper level analysis shows high pressure over the southern high plains, with ridging extending northwestward into the Rockies. KUDX radar shows scattered showers and storms along the trough over south central SD, with scattered activity also over the central and southern Black Hills. Temps are mostly in the 80s, cooler where rain is or has recently fallen. Very warm temperatures can be expected Monday ahead of an approaching cold front, with highs in the 85 to 95 range. The cold front will slowly push south and east across the area on Tuesday, with a good chance for afternoon and evening thunderstorms.
