A strong cold front will move in from the west today and be followed by a second cold front on Thursday. Cooler and drier air is expected for the end of the week under high pressure. Upper trough slowly plodding through the Great Lakes region will keep scattered showers and thunderstorms across central Pennsylvania into this evening as we will remain on the east side of the trough. A few will be strong to severe over the lower Susq, with potential for training echoes enhancing flooding threat in local areas. *Scattered strong to severe thunderstorms capable of damaging winds, isolated hail and locally heavy rainfall are possible Thursday afternoon and evening Low level convergence along a southeastward-moving cold front should trigger storms into the afternoon and evening.
1051 AM MDT Wed Aug 7 2019 Current surface analysis shows slow moving and weak cold front moving south across the area. Upper level analysis shows high pressure now centered over southern NM, with ridge extending north-northwest through the eastern Great Basin into the Pacific NW. Behind the front, highs will be a little cooler than yesterday, upper 70s to mid 80s most areas. As upper high shifts into west TX on Thursday, ridge is forecast to shift east and weaken some late in the week.
Cooler temperatures brought on by storms last night were only temporary, and we are well on our way to the upper 80s and low 90s.
A sfc cold front will precede the trough into the region, with current timing sliding it across the local area between roughly 20-04z. Weak high pressure still slated to build in post the Wed system with drier and cooler air accompanying it.
348 PM CDT Wed Aug 7 2019 Northwest flow aloft to continue over the Midsouth through the weekend, between an upper level ridge centered over the southern plains and a low amplitude trof over the eastern third of the U.
A strong cold front will move in from the west today and be followed by a second cold front on Thursday. Cooler and drier air is expected for the end of the week under high pressure. Upper trough slowly plodding through the Great Lakes region will keep scattered showers and thunderstorms across central Pennsylvania into this evening as we will remain on the east side of the trough. A few will be strong to severe over the lower Susq, with potential for training echoes enhancing flooding threat in local areas. The unsettled pattern will continue into Thursday as another cold front comes through, accompanied by another round of showers and thunderstorms later in the day. As front moves away and northwest flow takes over under the trough, cooler and drier air will move in.
100 PM CDT Wed Aug 7 2019 Thunderstorms exiting this morning, a chance for redevelopment later today and tonight, and somewhat cooler temperatures to end the week, are the primary highlights of the forecast.
Under northwesterly flow aloft, weak high pressure at the surface will help to keep a drier, more stable forecast in place through at least tonight, though there is a low-confidence possibility of convective activity currently in NE to migrate southeastward and clip parts of southeastern MO late in the day, as indicated by the CAMs. The models showed a tendency for another surge of drier high pressure air to sink into the region on Fri. After rather warm overnight temps on Thu night, highs Fri will be a few degrees cooler than the seasonable temps Thu, followed by lows in the 60s Fri night. We should start out with high pressure in control at the surface and weak northwest flow aloft due to a strong upper high centered over Texas.
246 PM CDT Wed Aug 7 2019 As cooler, drier and more stable air in the low levels settles south the mid levels will be a little slower to respond. High pressure will be in control of the weather Thursday and it should lead towards a very pleasant day.
The focus is an h850mb warm front poised along or south of the KS border.
339 PM EDT Wed Aug 7 2019 Cold front will finish crossing the U. High pressure will continue to build into the Upper Lakes through Thursday. winds will be pretty gusty especially over the warmer nearshore water areas.
Models show the ridge strengthening into the weekend but eventually elongating and settling to a slightly lower latitude mid-week.
High pressure ridging is in place over West Texas with little change to the forecast over the next several days as this dominates.
High temps still look to be in the low to mid 80s.
A lull in the activity occurs late tonight/Thursday morning before increasing thunderstorm activity spreads NE into the region Thursday afternoon/night ahead of a low pressure system approaching the Oregon coast.
342 PM CDT Wed Aug 7 2019 Active weather pattern will continue through the next 24 hours as forecast area remains positioned within the confluence of a mid- level high to the west and upper trough over the east. With the cloud cover and rainfall, temperatures will remain below normal on Thursday, topping out in the lower 80s.
For later this evening, a stray shower or thunderstorm is possible in the mountains and the foothills but expect much of the area to remain cooler and drier than yesterday. For Thursday, the ridge axis start to trend eastward as a low deepens over the Pacific Northeast.
240 PM CDT Wed Aug 7 2019 A cold front draped across central North Dakota will continue to be a focus for scattered shower activity through the late afternoon/early evening. Activity will diminish from west to east as high pressure will build over the northern Plains tonight, allowing for clearing skies, light winds, and very cool overnight temperatures for early August.
The only exception may be a few areas in the higher terrain as storms will tend to move east/southeast. Models in general agreement that much of the period will be dominated by a ridge axis to our west and northwest flow aloft over our area.
304 PM EDT Wed Aug 7 2019 A cold front will approach from the west this evening with scattered showers and thunderstorms ahead of it.
Tonight and Thursday The latest RAP analysis and satellite/radar imagery show a cold front moving to the southeast over far northwest Wisconsin early this afternoon. The cold front will be moving southeast across northeast WI in the evening, exiting over northern Lake Michigan and southern WI around 10 pm. Clouds will decrease thereafter, as northwest winds gradually push in cooler and drier air. Lows ranging from near 50 in the northwoods to the low 60s over east- central WI. The region will be on the southern periphery of troughing centered over northern Ontario. Should have enough moisture in the low levels after the recent rains for some flat fair weather cu popping with the heat of the day. Cooler highs ranging through the 70s.
The best combination of lift, instability, and shear will exist across northern Wisconsin as an upper low tracks through the Upper Great Lakes. Expect pulse type storms to continue to develop this afternoon and evening, then as a cold front begins to drop south storms should begin to merge into linear segments along the front.
Precipitation chances will return late tonight as another MCS propagates into western Missouri and eastern Kansas from the High Plains. At the same time a weak cold front will move southeast through Missouri and intersect the MCS in western Missouri.
Conditions were muggy across the rest of the forecast area as high temperatures climbed into the low to mid 80s and dewpoints approached the upper 60s and lower 70s. Spotty showers and storms will linger through Thursday morning, before diminishing early Thursday afternoon as high pressure builds in at the surface.
140 PM EDT Wed Aug 7 2019 [Through 18Z Thursday] Storms will be scattered about the region again this afternoon, with the highest probability of impacting a terminal at TLH.
High temperatures will only reach the lower 70s in many areas, with slightly higher temperatures where clouds clear during the mid afternoon. For Thursday, look for quiet weather with highs generally in the lower to middle 70s.
Lows overnight will be able to drop into the low to mid 60s. Then a cold front brings another chance for afternoon showers and storms that could become severe south of US-24.

259 PM CDT Wed Aug 7 2019 At 3 PM, a scattered thunderstorms were developing along a cold front which extended from Dodge Center MN to Wausau WI.
There could be a gradient of temperature from the lower 80s up north along I-70 to the mid/upper 90s around the Red Hills, but it all depends on where the resultant outflow boundary sets up afternoon.
Temperatures are on track this afternoon and will max out in the lower to middle 90s. Overnight lows will be in the lower 70s. The upper level trough and associated surface boundary will continue to shift east of the region with a dry northwest flow in place aloft. Most guidance indicates a dry day across the area, however there are some indications in the high-resolution mesoscale models that isolated convection could develop south of the Augusta area during the afternoon and early evening in closer proximity to the deeper moisture. Temperatures will warm to highs in the mid to upper 90s with nighttime lows in the lower 70s.
This wave will help drive a cold front through the CWA tonight. Temperatures at 1 pm, were in the low to mid 80s. Cold front will track southeast through the CWA between 00-09z this evening. slightly cooler and more comfortable conditions will be the norm, as cold front continues to push south into MO and southern IL and high pressure builds in from the northwest. Highs will reach the low to mid 80s, with lower dewpoints making for another beautiful summer day.
Combined with instability, this moisture will generate isolated showers and thunderstorms for this afternoon and evening - especially over the higher terrain. Isolated thunderstorms early afternoon becoming scattered by evening hours for the higher elevations of SE Oregon and SW Idaho, especially along the Nevada border.
524 PM MDT Wed Aug 7 2019 Strong upper ridging is persisting across the southwest to central CONUS.
Latest surface analysis is showing that a stationary front has pushed well south of the CWA into Oklahoma and Arkansas and a cold front was located over the upper Midwest. Precipitation chances will return late tonight as another MCS propagates into western Missouri and eastern Kansas from the High Plains. At the same time a weak cold front will move southeast through Missouri and intersect the MCS in western Missouri.
Upper trough moving se across s Ga into the Fl panhandle will maintain scattered storms mainly north of I-10 corridor till at least midnight.
1028 PM EDT Wed Aug 7 2019 Currently - A narrow pressure ridge extends across the Keys. Day time heating over Florida and Cuba dissolved the ridge near the Keys, resulting in a col and associated variable winds across the area. Meanwhile, an upper level trough covers the eastern United States, keeping any hint of ridging well away from the Keys. A couple of rounds of island cloud lines were able to develop, primarily in and around the Lower Keys. A weak narrow ridge will extend across Keys waters overnight.
A cold front will bring in slightly drier air late tonight. Another cold front will move across the region on Thursday. Cooler and drier air is expected for the end of the week under high pressure. Upper trough slowly plodding through the Great Lakes region keeping scattered showers and thunderstorms across central Pennsylvania into this evening as we will remain on the east side of the trough. Severe threat has ended as the Lower Susq has been worked over. *Scattered strong to severe thunderstorms capable of damaging winds, isolated hail and locally heavy rainfall are possible Thursday afternoon and evening Low level convergence along a southeastward-moving cold front should trigger storms into the afternoon and evening.
847 PM CDT Wed Aug 7 2019 Scattered thunderstorms are possible on Thursday as a cold front pushes south into Illinois.
Look for a little breeze overnight longer with warmer temps likely.
Low pressure off the west coast will slowly move into the region Thursday through the weekend with cooler temperatures and increased wind over the mountains and desert areas. The flow is in between an offshore trough and an anticyclone over the SW U. Models prog for the trough to move through S CA keeping the S flow and moisture over central CA through tomorrow afternoon.
This would support falling temperatures into the mid 40s, and possibly into the lower 40s far north tonight. A cold front draped across central North Dakota will continue to be a focus for scattered shower activity through the late afternoon/early evening. Activity will diminish from west to east as high pressure will build over the northern Plains tonight, allowing for clearing skies, light winds, and very cool overnight temperatures for early August.
A cold front will bring in slightly drier air late tonight. Another cold front will move across the region on Thursday. Cooler and drier air is expected for the end of the week under high pressure. Slow moving upper trof tracking through central and eastern PA this evening, with scattered showers and thunderstorms still kicking as we head into late evening. *Scattered strong to severe thunderstorms capable of damaging winds, isolated hail and locally heavy rainfall are possible Thursday afternoon and evening Low level convergence along a southeastward-moving cold front should trigger storms into the afternoon and evening.
745 PM EDT Wed Aug 7 2019 Early evening water vapor satellite imagery is showing a band of deep moisture over the Florida Peninsula to the south of an upper level trough swinging through the eastern US. This trough helped enhance showers and thunderstorms moving east across the forecast area today under westerly flow, with a couple of bands of storms continuing to linger across southwest Florida. High pressure will continue to ridge across the southern Gulf of Mexico through the rest of the week and into the weekend, keeping westerly winds in place.

Lows overnight will be able to drop into the low to mid 60s. Then a cold front brings another chance for afternoon showers and storms that could become severe south of US-24. Behind the cold front, expect a drier airmass for Friday and the weekend. Subtle low level ridging and 925-850 mb theta-e minimum over IN and Lower MI will keep conditions dry/mostly clear into this evening. Still cannot rule out a stray, diurnally-driven, afternoon shower across northwest OH given convergence along any lake boundaries and close proximity to lingering trough axis over central OH. Attention later tonight into Thursday will turn to chances for showers/storms as a round of Great Lakes/Ontario height falls forces a cold front through. Somewhat breezy and a little cooler otherwise post-frontal tomorrow.
Will then see a low pressure system and associated frontal boundary approach, with showers and thunderstorms developing across the western part of the CWA Friday afternoon. High temperatures today will range from the mid 70s east to the lower 80s west, with lows tonight ranging from the mid 50s east to the mid 60s west. Highs on Friday will be in the lower to mid 80s.
Skies clear out tonight as high pressure builds in from the northwest. Tomorrow looks like another great summer day with plenty of sunshine, and highs in the mid to upper 70s along with drier dewpoints in the low 50s. High pressure will be centered over the area by Friday morning, with temperatures for the most part starting out in the 50s across the area.
Center of high pressure still nudging into the area from Sask keeping winds from going completely calm, but this is expected to change especially in North Dakota. High temperatures will only reach the lower 70s in many areas, with slightly higher temperatures where clouds clear during the mid afternoon. For Thursday, look for quiet weather with highs generally in the lower to middle 70s.
Given, the higher than normal moisture content, some localized flooding is possible as well. The threat for storms will continue through the weekend as a larger low pressure system off the coast of California moves northwards along the coast. An upper trough off the Pacific coast will keep a fairly moist southwesterly flow over the region.
1117 PM MDT Wed Aug 7 2019 Strong upper ridging is persisting across the southwest to central CONUS.
and Friday A pleasant day will be on tap for today in the wake of a cold front exiting the region with mostly sunny skies and dry weather expected.

1042 PM CDT Wed Aug 7 2019 At 3 PM, a scattered thunderstorms were developing along a cold front which extended from Dodge Center MN to Wausau WI. High pressure will then provide dry weather through Friday night.
Tonight Through Friday The upper ridge will remain centered over Texas through Friday. Also, a slow moving cold front in Missouri will slowly sag into north Arkansas Thursday.
Comfortable readings continue with lows from the mid 50s in the east, to mid 60s west where the southerly flow arriving earlier will keep temperatures a little warmer. While dewpoints will return to the lower to mid 60s by afternoon, high temperatures will remain near to slightly below normal in the upper 70s to mid 80s. Wave riding over the upper ridge could spark scattered storms in the evening and overnight hours.
Looking ahead into the weekend, a trough of low pressure will continue to develop off the Pacific west coast causing the high to shift east over New Mexico.
In the mid levels the northwest flow aloft has remained over the area for the previous several days, and that has allowed for embedded troughs to move through. Another such trough will move through the area this morning, perhaps causing a widening of the ongoing precipitation into portions of extreme eastern Kansas and western Missouri.
329 AM EDT Thu Aug 8 2019 A cold front will move across the area today. There is a small chance for thunderstorms to develop again along the cold front this afternoon but that will primarily be south of U.
1159 PM CDT Wed Aug 7 2019 Active weather pattern will continue through the next 24 hours as forecast area remains positioned within the confluence of a mid- level high to the west and upper trough over the east.
329 AM CDT Thu Aug 8 2019 (Today and Tonight) Another hot and dry day is expected across West Central Texas today as upper level ridging dominates the weather pattern.
Short wave trough moving through the region early this morning triggering a few widely scattered showers in the east Midlands. The upper trough and weak surface boundary will move slowly southeast across the area into the afternoon. Mostly clear overnight with temperatures in the low to mid 70s. A short wave trough will pass through late in the afternoon and into the evening hours creating a slight chance of thunderstorms.
