Generally quiet weather is expected for this weekend as high pressure is projected to build into the region.
Dry and above normal temperature are expected this afternoon with highs in the lower to mid 90s.
354 PM EDT Thu Sep 5 2019 Expect increasing clouds late tonight with lows in the lower and middle 50s.
Although the 500 mb ridging will persist over the region throughout tomorrow night, the atms will remain moist enough to require the mention of sct mainly afternoon and early evening conv. Will opt for a general blend of these models for both the highs and lows through the short term.
Showers and thunderstorms will develop this afternoon and become widespread after 06/00z as an upper level trough approaches from the southwest.
Friday will warm up a little more efficiently, with some compressional warming ahead of a reinforcing cold front.
As the upper-level trough and Hurricane Dorian move off to the northeast, the pressure gradient generating this wind will weaken, calming winds back down tonight. Wouldn't be surprised if somewhere dropped into the low 50s. Friday should be another nice day with sunny skies and lower humidity, but with less wind temperatures will probably rise a couple degrees warmer than today.
Temperatures have climbed into the low to mid 90s, although the cu field that has developed across portions of the area have kept readings a few degrees cooler.
VFR conditions will prevail thru the period with light winds beneath high pressure aloft. /Issued 923 AM CDT Thu Sep 5 2019/ Our area remains under the influence of a mid level ridge that is anchored from Colorado southeast to the Red River valley. /Issued 305 AM CDT Thu Sep 5 2019/ Yet another hot day in store as the upper ridge remains locked in across the central Rockies into the central/southern Plains.

High pressure will continue to build over the area, with clouds from Dorian slowly exiting overnight and Friday morning. A mostly dry cold front will sag south through the forecast area overnight Friday.
An approaching upper level trough deepened the marine layer overnight, to about 1500 feet deep. The upper trough will move across northern California tonight with a brief period of ridging along the coast during the day Friday. By the weekend, a deep upper trough is progged to move across California bringing sharply cooler temperatures to the area, and precip chances to higher elevation areas well to our north and east.
A weak cold front has stalled across southeastern Kansas and southwestern Missouri early this morning. The front will lift back to the northeast this morning and afternoon as a warm front.

High pressure in place across the Great Lakes will continue to provide pleasant weather to Indiana Tonight. A weak cold front is expected to push across the state Friday.
202 PM MDT Thu Sep 5 2019 Mean troughing will continue into central Canada, supporting a continued southward bias to the jet stream and associated storm track. Expect cooler weather with passing impulses emanating form the NE Pac upper trough. Upper trough will push east and support high centered pos theta-e adv over the west this evening shifting east into Friday morning.
309 PM CDT Thu Sep 5 2019 Quiet weather continues as high pressure continues to impact the region. Lows tonight will be in mid 60s to around 70 with highs on Friday from the mid 80s N (owing to the passage of a weak cold front) to the mid 90s S.
Models show the clouds hanging tough along the highway 2 corridor into the afternoon, when some breaks may start to occur. Depending on how long these clouds hang around, they will likely play havoc with the high temperature forecast. Shower and thunderstorm activity will clear the region by midday, giving way to partially clearing skies and warmer afternoon highs in the 70s.
Convective allowing models are keying in on the potential for a line of thunderstorms to pass through north- central Idaho and western Montana (mainly south of I-90) during Friday afternoon with the main trough progged to move through the region.
329 PM CDT Thu Sep 5 2019 After an unseasonably warm afternoon, a weak cold front will move southward through the region tonight, bringing just a smidge cooler temperatures for Friday, and gradually falling dewpoints through Friday night. The pattern changes this weekend as the mid-level ridge breaks down and a trough comes onshore from the Pacific.

Readings were in the low to mid 70s with light north to northeast winds. and coupled with a light north breeze it should feel cooler. Tonight's lows will drop into the low and mid 60s for most.
Drier air advecting into the area with light winds will allow slightly cooler temperatures tonight inland with readings in the upper 60s by morning.
1120 AM MDT Thu Sep 5 2019 Water vapor shows upper ridge rebuilding into the Northern Rockies with northern extent of monsoonal moisture lifting northward across WY. Dry cool front will continue working southeast through our zones this morning and will result in slightly cooler temps today. Weak upper wave embedded within the ridge could bring a storm or two to our southwest zones late tonight.
/issued 436 AM CDT Thu Sep 5 2019/ (Today and Tonight) Afternoon highs today will again be warmer than usual highs for early September. The upper ridge will continue to dominate.
VFR will prevail at all sites over the next 24 hours as high pressure dominates.
322 PM CDT Thu Sep 5 2019 The upper-level ridge will continue to dominate the weather across the southern Plains region into the weekend.
208 PM CDT Thu Sep 5 2019 As Dorian heads up the east coast, high pressure near the Great Lakes is helping to keep our area relatively cool and dry. As the High moves to the east tomorrow, our winds will turn to the south and higher dew points will move in. A weak cold front moves through Friday evening.
436 PM EDT Thu Sep 5 2019 The surface analysis shows high pressure to our northwest and Dorian to the southeast. These diurnally driven cumulus will dissipate with the setting sun this evening, and then we will see mostly clear skies, with high pressure and ridging remaining in control. This will lead to some fog tonight mainly in the valleys, but you could see it more elsewhere depending on how the night trends, with good subsidence from a nosing upper level ridge. This upper level ridge will break down some on Friday, as a weak cold front progress southeast into the Ohio Valley. Given the low level cloud cover provided by the front and did opt to leave any mention of fog out of the forecast for now.
1153 AM MDT Thu Sep 5 2019 Some very light isolated showers are continuing this morning across eastern Utah as moisture continues to increase and rotate around the area of high pressure situated to the east. 75 to 1 inch range but the dry air still remains at the low levels. A trough will move into the Pacific Northwest Friday and track across the northern Rockies, allowing for another increase in storm activity Friday afternoon and evening, focused over the north and areas along the western Colorado divide.
320 PM CDT Thu Sep 5 2019 High pressure will bring mostly clear skies, light winds, and comfortably cool conditions this evening.
1158 AM CDT Thu Sep 5 2019 Upper ridge remains anchored from the northern/central Rockies across the central/southern high Plains. Another weak cold front is progged to move south across Kansas during Friday with slightly cooler (not as hot) weather, more noticeable closer to the I-70 corridor in central Kansas.
1250 PM CDT Thu Sep 5 2019 /This Afternoon through Friday/ Afternoon satellite imagery shows a scattering of cumulus throughout the state capped at around 7000 ft beneath a large mid level ridge. Despite some cloud cover, the lower atmosphere is relatively dry through North Texas, and afternoon dewpoints have fallen into the upper 50s and lower 60s. Light winds should result in overnight lows in the lower 70s in most locations with urban areas in the mid/upper 70s. Friday will feature similar weather to today with highs near 100 degrees as the upper ridge strengthens some.
By Friday morning, a cold front will push southward through the forecast area, bringing in drier air and cooler temperatures.
317 PM EDT Thu Sep 5 2019 High pressure will move east of the region this evening to New England overnight as low pressure over the upper Mississippi Valley moves to Lake Michigan by morning. The low pressure area will move southeast across the area on Friday and weaken as it drags a weak cold front across the region toward evening. A ridge of high pressure will build east over the region over the weekend. Fair weather will continue tonight as high pressure drifts by to the east. On Friday cloudiness will increase as the weak low pressure area approaches the region. The low will be weakening and moisture is somewhat limited but the consensus of the CAM ensembles produces widely scattered convection over the region. High temperatures will be in the lower to mid 70s.
Broad upper troughing persisting over the eastern U. Highs will still be slightly above seasonal normals (mid/upper 80's), but the lower humidity will make it feel much more comfortable. The biggest story will be the heat due to a building ridge of high pressure. To start the period, Dorian will be well off to our east with a cold front dropping down out of the Ohio River Valley.
303 PM EDT Thu Sep 5 2019 High pressure over the area will bring quiet weather and pleasant temperatures through the end of the work week and into the weekend. High pressure is over the area this afternoon. Under the high with calm surface winds and no low clouds, valley fog will be widespread in nepa and south central NY. Low temperatures will be from the mid 40s to the low 50s. More showers for the entire area from an upper level wave and trough dropping southeast into the area. Low temperatures in the low and mid 50s.
Even though skies have mostly cleared from this morning's stratus episode, area temperatures are running much cooler than yesterday at this time. Current readings are ranging from the mid 60s to the mid 70s most locations, with some areas as many as 14 degrees cooler than 24 hours ago. Cooler temperatures today are due in part to an upper level trough currently moving across northern California. After the trough moves through, high pressure aloft will briefly build over California on Friday. This should bring slightly warmer high temps to the area for Friday. By the weekend, a deep upper trough is progged to move across California bringing much cooler temperatures to the area, and precip chances to higher elevation areas well to our north and east.
Moving forward, we enter a period characterized by the presence of a strong and sustained upper-level ridge over the central CONUS. Despite the record heat, dew point values should mix out into the high 60s across inland areas tomorrow afternoon, resulting in heat index values below advisory criteria.
200 PM EDT Thu Sep 5 2019 High pressure with dry conditions Friday.
1008 AM CDT Thu Sep 5 2019 The cold front moved through this morning, and dew points have dropped down into the mid 60s.

243 PM CDT Thu Sep 5 2019 243 PM CDT All and all a pleasant afternoon weatherwise as high pressure is right overhead, making for mostly sunny conditions and light winds. With the high in place, a lake breeze has formed and will continue inland, and this will keep conditions comfortably cool, upper 60s near the lake to the lower to mid 70s inland. The system's cold front will quickly drive in during the day tomorrow.
348 PM EDT Thu Sep 5 2019 High pressure over the area will bring quiet weather and pleasant temperatures through the end of the work week and into the weekend. High pressure is over the area this afternoon. Under the high with calm surface winds and no low clouds, valley fog will be widespread in nepa and south central NY. Low temperatures will be from the mid 40s to the low 50s. More showers for the entire area from an upper level wave and trough dropping southeast into the area. Low temperatures in the low and mid 50s.
Models still show the cloud cover along the highway 2 corridor slowly lifting by late afternoon or evening. Shower and thunderstorm activity will clear the region by midday, giving way to partially clearing skies and warmer afternoon highs in the 70s.
313 PM CDT Thu Sep 5 2019 An area of low pressure was located in NW Minnesota with a cold front extending to the southwest into the Central Plains. This Evening through Friday A cold front will move through late tonight into early Friday morning.
Broad High Pressure, centered on the OK/TX Panhandles at mid- levels (700 mb, 500 mb) will continue to keep the WFO PAH forecast area along the southern limb of northwest flow aloft, adjacent to the eastern limb of the southwestern U. ridge. This ridge is expected to move little during the short term period.
348 PM EDT Thu Sep 5 2019 A weak cold front will push south across the area this evening. High pressure will build down from the north late tonight and crest over the area early Friday.
1038 AM CDT Thu Sep 5 2019 A cold front moved through the area overnight and helped cool down our temperatures as well as lower the humidity. Satellite and analysis charts show high pressure building over the region so expect dry conditions with sunny skies today. /issued 252 AM CDT Thu Sep 5 2019/ Weak cold front struggling to proceed through the Midsouth this hour. Readings were in the low to mid 70s with light north to northeast winds. and coupled with a light north breeze it should feel cooler. Tonight's lows will drop into the low and mid 60s for most.
333 PM CDT Thu Sep 5 2019 The region is currently under high pressure with clear skies seen on satellite. Temperatures are a little cooler than what we've been dealing with as the area is sitting in the mid-to-upper 80s. We've also seen a noticeable drop in the humidity today with dew points in the low 60s to low 70s. Tomorrow will be much more Summer-like with highs in the low-to- mid 90s. Southerly winds will bring the humidity back into the region as well with dew points back into the low-to-mid 70s.
The ridge will begin to pull away tonight and a cold front will move southeast across Missouri and Illinois on Friday. Expect mainly sunny skies again on Friday ahead of the cold front, so with southwest winds and 850mb temperatures climbing to near 20C, we should be able to climb into the upper 80s and lower 90s along and south of I-70.
Surface analysis showing the area under a weak ridge providing a predominant light and somewhat variable flow. Will see an eastward advance of the aforementioned upper ridge going through the weekend, in concert with an easterly wave moving west across the western Gulf of Mexico. High pressure will maintain a dry weather pattern through the Friday and the weekend with winds remain light and somewhat variable.
234 PM CDT Thu Sep 5 2019 Temperatures have soared today with afternoon mixing behind the low. High pressure and lighter winds will bring somewhat cooler, but still above normal temps on Friday as upper ridging pushes further into the region.
Mostly sunny and mild on Friday with highs from the lower/mid 70s north and east.
/Tonight through Friday night/ Over the short term period, the aforementioned upper level ridge will remain centered over the western half of the Southern Plains and continue to extend into our region. Ridge-related subsidence will remain over the region, keeping our area with mostly sunny/partly cloudy skies and rain-free. The good news is that the dew points will continue to mix out during peak heating hours into the low to mid 60s.
