324 PM MDT Sun Oct 30 2016 Upper level analysis has broad ridge across the central CONUS, with large trof moving into the Pac Northwest. At the surface, high pressure resides across the Northern Plains with a warm frontal boundary across eastern Wyoming. However, the latest runs of the HRRR, NAM and GFS are showing the possibility for a few showers from northeast WY into northwest SD overnight as the warm front moves through. Low pressure will pass north of the area Monday morning, dragging a dry cold front quickly across the area during the morning hours. Highs will range from the 60s over northeast WY and the Black Hills to the lower 80s across far south central SD. On average a trough will persist in the eastern Pacific with a ridge across the central CONUS through the period.
fairly uniform cumulus field over northeast FL this afternoon with temps mostly in the lower 80s. This should set the stage again for quick decoupling of the low levels and a quick development of radiation inversion. Lows tonight about 1-2 degrees cooler with more clear skies and light to calm wind. Upper high builds over forecast area during this period. Models suggest weak coastal trough setting up Tues/Tues night. bringing cold front southward over forecast area Fri. Cooler drier air will follow the front this weekend. After cold front passes. Broad high pressure will slide southward through early in the week. The high builds southward causing winds/seas to decrease over our waters Thu/Thu night. Cold front moves over the waters Fri.
That said, not expecting the clouds to go anywhere as high pressure builds in tonight and all models hold ample saturation under a low level inversion. Going to need a cold front to sweep through late Monday night to finally scour out the persistent stratus. As for pcpn chances, time-height x-sections deepen the low level saturation into Monday night - especially the NAM - with Bufkit soundings showing a favorable drizzle setup. Pretty good isentropic lift through the low saturation, along with some omega. Decent frontogenetic response along the boundary with the low level jet funneling moisture into it and some upper level support from the right entrance region of a jet streak. Mostly the various models favor keeping the higher rain threat south of the local area, but chances will extend across northeast IA/southwest WI.
340 PM EDT Sun Oct 30 2016 High pressure will remain over the Southeastern U. today ahead of a dry, back door cold front that will move south through NC Monday. Surface cold front associated with this feature will push south across the Mid-Atlantic tonight, and will progress south through the area during the predawn hours late tonight/early Monday morning. Heights aloft rebound quickly, with the mid/upper level ridge to our west re-establishing itself over the area, resulting in notable warming aloft and the development of a strong subsidence layer(s).
327 PM CDT Sun Oct 30 2016 Shallow cold front pushed to the typical location of extreme NW AR to near KMLC before stalling. These clouds have recently begun to erode however they may begin to expand again after sunset only to be pushed northward as the frontal boundary lifts northward as a warm front tonight.
Otherwise, it's been a quiet end to the weekend, with upper level data showing ridging centered just off to our west, keeping things dry. At the surface, for most locations, winds have been light and on the variable side, thanks to a ridge axis sliding east-southeast through the region. Models remain in good agreement showing the upper level ridge axis sliding east through the Plains tonight, with southwesterly flow developing during the daytime hours tomorrow as an upper level system moves in from the West Coast. Speeds overnight look to stay in the 10-15 MPH range, thanks to a tighter pressure gradient ahead of an area of low pressure and trough axis moving through the High Plains. A trailing cold front will slide into the CWA, but not really moving through until Mon evening/overnight.
700 PM EDT Sun Oct 30 2016 A cold front will move through the area Monday and Monday night and be followed by high pressure returning for the middle of the week.
145 PM CDT Sun Oct 30 2016 The cdfnt to our north will stay north of the cwa as high pressure builds east overnight. The dry wx pattern will continue thru this period along with highs about 20 degrees above normal, thanks to strong upper ridging.
Our winds have already begun to shift back out of the south with temperatures ranging from the lower 60s to near 70.
345 PM EDT Sun Oct 30 2016 An upper level trough will cross the region tonight.
/issued 355 AM CDT Sun Oct 30 2016/ (Today and Tonight) It will be warm and dry again today with upper level high pressure aloft. Lee trough will not be as strong today, however, with south winds of 5 to 10 mph.
250 PM CDT Sun Oct 30 2016 A warm front will push into southwest North Dakota tonight. The bulk of the moisture and the best chance for rain appears to remain across northern North Dakota through most of the day along the northern edge of the trough.
324 PM EDT Sun Oct 30 2016 High pressure centered over the southeast plains will gradually filter in drier air into South Florida suppressing all the deeper moisture further south into Keys late this afternoon and early evening lowering the showers activity tonight across South FL. Abundant cloud-cover will keep temperatures mainly in the low 80s, with some mid-80s over the western interior.
High pressure will continue to keep this afternoon and evening pleasant with VFR conditions at all sites.
555 PM EDT Sun Oct 30 2016 An upper level trough will cross the region tonight.
232 PM EDT Sun Oct 30 2016 Cool and dry tonight Monday as high pressure moves in behind a cold front. Cold front bisecting the area is spreading showers with isolated thunder through the area. A pocket of clear skies has existed over our southeastern counties through midday, which has led to steepening of the low- level lapse rates. Temperatures will continue to fall in the wake of the cold front, dropping to near- normal values. Broad high pressure will return dry conditions to the area for Monday. Flat ridging aloft will persist through this period, providing mostly dry weather.
The responsible upper-level low pressure system is now directing plentiful Pacific moisture up and through the central and northern Rockies.
An upper level trough and associated cold front will move through the area Monday/Monday night.
1222 PM CDT Sun Oct 30 2016 A cold frontal boundary extending from central IL down into eastern KS will continue to push to the SE throughout the day placing the area in much cooler temperatures just slightly above normal in the mid 60s. A low level jet develops over Kansas ahead of the front and eventually push into our CWA with strong warm air advection allowing temperatures to rise back up into the low 80s and create breezy conditions by Monday afternoon.
High pressure centered north of the area weakens tonight before being gradually reinforced by another stronger ridge building down the eastern U. Temperatures will fall into the 60s over much of the region overnight, with highs again reaching the low 80s along the coast to mid 80s over the interior.
139 PM EDT Sun Oct 30 2016 High pressure will prevail through the weekend. A dry backdoor cold front will then move through the area on Monday, followed by high pressure returning for the middle of the upcoming week.
352 PM EDT Sun Oct 30 2016 Showers should end tonight as a cold front exits. High pressure should bring dry weather and a gradual warming trend through mid week. Cold front bisecting the area is spreading showers with isolated thunder through the area. A pocket of clear skies has existed over our southeastern counties through midday, which has led to steepening of the low- level lapse rates. Temperatures will continue to fall in the wake of the cold front, dropping to near- normal values. Broad high pressure will return dry conditions to the area for Monday. Flat ridging aloft will persist through this period, providing mostly dry weather.
Although think much of the low clouds will dissipate, could see some linger across north/northwest Oklahoma.
131 PM MDT Sun Oct 30 2016 Upper ridge will remain over the central plains today and tonight followed by gradual height falls on Monday as the next system enters the Pacific northwest. At the surface, lee trough will strengthen in eastern Colorado resulting in increasing south to southwesterly winds tonight and Monday, especially in western portions of the area. Another cold front will move through late Monday afternoon with winds shifting to northerly. Temperatures will warm into the lower to middle 80s ahead of the front Monday afternoon. Monday night will begin with southwest flow into the region due to a trough over the western CONUS.
An elongated area of high pressure extends from the deep South to the Atlantic waters off the southeast coast. This high pressure will weaken only slightly over the next 18 to 24 hours before being reinforced from the north. The local gradient will sustain breezy conditions though thanks to elongated and persistent low pressure stretch across the northern Caribbean. As a front/trough sags toward the southeast while weakening and becoming bridged at the surface, mid to upper level ridging amplifies across the eastern Gulf and Florida peninsula late Monday through the middle of the week.
1227 PM CDT SUN OCT 30 2016 Cold front is currently moving into northern Arkansas at this time, and should hang up and back north during the next 24 hours. Today Through Monday Night An upper ridge centered over west Texas will move east today and tonight will be over east Texas. Northwest flow over Arkansas will become zonal by Monday and southwest Monday night as the high center slides east to Florida. A cold front in western Oklahoma will move east today and enter Arkansas this afternoon. Highs today will be in the lower to mid 80s and lows tonight will be in the mid 50s to lower 60s. More of the same is expected for Monday with temperatures a few degrees warmer.
343 PM EDT Sun Oct 30 2016 Rain showers will end by early evening as low pressure moves off the New Jersey coast.
324 PM EDT Sun Oct 30 2016 A cold front crosses tonight. It returns as a warm front Monday night.
252 PM CDT Sun Oct 30 2016 Today has seen extensive stratus under the large high pressure over the Midwest, but within that, there have been notably large breaks in the cloud deck, with one of these from central Iowa through northeast Iowa. Tonight, the high pressure will slowly move east into the Great Lakes region, allowing winds to turn to the east and then southeast. For this reason, it seems prudent to go a bit warmer than model forecast for overnight lows tonight, counting on at least some periods of cloud cover, and go a bit lower on guidance highs Monday as we may see clouds especially early in the day.
1211 PM PDT Sun Oct 30 2016 A weak cold front will move through the area today. It will bring some showers and cooler temperatures to the area.
550 PM EDT Sun Oct 30 2016 Showers mainly south of Pittsburgh should end tonight as a cold front exits. High pressure should bring dry weather and a gradual warming trend through mid week. A cold front south of the PA/WV/MD border is progged to complete it's passage early this evening, ending the shower/isolated thunderstorm chances. Clouds should continue to persist much of the night in cool NW flow before subsidence with building high pressure results in a rapid clearing trend by early Monday morning. Flat ridging aloft will persist through this period, providing mostly dry weather.
253 PM CDT Sun Oct 30 2016 Broad upper level ridge will be the main story for the upcoming week. Ridging builds in over the region Monday morning and will persist through much of the week.
The cold front that entered the southern Missouri Ozarks today will stall out near the Missouri and Arkansas border tonight. The low level moisture behind the front will keep lingering low clouds across much of the area tonight. The nearly zonal upper air pattern will become more amplified heading into mid week as an upper level trough comes across the western states.
347 PM EDT Sun Oct 30 2016 High pressure across the western Great Lakes will shift east tonight and be overhead for Monday.
624 PM EDT Sun Oct 30 2016 High pressure across the western Great Lakes will shift east tonight and be overhead for Monday.
Upper air analysis this morning showed a ridge extending from northwestern Mexico to the northern plains with northwesterly to northerly flow over Texas. The upper ridge will move across the region keeping the weather dry during this period.
This has caused temperatures to be cooler, especially where the cloud cover has remained most of the day with highs in the low 60s. The cloud cover will prevent lows from dropping too much, with low temperatures tonight generally in the low 50s. Tomorrow, low pressure begins to build over the Rockies causing the pressure gradient over eastern Kansas to increase. Highs have been trending cooler than previous runs, but still unseasonably warm weather is forecast for tomorrow.
/This evening through Monday/ There was considerable drying in the low levels today as seen on forecast soundings with low status giving way to partial sunshine in many areas. Surface ridging is also currently across central Iowa and will slide east tonight with warm advection increasing later. Anticipate a re- expansion of the low clouds overnight across much of central Iowa as the moistening continues. This cooling will subside as the ridge moves east and some increase in readings is likely late tonight as the warm advection intensifies. /Monday night through Sunday/ On Monday moderate southerly breezes will promote warmer temperatures, however satellite trends and forecast soundings indicate that that stratus affecting much of the region today will persist, especially across northern Iowa.
238 PM EDT Sun Oct 30 2016 A cold front crosses late today and tonight. It returns as a warm front Monday night.
242 PM CDT Sun Oct 30 2016 Early-afternoon water vapor imagery depicted an amplifying mid- level ridge building through the Interior West into the High Plains, downstream from a vigorous upper low approaching the Pacific Northwest Coast. In the low levels, a ridge axis stretched from the upper Mississippi into mid Missouri Valleys as of 18z, while a lee trough was intensifying over the northern High Plains. Widespread stratus which formed last night within the low-level ridge axis is in the process of eroding this afternoon; a trend which will continue in evening. The low-level warm advection pattern will persist through Monday across the forecast area ahead a weak cold front which will approach from the west.
152 PM EDT Sun Oct 30 2016 High pressure will build in behind this morning's cold front and will settle over the Great Lakes for Monday.
The H5 ridge residing in the eastern Gulf migrates back west during the second half of the work week.
It's further eastward progression, and low pressure organizing across MT/WY will increase the pressure gradient overhead. Warmer and stronger southerly winds will be the rule overnight, as 850mb temps go from a CWA average of 6C this afternoon to around 18C by daybreak Monday. The low will shift to northeastern ND around 18Z Monday, pushing a cold front across the center of our CWA. This will also be near the time of peak heating, when temperatures rise into the upper 70s to low 80s over the southwestern quarter of the CWA, and drier air works in allowing dewpoints to fall into the low 30s and even upper 20s.
257 PM CDT Sun Oct 30 2016 "Indian Summer" conditions to to continue right into the first part of the work week as upper level ridge remains firmly in place over the southeast United States. A weak cold front nudging southeast toward the Ohio River this afternoon will stall just south of the region by around midnight.
251 PM CDT Sun Oct 30 2016 Skies are mostly sunny across much of the forecast area this afternoon with temperatures in the low to mid 80s. High pressure covers much of the southern U.

232 PM PDT Sun Oct 30 2016 As a weak cold front moves through today, some showers will continue to affect the area.
1241 PM MDT Sun Oct 30 2016 Upper ridge will remain over the central plains today and tonight followed by gradual height falls on Monday as the next system enters the Pacific northwest. At the surface, lee trough will strengthen in eastern Colorado resulting in increasing south to southwesterly winds tonight and Monday, especially in western portions of the area. Another cold front will move through late Monday afternoon with winds shifting to northerly. Temperatures will warm into the lower to middle 80s ahead of the front Monday afternoon.
The tail end of the lifting system to the north will move along the southern Wyoming border and force a surface cold front up against the eastern Uintas and into NW Colorado. The cooler air behind the front will bring a noticeable downturn in high temperatures north of the plateaus tomorrow. Mainly clear and cooler low temperatures will move in for Monday night.
145 PM EDT Sun Oct 30 2016 A cold front will push south through the area today and tonight, bringing a chance of showers. As high pressure travels east through the Great Lakes Monday into Monday night, the old frontal boundary will move back northeast as a warm front. Given sufficient heating along and ahead of the cold front, there could be a rumble of thunder over the southern two thirds of the forecast area this afternoon into early evening. The cold front will push south of the Ohio region tonight. It will be much colder by Monday morning with lows ranging from the lower 40s north to near 50 far south.
123 PM PDT Sun Oct 30 2016 A low pressure system will move through Central CA today.
A second surge of moisture associated with the low level jet arriving in the vicinity of 06z tonight. With the increasing stratus, may see some stratus on the ground especially in the higher elevations in southwest Minnesota. With the light winds, clear or clearing skies, and dry air, used GEM regional temperatures for lows in east central SD and extending down the James River valley, which were a fair amount cooler then consensus lows.
Moisture influx should begin tonight as high pressure shifts eastward allowing for deeper tropical moisture to stream into the region. Temperatures on Monday similar to today, except maybe a degree or two cooler in southeast portions where best moisture and precip chances will be. Min temps several degrees cooler over much of the area Monday night due to increased moisture.
/issued 1005 AM CDT Sun Oct 30 2016/ Skies are mostly sunny across the forecast area this morning with temperatures in the low to mid 70s. Another unseasonably warm afternoon is in store with highs expected to be in the low to mid 80s. /issued 309 AM CDT Sun Oct 30 2016/ An upper level ridge of high pressure will shift over the Mid South through the first part of this week.
The low level thermal trough has kept a good deal of cloud cover around and this is proggd to either dissipate this evening or lift northward into Monday as the southerly return flow sets up.
A cold front moved across northern Utah this morning and into central Utah this afternoon with drier and somewhat cooler air spreading in behind the front.
256 PM CDT WED AUG 3 2016 Large upper level ridge across much of the southern CONUS will continue to be our main weather influence over the next seven day forecast period. 92 Generally scattered showers and thunderstorms are expected through the week with highs in the lower to middle 90s.
342 PM CDT WED AUG 3 2016 The high pressure ridge over the area will slowly drift northward for the next several days.
344 PM CDT WED AUG 3 2016 Watching progression of cold front this afternoon as it moves east across the western Dakotas. Plenty of moisture and instability ahead of the front and also noting the approach of a potent upper level trough. On Thursday, much drier air will be moving in behind the departing cold front. Dewpoints will drop back into the 50s with high temperatures cooling down into the low to mid 80s.
An upper level ridge builds in on Thursday with locally driven winds expected. A very dynamic upper level low, currently centered over northwest Montana this morning, will eventually end up over southern Alberta by this evening.
308 PM EDT WED AUG 3 2016 A warm front will lift north across the area tonight into Thursday morning.
Today has been quite the change in temperatures across much of the Northern Rockies, with temperatures running about 10 to 20 degrees cooler than what we've experienced lately. a true depiction of how cool this low pressure system is. This cool spell will be short-lived, as high pressure and drier conditions set up once more across the region.
214 PM MDT WED AUG 3 2016 Upper low is over northern MT, and a 90-kt jet is rounding the base of the trough. At the surface, low pressure has moved into western ND. Cold front has begun passing through the CWA, with breezy southerly winds ahead of the front becoming gusty from the northwest behind. As the cold front pushes into moister air, storms will intensify. Eventually storms are expected to form into a line along the cold front, with large hail and strong winds will be possible. Temperatures will be much cooler, with highs in the mid 70s to mid 80s.
/Issued 1045 AM EDT WED AUG 3 2016/ The low cloud deck that has covered a large portion of the area this morning has been gradually scattering and dissipating through the late morning, and this trend will continue. upper ridge through the near term period. Models build a wedge-like ridge into the state from the northeast tonight through Thursday behind the surface wave lifting northeast. upper ridge tries to build back in from the west with 591dm sneaking into NW GA.
/issued 1102 AM CDT WED AUG 3 2016/ Another hot day is in store for the region, as the upper ridge remains anchored over TX.
With convective parameters indicating greater instability area-wide tomorrow in addition to the trough, will have likely pops for most locations in the afternoon.
Upper level high pressure remains the prominent weather feature over southern and central California this afternoon, resulting in dry weather and above normal temperatures. The high resolution models continue to indicate isolated showers over the Sierra Nevada around the Fresno/Tulare county line this afternoon. Otherwise, the much highlighted cooling trend begins tomorrow as an upper low moves south toward the northern California coastline. The one exception will be the southern San Joaquin Valley, where the cooler airmass will likely not reach that far south.
DECREASE IN SHOWERS AND THUNDERSTORMS LATE THIS WEEK INTO A trough of low pressure over the central portion of South Florida this afternoon will continue to move to the west northwest into the Gulf of Mexico tonight.
202 PM CDT WED AUG 3 2016 The focus is on tracking the upper level high and associated heat dome across the central part of the country. For Thursday the center of the upper level high will be west of the region over the central plains.
Southeast surface winds increasing and this should help mix the low level moisture somewhat, however highs in the lower 90 and high dewpoints look to increase HIs to around 100 or a few 100 to 104 spots in parts of southeast Nebraska. A convection-free night across the area will lead to a warmer day today.
352 PM EDT WED AUG 3 2016 An upper level ridge will continue to expand over the region through Thursday providing warm and mainly dry conditions.
A weak upper low is crossing central Arizona into the Four Corners area which will keep storms going overnight for western areas.
