126 AM EDT Tue Oct 10 2017 Look for areas of fog to develop by daybreak as early morning temperatures fall into the lower to middle 50s. Mix out has been very slow today with overall weak dry air advection in the lower troposphere and waning Oct sun angle. Warm front will be approaching in the late afternoon but our CWA will reside in dry easterly flow with a pronounced theta-e sink for much of the day. Slightly cooler thermal profiles ahead of the warm front and increasing clouds will likely keep highs in the low 70s for most locations. Some rain virtually assured with the highest totals likely north of US-24 where better synoptic forcing/UVM resides.
301 AM CDT Tue Oct 10 2017 The upper level trough was ejecting out of the southern Rockies and onto the Southern High Plains overnight, and will move off towards the Great Lakes later this evening. As upper trough moves through Kansas and on up into Iowa, we could see a few scattered rain showers develop on the backside of the system through the morning hours. Temperatures will quickly rebound back into the 80s towards the latter half of the week as trough moving into the western CONUS places the area back in southwest flow aloft.
412 AM CDT Tue Oct 10 2017 A positively tilted upper trof was centered from western KS into the TX Panhandle early this morning. The models are in relatively good agreement with the upper trof taking on a negative tilt as it advances east-northeast into the Mid MS Valley today. There should be an uptick in coverage of showers and thunderstorms this afternoon not only along and ahead of the advancing front, but also extending northward into northeast MO in response to strong large scale ascent/forcing with the upper trof and frontal forcing. The main threat of storms this evening should be across IL along and ahead of the advancing cold front. The upper trof and attendant low however will be moving to the east at a good clip and I think most of the precipitation will be over by midnight.
322 AM CDT Tue Oct 10 2017 The well advertised, strong cold front has already crossed into Mexico early this morning. An upper trough over the TX Panhandle this morning will lift into the Mississippi River Valley today as high pressure settles in at the surface over Texas. Upper ridging over the SE U.
The low will track northeastward along the boundary today, bringing periodic showers and thunderstorms to central Illinois. There is still a considerable degree of model spread concerning the exact track of the low, but general consensus takes it to northeast Missouri/southwest Illinois by 00z. think showers and thunderstorms will become widespread today and tonight as the low passes through the region. Despite upper ridging in the wake of the system, clouds will be very slow to clear as boundary layer moisture becomes trapped beneath a strengthening subsidence inversion.
A broad upper ridge will build into Montana today, with a trough over British Columbia moving generally southward into the Pacific NW. With winds out of the south and southwest today, warmer air will move into the region, with high temperatures this afternoon expected to reach the 60s across NE Montana. The upper ridge begins to move eastward Wednesday, and expect slightly warmer temperatures with northeast Montana seeing high temperatures in the mid to upper 60s.
A cold frontal boundary was located from the TX Big Bend region east and northeast through the eastern Red River Valley. This frontal boundary will continue to slide southward as the parent waves continues it's north and easterly progression into the lower Missouri River Valley. Along and ahead of this front, showers and thunderstorms are expected to develop by mid to late morning, first across the northern Ranchlands, eventually dropping southward into the lower valley. We have gone the warmer route for the lower valley as we have been sitting in some cases in the lower 80s much of the night with mostly clear skies. Though, could be a few degrees cooler if clouds/precip develop sooner.
Northwesterly winds and high pressure building eastward from the Great Lakes will result in clearing skies during Tuesday, with high temperatures reaching the upper 60s to lower 70s. Will begin to see some better low-level drying during Tuesday morning, from west to east, with clouds lingering longest in vicinity of the higher terrain with nwly upslope flow into the nrn Adironacks and nrn Green mtns. Tuesday max temperatures reaching the low 70s in valley locations. Bulk of energy and moisture looks to stay south of the North Country due to the ridge.
Strong compact upper low centered near Elkhart at midnight will slide east to near Medicine Lodge by sunrise. At any rate, radar shows rain showers across the NE panhandles rotating NE toward Kansas ahead of the upper low. Cold air advection will ensure most locations end up in the mid to upper 30s near sunrise, with readings closer to freezing across the western/NW zones.
Current temperatures are mostly below freezing across the region. High pressure is currently centered over the high plains of WY/SD/NE with a ridge extending northeast through central ND. This ridge of high pressure will drift southeast and extend from Fergus Falls to Bemidji by midnight. The cumulus clouds across the region currently are expected to dissipate quickly late this afternoon and this evening with loss of daytime heating and the high moving southeastward across the Red River Valley. but with the clear skies and deep cool air, temps should still drop below freezing across the entire area. Winds will increase from the south-southwest, while low pressure gets organized in the lee of the Rockies.
427 AM CDT Tue Oct 10 2017 Current surface analysis places high pressure from the upper midwest through the northern/central plains into the central Rockies. Freezing temperatures are noted over many portions of the area, though a few spots over the north have remained a bit on the warmer side as a few clouds pass over, though have seen temps dive down as the clouds exit. Upper flow shifts southwest as trough digs into the western United States.
336 AM PDT Tue Oct 10 2017 Temperatures will trend several degrees cooler through the end of the week.
The main surface synoptic cold front attached to the low, currently over the eastern half of the Wichita Metro area, basically along the KS Turnpike. Low level moisture continues to increase just ahead and to the northeast of the low for areas east of the KS turnpike and south of Highway 54. Placement of the warm front and northward progression of the low level moisture will be critical to placement of severe potential for the late afternoon and early evening hours. Could also see a few elevated severe storms to the north of the cold front across portions of central KS given the increasing steep lapse rates and bulk shear into the evening hours. chilly temps) push south across the region with high temps on Tue only in the low 50s. As the ridge moves over.
633 AM EDT Tue Oct 10 2017 High pressure will continue to ridge into the area from the Atlantic through Wednesday.
Warmer and breezy conditions return on Tuesday. An upper level low pressure moves into the region Wednesday, providing cooler and unsettled conditions expected for the remainder of the work week. Gusty west winds of 25 to 45 mph were common across the N-central plains today due to a lee- side trough. The pressure gradient tightens as a longwave trough moves into the PacNW. Temperatures trend warmer on Tuesday amid the strong southwest flow. A Pacific front crosses the Rocky Mountains on Wednesday, producing areas of rain and mountain snow along the Continental Divide and the higher terrain of southwest Montana.
Moisture from the Gulf coast is getting squeezed northward between an approaching low pressure system across the plains states and a high pressure system across the southeast.
1235 AM CDT Tue Oct 10 2017 A strong cold front pushed through the region last evening. WV shows the upper trough over SW CO/NW NM at 18, but the cold front ended up a little faster than previously advertised, and fropa'd KMAF right at 17Z, w/little fanfare other than establishing the high temp for the day. The cold front will slow due to diurnal heating this afternoon somewhere invof the Pecos River, then pick up speed after sunset. Model temp progs suggest nrn Lea will stay well-abv freezing, w/post-frontal winds to keep things mixed.
A series of Pacific weather disturbances will impact mainly northern Utah with cooler temperatures during the latter half of the week.
This will result in a cooler day west of the Cascades, but areas to the east may see a slight increase in temperatures thanks to dry and warming downslope winds. Cool, damp, showery weather continues into Wednesday as an upper low settles in over us.
314 AM EDT Tue Oct 10 2017 Cold front weakens as it enters southeast OH on Wednesday.
Upper ridging over the region will keep the area dry today through most of Wednesday. A Pacific cold front will bring a chance for showers and a wind shift to the northwest Wednesday evening. High temperatures in the 60s can be expected today, with slightly warmer temperatures for Wednesday as downslope flow strengthens.
318 AM EDT Tue Oct 10 2017 A cold front will approach from the northwest today and cross the region early tonight.
311 AM CDT Tue Oct 10 2017 311 AM CDT GOES-16 water vapor imagery this morning shows a small, but potent, closed mid-upper level low moving east across the central/southern high plains. The central plains mid-upper level low is forecast to lift out negatively tilted across the mid-Mississippi Valley region tonight. High pressure will move across the upper lakes region today and tonight as weak low pressure moves into the southern lakes region tonight.
The area remains under the influence of high pressure today with the upper ridge sliding westward with the center shifting to the southeast while at the surface, the CWA remains on the western side of the Atlantic high.
A closed upper low will move from central Kansas early this morning into Iowa and northern Missouri late this afternoon. Better mixing across the north central, will keep lows mainly in the lower 30s, while the coolest reading in the upper 20s forecast to reside from central Nebraska westward up the North and South Platte River valleys. With much of western Nebraska now experiencing sub freezing temperatures early this morning, no new freeze headlines are planned for tonight.
With the anticipation of clear skies and light wind tonight, near or slightly cooler than guidance lows will be forecast. The cooler temperature trend will be monitored for need on the day shift.
Seasonably cool and mostly cloudy weather to end the week should be replaced by more sunshine and return of warmer temperatures for the weekend. A period of moderate to locally heavy rainfall appears possible through the first half of the day across western portions of the CWA where combo of well above normal PW, low level convergence and terrain enhanced south- southeast moisture transport along warm frontal zone may support pockets of 1" pcpn totals.
217 AM MDT Tue Oct 10 2017 A Positively tilted ridge will be building in from the west today along with temperatures inversions this morning.
With 850 mb temps near 0C, high temps will range from the lower to mid 50s north to upper 50s south central. Should be ideal radiational cooling conditions under high pressure with clear skies and light winds across all but maybe far south where there could be some lingering clouds from Plains system. Went on the lower end of model guidance with min temps ranging from the upper 20s western interior to upper 30s and lower 40s at many Great Lakes shoreline locations.
We remain well north of a warm front that seems to be draped across Central Alabama, per latest VAD wind profiles from HTX and BMX radars. This would match up well with the low clouds and showers across the northern half of Alabama. This warm front, as part of a developing weather system to our west, will pull northward over the next several hours, increasing shower coverage throughout the morning.
Southwest flow aloft will draw warmer air into the region, resulting in near-normal high temperatures. A cold front located off the PacNW coast this morning will move through SE Oregon late tonight and SW Idaho on Wednesday. An upper trough will then approach the area for a chance of showers in portions of SE Oregon and the northern high terrain of SW Idaho Wednesday afternoon. Temperatures will be 10-15 degrees cooler at most locations.
344 AM MDT Tue Oct 10 2017 Upper level analysis has cut-off closed low over Kansas with ridging building across the northern Rockies. At the surface, high pressure is located across the eastern Dakotas into Minnesota, with a weak lee trof developing across central Montana. Warmer air aloft will continue to build in today and Wednesday, eventually allowing for a warming trend into midweek.
1053 PM PDT Mon Oct 9 2017 Dry weather will linger over the area into Tuesday as a ridge of high pressure remains in place. By Tuesday night and Wednesday, an upper level trough of low pressure settles over the region. This will bring cooler and showery conditions to the Inland Northwest for the rest of the work week. Trends show temperatures cooler for many locations compared to last night.
Today Through Wednesday Night Upper low and cold front continue approaching this morning and mosaic radar showing ongoing line of convection in far eastern OK as of 830Z. Drier and cooler air will begin filtering in through the day today, especially across the western half of the area. By tonight, some higher elevation areas will drop into the low 40s with all areas finally seeing the cooler, post- frontal air before daybreak Wednesday.
1201 AM CDT Tue Oct 10 2017 Main forecast concerns center around precipitation and potential for freezing temperatures in our northern counties. Ahead of the mid-upper low, large-scale forcing for ascent will continue to increase. It may take a while to saturate in the lower levels with prevailing low-level northeast flow, but point forecast soundings indicate the better low-level moisture arrives tonight. thinking the other counties that were previously in the watch will remain warmer under cloud cover.
For the rest of today and tonight, a 500 hPa closed low currently over KS will lift northeastward, nearing the IA/IL border by 06Z Wednesday. The upper low quickly swings east and weakens heading across the Great Lakes on Wednesday with southwest flow aloft developing in its wake as longwave troughing overspreads the Pacific Northwest.
Further east, temperatures will moderate into the low 70's under southwest flow aloft.
A few isolated showers/storms remain present across SW Georgia and the eastern FL Big Bend, but otherwise dry conditions are expected tonight as instability decreases and an upper level ridge remains in place over our area. As a result, the mid to upper level ridge centered off the southeast U. At the surface, a weak cold front will approach and move into our forecast area by late Wednesday. Temps will continue to be well above normal for mid october with highs around 90 and lows in the lower to mid 70s.
Clouds however, were on the increase over the top of the high pressure and across the area thanks to a southwest flow at 700mb and 700-500mb mean RH is greater than 70 percent. With the high pressure expected to be overhead tonight, a light wind and a clear or clearing sky, a widespread freeze is expected. The high will remain overhead through Tuesday.
We'll start to warm up again today with a quick ridge of high pressure and gusty east winds. High pressure will then slowly push temperatures back well above average later in the week. The warming trend will halt by later this week as strong high pressure develops downstream through eastern states and a deep trough pushes through western states. We probably won't see enough moisture for any significant shower chances, but we will see more breeziness under the trough and it should cap off our warming trend around 4 to 6 degrees above average for mid Oct.
146 AM EDT Tue Oct 10 2017 A front slowly crosses midweek, then dry and warm high pressure dominates last half of the week.
318 AM PDT Tue Oct 10 2017 The warmest day of the next 5 or 6 days is expected today as gusty southwesterly winds develop ahead of an approaching cold front.
356 AM EDT Tue Oct 10 2017 High pressure. Will keep the highest pops across the north today since the models seem to favor an axis of higher moisture from southwest to northeast across the state.
313 AM CDT Tue Oct 10 2017 As the trough over the Plains moves off to the northeast, upper level flow will become more zonal before ridging builds in as the high over the southeast builds west.
Frontal boundary was from west central MO to near Wichita, KS as of 2 pm, with much drier and cooler air behind the front. Warm conditions are expected, especially over the eastern Ozarks with cloud cover and southeast wind ahead of the low and front. Any storms that redevelop should exit the area by Tuesday evening with cooler and drier air moving into the region.
335 AM EDT Tue Oct 10 2017 High pressure extending over the area will weaken today as a cold front approaches from the west.
435 AM CDT Tue Oct 10 2017 (Today and Tonight) The cold front has moved south of the area, and continues to move south through the Hill Country.
404 AM EDT Tue Oct 10 2017 High pressure will continue to ridge into the area from the Atlantic through Wednesday.
327 AM CDT Tue Oct 10 2017 The entire region is below freezing, with most areas at or below 28F. Highs today should be slightly warmer than yesterday, with near or below freezing temperatures again expected for Wednesday morning (but not as cold as this morning).
123 AM EDT Tue Oct 10 2017 Ridge of high pressure developing over the area will keep southerly flow and mainly diurnal showers and thunderstorms through the middle of the week.
Cooler today, showers in southern sections tonight. Cold front is pushing across se lower MI. Surface ridging extends from the central/northern plains into northern MI, bringing cooler air to the region on a northerly breeze. Low pressure is in sw Mizzou, and will gradually advance up the Ohio Valley tonight. F-gen band of showers is presently well north of the low, from ne Neb thru far se MN. Low pressure will emerge out of the Plains today and pass by to our south across the northern Ohio Valley Wednesday. high pressure will remain anchored to our north.
High pressure will begin to weaken today ahead of the next approaching weather system. This will mainly result in some increase cloud cover and will allow for a slight increase in winds, particularly over the higher terrain and over the Camas Prairie in Idaho.
643 AM EDT Tue Oct 10 2017 Cold front weakens as it enters southeast OH on Wednesday.
Looks like the season ending freezing has finally arrived in Pagosa Springs. Further north, temps have been hovering around freezing and could drop a bit more as the cirrus conts to thin. And that about takes care of the bulk of excitement for the next 36 hours as we see high pressure build over the forecast area today. This transitory ridge shifts east into the plains this evening with dry southwest flow becoming established. This will drive a little more wind into the region, especially for the higher elevations by Wednesday.
Models are showing a weak shear axis trough mainly aloft this evening. 19z regional analysis reveals an elongated ridge of high pressure in the mid and upper levels extending from the eastern Gulf into the western Atlantic off of the Mid Atlantic Coast. Anticyclonic flow around this high is responsible for the advection of subtle vort maxes around the southern and western periphery into the Southeastern US. In the lower levels. subtle troughing stemming from the remnant low of Nate /currently moving into New England/ along with steady advection of a tropical/ Gulf moisture-rich southerly flow around the Bermuda sfc anticyclone will promote weak convergence and humid conditions. mid/upper ridge will retrograde slightly west into the Southeast. next cold front will be approaching the area from the west.
The long awaited cold front will progress through the Midsouth this evening, putting an end to precipitation chances and sending temperatures and humidity plummeting.
402 AM EDT Tue Oct 10 2017 Cold front weakens as it enters southeast OH on Wednesday.
332 AM EDT Tue Oct 10 2017 High pressure will build into the region today with continuing mild temperatures for October.
207 AM EDT Tue Oct 10 2017 High pressure will ridge southeast into the region from the Upper Great Lake tonight and Tuesday.
Cold front is still draped across parts of the Hill Country but it is making its way southward. Cold front will continue to move southward across the state this evening, and will move through the area early Tuesday morning. The corresponding cold front is expected to move across the CWA/MSA Tuesday.
A trailing cold front will extend south of the low and we expect the front to pass east of the cwfa by midday/early afternoon. Wed-Sat: Our cool down will be fairly short lived as an upper level ridge builds back into the Midwest/Mid-South region Wed/Thu.
Temperatures (which have already dropped into the upper 20s and lower 30s for a large portion of the forecast area by 08z this morning) will increase into the lower to middle 50s this afternoon. Another chilly night is expected tonight, with lows again falling into the lower 20s and upper 30s across the Northland. The large high pressure ridge that will dominate the weather for the first half of this week across the western Great Lakes region will move off to the east at the beginning of the extended periods beginning Wednesday night.
332 AM EDT Tue Oct 10 2017 WV imagery and RAP analysis indicated a sw flow aloft across the Upper Great Lakes between a broad ridge centered over the western Atlantic and a trough from Hudson Bay through the nrn plains into the cntrl Rockies. At the surface, Northerly anticyclonic flow prevailed over the nrn Great Lakes as high pressure over the plains builds toward the area. stronger CAA into the west has kept temps in the lower 50s while readings had climbed to around 60 to the lower 60s over the rest of the cwa. Tuesday, High pressure will continue to build into the area bringing another mostly sunny day. However, with 850 mb temps near 0C, temps will remain in the lower to mid 50s.
143 AM EDT Tue Oct 10 2017 High pressure builds tonight. Tuesday should be mostly dry with high pressure in place but clouds will start to spread northward ahead of the next low pressure system, ejecting out of the midwest. This aforementioned low will track across northern Ohio, with the warm front providing for increased rain chances overnight Tuesday. It appears both downsloping southeasterly wind and a dry slot may be limiting factors for QPF outside of the initial warm front surge, but will still maintain likely PoPs, even with low QPF forecast. Rain chances will continue Wednesday night as the flattening trough pushes eastward. Mid level ridging will quickly build for the remainder of the week. Temperatures will continue to run warmer than averages through the period.
200 AM MDT Tue Oct 10 2017 Mid/upper level low is over western KS and in the process of transitioning eastward.
Upper level trough moving along the BC coast toward the Pacific northwest. This should keep temperatures several degrees warmer than last night with lows in the upper 20s and 30s for most locations. The upper trough moves into the Pacific northwest Tuesday accompanied by a cold front. The trough axis will be over the area Wednesday with cold air aloft. Likely the stronger showers will have small hail as the freezing level will be down near 5000 ft. Mid and upper level cloudiness 15-25 kft will continue to stream through the area ahead of an approaching cold front off the BC coast. Overnight winds will be generally light before becoming westerly and breezy during the afternoon in response to an approaching cold front.
