548 PM MDT Sun Oct 8 2017 Potent upper level trough continues to dig south across UT/NV with main vorticity lobe from southwest MT to south central ID.
A cold front will push south through the area later Monday morning through Monday afternoon. If you're on the water on Monday, be alert to a cold front moving south down the shore during the later morning and afternoon. A cold front will push south through the area later Monday morning through Monday afternoon. A cold front will slowly make its way southeast through WI overnight through Monday morning. This is out ahead of an upper trough crossing the northern Plains and central Rocky Mountains. The cooler air and gusty north winds are expected to accelerate down Lake Michigan a little faster than inland, so northeast winds will keep lakeshore areas cooler during the afternoon. Max temperatures will be limited to the mid 60s toward central WI and the lower 70s in southeast WI.
Strengthening southerly low level flow, in response to digging short wave trough translating across the Intermountain West at this time, will draw ample moisture quickly back into eastern Oklahoma and western Arkansas on Monday ahead of approaching cold front.
Moisture continues to stream north across the region as high pressure strengthens to the East/Northeast Tonight.
A potent cold front will sweep through the region tomorrow morning, affecting TAF sites starting around 13Z. /issued 306 PM CDT Sun Oct 8 2017/ The main weather impact this week continues to be the cold front still on track for Monday morning. Also, a sharp trough will move across the Texas Panhandle on Monday evening.
CC Scattered rain and snow showers will dissipate overnight, as high pressure builds over the region.
639 PM CDT Sun Oct 8 2017 Southwest flow aloft has returned to the area ahead of a deepening upper-level trough positioned over the Northern Rockies.
1102 PM CDT Sun Oct 8 2017 Southwest flow aloft has returned to the area ahead of a deepening upper-level trough positioned over the Northern Rockies.
634 PM CDT Sun Oct 8 2017 A trough of low pressure will dig across the Rockies tonight into Monday. This will keep cooler northerly flow in place across the area through this time.
530 PM MDT Sun Oct 8 2017 The latest water vapor images and RAP analysis had a positively tilted upper trough over the northwestern CONUS with at least a 110 kt jet from KSLC to KINL. Banded rain/snow extended from southwestern WY into north-central SD, with some snow accumulating over the highest Black Hills. The upper low will move to our south on Monday with drier air filtering into the area, and precip coming to an end over southern SD during the morning.
537 PM MDT Sun Oct 8 2017 A developing storm and its cold front will move out of the Northern Rockies and move from north to south across the area tonight and Monday.
A ridge of high pressure will continue to build into the region with mostly clear skies that will allow for good radiational cooling and overnight low temps are expected to fall into the 30s except into the 20s across the higher elevations.
Also, a cold front will move south across West Central Texas during Monday afternoon and be located near the I-10 corridor 10/04Z. Also, a cold front will move south of the I-20 corridor by 10/00Z.
738 PM EDT Sun Oct 8 2017 WV imagery and RAP analysis indicated a mid/upper level trough over the ern CONUS and a trough from nrn Manitoba into the Rockies resulting in sw flow through the plains and nrn Great Lakes. At the surface, a cold front extended from just west of James Bay through wrn Lake Superior. Monday, high pressure building into the area with anticyclonic nrly flow will bring mostly sunny skies and high temps into the upper 50s west and lower 60s southeast. Above normal temperatures will return towards the end of the week ahead of an approaching cold front.
758 PM EDT Sun Oct 8 2017 As remnants of Nate move through the Tennessee Valley and into the Lower Great Lakes by Monday morning, cloud cover will increase this evening. Low temperatures overnight will range from the middle to upper 50s north of Route 24 and into the lower 60s south. Overnight lows will remain mild with most locations staying around 60F (cooler to the NW with less moisture/clouds).
642 PM CDT Sun Oct 8 2017 Cooler temperatures and early week rain chances are the primary forecast concerns. A broad upper trough extending from Hudson Bay southwest into Idaho will continue to pivot east/southeast with a strong 130 kt upper-level jet dropping down the backside of the trough. A closed low is forecast to develop at the base of the trough overnight as it approaches the Four Corners region.
Winds will be southerly tonight, becoming westerly Monday before shifting from the northeast and gusting late in the TAF period behind a strong cold front. Meanwhile an upper low will move across nrn NM Mon with a cold front accelerating swd, especially after 00Z/10 when subsidence arrives in wake of said low as it move INVOF SW KS around 03Z/10. A isallobaric anticyclone looks to be maximized across SE NM/PB/Upper Trans Pecos 00Z/10-03Z/10 and points s after 03Z/10. MOS guidance is emphatic that high wind will occur thru GDP Pass Mon night/Tue AM and the high wind watch there looks good. By next Sat-Sun mid level moisture will have a chance to wrap around the mid level anticyclone to e, especially if timing of a shrtwv trof passing the n is favorable.
834 PM MDT Sun Oct 8 2017 The surface cold front made quick progress south over eastern Utah and northwest Colorado this evening. The upper level low over the western WY/northern UT area will continue dropping south-southeast overnight. Dynamical forcing and ascent ahead of the trough is evident in evening satellite imagery with a plume of colder cloud tops extending from central UT northeast over WY. A developing storm and its cold front will move out of the Northern Rockies and move from north to south across the area tonight and Monday.
Scattered showers/thunderstorms likely by early evening along approaching cold front. Strengthening southerly low level flow, in response to digging short wave trough translating across the Intermountain West at this time, will draw ample moisture quickly back into eastern Oklahoma and western Arkansas on Monday ahead of approaching cold front.
If you're on the water on Monday, be alert to a cold front moving south down the shore during the later morning and afternoon. A cold front will push south through the area later Monday morning through Monday afternoon. A cold front will slowly make its way southeast through WI overnight through Monday morning. This is out ahead of an upper trough crossing the northern Plains and central Rocky Mountains. The cooler air and gusty north winds are expected to accelerate down Lake Michigan a little faster than inland, so northeast winds will keep lakeshore areas cooler during the afternoon. Max temperatures will be limited to the mid 60s toward central WI and the lower 70s in southeast WI.

A broad upper trough extending from Hudson Bay southwest into Idaho will continue to pivot east/southeast with a strong 130 kt upper-level jet dropping down the backside of the trough. A closed low is forecast to develop at the base of the trough overnight as it approaches the Four Corners region.
Winds will increase from the west around 09/15Z and become gusty ahead of a strong cold front set to affect most terminals just after this forecast period. Meanwhile an upper low will move across nrn NM Mon with a cold front accelerating swd, especially after 00Z/10 when subsidence arrives in wake of said low as it move INVOF SW KS around 03Z/10. A isallobaric anticyclone looks to be maximized across SE NM/PB/Upper Trans Pecos 00Z/10-03Z/10 and points s after 03Z/10. MOS guidance is emphatic that high wind will occur thru GDP Pass Mon night/Tue AM and the high wind watch there looks good. By next Sat-Sun mid level moisture will have a chance to wrap around the mid level anticyclone to e, especially if timing of a shrtwv trof passing the n is favorable.
Parts of NPW may be expired from west to east as threat for winds at the highest elevations moves eastward overnight. As of 130 PM EDT Sunday: An amplified upper pattern will be in place Monday night in the wake of Nate's departure, with strengthening high pressure over the southeastern U. and a deep but progressive trough/closed low over the southern plains.
A cold front will continue shifting east through northwest Wisconsin this afternoon and evening. The clearest conditions for the overall night appear to be in north-central Minnesota, where temperatures should drop into the lower 30s.
A cold front will push across northern Arizona overnight. Temperatures will be noticeably cooler on Monday.
1259 AM EDT Mon Oct 9 2017 High pressure offshore will remain in control through Monday, as the remnants of Nate are forecast lift well to the west.
An upper level trough currently over Idaho, will continue pushing southeast tonight. The airmass associated with the high pressure is certainly cold with 925 mb temps in the single digits, or around the 25th percentile. Weak CAA should produce highs only in the upper 40s to the lower 50s.
703 PM CDT Sun Oct 8 2017 A weak ridge of high pressure is draped over the area this afternoon. This ridge is separating tropical depression Nate from a low over the Oklahoma Panhandle. With the clear sky in place and light variable wind over our area between the two low pressure systems, we should see fog develop again tonight.
An upper low is located off the Northern California coast and will move inland across northern California this morning then will shift southeastward. This low will bring some light showers into the area today. An upper level ridge will briefly build into the area this evening and tonight. A trough will move across the region immediately behind this front late Tuesday into Tuesday evening and bring cool showery conditions.
Winds will remain breezy tonight ahead of a cold front that will come through after this period. Strong cold front late tonight and Tuesday morning with sharply colder conditions on Tuesday. Deepening lee trof over eastern New Mexico will produce breezy conditions for the Panhandles today. The ECMWF and NAM have maintained good temporal continuity regarding placement of trof/closed low as compared to runs of 24 hours ago. All models have significantly strengthened this feature, with a more prolonged and deeper closed low now being depicted. The strength of the closed low passing the forecast area on Tuesday leads us to increase winds on Tuesday. Associated strong cold front should move through the Oklahoma Panhandle before dawn Tuesday and then sweep through the rest of the forecast area by 10 AM.
Strong winds will occur over the plains behind a cold front currently moving across the region this morning, while a mix of rain and snow can be expected over southwest Montana through early this afternoon.
1019 AM EST Mon Nov 27 2017 Except for a few light snow showers over Northern NY, building high pressure will bring fair weather to our region for Monday, while a warming trend is forecast Tuesday afternoon. The tail end of a cold front is moving through the area right now and temps are a little cooler than forecast over our northern zones in central NY so adjusted temperatures down over this area for the rest of today. A weak cold front dropping into our northern forecast area will briefly increase snow shower activity early this morning. Building high pressure will clear skies out late today and for tonight. In addition upper atmospheric ridging will move over NY and PA, with the result being much higher-than-normal thicknesses. Temperatures on Tuesday will climb into the lower and middle-50s.
/issued 319 AM EST Mon Nov 27 2017/ Another dry day is in store for us across South Florida starting with a cool morning with temperatures in the low 60s along the e and west coast metro and upper 50s in the interior. High pressure over The Carolinas will move east shifting winds more east to northeast through mid week.
640 AM EST Mon Nov 27 2017 High pressure will build in behind a cold front and give our area mainly clear skies but chilly air today. As the high moves east, milder air return to the region and remain for much of the week. A northwest flow off the lakes will bring a few clouds to the far northern zones this morning, otherwise high pressure will build into the area bringing mainly clear skies. After a chilly start under clear skies, flow becomes southwesterly on Tuesday bringing milder air while ridging keeps the sun shining.
643 AM EST Mon Nov 27 2017 Clear skies this morning will lead to a quick warmup as diabatic heating combines with a deepening boundary layer, tapping into warmer air aloft. The core of surface ridging shifting along the spine of the Appalachians coupled with dry northwest flow will maintain clear skies, aside from a few strands of passing cirrus, and late fall warmth across eastern Kentucky. Continually building upper heights will promote further warming today and Tuesday as eastward drifting surface ridging establishes south/southwesterly return flow.
601 AM EST Mon Nov 27 2017 High pressure in control through mid week.
955 AM EST Mon Nov 27 2017 Dry high pressure will remain over the area into midweek.
422 AM CST Mon Nov 27 2017 Record high temperatures in the 70s are expected today with an upper level ridge over the central plains and southerly surface winds. There will be a rather decent south breeze today as the pressure gradient tightens ahead of an approaching cold front. A cold front will swing through the area tonight and end our flirtation with record highs although the air behind the front will still be mild by late November standards. Highs will be cooler with cold air advection behind the cold front, but this is only a glancing blow at cooler air with highs likely still in the 50s or generally around 10 degrees above normal. There will be a small cut off upper low that will track south of our forecast area Tuesday night bringing rain to portions of Kansas and Oklahoma.
930 AM EST Mon Nov 27 2017 High pressure will dominate the region into Tuesday then shift east to allow a cold front to move through Tuesday night.
Temperatures will reach the upper 60s coast to the lower 70s inland. High pressure will be reinforced to the north with ne winds increasing to around 15 knots by this evening.
/issued 347 AM CST Mon Nov 27 2017/ Upper ridging is over the region with an upper trough over the west coast that will move east today. The base of the upper trough will move over the area beginning tonight. Winds will weaken later Tuesday prior to a cold front moving into the area resulting in cooler temperatures especially across the northern CWA. The upper trough will move over the region quickly so this will not allow any high wind event in the Guadalupe Mountains to last.
637 AM CST Mon Nov 27 2017 Record high temperatures in the 70s are expected today with an upper level ridge over the central plains and southerly surface winds. There will be a rather decent south breeze today as the pressure gradient tightens ahead of an approaching cold front. A cold front will swing through the area tonight and end our flirtation with record highs although the air behind the front will still be mild by late November standards. Highs will be cooler with cold air advection behind the cold front, but this is only a glancing blow at cooler air with highs likely still in the 50s or generally around 10 degrees above normal. There will be a small cut off upper low that will track south of our forecast area Tuesday night bringing rain to portions of Kansas and Oklahoma.
430 AM MST Mon Nov 27 2017 An upper trough will cross the forecast area today with a cold front moving through at the surface this afternoon. The cold front is expected to enter northeastern Wyoming and far northwestern South Dakota shortly after noon, reaching the Black Hills area by mid-afternoon and then moving into Nebraska late this afternoon into early this evening. There is less certainty with high temperatures over the rest of the forecast area this afternoon, especially north of I-90 where the low level cold advection will be strongest.
757 AM EST Mon Nov 27 2017 High pressure will support dry and warm weather through mid week.
630 AM EST Mon Nov 27 2017 Mild, Pacific high pressure will build east across the Carolinas today, then offshore on Tuesday. An area of high pressure at the surface and rising heights aloft will maintain clear skies across central NC through tonight. Low level thicknesses support high temperatures close to normal, generally around 60 north to the lower 60s south. This moderating air mass will translate to afternoon temperatures into the low-mid 60s under sunny skies.
621 AM EST Mon Nov 27 2017 Except for a few light snow showers over Northern NY, building high pressure will bring fair weather to our region for Monday, while a warming trend is forecast Tuesday afternoon. A weak cold front dropping into our northern forecast area will briefly increase snow shower activity early this morning. Building high pressure will clear skies out late today and for tonight. In addition upper atmospheric ridging will move over NY and PA, with the result being much higher-than-normal thicknesses. Temperatures on Tuesday will climb into the lower and middle-50s.
958 AM CST Mon Nov 27 2017 High pressure centered over the Tennessee Valley will move east today with low level southerly winds allowing temperatures to warm to several degrees above average.
As the cold front crosses the Northern Rockies this morning, snow levels have been lowering to mountain pass level, causing light snow accumulations to occur on roadways. Moisture may eventually overcome these winds and make it down to the surface later today, but seeing as how this is a quick cold frontal passage, most of the precipitation will end by that time.
Dry and much cooler conditions will prevail the rest of the week with dense fog possible in the San Joaquin Valley. Cold frontal band with moderate to locally heavy precipitation is pushing in over the SF Bay area and will track east into the San Joaquin Valley and Sierra this morning. Short wave ridging moves over Monday night and Tuesday followed by a dry trough midweek. Temperatures will be much cooler than the last several days.
629 AM EST Mon Nov 27 2017 Dry high pressure will build over the area into the middle of the week.
944 AM EST Mon Nov 27 2017 Most inland areas saw temperatures drop into the 30s overnight with a few locations reporting lows near or just below the freezing mark. Temps will warm into the upper 60s to the lower 70s this afternoon under sunny skies.
615 AM EST Mon Nov 27 2017 High pressure continues to build in from the west today. The high will slowly shift off the coast Tuesday.
1053 AM EST Mon Nov 27 2017 Dry high pressure will build over the area into the middle of the week.
552 AM EST Mon Nov 27 2017 Dry high pressure will build over the area into the middle of the week.
Seasonable warmth will continue through the day as ridging in the Plains ushers warm air into the state. An advancing upper level trough/surface front will temper 850MB temperatures through the afternoon though surface temperatures will lag. Generally cooler conditions are expected with lows in the upper 20s and lower 30s; still above average. Tuesday will bring cooler weather with highs mostly in the 40s in western and central areas. A cold front will move southeast across North Dakota today.
918 AM EST Mon Nov 27 2017 Dry high pressure will build over the area into the middle of the week.
Strong cold front late tonight and Tuesday morning with sharply colder conditions on Tuesday. Deepening lee trof over eastern New Mexico will produce breezy conditions for the Panhandles today. The ECMWF and NAM have maintained good temporal continuity regarding placement of trof/closed low as compared to runs of 24 hours ago. All models have significantly strengthened this feature, with a more prolonged and deeper closed low now being depicted. The strength of the closed low passing the forecast area on Tuesday leads us to increase winds on Tuesday. Associated strong cold front should move through the Oklahoma Panhandle before dawn Tuesday and then sweep through the rest of the forecast area by 10 AM.
929 AM EST Mon Nov 27 2017 High pressure in control through mid week.
345 AM MST Mon Nov 27 2017 An upper trough will cross the forecast area today with a cold front moving through at the surface this afternoon. The cold front is expected to enter northeastern Wyoming and far northwestern South Dakota shortly after noon, reaching the Black Hills area by mid-afternoon and then moving into Nebraska late this afternoon into early this evening. There is less certainty with high temperatures over the rest of the forecast area this afternoon, especially north of I-90 where the low level cold advection will be strongest.
359 AM MST Mon Nov 27 2017 Broad ridging extends across the Central US, with a deepening upper level trough along the Pacific coast. ML winds behind the cold front would support gusts 40-45 mph.
915 AM EST Mon Nov 27 2017 High pressure continues to build in from the west today. The high will slowly shift off the coast Tuesday.
/ISSUED 303 AM CST Mon Nov 27 2017/ High pressure over the mid Tennessee valley continues to ridge into SE TX bringing drier air and clear skies to the region. The high will move east today and E-SE winds will develop and bring slightly higher moisture levels back to the area tonight and Tuesday. High moisture levels on Tuesday should yield more cloud cover but warmer 850 temps and increasing heights will yield slightly warmer temperatures.
A fast moving cold front will bring strong winds and cooler temperatures to the region today.
957 AM EST Mon Nov 27 2017 High pressure will build overhead today and move to the east by Tuesday.
452 AM MST Mon Nov 27 2017 Broad ridging extends across the Central US, with a deepening upper level trough along the Pacific coast. ML winds behind the cold front would support gusts 40-45 mph.

1008 AM EST Mon Nov 27 2017 Mild, Pacific high pressure will build east across the Carolinas today, then offshore on Tuesday. -Ellis An area of high pressure at the surface and rising heights aloft will maintain clear skies across central NC through tonight. Low level thicknesses support high temperatures close to normal, generally around 60 north to the lower 60s south. This moderating air mass will translate to afternoon temperatures into the low-mid 60s under sunny skies.
1139 AM CDT Mon Sep 4 2017 Cold front extended from southeast Iowa into northwest Missouri late this morning. Do not expect much activity along the fnt, other than cooler temps and some clouds, until late this afternoon. While storm motion shud be ESE, development shud spread swwd with the approach of the upper trof and low level cooling. Prev mdl solns suggested a frontogenetical band of precip behind the fnt as the main trof digs into the area.
Forecast highlights in the short term period will be cooler temperatures and gusty winds. Currently, strong northwest flow aloft between a persistent ridge of high pressure across the western U. and deep low pressure over Hudson Bay.
