907 AM MST Thu Nov 10 2016 Ridge of high pressure in control for a very sunny Fall day today. Weak cold front will slip through the CWA early this morning (currently positioned from Livingston to near Roundup moving S/SE) with a northerly wind after daybreak. This will shift to a northeast wind for much of the area by late morning resulting in cooler conditions than yesterday.
Upper low pressure system over West Texas will continue to provide high level cloud cover as it remains out to the West. /issued 409 AM CST Thu Nov 10 2016/ While cooler and drier air continues to backdoor SW into the region this morning ahead of sfc ridging over OK/AR. the IR satellite imagery depicts an extensive area of cirrus quickly spreading NE across E TX/Wrn LA ahead of the broad upper low that has retrograded W into Nrn MX. With the reinforcement of the cooler/drier air mass into the area.
Will maintain considerable cirrus as an upper low positioned over northern old Mexico transports Pacific moisture northeast into the area. but building high pressure to our north will relax the gradient by late afternoon. A cool ridge of high pressure is settling over the Southern Plains and the Lower MS Valley this morning. Aloft, an upper low remains over Northern Mexico with the southern stream of the jet just south and east of the CWA. Today and Friday, temperatures will be near climo values and weakening CAA will continue as the ridge continues to build in.
218 PM CST Thu Nov 10 2016 1027 mb high pressure over central Texas and ridging northeast into KY/WV was providing a sunny, breezy and seasonably mild afternoon across central IL. A cold front extended from nw parts of IA/WI into nw KS. Nearby high pressure aloft and at the surface was giving sunny skies across IL and Midwest today. Latest forecast models sweep the cold front southeast across central IL later this evening and thru southeast IL overnight. Winds could be gusting 15-25 mph on Friday and bringing in cooler air. Lows overnight will be mostly in the lower 40s. Highs Friday range from the low to mid 50s from I-72 north to the upper 50s to near 60F in southeast IL.
1245 PM EST Thu Nov 10 2016 High pressure along with cooler and drier air will continue building into the region today and Friday. Another cold front will cross the region Friday night with limited moisture and cloudiness expected.
Cool conditions exist this morning thanks to the cold front that pushed through yesterday. This is generally around 6 to even 12 degrees cooler than 24 hours ago. Pleasant fall- like conditions will occur today with highs eventually reaching the lower 70s under sunny skies.
334 PM CST Thu Nov 10 2016 Low clouds have slowly been expanding northward through the day which has held temperatures in the low to mid 50s across the southwestern South Plains while areas that have seen sun all day are in the low 70s, mainly in the northern Rolling Plains. The low clouds are expanding northward as the upper-level low remains entrenched over northern Mexico and as surface winds have swung to the southwest helping to keep low-level moisture in place as well. Cannot see any reason that the cloud cover will erode through the night so low temperatures will once again be relatively warm under the clouds and a bit cooler wherever skies can remain clear.
126 PM EST Thu Nov 10 2016 High pressure today. A mostly dry cold front crosses Friday, with much cooler air for the weekend.
A secondary cold front dropping through southern Mb/Ontario will clip nw Mn overnight bringing another shot of cold advection to this area. High pressure centered over the fa Friday morning will shift east during the day with some weak return flow/warm advection mainly from the valley west. With cooler thermal profile temperatures will be much closer to seasonal averages but still on the warm side of averages.
These are associated with an upper level speed max moving around an upper low centered near El Paso, which may provide enough lift to allow a few showers to move into the offshore coastal waters later this afternoon. /ISSUED 336 AM CST Thu Nov 10 2016/ The upper low was located in northern Mexico just south of the AZ/NM border. Over the next few days, the upper low will begin to fill. The models show the low beginning to open up on Friday and then shear out as it moves eastward across the Southern Plains over the weekend.
South winds should increase significantly Friday ahead of a fairly strong cold front.
The region remains nearly cloud-free this afternoon, with clouds increasing from north to south overnight as a cold front crosses the region late tonight into Friday. Sprawling high pressure will push southeast Friday evening, quickly drying out any remaining moisture and therefore bringing an end to remaining showers and clouds.
The cold front will pass southeast through the area by early this evening. Strong cold air advection tonight into Friday will bring much cooler, but more seasonable, temperatures into the area.
1243 PM EST Thu Nov 10 2016 High pressure over the Ohio Valley will slide off to the south today providing an increasing southwest flow and warmer temperatures. A cold front will drop across the area later tonight and bring colder air again on Friday. High pressure will build across the lower Great Lakes and Ohio Valley this weekend. Will forecast the high end of the max temperature guidance given the upstream temperatures yesterday in the same air mass. Highs near 60 or in the lower 60s. The models continue to trend somewhat faster with the cold front tonight with a frontal passage between midnight and before daybreak from north to south.
932 AM PST Thu Nov 10 2016 High pressure aloft and weak Santa Ana winds will produce warm and dry weather again today, with locally gusty winds in the coastal foothills and much above normal temperatures in the coast and valleys.
TFJ Upper ridging today into Friday will make for temperatures 10-15 degrees above normals.
308 PM EST Thu Nov 10 2016 Currently - Broad high pressure over the southeastern United States is spreading eastwards into the Atlantic, filling in behind a departing mid latitude low. Deep layered ridging continues to build northward through the eastern Gulf of Mexico, keeping conditions unfavorable for shower development. Forecast - Light northeast breezes will gradually become more easterly heading into the weekend as the high pressure system to our north continues to stretch eastwards and settle southwards. The high cell will be reinforced by a strong high shifting southeastwards into the eastern United States.
Approaching dry cold front will move across the Northern portions of the area by Friday morning.
Highs will be in the low to mid 70s. A quiet pattern will continue as a deep upper level trough moves off to our east, replaced by a broad ridge today. 5" across our area, and high pressure will continue to dominate at the surface. Light northerly flow will continue to advect cooler air into our region, resulting in inland lows dipping into the 40s by the early morning, and 50s near the coast.
The large upper level low continues to spin nearly stationary to our west. The main story in the short-term forecast will be the continued cloud cover and cooler temperatures.
232 PM CST Thu Nov 10 2016 Initial cold front or wind shift line moved across central and southern Minnesota this afternoon. A secondary cold front and associated short wave, was evident across northern Manitoba this afternoon. Highs tomorrow will be closer to normal with readings in the low to mid 40s.
Low level high pressure centered over the ArkLaTex will slide eastward through tonight, allowing our light winds from the east to go calm overnight.
133 PM CST Thu Nov 10 2016 Surface analysis this afternoon features a cold front dropping through the region. This cold front has no moisture to work with, so coming through cloudless and dry. Quiet/dry/cooler weather on tap for Friday/Friday night as Canadian high pressure drops through the region. Ideal radiational cooling setup for Friday night with ridge overhead/clear skies/very light/calm winds.
114 PM EST Thu Nov 10 2016 High pressure centered to the southwest will keep dry weather over the region today. A cold front will cross the area early Friday, followed by more high pressure and dry air for the weekend.
1216 PM EST Thu Nov 10 2016 High pressure will build in from the west today and slide to the south tonight.
The ridge of high pressure will remain in place for one more day, which will translate to another foggy morning on Friday for many valleys across western Montana and north- central Idaho.
214 PM EST Thu Nov 10 2016 High pressure will continue to build into the region through Friday. A cold front with limited moisture will cross the region Friday night, ushering in dry and much cooler weather for the weekend.
Closed low spinning stationary near the New Mexico bootheel, with any clouds associated with the cyclonic circulation remaining to our south. Comfortable temperatures in the lower 70s this afternoon, courtesy of downslope prefrontal compression and SW winds of 10-20 mph. A dry cold front passage is expected across SW KS tonight. After several hours of light and variable winds this evening, winds will becoming NE and increase in velocity behind the cold front overnight. We will see cooler temperatures for Friday in the wake of the front.
102 PM EST Thu Nov 10 2016 High pressure over the Ohio Valley will slide off to the south today providing an increasing southwest flow and warmer temperatures. A cold front will drop across the area later tonight and bring colder air again on Friday. High pressure will build across the lower Great Lakes and Ohio Valley this weekend. Will forecast the high end of the max temperature guidance given the upstream temperatures yesterday in the same air mass. Highs near 60 or in the lower 60s. The models continue to trend somewhat faster with the cold front tonight with a frontal passage between midnight and before daybreak from north to south.
134 PM PST Thu Nov 10 2016 High pressure aloft and weak Santa Ana winds will produce warm and dry weather again today, with locally gusty winds in the coastal foothills and much above normal temperatures in the coast and valleys.
High pressure ridge well north of Florida will keep conditions dry over the next 24 hours.
Tonight Through Friday High pressure will continue to dominate the weather across western and central Wyoming through Friday with dry and unseasonably mild weather.
/28/ Cool conditions exist this morning thanks to the cold front that pushed through yesterday. This is generally around 6 to even 12 degrees cooler than 24 hours ago. Pleasant fall- like conditions will occur today with highs eventually reaching the lower 70s under sunny skies.
An upper level ridge of high pressure over the region today will allow for sunny skies, light winds and mild temperatures. Central and Southwest Montana are under a high pressure ridge which will keep the air mass dry and stable.
These clouds are associated with a pocket of warm and moist air aloft and within a small scale wave trailing the upper low. Light north to northeast wind will follow the trough passage along with an improving trend in visibility/ceiling during late morning through afternoon. Upper level low pressure system will finally shift east of the area late today into tonight. Would expect fog/stratus to be most prevalent Monday morning as surface ridging will be overhead with basically calm winds as a result.
Weak low pressure aloft will continue over the area through Monday. Another low pressure system will bring an increased threat of showers to the region Monday and Monday night.
748 PM EDT Sun Oct 2 2016 An upper level area of low pressure will move slowly through New York overnight and Monday keeping clouds and a chance of showers in the area.
643 PM CDT SUN OCT 2 2016 Large closed low in the mid levels continues over the Great Lakes region with ridging over the nation's mid-section. Additionally, another deep trough over the Pacific is crashing into the ridge, which will lead to the pattern's shift toward the east. In the short term, the main change will be for temperatures to be slightly warmer with additional moisture moving into the region, with winds increasing from the south. Isentropic lift will develop late in the day Monday, with some storm confined main along the trough, which is expected to be located out across the High Plains.
1040 PM EDT Sun Oct 2 2016 An upper level low pressure system will move slowly through central New York overnight and Monday keeping clouds and scattered showers over the area.
841 PM EDT Sun Oct 2 2016 Upper level low pressure will maintain shower chances this evening. High pressure will then build overhead through the middle of the week. Closed low centered near Lake Erie will continue to shift east through Monday with scattered showers and possibly an isolated thunderstorm into early evening. Only isolated showers possible north of I-80 Monday closer to exiting upper trough, otherwise dry with not as much cloud cover Monday afternoon.
913 PM EDT Sun Oct 2 2016 Low pressure over the eastern Great Lakes will slowly lift northeastward into eastern Canada through Monday. A trough axis will cross the region this evening. Behind the trough, high pressure will then build southward into the region during the middle portion of the week. Tropical cyclone Matthew could be a factor in our weather by the end of the week. Upper level low still churning over the eastern Great Lakes this evening is keeping the area in broad southwest flow aloft with areas of mid level clouds and even an isolated shower or two out there. Lows from the lower 50s to lower 60s.
1131 PM CDT Sun Oct 2 2016 For tonight, upper ridge will begin to build into the area from the west and on Monday should start to see decent warm air advection begin, especially over the western CWA.
1023 PM EDT Sun Oct 2 2016 Pesky upper level low currently centered over western Lake Ontario per satellite imagery will continue to slowly move away to the east overnight. High impact weather potential: None Upper low continues to spin near MI today with large ridge across the Plains and upper Midwest. low pressure moving relatively quickly to the east over Lake Huron. especially in the lower levels. Strong high pressure moving across Ontario and Quebec keeps a moist easterly low level flow over the region through Monday. cooler in the UP where there should be some breaks. We will be saying good riddance to the pesky upper level low that has plagued our weather for the last several days, to be replaced with upper level ridging building directly overhead to start the new work week.
724 PM EDT Sun Oct 2 2016 Low pressure will move across New York tonight and Monday bringing cloudy skies and a chance of light rain showers and even a slight chance of thunder to northern New York overnight.
1023 PM CDT SUN OCT 2 2016 Forecast remains on track with surface and upper-level ridge building in from the west.

Warm air advection will increase Monday ahead of the incoming front as ridging builds over the Plains. Portions of NW Arkansas may see some patchy fog develop by morning, especially in the lower valleys, but should quickly dissipate.
1151 PM CDT SUN OCT 2 2016 Large closed low in the mid levels continues over the Great Lakes region with ridging over the nation's mid-section. Additionally, another deep trough over the Pacific is crashing into the ridge, which will lead to the pattern's shift toward the east. In the short term, the main change will be for temperatures to be slightly warmer with additional moisture moving into the region, with winds increasing from the south. Isentropic lift will develop late in the day Monday, with some storm confined main along the trough, which is expected to be located out across the High Plains.
836 PM EDT Sun Oct 2 2016 Upper level low pressure will maintain shower chances this evening. High pressure will then build overhead through the middle of the week. Closed low centered near Lake Erie will continue to shift east through Monday with scattered showers and possibly an isolated thunderstorm into early evening. Only isolated showers possible north of I-80 Monday closer to exiting upper trough, otherwise dry with not as much cloud cover Monday afternoon.
However, the main upper level trough axis associated with the low over the Great Lakes is still to our west. There may be just enough lift with this feature to allow for some cloud cover tonight, which may help to keep temps a degree or two warmer than yesterday evening. Dewpoints have increased into the lower 50s for much of the area and we could see patchy fog again tonight.
Short wave trough has moved through the forecast area and off to the east. /issued 337 PM CDT SUN OCT 2 2016/ Mid-afternoon sfc analysis shows high pressure centered nearly overhead. Water vapor imagery shows lows located over the Great Lakes and Pacific NW while ridging lies in place between them over the cntl CONUS. Deepening cyclone over the Pacific NW will also nudge the mid/upper-level ridge ewd. Main effects of all this appears to be warmer mins and maybe a little higher humidity tomorrow.
The forecast should allow for another 24 period of vfr weather as the Eastern Lakes Upper low drifts farther east through the Northeastern U.
951 PM EDT SUN OCT 2 2016 High pressure moves in tonight and stays through mid week. Therefore, will go on the lower side of MOS guidance for lows tonight in the northwestern counties were skies should clear, but will go with the warmer NAM MOS in areas where clouds should remain late in the night. High pressure then builds in and provides dry weather for Monday.
The upper level low, currently over northern California, will continue east along the northern Nevada border tonight and into Eastern Idaho/Northern Utah through early Monday. Clouds beginning to fill in from the south ahead of the low which should help keep temperatures near normal Monday Morning. Do expect isolated showers assoiciated with the low center across Southeast oregon and along the Nevada border Monday morning. The low center will push east into Eastern Idaho/Western Wyoming early Monday afternoon which will bring gusty west-northwesterly winds to much of the forecast area.
751 PM EDT Sun Oct 2 2016 An upper level low will cross the region tonight into Monday. A weakening upper level low will begin to cross the region tonight. The CWA will be the battle ground over the next 24 hours between a weakening upper level low and dry Canadian air trying to invade from Quebec province. Low level clouds will hang on across Bangor and Downeast through noon tomorrow, but drier air will push the clouds out of northern Maine Monday morning as a back door cold front pushes in much drier air. Temps will run near average on Monday, expecting cold temps Monday night as clear skies, dry air, and high pressure located directly overhead will allow for strong radiational cooling. As stated well by the midnight crew, a powerful ridge of high pressure will build across the region.
1218 AM EDT Mon Oct 3 2016 An upper level low will cross the region overnight into Monday. The CWA will be the battle ground over the next 24 hours between a weakening upper level low and dry Canadian air trying to invade from Quebec province. Low level clouds will hang on across Bangor and Downeast through noon tomorrow, but drier air will push the clouds out of northern Maine Monday morning as a back door cold front pushes in much drier air. Temps will run near average on Monday, expecting cold temps Monday night as clear skies, dry air, and high pressure located directly overhead will allow for strong radiational cooling. As stated well by the midnight crew, a powerful ridge of high pressure will build across the region.
711 PM CDT SUN OCT 2 2016 Manual analysis of 12z upper-air data revealed a mid-level trough moving onto the West Coast, downstream ridging from the central Plains into western Ontario and a closed low over the lower Great Lakes. The aforementioned mid-level trough will progress through the Interior West tonight before emerging into the northern High Plains on Monday. The surface cyclone attendant to this system will deepen over the northern High Plains during that time frame while a trailing Pacific front moves into the central High Plains. Tomorrow's high temperatures will be warmer than today, though increasing high-level cloudiness may limit our maximum heating potential.
1058 PM EDT Sun Oct 2 2016 An upper level low will cross the region overnight into Monday. A weakening upper level low will begin to cross the region overnight. The CWA will be the battle ground over the next 24 hours between a weakening upper level low and dry Canadian air trying to invade from Quebec province. Low level clouds will hang on across Bangor and Downeast through noon tomorrow, but drier air will push the clouds out of northern Maine Monday morning as a back door cold front pushes in much drier air. Temps will run near average on Monday, expecting cold temps Monday night as clear skies, dry air, and high pressure located directly overhead will allow for strong radiational cooling. As stated well by the midnight crew, a powerful ridge of high pressure will build across the region.
948 PM EDT SUN OCT 2 2016 Low pressure over Western Lake Ontario will drift off the Mid Atlantic coast and dissipate Monday.
755 PM MST SUN OCT 2 2016 A low pressure system moving through the Great Basin tonight and Monday will bring a cold front through the Desert Southwest.
708 PM EDT SUN OCT 2 2016 Late afternoon/early evening coverage of showers remains on the low side as diurnal heating diminishes with sunset. Expect some combination of the two as good radiational cooling sets up prior to a trough settling southward from northern lower Michigan. It could disrupt visibility restriction unless denser fog can develop before the trough and associated clouds arrive. Light north to northeast wind will follow the trough passage along with an improving trend in visibility/ceiling by Monday afternoon. Upper level low pressure system will finally shift east of the area late today into tonight. Would expect fog/stratus to be most prevalent Monday morning as surface ridging will be overhead with basically calm winds as a result.
BMickelson Previous short term discussion: An upper trough on the western U. Models continue to suggest potential for a dry slot over the eastern zones late Monday as the trough pushes east which could allow for brief sunshine.
617 PM CDT Sun Oct 2 2016 Upper low has started to lift northeast after sitting in the OH valley for several days. For tonight, upper ridge will begin to build into the area from the west and on Monday should start to see decent warm air advection begin, especially over the western CWA.
47 Upper ridging passing across Texas. creating mainly clear evening skies with surface ridging producing a near calm wind field. Weak upper level diffulence just upstream of a north central Gulf jet level trough has kept mainly scattered showers over our western waters.
801 PM EDT Sun Oct 2 2016 High impact weather potential: None Upper low continues to spin near MI today with large ridge across the Plains and upper Midwest. low pressure moving relatively quickly to the east over Lake Huron. especially in the lower levels. Strong high pressure moving across Ontario and Quebec keeps a moist easterly low level flow over the region through Monday. cooler in the UP where there should be some breaks. We will be saying good riddance to the pesky upper level low that has plagued our weather for the last several days, to be replaced with upper level ridging building directly overhead to start the new work week.
