145 PM CDT Sun Oct 9 2016 144 PM CDT No real big weather concerns tonight as high pressure remains overhead. High pressure will begin to shift to the east tonight while low pressure takes shape over the Plains, allowing for a transition towards a south southeast wind direction.
/issued 1004 AM CDT SUN OCT 9 2016/ Cold front well out into the gulf as Ci drifts across the region this morning. High pressure will continue over the forecast area through the period. /issued 322 AM CDT SUN OCT 9 2016/ The cold front is now well south and east of the forecast area.
This along with light to calm winds will allow temps to drop into the lower 50s inland and mid to upper 50s along the coast.
Light winds can also be expected throughout the upcoming forecast period with winds veering from north to northeast to southeast with time as the center of this high shifts slowly east. Water vapor imagery shows upper ridging sliding into the area behind the exiting trough. Temperatures last night were solidly in the 30s, and expect to see temps near to slightly cooler than that tonight. With slightly cooler temperatures and better radiational cooling, we should see frost become more widespread. The upper ridge will amplify Monday into Monday night as it moves slowly east into New England. This will be in response to the upper trough dropping southwest out of western Canada. High pressure will remain in control tomorrow to provide a dry day, but temperatures will be slow to respond to warming aloft as inversion heights remain low and mixing is limited.
226 PM EDT Sun Oct 9 2016 Canadian high pressure will build across the northern Mid- Atlantic tonight and Monday before shifting offshore during the middle of the week.
A weak front that extended from north fl southwestward across the Gulf this morning will dissipate as high pressure builds into the region. This high will usher in some drier and cooler air on northeasterly winds. Building high pressure will provide northeasterly winds that increase tonight into caution or advisory speed.
The short wave trough currently over the 4-corners region will track across southeast Colorado and into western Kansas this evening and into north central Kansas by Monday morning.
1159 AM MDT Sun Oct 9 2016 An upper trough over northern AZ will gradually slide northeast and over the area today and tonight. The moisture and lift associated with the trough will move east of the area tonight with just a few lingering showers over the mountains near the Continental Divide south of Interstate 70. By Monday morning, the wave mentioned above will have shifted to the east but little reprieve as an elongated trough starts to drop down from the Pacific Northwest. Ahead of this trough, a 90kt jet streak will set up over the area.
High pressure over the region will continue to keep temperatures above normal with highs in the upper 80s to around 90 today in the valley.
245 PM CDT SUN OCT 9 2016 WV imagery shows the upper trough centered over NW NM/SW CO, and poised to pass north of West Texas and Southeast New Mexico overnight. Otherwise, after tonight's trough passes, zonal flow aloft develops over the region as an upper ridge develops over Mexico and South Texas the next few days.
433 PM CDT Sun Oct 9 2016 High pressure on the surface and aloft dominating the weather pattern, resulting in dry conditions and cooler temperatures, over the Four State Region.
153 PM MDT Sun Oct 9 2016 Latest upper air analysis shows a closed low approaching the Pacific Northwest with another weaker trough over the Desert Southwest and a ridge was over the plains. Chances for rainfall do not look as promising as this time yesterday due to the upper level short wave trough tracking just south of the Tri-State Area. Tonight the short wave trough and associated lift remain mostly south of the Tri-State Area, although the southeast fringe may be grazed by some rainfall activity as the storms track eastward.
Drier air is filtering into the area as high pressure ridge builds south from the Great Lakes. Temps will range from the lower 70s along the immediate coast (beachside) to the lower 60s far interior (Lake county).
Under starry skies and a near calm wind field, Monday morning interior temperatures will dip into the lower 50s with isolated spots flirting with the upper 40s (last upper 40 degree minimum temperature in Conroe was on May 4th).
1203 PM CDT SUN OCT 9 2016 High pressure continues to dominate the region this morning. although this high will shift eastward over the coming day to allow a more southerly flow to develop and allow increasing high clouds in the afternoon and overnight. although a weak cold frontal boundary settling down from the north may bring some north or northeast directions this afternoon or evening along/north of I-74 as the front pushes into this region and stalls out.
Clearing skies early Monday will promote faster warming, and temperatures reaching the low 80s by the early afternoon.
315 PM EDT Sun Oct 9 2016 High pressure building down from Canada will bring cooler temperatures to New York and Pennsylvania through Monday.
Otherwise, VFR under high pressure, with dry conditions.
158 PM EDT Sun Oct 9 2016 Post-tropical storm Matthew passes well south and east of the region today as high pressure starts to build in from the west.
A well defined upper low moving into Colorado is resulting in pronounced subsident flow into Arizona today. Residual low level moisture across Arizona along with strong insulation today should be enough to overcome the increasing subsidence aloft to allow for a few showers and thunderstorms over the high terrain mostly east of Globe and along the Mogollon Rim. There are a few showers and thunderstorms already forming in the White Mountains as of 20Z and some towering Cu all along the Mogollon Rim and some over the higher peaks of southern Gila county.
Water vapor showing large upper level trough over BC extending off the coast. A strong short wave rotating through the trough will cross the region tonight pushing the frontal boundary and rain south into Oregon.
307 PM EDT Sun Oct 9 2016 Nice quiet fall like weather pattern will persist through the short term as high pressure remains parked over the eastern third of the country. The cool dry air mass will result in cooler than normal lows tonight and Monday night. 20 Mid level ridge axis will extend up Eastern Seaboard. while at the sfc a ridge will extend down the Appalachians into Ga as high pressure centers over New England.
540 PM EDT Sun Oct 9 2016 Canadian high pressure will build across the northern Mid- Atlantic tonight and Monday before shifting offshore during the middle of the week.
High pressure over the Great Lakes region will keep southern Wisconsin dry through Monday. Increasing southerly winds will usher warmer air into the area tomorrow.
143 PM EDT Sun Oct 9 2016 High pressure across the Great Lakes and Ohio Valley will provide another day of dry and cool weather. Highs today will rebound into the lower to middle 60s. Lows tonight will generally be in the lower to middle 40s.
High pressure will settle over the region this week providing cooler and dry weather. Dry high pressure continues to build into the area from the north under clear skies. This airmass will provide the CSRA and Midlands with the coolest temperatures since last spring with lows mainly in the 40s and highs in the lower to mid 70s.
340 PM CDT SUN OCT 9 2016 Ridge axis extends from near Springfield MO to St. Overnight lows will likely be a little warmer Monday morning than they were this morning due to the increasing southerly flow. Speaking of clouds, moisture aloft should be increasing steadily and the trof over Colorado will be moving into the Great Plains. The GFS and NAM throw a wave of vorticity out from this trof over us during the afternoon and both produce some isolated light rain showers.
335 PM EDT Sun Oct 9 2016 Low pressure forming near the Mid Atlantic coast will pull moisture north then track south and east of our region tonight.
Weak cold front was located along Highway 30 and was slowly sagging southward. 3 am temperatures ranged from the lower to mid 40s north of the front to the upper 40s to lower 50s to the south. Afternoon maximum temperatures will range from the lower to mid 60s north to the lower 70s south. This will be a warmer night with lows ranging from the mid 40s to the lower 50s.
658 PM EDT Sun Oct 9 2016 Post-tropical storm Matthew passes well south and east of the region tonight as high pressure builds east from the Great Lakes.
305 PM EDT SUN OCT 9 2016 Water vapor imagery shows upper ridging sliding into the area behind the exiting trough. Temperatures last night were solidly in the 30s, and expect to see temps near to slightly cooler than that tonight. With slightly cooler temperatures and better radiational cooling, we should see frost become more widespread. The upper ridge will amplify Monday into Monday night as it moves slowly east into New England. This will be in response to the upper trough dropping southwest out of western Canada. High pressure will remain in control tomorrow to provide a dry day, but temperatures will be slow to respond to warming aloft as inversion heights remain low and mixing is limited.
The higher terrain around Glacier, including Marias and Logan Passes, will receive up to a foot of new snow by Monday evening. While the lower elevations, West Glacier and Polebridge, should receive 2 to 5 inches of snow.
411 PM EDT Sun Oct 9 2016 Post-tropical storm Matthew passes well south and east of the region tonight as high pressure builds east from the Great Lakes.
Overall dry forecast with afternoon highs a few degrees warmer appears on track. Other than the high clouds expected today across mainly northeast OK. the weather should be mild this afternoon with temperatures a couple degrees warmer than yesterday. Low temperatures on Monday will be a few degrees warmer than today's cool start. Low pressure system will start to deepen in the northern plains on Monday.
Short wave ridging builds in behind the departing southern system this evening and should keep things dry from mid evening through early afternoon tomorrow.
312 PM CDT Sun Oct 9 2016 Latest water vapor imagery and surface map shows broad ridging across the northern high plains with strong low level warm advection continuing. A cold front currently in far southern Saskatchewan, bowing into north central Montana will continue to advance southeast tonight.
1108 AM MDT Sun Oct 9 2016 Upper level analysis has broad flat ridge over the western CONUS with trof across southwest Canada. At the surface, high pressure is located across Minnesota with low pressure across north central Montana. Temperatures at 3am across the CWA range from the 30s across central SD to the low 50s in Northeast WY. Dry weather will continue as upper ridge axis passes over the northern plains. Mid level flow will become southwesterly, and warmer air will advect into the region. Tight pressure gradient between exiting high in Minnesota and approaching low pressure in Montana will result in gusty southerly winds across central SD in the afternoon. Upper ridge will shift into the Great Lakes region as SW Canadian trof digs into the Northern Rockies.
953 AM MDT Thu Mar 16 2017 Weak low pressure trough and cold front will move across the region today with showers moving across the forecast area. At the upper levels, the upper level ridge will give way to more zonal flow, with the onset of a westerly jet streak. A cold front is currently pushing through central Montana, which is evident by the increasing prefrontal returns on the KBLX radar to the north and west. Friday will bring cooler temps as an upper level ridge begins to take hold of the Northern Rockies.
High pressure on the Gulf coast dominates with clear skies and northeasterly winds. A highly amplified upper level pattern continues over the CONUS with an upper low over eastern Quebec and deep troughing extending south over the eastern seaboard. The upper low moves northeast by Friday and will be located north of Newfoundland.
/issued 343 AM CDT Thu Mar 16 2017/ The high pressure that has hovered across the region has moved off to the east which will allow today high temperatures to be near the mid 60s south of I-20, and the lower 60s elsewhere. Friday, clouds cover will continue to increase from the west to east ahead of weak cold front off to our northwest, temperatures will be in the mid to lower 70s across most of the region, along with light southerly winds. Overnight minimum temperatures will be near the lower 60s to upper 50s so during the morning hours a jacket may be need.
Update: Updated the forecast to better time the precipitation band associated with a surface cold front pushing through eastern Montana this morning and early afternoon. Gilchrist Previous discussion: Cold front is over Central Montana at 08z with rain showers occurring ahead of the front. Better mixing will allow some areas north of the Missouri River to be a few degrees warmer than yesterday even though there will be cooler air aloft.
618 AM CDT Thu Mar 16 2017 Appears that large scale flow is becoming a bit more progressive thanks in part to deepening longwave trof digging off the Canadian west coast. Wv imagery this morning a well amplified ridge extending from the nrn Plain up thru cntrl Canada. Increasing thkns building in from the west will contribute relatively warmer high temps the next several days despite a dry cold front making a push southward into the CWA Thursday night.
1101 AM EDT Thu Mar 16 2017 Canadian high pressure will settle over the area tonight providing another very cold night with a hard freeze expected. Warming temperatures will begin Friday due to a developing southerly flow as the high moves into the Atlantic.
A cold frontal passage occurred overnight which will place the forecast area under a dry and cooler westerly flow through tonight. a cold front that swept across the region last night and early this morning has lowered snow levels and precipitation is diminishing behind the front.
937 AM EDT Thu Mar 16 2017 Low pressure will continue to pull away to the northeast today through tonight. High pressure will build in from the west on Friday and will crest over the region Friday night.
702 AM EDT Thu Mar 16 2017 VFR conditions expected throughout the TAF period with high pressure in control. Mid and high level clouds start to move in from the west overnight as the high slides east and the next weather system approaches.
631 AM CDT Thu Mar 16 2017 The H85 thermal ridge is progged to expand eastward as a mid/upper ridge over the Rockies dampens and emerges over the Plains. rising heights/increasing thickness are progged as another mid/upper ridge translates eastward across the Rockies and over the Plains.
738 AM EDT Thu Mar 16 2017 Aviation High pressure will slide through the region today bringing fair weather and sunny skies. The quiet weather will continue into tonight as the high slips away to the southeast. The light snow will mix with a bit of freezing rain Friday morning as warmer air aloft rides over some residual cold air at the surface.
High pressure remains stationed over the Deep South.
The rest of the forecast still appears to be on track with a few areas experiencing a bit of light drizzle with strong southerly winds and warmer conditions. These winds are expected to transport warmer temperatures and also increasing low level moisture back into the region. combined with increasing warm air advection interacting with the higher terrain locations of Southeast Oklahoma could create some patchy areas of light drizzle during the day today.
1132 AM EDT Thu Mar 16 2017 High amplitude long wave trough across the eastern US is slowly pulling away from the local area to the northeast. but the RH values will combine with fuel moistures below 10 percent to warrant the high fire danger. Winds also calming down as the ridge settles over the area. Low-level flow starts turning more west to southwest overnight tonight should keep most areas outside of the higher elevations at or a bit above freezing with highs climbing back up to around normal for Friday. As the associated cold front moves across the CWA, the moisture will diminish as will the showers.
High pressure centered on the Gulf coast this morning will dominate with a cool dry northeasterly to northerly low level flow. High pressure on the Gulf coast dominates with clear skies and northeasterly to northerly winds. High pressure dominates today with northeast to north winds at 15 knots or less.
Solar heating will help warm temperatures above freezing by 15z, so will let the current Freeze Warning expire then.

Drier air moving in this morning as weak ridging builds overhead. Have updated the forecast to match these trends, mostly across southeast Oregon and the lower Snake Plain this morning.
Today will be sunny and cool with lighter winds as high pressure center builds over the area.
1034 AM EDT Thu Mar 16 2017 High pressure builds across the southeastern states this afternoon.
549 AM MDT Thu Mar 16 2017 Dry and benign weather expected to continue late this week as a low amplitude ridge axis moves eastward into the Great Plains today. Models do show a weak cold front moving into Wyoming this afternoon. It will be noticeably more windy today ahead of the cold front. Friday will be slightly cooler across most of the area as the cold front moves southeast.
/issued 357 AM CDT Thu Mar 16 2017/ WNWRLY flow continues today across the region as an upper level ridge crosses the CWFA. A cold front is expected to approach the area Friday around sunrise. Cold front pushes south through our area early Friday. Reenforcement for the marginally cooler air mass doesn't arrive until later in the day as surface pressure falls deepen to our west and weak instability aloft works around the ridge shifting east.
710 AM CDT Thu Mar 16 2017 Ridge of high pressure currently over central Illinois will shift eastward into the Ohio River Valley today, allowing southerly flow to develop across the region. High temperatures will climb into the lower to middle 40s. Cold front will push through central and southeast Illinois on Friday, accompanied by scattered showers and perhaps a few thunderstorms. High temperatures will climb well into the 50s, with readings reaching the lower 60s across the S/SW. Once the front passes, any lingering showers will come to an end south of I-70 by Friday evening, followed by cooler/drier weather across the board through the upcoming weekend.
730 AM EDT Thu Mar 16 2017 Arctic high pressure will extend across central NC through tonight then drift east on Friday.
932 AM EDT Thu Mar 16 2017 High pressure will gradually build east from the mid-Mississippi valley through early Friday.
606 AM CDT Thu Mar 16 2017 An upper level ridge will build across the central CONUS for today, and in a warm air advection regime temperatures will respond with highs closing in on 70 over far south central SD, and upper to mid 50s through the MO River corridor. Back to the north and east where snow cover resides, temperature recovery will be hampered with highs remaining in the lower to mid 40s. Trough swings through the region on Friday, with the surface pressure gradient tightening across the northern Plains. Main impact will be gusty northwest winds and slightly cooler temperatures. Highs will be in the lower 40s to mid 50s, again warmest in the Missouri Valley.
806 AM EDT Thu Mar 16 2017 Cold and dry high pressure will move overhead, with a hard freeze again likely from tonight into Friday morning.

The hot and dry pattern has continued today with an upper ridge over Alabama and residual dry air through much of the atmosphere.
cold front near an International Falls to Fargo line moving southeast.
651 PM CDT FRI SEP 9 2016 Focus is on the progression of the cold frontal boundary today and the associated convection. The surface cold frontal boundary was located from KSUX to KGRI to KGCK at 18Z this afternoon with pressure rises of 1 to 3mb behind the boundary and with post frontal wind gusts of 30 to 35 mph.
841 PM EDT FRI SEP 9 2016 A stalled front will linger over Pennsylvania through the night, then lift north of the region as a warm front early Saturday.
913 PM EDT Fri Sep 9 2016 Warm and humid conditions will continue until a strong cold front crosses the area Saturday night. Much of Saturday looks to be rain free, but an approaching cold front will spawn showers and thunderstorms by late afternoon. The upper trough and associated surface cold front will cross the region Saturday night, with much of the area in a slight risk for severe thunderstorms especially in the evening.
Upper ridge over the area tonight with frontal boundary draped down through southern Illinois into central Missouri at this time.
