Winds will continue to diminish through early evening as high pressure builds in.
VFR conditions and light southeast winds will shift from the northwest and increase Monday after 12Z as a cold front moves through the area. There isn't a good push of cooler air with this front, thus temperatures this afternoon are on target to top out similarly to yesterday, with highs in the 60s for most of the region. Resulting temperatures on Monday afternoon will be a few degrees cooler than today, particularly along and north of I-10.
758 PM EST Sun Jan 5 2020 Snow showers with a crossing disturbance will accumulate light snow mainly in the ridges and north of Interstate 80 tonight.
A cold front pushed across the southern Great Basin this morning and brought breezy winds with gusts in the 25-35 MPH range. From surface observations, the front has just reached the Morongo Basin and the lower Colorado River valley.
Light south to southwest winds may become more west/northwesterly overnight for SAT, AUS, and SSF as a pre-frontal trough approaches Interstate 35.
) A cold front entering Texas (in response to an upper system approaching the Great Lakes) is expected to stall/meander, then move SWD and eventually across the CWA Monday night, as the current west system moves east across the Plains (deterministic output.
952 PM EST Sun Jan 5 2020 A dry cold front will sweep across the area this evening. High pressure will briefly build in on Monday.
635 PM EST Sun Jan 5 2020 Weak low pressure moving by to the north of the state tonight will likely bring a several hour period of light snow or flurries tonight into early Monday across the region, mainly north of Route 22.
Upper flow will become increasingly zonal with high pressure dominating at the surface overnight.
The fog has lifted throughout the central valley and has left us with a stratus deck that will hamper max temperatures this afternoon, so expect highs to be at least 10 degrees cooler than yesterday in some areas.
932 PM EST Sun Jan 5 2020 Weak high pressure will prevail across the area tonight through Monday.
However, a cold front nearing the area from the north will bring IFR/MVFR ceilings to GLH, GWO and GTR after 06/14Z.

702 PM EST Sun Jan 5 2020 High pressure will build across the area tonight through Monday.
Clear skies will allow for strong radiative cooling to take place as temps drop quickly into the low 40s across central Florida after midnight. However, widespread frost formation looks limited due to: 1) the high pressure center being centered to our west (as opposed to overhead); 2) the 915MHz wind profiler at the Cape shows winds at 925mb are still at 5-10 knots, which will limit decoupling of the lower atmosphere.
/issued 254 PM CST Sun Jan 5 2020/ (Tonight and Monday) Weak cold front has sagged into the area this afternoon, bringing slightly cooler temperatures and north winds. Temperatures have climbed into the lower 70s south of the front across I-10 locations, with low/mid 60s for areas along I-20.
528 PM CST Sun Jan 5 2020 A dry cold front continues to move through the region this afternoon. Mon is expected to be cooler compared to today with SE winds and clouds spreading across much of the area. This cooler trend is expected to continue into Mon night. Have generally trended toward the cooler MOS guidance for Mon and into Mon night which is in good agreement with the GEFS/SREF/ECMWF ensemble data. Wind will then turn back to the south-southeast Monday afternoon as high pressure drifts east of the Mississippi Valley.
Clear skies remain through the evening as high pressure to our south continues to dominate our weather. Ideal radiational cooling again tonight with overnight lows forecasted to be in the mid 30s, a few degrees warmer than last night thanks to a more westerly flow aloft.

A dry cold front will bring cooler weather Monday.
350 PM CST Sun Jan 5 2020 Mid-afternoon sfc analysis shows high pressure now centered over Mississippi Sound and ridging wswwd, allowing a light onshore low-level flow to prevail over the forecast area. Meanwhile, our next cold front is noted to our n/nw, extending from low pressure over the wrn Great Lakes through the Missouri Valley to the Red River Region and cntl TX. Water vapor imagery shows flat ridging aloft centered just to our west with a series of disturbances noted upstream over the wrn CONUS. With the return flow in place, warmer temps are on tap with lows tonight about 10 degrees warmer than this morning's lows. Highs tomorrow will remain rather abnormally warm with readings generally in the lower 70s.

935 PM EST Sun Jan 5 2020 High pressure will build across the middle Atlantic through Monday night.
528 PM CST Sun Jan 5 2020 At 2 PM, a cold front extended from Iron Mountain Michigan to Dubuque, IA. The highest wind gust so far is 48 mph near Dexter, MN at 1205 PM. A ridge of high pressure will build across the area late tonight and then move quickly east of the area on Monday.
System will bring some light snow to the central mountains from this evening into mid-morning Monday, with light (1-3 inch) accumulations across the higher peaks of the Sawatch and Mosquito ranges. After a lull this evening, northwest winds will increase after midnight over the higher terrain, and with fairly healthy mountain wave developing, could see some gusts approach 50 kts over favored lee slopes, including the Rampart Range near the Air Force Academy.
The bulk of the snow is expected over the north and ridges. Low pressure will bring a quick hit of snow south and east of Pittsburgh on Tuesday.
Gusty winds this morning will weaken as high pressure takes over the lower Missouri valley. Sunny and a little warmer temperatures are expected on Tuesday with weak downslope surface winds.
This is maintaining the infusion of cool post cold frontal air. Temperatures along the island chain range from the lower to upper 60s with dew points in the lower 50s. Temperatures are expected to bottom out broadly near 60 degrees, a bit cooler in the Upper Keys.
321 AM EST Mon Jan 6 2020 An upper level high pressure aloft will continue to build over the area through Tuesday.
1022 PM MST Sun Jan 5 2020 Current surface map places weak high pressure across the central plains. Upper level ridge builds across the area Tuesday. Deep upper trof moves into the plains for the last half of the week, with southward surge of arctic air.
114 AM EST Mon Jan 6 2020 Expecting VFR trough the period.
High pressure sits over the region as last nights front pushes eastward, and winds have finally died down aside for some lingering gusts in our northeast SD and western MN counties.
High pressure in place across the plains will quickly push across the Ohio Valley today. A quick moving but weak area of low pressure will sweep through across Tennessee.
Temperatures should remain warm enough for all liquid precipitation with this system, although I can't rule some brief mixed precipitation at the highest elevations at the onset and the exit of the precipitation.
A cold front will be approaching the area, and some mid-level clouds will begin to move over the terminals during the afternoon and evening hours. At KMSY, lower ceilings of 2000 to 3000 feet could develop after 06z tomorrow as the cold front pushes across the terminal.
101 AM EST Mon Jan 6 2020 Dry high pressure will dominate through Monday. A cold front with limited moisture will cross the area Tuesday. The region will be under dry zonal flow Monday with continued surface ridging.
Northwest and north flow will increase behind a cold front late tonight into Monday with strong wind gusts likely along/east of the central mountain chain to the eastern highlands. A cold front will cross the state tonight which will cause high temperatures on Monday to fall to slightly below normal for areas west of the central mountain chain.
A weak cold front will move through the terminals during the mid to late morning tomorrow as a result winds will shift to the north and increase. Cold front cleared the area this morning which has kept temperatures a few degrees colder than yesterday with some northerly winds. Monday night with clear skies, weakening winds, and a cooler airmass in place temperatures will be able to drop into the low to mid 20's area wide (which is where we should be for this time of year).
High pressure over the Nrn FL Peninsula will shift eastward through tonight. After a frosty start this morning with temperatures in the low 30s, we'll warm up to the mid 60s under mostly clear skies. Tonight will be warmer, with lows in the low- mid 40s.
The second and weaker of today's two short wave troughs passed through southwestern Idaho around sunset. The next pcpn should come in Monday morning with a weak warm front and farther north than today's pcpn. On Monday a slow-moving warm front will lift north keeping a chance of showers in the mountains of e-central Oregon and w-central Idaho.
Overnight temperatures should drop into the low to mid 30s under clear skies. Temperatures overperformed this afternoon, as moderate southwest winds advected in a warmer mixed airmass.
227 AM EST Mon Jan 6 2020 Dry high pressure will be in control today. A cold front with limited moisture will cross the area Tuesday. The region will be under dry zonal flow aloft today with continued surface ridging. Most of the moisture and energy associated with this disturbance is forecast to remain north of the area, and low-level moisture will remain limited with h85 westerly flow following the quick passage of a weak cold front. The highest chances will be in the north closer to greater upper lift and moisture. Temperatures will then drop to near freezing Tuesday night with diminishing winds and clearing skies.
A dry cold front will make its way into the CLL area by early Mon evening and off the coast around midnight. The regional atmosphere will be too dry to support any precipitation in association with the passage of a tomorrow evening/early Tuesday morning cold front.
232 AM CST Mon Jan 6 2020 High pressure was centered near St. Still expect the forecast to remain dry as atmosphere over the area is very dry, so the trough will not bring much more than mostly cloudy skies this afternoon and tonight.
High pressure remains just south of the cntrl TN Valley this Sun evening across the cntrl Gulf region, with a broad WNW flow pattern in place across much of the SE states.
1056 PM EST Sun Jan 5 2020 Weak low pressure moving by to the north of the state tonight will likely bring a several hour period of light snow or flurries tonight into early Monday across the region, mainly north of Route 22. Another weak low moving east from the Lower Ohio Valley to the Delmarva Coast Tuesday into Tuesday evening will likely bring a light snowfall to much of the region during this period.
The next short wave trough expected to move through the westerly flow aloft and across the forecast area will move east of the Rockies this evening with a secondary short wave trough phasing into the main trough as it moves across the central High Plains region during the day on Monday. Northwest flow aloft will follow on Tuesday with the apex of the upper ridge over the western U.
A cold front pushed across the southern Great Basin this morning and brought breezy winds with gusts in the 25-35 MPH range. From surface observations, the front has just reached the Morongo Basin and the lower Colorado River valley. Ridging will be short-lived as the upstream trough speeds into the Great Basin Tuesday night.
Otherwise, the highs we had going for today still look on track with values mainly in the lower 50s.
High pressure will continue to dominate the weather pattern through tonight and into tomorrow morning, with clear skies, cool temperatures, and dry conditions. Overnight low temperatures tonight are expected to drop down into the mid to lower 30s tonight, potentially reaching as low as freezing in some areas, as radiational cooling and light winds make conditions ideal for widespread frost development late tonight and into tomorrow morning throughout inland areas. Cold temperatures and high pressure will continue on into Monday, with lingering inland frost clearing out in the morning hours after sunrise. The influence of high pressure over the area will begin to recede late Monday and Tuesday as a mostly dry cold front moves into the region, with cold dry air once again settling in over the southeastern US in the afternoon and evening on Tuesday.
/Issued 932 PM EST Sun Jan 5 2020/ High pressure continues across the CWA this evening.
High pressure ridging will continue over the area tonight into Monday, with mainly clear skies overnight and lows in the low/mid 40s. A short wave will approach the area Monday afternoon with a weak low/cold front moving into the delta. High temperatures will range from the low 60s in the north to the low 70s in the south. This will quickly move east and high pressure will build in at the surface.
as a weak upper level trof axis moves through the region.
1030 PM MST Sun Jan 5 2020 Short term forecast period will cover timeframe for the High Wind Warnings that will go in effect later this evening across the gap wind areas in addition to central Laramie County.
112 AM EST Mon Jan 6 2020 Weak low pressure moving by to the north of the state tonight will likely bring a several hour period of light snow or flurries tonight into early Monday across the region, mainly north of Route 22. Another weak low moving east from the Lower Ohio Valley to the Delmarva Coast Tuesday into Tuesday evening will likely bring a light snowfall to much of the region during this period.
The best focus for the snowfall will be overnight with intensity decreasing on Monday with low-density snowfall expected as slightly cooler temperatures moves across the region. Mountain snow showers should diminish by Tuesday morning with zonal flow returning as a weak, transitory ridge crosses the region. Meanwhile, the next Pacific NW trough moving ashore will help push the ridge of high pressure quickly east of the Rockies by Tuesday night.
Low pressure will bring a quick hit of snow south and east of Pittsburgh on Tuesday.
1216 AM EST Mon Jan 6 2020 [Through 06Z Tuesday] VFR for the night 24 hours with light winds as high pressure dominates the southeast US. Upper flow will become increasingly zonal with high pressure dominating at the surface overnight.
1053 PM CST Sun Jan 5 2020 At 2 PM, a cold front extended from Iron Mountain Michigan to Dubuque, IA. The highest wind gust so far is 48 mph near Dexter, MN at 1205 PM. A ridge of high pressure will build across the area late tonight and then move quickly east of the area on Monday.
High pressure will build in Tuesday night and lead to widespread temperatures below zero, but winds will be light so wind chills will not be much colder than the air temperature. Expecting some high clouds with warm temperatures as afternoon highs will reach the low 30s at most locations. A cold front will move through on Tuesday, and high pressure will build in Tuesday night, so did go toward the colder end of guidance.
1054 PM CST Sun Jan 5 2020 A dry cold front continues to move through the region this afternoon. Mon is expected to be cooler compared to today with SE winds and clouds spreading across much of the area. This cooler trend is expected to continue into Mon night. Have generally trended toward the cooler MOS guidance for Mon and into Mon night which is in good agreement with the GEFS/SREF/ECMWF ensemble data. High pressure will slide into the region during the morning hours, with winds becoming light an variable. As the high shifts to our east tomorrow, winds will turn to the ESE before again becoming variable on Monday evening.
High pressure mid week. Stronger, wetter low pressure system late week. Drier air working in behind a cold front will yield decreasing clouds through the late morning hours with mainly clear skies this afternoon outside of a little jet cirrus across our northern counties. Have light snowfall accumulations coded at this point on Tuesday, with a change over to a rain snow mix or all rain across the lowlands as the day progresses, remaining snow across the higher terrain.
1221 AM EST Mon Jan 6 2020 A dry cold front will sweep across the area this evening. High pressure will briefly build in on Monday. A compact low pressure system will pass just southeast of the area on Tuesday. A cold front is pushing east across the area this evening. High pressure will build across the region through the day and head off to the east during the evening. An area of low pressure southeast of the region will bring a mix of snow and rain to southeastern portions of the forecast area on Tuesday.
1235 AM EST Mon Jan 6 2020 High pressure will extend across the region through Monday. A cold front will push offshore Tuesday with high pressure returning through the middle of the week. Early this evening: High pressure will continue to be the primary weather feature through the overnight.
1027 PM EST Sun Jan 5 2020 Weak low pressure moving by to the north of the state tonight will likely bring a several hour period of light snow or flurries tonight into early Monday across the region, mainly north of Route 22. Another weak low moving east from the Lower Ohio Valley to the Delmarva Coast Tuesday into Tuesday evening will likely bring a light snowfall to much of the region during this period.
For today, look for quiet weather ahead of the next cold front that will traverse the region tonight. Breezy northwest winds are expected for the higher elevations west of the Red River Valley with 20 to 25 mph sustained winds and occasional gusts to near 35 mph as the front passes through.
326 AM MST Mon Jan 6 2020 Overrunning snow event is expected to develop tonight with the merger of the lee trof with an arctic boundary over central Montana. By this evening the front will settle across central and southern Montana with Canadian high pressure nosing into the northern Plains. Upper ridge will be building over the west coast, with moisture streaming around the top of the ridge. Pattern is fairly progressive so as next trof approaches the west coast on Tuesday, the upper ridge will be pushed east into the northern Rockies. The snow band will begin to lift across northeast Montana by Tuesday afternoon, but with the amplifying ridge, the better dynamics shift north with highest snow amounts expected near the Canadian border into Tuesday night.
Highs today will be warmer - mid 60s to near 70 - south of the front, and then the low will kick the cold front through with temperatures falling into the 30s and 40s tonight behind it.
Following some fog early this morning over the eastern half of the region, few forecast challenges exist today underneath weak zonal flow and mild southerlies in the low levels. Highs tomorrow will only cool to near normal values for most areas as surface ridging expands south.
Tue-Wed night: With ridging aloft progged to build over the region from the west -- expect dry conditions and a warming trend, with highs in the 50s.
