Cold front approaching from the west will bring showers and scattered thunderstorms today. The passing cold front will lead to a tight gradient in high temperatures north to south today, but highs will generally be above-average. Scattered showers will linger across the far south this evening as the front moves into the Mid-Atlantic region and the upper level trough swings into Eastern Pennsylvania.
Early this morning, high pressure centered to the southeast of the area remained in control with only some high clouds drifting by from time to time in most locations. Meanwhile southerly to southwest winds are observed on the ridgetops and in some of the more open areas. Temperatures are mild for late October with upper 40s to lower 50s currently observed in these valley locations with low to mid 60s on the ridges. At the same town, the cold front becoming increasingly sheared will drop into the Ohio Valley region later today and into the region tonight.
634 AM CDT Sun Oct 30 2016 A cold front will exit southeast KS early this morning leaving widespread stratus in it's wake. Low clouds are expected to mix out toward mid day but an airmass change will keep temperatures closer to climate normals with highs ranging from the mid and upper 60s across portions of central KS to the lower 70s near the OK state line. Light east-northeast winds will return to the south becoming breezy across central KS late tonight as low pressure deepens over the Northern High Plains.

This trough will move east this evening and overnight tonight causing the winds to veer to the south-southwest at about 10 kts. Passage of cold front last night has produced light northerly winds for the Texas and Oklahoma Panhandles. Have chosen to hold temperatures on the lower side but certainty of outcome is on the low side.

Stratus gradually burning off this afternoon, with a much cooler airmass across SW KS. Drier conditions are likely to linger into the early part of the work week as medium range models indicate weak upper level ridging in the Central Plains shifting further east toward the eastern seaboard while moisture is slow to return to western Kansas limiting instability.
1031 AM EDT Sun Oct 30 2016 Aviation section updated A cold front across extreme northern Indiana to northern Missouri will push south across Indiana today and will stall near the Tennessee Kentucky border tonight as high pressure moves into the great lakes. The high pressure system will move on to the east Monday night and low pressure moving into the upper midwest will pull a warm front north across our region.
Ongoing drizzle across southern WI due to shallow saturated air warmer than -8C (the snow growth zone), and weak lift as low pressure tracks through northern IL and southern MI. Temperatures are hovering just below freezing across much of south central WI this afternoon. Expect temps to drop below freezing in portions of southeast WI through late afternoon as the sun goes down. Light ice accumulations due to freezing drizzle on untreated roads could cause slippery driving conditions during the afternoon commute. It should take a little longer for far southeast WI to drop below freezing, so we should have a shorter time period of freezing drizzle than inland areas.
150 PM MST Fri Feb 24 2017 Upper low has moved over western IA, and weak ridging has developed over then northern Rockies. Another upper low is moving into the Pacific Northwest.
Upper trough still spinning over northeast Nebraska early this morning, and this will continue to provide lift for continued snow across southeast portions of the area, primarily south of a Tyndall-southern Sioux Falls-Windom line this morning. Cool northwest flow will keep temperatures mainly below freezing on Saturday.
10 inches across Western Nebraska and 1025 high pressure will build across the same area.
Upper low dominates the weather picture across our region with an associated deformation zone extending from Idaho across southern Montana and Wyoming. A secondary trof axis moves across our region Saturday leading to increasing areal coverage of light snow again. However, accumulations at the lower elevations will be limited by a brisk westerly downslope Saturday. Look for precipitation to diminish Saturday night as that upper trof axis slides southeast of the region. we do not expect much additional snowfall (around an inch at best for most of these locations), but believe its prudent to hang on to the highlights through the morning commute.
This combined with 30-40 kts of flow at H7-H8 will yield windy conditions at Arlington and even Bordeaux as a weak lee trough moves onto the plains. Wind speeds may increase across the high plains on Saturday afternoon as the trough pushes eastward. Regarding temperatures, remaining cold through the weekend w/ deep snow pack and large scale troughing.
Winds are expected to eventually become gusty out of the northwest to west at all terminals this afternoon although timing is uncertain at MAF and INK due to a cold front impacting the area. /issued 407 AM CST Fri Feb 24 2017/ Upper low over the Central Plains this morning with a broad trough extending to Mexico will move east today.

347 PM CST Fri Feb 24 2017 Satellite and upper air data showing the main low/trough axis which brought accumulating snowfall to the CWA continuing to slide east across the Plains this afternoon. At the surface, as expected, gusty north-northwest winds have been in place behind the cold front, with CAA and a tightened pressure gradient.
The low pressure system which resulted in significant snowfall across the Magic Valley and areas south has moved further northeast. A few showers cannot be completely ruled out over through Saturday night as an area of low pressure moves southwest near the Pacific coastline. The next influencing system will send an Alaskan low pressure system down the Pacific coast, with moisture just beginning to reach into the northern extremes of the forecast area late Saturday night.
This period will be controlled by an upper trough over the area with disturbances dropping into the area. Abundant moisture under the trough will continue to contribute to light snow showers or flurries through Saturday.

Tonight, conditions should remain fairly quiet under northwesterly flow aloft and weak high pressure moving east.
328 PM CST Fri Feb 24 2017 The cold front is through the area at this time and into eastern Illinois. It will feel pretty cold though since we haven't seen lows in the 20s to low 30s in more than a week! Clouds will clear out on Saturday with high pressure building overhead. Seasonal temperatures will continue with highs in the low to mid 40s along and south of the I-70 corridor cooling to the mid and upper 30s further north.
1215 PM CST Fri Feb 24 2017 MVFR CIGS impacting only a few terminals early this afternoon, but it is quickly getting scattered out courtesy of the impingement of a cold front.

Cold front positioned over the Texas Hill Country this afternoon will move into the area by mid evening (will make progress by early evening), with increasing north to northeast winds as the pressure rises and pressure gradient increases. Thus, a cooler night tonight and especially cooler on Saturday. Most guidance for highs is cooler than previous forecast, so went with it.

342 PM CST Fri Feb 24 2017 A vigorous storm system currently moving across the upper Midwest and into the Great Lakes region will push a cold front across the forecast area tonight. In the wake of the cold front, high pressure shifting east across the region will result in dry and cooler weather through the weekend with temperatures averaging closer to normal, even somewhat below average for lows Saturday night.
Isolated to widely scattered showers and thunderstorms will begin to develop along the cold front this afternoon, especially across south central Illinois.
The redevelopment of these snow showers are reflected well in the mid-morning runs of the higher resolution models, however, coverage is expected to be generally spotty in nature.
Will extend winter highlights through this afternoon with continued impacts to travel expected over the higher passes and expand highlights into the northwest San Juans where WNW component and ongoing showers will drop a few more inches of snow by this afternoon. Amplified ridging over both oceans is leaving a positively tilted long wave trough axis from the arctic to the Desert SW. There are numerous shorter wave troughs embedded in the westerlies from the Central Plains westward across the intermountain west to off the left coast of Oregon. Another vigorous upper level trough will move down the West Coast late Friday into Saturday.
