Northwest winds will also pick up quite a bit later tonight and into Wednesday with the area between the departing low and a high pressure system building in across the northern Plains.
/Today through Wednesday/ Showers and isolated thunderstorms will continue today along a quasi-stationary warm front. A cold front will dive south across Oklahoma this afternoon, reaching the Red River by sunset. Dewpoints in the upper 60s to lower 70s ahead of the front will aid in destabalizing the lower atmosphere ahead of the front. Addtionally, an upper-trough across the midwest will further destabalize the mid to upper-levels allowing for the potential for late afternoon thunderstorms across the Interstate 30 corridor. Northwest flow in the wake of the departing upper-trough to drive convection south of the ArkLaTex tonight.
As it approaches, the low level jet has been increasing across south central and southeast Minnesota. Skies will gradually clear on Wednesday night as the 850 mb ridge axis gradually shifts east of the area.

Meanwhile, a dry cold front will drop southward through the plains in the wake of a northern stream upper trough moving through the northern plains towards the Upper Midwest and Great Lakes region on Tuesday. This front will bring a northerly wind shift overnight across the southeast plains, and usher in cooler conditions for Tuesday as winds shift around from an easterly upslope direction by afternoon.
High temperatures will be 10-15f degrees cooler than yesterday, with less wind and higher relative humidities. The airmass will remain dry however in the high mountain valleys with much lower relative humidity, but less wind will allow for slightly better conditions there as well. Upper level ridge will move across the Central Rockies Wednesday. Flow aloft turns southwest as the ridge slides off to the east and a trough moves over the western states.
High pressure building out west will slowly drift towards the region and slide overhead by Wednesday.
A deep, large and sprawling anticyclone over the Gulf of Mexico will expand over the Sunshine State during the next couple of days, before gradually being suppressed into our region and over the archipelago of Cuba.

Upper trough axis will push the front into NE OK later this morning/early afternoon, then through the remainder of the area later this afternoon.
Temperatures have remained above freezing at nearly all locations overnight with ptype of rain being reported at all observation sites experiencing precip. Continued cooler than average temperatures prevail today and Wednesday with highs today in the 40s and lows tonight ranging from the upper 20s to lower 30s, but will be dependent upon cloud cover.
113 AM CDT Tue Oct 15 2019 With breezy south winds and mostly sunny skies, temperatures have ended up quite a bit warmer than expected today. The next trough and associated cold front is pushing out of the northern Rockies and into the northern Great Plains. Temperatures will also be 15 to 20 degrees cooler than today, with highs expected to be in the 50s and low 60s. Winds will diminish quickly Tuesday evening as high pressure moves in from the north. Dry conditions and mild conditions are expected through the rest of the work week as high pressure shifts off to the east and midlevel riding builds overhead.
A cold front will sweep into the region, from the northwest, early Tuesday morning, with rain chances developing across the Ozarks into north central and eastern Missouri through sunrise into Tuesday Afternoon. Warm today, with highs in the 70s, ahead of an approaching cold front. This boundary is associated with a decent 500mb trough churning into the Dakotas through tonight. Some frost cannot be ruled out early in the morning, Wednesday, in far northwest Missouri, as temps will dip into the lower 30s, but temperatures should remain above freezing. After prolonged, slow evolving, ridging over the central U.
Clouds are expected to slowly thin by late afternoon and SW-W winds this morning to will be W-NW later today ahead a cold front that will move through HOB-MAF 22Z/Tue-00Z/Wed, respectively.

Cooler and blustery weather will follow for the latter half of the work week. A generally light wind early will turn to the south as the high pressure area shifts off the coast. A potent occlusion/cold front will be approaching the region, with the first showers likely reaching our western zones before sunrise Wednesday.
Widespread cloud cover and breezy northwest winds overnight have kept surface temperatures mostly above the freezing mark with rain being the precipitation type so far. There is some uncertainty whether the lowest levels will become cold enough to support a full transition to snow so a rain- snow mix was used in the weather grids given the potential for some transition.
Strong winds behind a cold front today, then warming temperatures to end the week, are the initial highlights of the forecast. Strong low pressure system was diving into the Northern Plains this morning, with a surge of colder air wrapping around the low into the Central Plains. Winds die down this evening as high pressure begins to build into the region. Sub-zero 850 temps and lighter winds will allow lows to drop toward or below freezing tonight. However warmer weather is in the offing as mid level heights begin to rise Wednesday with a return to southerly low level flow.
1018 AM EDT Tue Oct 15 2019 Dry, seasonable weather will continue until a cold front brings showers and breezy conditions to the region on Wednesday. Eastward moving high pressure will remain in control today. This will result in plenty of sunshine and warmer temperatures. As a cold front approaches from the west, breezy conditions are expected to evolve as a tight pressure gradient builds. An inflation in shower intensity looks likely, as dawn approaches, due to coupling between the lower and upper level jets. This interaction will keep the higher rainfall rates going as the front crosses the rest of the region. An area of showers, associated with the trough axis and a secondary front, will move down from the northwest early Wednesday evening.
