/Issued 352 AM EST Sun Nov 15 2020/ Main feature of the short term is an elongating cold front that will bring chance to likely pops of showers to the CWA into early afternoon, primarily in N GA. We start off with high pressure over the Northern Plains and ridging all the was south into the Mississippi Valley and into the local area.
Today Through Monday Night A strong upper trough continues to move through the Plains and Midwest this morning. Northwest flow aloft will continue through the short term and ridging will become more amplified over the Rockies Monday. High temperatures today will be cooler in the mid 50s to mid 60s and in the lower to mid 60s Monday.
507 AM CST Sun Nov 15 2020 (Today and tonight) A cold frontal passage earlier this morning will leave cooler temperatures across the region.
524 AM CST Sun Nov 15 2020 Strong northwest flow aloft on the back side of an upper trough will mix down to the surface and keep gusts on the strong side this morning, especially across the eastern forecast area. Leaned toward a model blend with warmer temps expected on Monday. By Monday evening, sfc winds will be subsiding as high pressure builds in from North Dakota. Meanwhile, northwest flow will characterize the upper-levels, as an upper-trough departs eastward.
A lengthy western Atlantic ridge axis extending from just offshore of the entire Eastern United States, and reaching across the Sunshine State today, will exit further into the Atlantic Ocean. This will be in response to a weakening cold front dropping down the Florida Peninsula before becoming diffuse on Monday.
West-northwest flow aloft will prevail early this week, in the wake of this mornign's exiting upper trof over the Ohio Valley and Great Lakes. With much cooler dewpoints and a surface pressure ridge parking over the Midsouth tonight, prime radiational cooling conditions may result in sub-freezing lows in the valleys of west TN and northeast MS - not uncommon for this time of year. The details differ, but it appears that sufficiently deep height falls will occur late next Sunday into early next Monday to drive a cold front into the Midsouth.
SHORT TERM (Now through Monday): The main action in the short term will be an approaching cold front that will move through the area and offshore today. The front will impact high temperatures today by keeping them down in the lower to mid 80s across the area. Weather tonight will be cooler, with low temperatures ranging from around 50 across the north to the mid 60s for the lower RGV under mostly clear to partly cloudy skies. The cooler trend will continue on Monday with high temps in the mid 70s to the lower 80s under mostly sunny to partly cloudy skies.
A weak cold front will push through the CWA with breezy/windy spots by afternoon.
226 AM PST Sun Nov 15 2020 Warmer and drier weather will develop over Southern California today and Monday thanks to weak offshore flow.
356 AM CST Sun Nov 15 2020 A line of showers has developed along the cold front and is moving through Lee and Bastrop Counties. A cold front stretches from the DFW area to the Big Bend region and is moving toward the southeast. Temperatures across our CWA range from the upper 50s to the lower 70s and dewpoints are about the same.
Early this morning as of 0830Z, the 500mb trough axis is pivoting northeast and should be out of KS in the next couple of hours.
Surface analysis this morning shows a robust mid-latitude cyclone centered over northwest Wisconsin that is continuing to eject northeastward. An occluded front extends southeast from the low center into central Michigan, then transitions into a cold front stretching southwest from southern Michigan through central Texas. In the wake of the ejecting trough, quiet weather and northwesterly flow settle in today through Monday as ridging builds up in the west.
Near the surface, high pressure is drifting southeast across the Texas Panhandle. Tonight the winds will decrease after sunset and based on clear skies and the forecast dew points in the teens the lows tonight will likely range from 25 to around 32 degrees.

Cold front blew through last evening and currently stretches from central TX into southeast MO. Models remain consistent with upper ridging from the Northern Intermountain/Great Basin on Mon and into the Rockies for Tue. This will allow lee troughing to strengthen Wed setting up strong south winds and elevated fire conditions Wed afternoon. Strong and gusty northwest winds will continue overnight, strongest before midnight, as a cold front continues slicing southeast through southeast Kansas.
Further warming will occur Sunday night into Monday as a warm front moves through the region. The warm front will be accompanied by precipitation, mainly through central Idaho and northwest Montana. Due to the rising snow levels, snow accumulations will mainly occur during this time frame in the higher terrain and over mountain passes.
Afternoon temperatures will be warmer today with highs in the 50s across northeast Colorado. The jet shifts well north of Colorado tonight as an upper level ridge starts to form across the western states.
Approaching cold front set to push into our northwest toward sunrise, then race rapidly east and out of the mid-state by early afternoon ahead of a trailing upper trough. SFC/LL high pressure takes hold while upper trough shifts to upper ridging around mid-week ahead of our next storm system. A strong cold front is marching across Middle Tennessee this morning.
355 AM CST Sun Nov 15 2020 (Issued 355 AM CST Sun Nov 15 2020) Today and Tonight: The cold front is on track to slide across southern WI this morning. This is likely in association with an enhanced area of low level frontogenesis as well as the core of the upper level trough. Surface temperatures should still be above freezing, so no significant accumulation is expected, but given the strength of the winds, we could see some meaningful visibility restrictions within the pockets of heavier precip. Winds will gradually diminish tonight as the low pressure system exits the region.
The flurries or light snow will continue this morning, mainly along and north of the highway 2 corridor. More likely will see criteria remain just below advisory levels, but no doubt it will be windy and cooler today.
A dry cold front will push through the area later today into tonight with winds shifting to a northwesterly direction behind the front. A mostly dry cold front will move through the area today with meager return flow from the Gulf and weak lift. After some patchy fog this morning, some breaks in the cloud cover today are expected to allow high temperatures to reach the low to mid 80s across most of the area. For tonight, cooler and drier air will begin to move into the area behind the front.
424 AM EST Sun Nov 15 2020 Rain showers and high winds will accompany a crossing cold front today.

Dry northwesterly upper level flow will continue through first part of work week, with ridging influences building across mid state by mid portion of work week. A strong cold front is pushing east of the Mid State, trailed by gusty WNW winds.
The backdoor side of the Low pressure system, and the associated trof is beginning to exit the Midwest.
Some cooling is possible during the late portion of the week as an area of low pressure aloft starts to approach from the west. A rather benign weather pattern has taken hold across the west amidst quasi-zonal flow aloft, as a significant upper trough affects the Great Lakes region. Temperatures are currently running 2-6 degrees above yesterday's readings, and should top out in the low 80s this afternoon. An expansive cold front has moved into the southern High Plains and will stall east of the Rockies and Sangre de Cristos in New Mexico. However, high pressure over the Rockies will continue to favor weak surface pressure gradients and light easterly winds this evening through Monday. The early part of the workweek will see gradual building of mid- level heights in response to ridging building across the Southwest.
(This evening through Monday) In the wake of the cold frontal passage last night, a much cooler and drier airmass is over our area today. An upper level ridge will build into the southwestern US and move westward through Texas into the midweek.
Isolated showers have developed this afternoon over the area ahead of an approaching cold front. The cold front will push across the area tonight bringing in a cooler and drier airmass.
154 PM MST Sun Nov 15 2020 Lee-side troughing over the plains today has kept tight pressure gradient along the foothills. High pressure ridging begins to build into the region Monday resulting in much lighter winds for the foothills and plains along with a warming trend.
