205 AM EST Sat Nov 16 2019 Low pressure will move slowly northeastward near the coast through Saturday bringing rain to the area. Drying is forecast Sunday as the low moves farther northeast of the area. Low pressure will move northeastward slowly and deepen off the coast of the Carolinas through tonight. The upper low will be pushing off the FL/GA coast Saturday morning. Low pressure will continue to deepen on Saturday with a tight pressure gradient over the region. The deepest moisture will be shifting eastward by Saturday night as the low lifts toward the northeast. A mid/upper trough will be moving over the Mississippi Valley region on Sunday while a ridge in between the troughs moves over the Southeastern CONUS. Highs on Sunday will be warmer than Saturday, in the 50s.
/issued 840 PM CST Fri Nov 15 2019/ With sfc ridging directly ovhd, winds are calm across the entire Four State Region and with clear skies overnight, will see ample radiational cooling conditions. Only made minor overnight low temperature changes, mostly across our northern and eastern zones which typically see cooler min temps given these kinds of conditions. Removed much of the freezing fog for much of the region but did leave patchy fog across our southern third with some indications that we could see lower vsbys across the Lower Toledo Bend and Sam Rayburn County of Deep East Texas into West Central Louisiana.
Surface analysis this evening places a 1028 mb ridge of high pressure over the Lower Mississippi Valley and Southern Plains. /issued 253 PM CST Fri Nov 15 2019/ High pressure will remain over the Mid-South through much of the weekend. An upper trof and associated cold front will move into the region late Sunday afternoon into Sunday Night.
Upper low is currently centered over southern Alabama moving east. Surface and upper ridge situated to our west will dominate the weather across Middle Tennessee for at least the next 24 hrs.
Cooler air is settling in and winds have shifted to the NNW across the area. With high pressure settling in and drier air advecting across the peninsula, skies will begin to clear by late afternoon and the remainder of the weekend should be nice. With the cold front now well to the south and high pressure settling in, winds remain strong and gusty.
Over the next day, we'll continue to see dry conditions and warmer temperatures.
1122 PM EST Fri Nov 15 2019 A moisture-starved cold front will drop southeast across state the overnight. Another area of high pressure will move north of Lake Ontario Saturday. The clock-wise flow around this high will feed cold air into Pennsylvania on a brisk northeast wind. A weak cold front progressing southward into the Central Mountains at this hour. High pressure will build north of the region Saturday, making for a bright but chilly day in most areas with a brisk NE breeze.
Temperatures will be a little cooler on Saturday, but still 5 to 10 degrees above normal.
Sheltered spots could be a couple of degrees cooler. Sunday will be more of the same and a degree or two warmer.
Pattern change still on track around mid week with some breezy winds, cooler temperatures and maybe some rain/snow in southern Sierra Nevada and northern San Joaquin valley. The Evening Update: Temps and dewpoints running cooler than yesterday with clear skies, and diminishing winds. JHM The weather system exiting northern California this evening will allow more clearing and warming as the upper ridge builds back into northern California.
1152 PM CST Fri Nov 15 2019 Tonight-Saturday: Winds will likely remain up a bit overnight, which will lead to slightly warmer minimums. However recent trends and dry airmass still suggest a lean towards the warmer guidance.
Behind the cold front, Sunday will be 5 to 10 degrees cooler than today, but the highs in the 50s are still a few degrees above normal.
The trough and front will push the ridge south as it drops down the Front Range Saturday. Northwest and west-central CO and northeast UT should see a few degrees of cooling Sunday from the trailing edge of the cold front.
Another cold night is in store for tonight as lows will drop into the low to mid 30s. However, most areas should remain above freezing. Expect light winds and high temperatures in the low to mid 60s for tomorrow afternoon.
At the lower elevations fog and low clouds will develop.
Current upper level pattern is fairly zonal through the central plains with an upper level ridge moving through the southern plains. A trough is in the process of developing in the northern Rockies which will move into the area by later tonight. Tonight the upper level trough moves into western Kansas bringing a cold front. As the front moves through north winds will pick up 15-30 mph with post frontal stratus and the possibility of a few sprinkles of rain but not much in the way of organized precipitation due to the fact the lower levels will be moisture starved. Lows will range from the low 30s in the west to the upper 30s in the east.
Latest surface analysis shows a high center in East Texas with ridging across most of the state. As this ridge continues to shift east, southerly winds return bring todays high temperatures up a few degrees and slightly increasing dewpoints. Sunday, an upper trough drags a weak front across the region, but limited moisture will keep this FROPA dry, only leaving behind a wind shift and some slightly drier air.
trailing a cold front south through the Bahamas to Cuba. Deep layer ridging slides east along the Gulf coast and reaches the southeast quarter of the nation by late Sun. These clouds begin to clear and lift during the late morning and afternoon as drier and cooler air moves in with the ridging and will be in control overnight and Sun.
Upper level ridging is currently in place across the area which will lead to gradual warming and quiet conditions for the first half of the weekend. Upper level trough and attendant cold front will move into the region Sunday morning which will lower temperatures a bit and lead to gusty northerly winds behind the front.
Tonight Through Sunday An upper ridge is over the Rockies and Plains this afternoon with an upper low over the southeast corner of the U. Very dry air is noted over Arkansas on the back side of the upper low. These systems will move east Saturday and another upper low will move into the southwest U. An upper trough will move through the Plains Saturday night and Sunday along with a cold front, with little moisture to work with.
330 AM EST Sat Nov 16 2019 High pressure will bring a cold but dry weekend.
1008 PM EST Fri Nov 15 2019 Low pressure will move slowly northeastward near the coast through Saturday bringing rain to the area. Drying is forecast Sunday as the low moves farther northeast of the area. Low pressure will move northeastward slowly and deepen off the coast of the Carolinas through tonight. The upper low will be pushing off the FL/GA coast Saturday morning. Low pressure will continue to deepen on Saturday with a tight pressure gradient over the region. The deepest moisture will be shifting eastward by Saturday night as the low lifts toward the northeast. A mid/upper trough will be moving over the Mississippi Valley region on Sunday while a ridge in between the troughs moves over the Southeastern CONUS. Highs on Sunday will be warmer than Saturday, in the 50s.
210 AM EST Sat Nov 16 2019 Weak cold front washes out today with high pressure building in. Warmer mid week then unsettled toward the end of the work week. A weak cold front approaching from the north will yield increasing low level cloudiness across northern and western portions of the forecast area this morning before mixing out late this morning. Otherwise, just some mid and high clouds across extreme eastern portions of the area and some breezier easterly winds this afternoon along the highest ridges as an upper low makes its northerly turn up the coast off the Carolinas. Will see another cold night tonight with lows mostly in the lower to mid 20s as high pressure settles in with mostly clear skies.
Also added a slight chance for showers across the Panhandle into far southwest Nebraska where a few light showers aided by steep mid- level lapse rates may survive as they move southeast off the higher terrain to the west. Winds will increase as a Pacific cold front crosses the area. The front will promote deep mixing, so despite cloud cover, warmer air aloft will mix to the surface as the front passes, and will help highs reach the mid 60s across southwest Nebraska.
Associated weak cold front will move through Sunday along with a narrow band of forcing that may produce a few sprinkles or very light rain showers, with odds of measurable precip looking below mentionable levels at this time.
This morning will be off to a warmer start as diurnal cooling has been slow to non- existent overnight with stratus and sfc winds high enough just to keep low levels mixed. Drier air will filter back into the region on Saturday as high pressure builds to the north.
Today Through Sunday Night High pressure was over the region early this morning, which has allowed for no clouds, light winds and good radiational cooling. Localized areas of freezing fog have formed, primarily in outlying areas and near bodies of water.
Upper level ridging will build across the region today, with clearing expected this afternoon. Temperatures will be slightly cooler than yesterday.
As of this writing, a closed upper low over the southeastern Atlantic coast states was seen continuing to track east.
A little bit of a cooler airmass to start off Sunday, but warm advection and a favorable mixing direction means good temperature recovery for highs.
will continue to ridge back southwestward through the Ohio Valley today through much of Sunday. A rather sharp mid/upper level trof will enter the region from the west Sunday night. However, not expecting much of a surface or low level reflection with the trof.
302 AM CST Sat Nov 16 2019 As of this writing, a closed upper low over the southeastern Atlantic coast states was seen continuing to track east.
Expect mostly clear skies and light wind tonight to allow temperatures to fall back into the 30s tonight, but some higher level cloudiness moving across after midnight will likely disrupt the cooling some, and temperatures may stay above freezing at many locations.
Winds increase as a result of the pressure gradient increasing on the back side of a pre-frontal trough as the front approaches. The cold front moves across the area this evening with sprinkles to very light mostly rain showers along the front. Temperatures on Sunday will be slightly cooler in the wake of the cold front.
Building mid and upper level ridge today will result in mainly clear skies with mild temperatures. Will see an increase in clouds for Sunday though ahead of a weak cold front that moves into the region Sunday night.
Breezy day expected today, especially over western Oklahoma, with southerly flow increasing in response to upstream trough that will move across the intermountain/Rockies region into central Plains tonight. Ahead of and as this trough passes, expect an increase in mid-high level cloud cover. This trough will be accompanied by a surface front, which will progress southeast over region on Sunday.
555 AM CST Sat Nov 16 2019 Cool and dry weather will prevail across central Illinois today with afternoon highs in the lower to middle 40s. The high clouds will thicken as the day progresses, but partly to mostly sunny skies will be the rule. Given light easterly flow, afternoon highs will be a couple degrees cooler than yesterday. mainly in the lower to middle 40s. Total rainfall will be quite light: however, thick cloud cover will once again keep temps in the lower to middle 40s.
Another cold night is expected although high cirrus clouds will increase from the west as an upper trough dives southeast across the Plains and into the Mississippi River Valley. This will bring a weak cold front into the area late Sunday but a lack of deep layer moisture will likely prevent precip development.
Clouds should begin returning to the area Sunday as llvl ridging transitions ewd.
This morning will be off to a warmer start as diurnal cooling has been slow to non- existent overnight with stratus and sfc winds high enough just to keep low levels mixed. Drier air will filter back into the region on Saturday as high pressure builds to the north. The synoptic setup will be more favorable (inversion above ridgetop / stronger winds normal to / negative vertical wind shear) for possible strong downslope winds to develop this evening and overnight from the ridgetops and mid-way down east facing slopes.
High pressure aloft will return for early in the upcoming week, followed by a new Pacific storm system impacting mainly central and southern Utah midweek.
A digging upper trough over the Plains will send a cold front south and into our area during the day tomorrow. There could even be a brief period (an hour or two) of high winds through Guadalupe Pass behind the cold front. Temperatures behind the front will not really be affected with highs likely only a degree or two cooler than today for most areas. Mid level flow will transition from NW to SW by midweek ahead of a cut-off low near Baja California.
Behind yesterday's cold front passage, lingering northwest flow aloft will continue to produce showers, primarily across west-central/southwest Montana and central Idaho. Warmer air will accompany this feature, leading to increasing snow levels, up to roughly 9000 feet by Sunday afternoon. Temperatures overnight tonight should stay relatively mild with the influx of warmer air aloft and increasing cloud cover. And with ground temperatures running above freezing for most areas, the potential for freezing rain is looking less likely than previously expected.
626 AM EST Sat Nov 16 2019 Weak cold front washes out today with high pressure building in. Warmer mid week then unsettled toward the end of the work week. A weak cold front approaching from the north will yield increasing low level cloudiness across northern and western portions of the forecast area this morning before mixing out late this morning. Otherwise, just some mid and high clouds across extreme eastern portions of the area and some breezier easterly winds this afternoon along the highest ridges as an upper low makes its northerly turn up the coast off the Carolinas. Will see another cold night tonight with lows mostly in the lower to mid 20s as high pressure settles in with mostly clear skies.
330 AM CST Sat Nov 16 2019 Cool and dry weather will prevail across central Illinois today with afternoon highs in the lower to middle 40s. The high clouds will thicken as the day progresses, but partly to mostly sunny skies will be the rule. Given light easterly flow, afternoon highs will be a couple degrees cooler than yesterday. mainly in the lower to middle 40s. Total rainfall will be quite light: however, thick cloud cover will once again keep temps in the lower to middle 40s.
At sunrise most of the region should be several degrees below freezing, mainly in the mid 20s. Warmer conditions are in store for the weekend and much of the upcoming work week.
526 AM CST Sat Nov 16 2019 Looking at SKC skies as high pressure will continue to dominate the wx pattern over the weekend.
Latest surface analysis shows the warm front taking it's time to progress through central ND, with a southeast flow remaining at Bismarck and Minot at 09 UTC. Eventually the warm front will scoot eastward and a cold front will move through the forecast area today bringing breezy to windy conditions, especially southwest.
An upper trough will approach from the Plains late tonight and produce some light snow across central and northcentral Wisconsin.
516 AM EST Sat Nov 16 2019 Under mostly cloudy skies and northwest to north winds near 20 mph, temperatures are averaging in the lower 70s along the Florida Keys. A deepening surface area of low pressure just offshore of the extreme Southeast United States coast, will lift northeastward pulling an associated cold front in the extreme outer Straits of Florida further away from our region.
As of 09Z Saturday morning zonal midlevel flow was present across Central Plains, ahead of a broad trough across the Central and Northern Rockies. At the surface, a broad and weak lee trough extended across the Central and Northern High Plains. The deepening lee trough will result in a breezy day with southerly winds 10-15 MPH, gusting 20-25 MPH.
455 AM EST Sat Nov 16 2019 A moisture-starved cold front will drop southeast across state the overnight. Another area of high pressure will move north of Lake Ontario Saturday.

High pressure will build north of the region Saturday, making for a bright but chilly day in most areas with a brisk NE breeze.
A very dry air mass will filter into the region this afternoon from the northeast as high pressure builds. The synoptic setup will be more favorable (inversion above ridgetop / stronger winds normal to / negative vertical wind shear) for possible strong downslope winds to develop this evening and overnight from the ridgetops and mid-way down east facing slopes.
This wave will continue to drop southeastward, bringing slightly cooler temperatures to the region.
316 AM CST Sat Nov 16 2019 As of 09Z Saturday morning zonal midlevel flow was present across Central Plains, ahead of a broad trough across the Central and Northern Rockies. At the surface, a broad and weak lee trough extended across the Central and Northern High Plains.

Sunday: The cold front will move quickly through Sunday.
1047 AM CST Sat Nov 16 2019 High pressure remains over the Mid-South this morning. At sunrise most of the region should be several degrees below freezing, mainly in the mid 20s. Warmer conditions are in store for the weekend and much of the upcoming work week.
SHORT TERM (Now through Sunday Night): High pressure heads east through the period with a very weak frontal boundary and northerly wind shift approaching Deep South Texas and the Rio Grande Valley Sunday night. Light and somewhat variable winds overnight shifting southeast may still allow temperatures to dip into the low 50s or upper 40s north and mid to upper 50s across the RGV.
237 PM CST Sat Nov 16 2019 (Tonight and Sunday) Cooler temperatures are in store as a cold front will move across the region on Sunday. Otherwise, expect slightly cooler temperatures for tonight.
The high clouds will thicken as the day progresses, but partly to mostly sunny skies will be the rule. Given light easterly flow, afternoon highs will be a couple degrees cooler than yesterday. mainly in the lower to middle 40s. Total rainfall will be quite light: however, thick cloud cover will once again keep temps in the lower to middle 40s.
Upper trough currently pushing through the region, supporting rain showers over the SE half. Skies will clear tonight with temps dropping into the lower 30s to 20s. Precip will mainly be light rain given very warm thermal fields, save the higher elevations of the Black Hills were snow will be possible, generally less than an inch there.
246 PM EST Sat Nov 16 2019 Current radar loop shows a few showers lingering across east central GA as main low pressure center begins is way up the eastern seaboard. Clouds around the backside of the low are clearing the area from NW to SE. A weak ridge is beginning to build in over the area behind the exiting low pressure system which should keep things dry for the rest of the short term.
Cold front, currently near the Wyoming and Colorado border will sweep south through the area during the late afternoon and early evening. High temps tomorrow will be cooler than today, in the mid 50s at most locations with generally light winds. At the start, the models continue to show an upper-level ridge over the western U. along with a deepening upper-level trough over northern California and a cut-off upper low off the Baja coast.
A trough will approach the area tonight and will move east of the southern Plains by midday Sunday.
/Issued 1015 AM CST Sat Nov 16 2019/ Current forecast in good shape with warmer temperatures expected this afternoon as winds become more southerly.
A sharp upper trough will bring a small chance of light precipitation to all or parts of central Indiana Sunday afternoon and night.
Temperatures tonight will once again drop down into the lower 30s with some rural locations seeing upper 20s. Otherwise, afternoon temperatures will climb a few degrees warmer than today to near 60. With increased cloud cover, temperatures overnight remain above freezing Sunday night.
Despite full insolation today, temperatures will only top out in the 50s at most locations which is cooler than normal. Expect mostly clear skies and light wind tonight to allow temperatures to fall back into the 30s tonight, but some higher level cloudiness moving across after midnight will likely disrupt the cooling some, and temperatures may stay above freezing at many locations.
An upper level trough was moving through the Northern Rockies with an attendant cold front over the Northern Plains states. The surface cold front will dive southeastward overnight and will be just to the west of the area by early Sunday morning. Overnight lows will range from the low 30s over south-central Missouri to near 40 over extreme southeast Kansas. Highs Sunday should be slightly cooler than today due to the increased cloud cover but will still climb into the 50s.
136 PM MST Sat Nov 16 2019 Morning cold front and upper trough have moved to our east this afternoon with an upper ridge moving in from the Pacific NW.
Sunday morning should be quiet with weak surface ridging in place. Scattered showers may develop along the leading edge of a low level warm front pushing into northwest North Dakota during the afternoon.
A cold front will move into the area overnight, w/fropa KHOB/KCNM ~10Z, and thru KFST by ~14Z. A digging upper trough over the Plains will send a cold front south and into our area during the day tomorrow. There could even be a brief period (an hour or two) of high winds through Guadalupe Pass behind the cold front. Temperatures behind the front will not really be affected with highs likely only a degree or two cooler than today for most areas. Mid level flow will transition from NW to SW by midweek ahead of a cut-off low near Baja California.
Tonight a cold front will approach the area however, southerly flow out ahead of hat front will keep temperatures relatively mild tonight with lows in the mid 30s to lower 40s. Cloud cover and showers will keep temperatures cooler tomorrow with highs in the mid 40s to lower 50s.
A cold front will move through the area late tonight and Sunday morning and will shift winds to northerly. Breezy day expected today, especially over western Oklahoma, with southerly flow increasing in response to upstream trough that will move across the intermountain/Rockies region into central Plains tonight. Ahead of and as this trough passes, expect an increase in mid-high level cloud cover. This trough will be accompanied by a surface front, which will progress southeast over region on Sunday.
A cold front will arrive at the terminals before sunrise Sunday morning swinging the wind to the north and increasing speed into the 15 to 25 knot range. An upper level ridge will move across the southern Plains today with the warming trend continuing. Hot on the heels of the ridge is a quickly-moving upper level short wave trough that will drive a cold front southward through the forecast late tonight and early Sunday.
Surface temperatures should stay above the freezing mark thus keeping the predominant precip type rain and with the narrowly forced nature of this band, any light rain should be fairly short lived. Northwesterly winds and enhanced cloud cover to start the day will keep Sunday's high temperatures on the cooler side, back into the upper 30s and 40s.
