215 PM CST Mon Nov 4 2019 Another dry and quiet weather day across the mid state, with southerly flow helping temps climb into the low 60s across the area. High clouds hanging around will give way to more cloud cover overnight as the upper Midwest trough moves eastward, and the trough axis crosses our area. Models earlier had the weak cold front way to our north, but now its sagging a bit further south, yielding some rain chances in KY early Tuesday morning. This will be short lived as the trough continues to the east and clouds will be on the decrease from mid morning through the afternoon Tuesday.
1104 AM EST Mon Nov 4 2019 Currently - Water vapor imagery shows the subtropical ridge remains in place across the Gulf of Mexico and Sunshine State. A broad upper level trough situated across the eastern two-thirds of the U. Short term update - High pressure in place along with the dry layer aloft courtesy of said high will keep rain chances low for today and through the next few days.
A cold front is currently moving through the area, and is expected to continue moving south through the I-10 corridor by early Tuesday morning. For Tuesday, temperatures will be cooler behind this front, with highs mainly in the upper 60s to lower 70s. Skies will be mostly cloudy, also contributing to the cooler temperatures.
1012 AM CST Mon Nov 4 2019 A cold front is poised to move into northeast Oklahoma this morning and spread to the southeast as the day wears on.
Lows tonight will bottom out in the low to mid 30s. Highs Tuesday afternoon will peak in the low to mid 40s.
227 PM CST Mon Nov 4 2019 A prefrontal trough is shifting winds from the west and northwest sending highs to near record levels this afternoon. The cold front is still located in the Texas Panhandle and will move south overnight shifting winds from the northeast and bringing cooler temperatures. Highs tomorrow will greatly depend on cloud cover with the cooler MET showing overcast skies holding throughout the day and the warmer ECS keeping mostly clear conditions until tomorrow night. Stayed closer to the warmer guidance since it appears more likely that there will be at least some scattering of clouds tomorrow afternoon due to the very dry airmass currently in place limiting isentropic lift saturation.
High pressure will produce dry weather into the weekend at least.
1034 AM EST Mon Nov 4 2019 A high pressure centered over the mid-Atlantic states this morning is stretching towards the FL peninsula bringing in an onshore wind flow.
As the trough continues to develop Tonight, the entire coast will have a chance for convective activity. The inverted trough in the gulf will move east across region on Tuesday. In addition, the area will be in an upper trough with weak waves moving through it.
1120 AM CST Mon Nov 4 2019 Cloud cover will be on the increase today as a cold front and upper trough move into the region. A cold front moves through the area late Wed into Wed night, slowing or temporarily stalling over the southern CWA. Fri will be cooler with highs in the 40s and Sat will see highs in the 50s. Cold front starting to push into the CWA late this morning and should move through the terminal locations during the afternoon hours. Some MVFR conditions will be possible with the lower ceilings and rainfall.
The overall pattern remains locked in with the strong ridge over the eastern Pacific and the broad upper trough across the eastern two-thirds of North America.
Strong upper ridge continues off the west coast as our area remains under northwest flow aloft. Temperatures will be a few degrees warmer today, along with mostly clear skies and light winds. A surface inversion continues with stagnant conditions in the lower valleys.
206 PM CST Mon Nov 4 2019 A west coast mid-level ridge and downstream trof look to hold through much of the week.
With expected cloud cover, overnight temps should remain a few degrees warmer than last few nights.
1246 PM EST Mon Nov 4 2019 Moisture continues to stream into the area ahead of the next weak cold front that is due to pass quickly Tuesday morning.
Moisture continues to stream into the area ahead of the next weak cold front, that is due to pass quickly Tuesday morning. The only POPs I've got overnight and early Tuesday are in the upslope areas of the higher terrain of Clay, Cherokee, Monroe, and barely bleeding into Blount Counties. Tonight's temps should be the mildest in the past several nights, with Max Temps on Tuesday being a few degrees warmer than today.
At the surface, post frontal ridge axis will build southward tonight, leading to mostly clear skies, light and variable winds, and temperatures dropping to the upper 20s to mid 30s. While surface temperatures may drop below freezing in the presence of this fog, fog is not expected to be dense enough to lead to ice forming on roadways.
Dry and mild weather is expected through the upcoming week as high pressure builds across the West.
The stalled front across south Florida will be lifting north as a warm front as ridging builds in across the area at the surface and aloft through Tuesday. Temperatures will continue to moderate, with lows tonight in the upper 60s north to the lower to mid 70s central and south. Highs Tuesday in the lower 80s north to the upper 80s south.
A cold front will move through the area this afternoon and tonight, bringing a wind shift to the north across the area. A weak cold front will move through KABI this afternoon resulting in winds shifting out of the northwest around 21Z. /issued 524 AM CST Mon Nov 4 2019/ (Today and Tonight) Another weak cold front will push, from north to south, across West Central Texas today. This front will not initiate any showers or thunderstorms; however, it will bring some cooler air. The cooler air will likely produce cooler highs today, mainly across the Big Country. Elsewhere today, the cooler air won't have much impact on afternoon highs, which will likely range from around 80 to the mid 80s. For tonight, winds from the north will continue to bring cooler air into West Central Texas.
Some locations across the south have been very slow to warm, whereas northern areas, with little cloud cover, have mixed out to warmer temps very quickly.

344 PM EST Mon Nov 4 2019 Currently - Water vapor imagery shows the subtropical ridge remains in place across the Gulf of Mexico and Sunshine State. A broad upper level trough situated across the eastern two-thirds of the U. Across our CWA, isolated showers remain associated with a weak and subtle inverted trough has moved into the western waters.
945 AM PST Mon Nov 4 2019 A persistent stable and rather mild weather pattern will maintain its grip on the region as high pressure remains parked just off the Oregon and California coast.
/Issued 1012 AM CST Mon Nov 4 2019/ A cold front is poised to move into northeast Oklahoma this morning and spread to the southeast as the day wears on.
RAP analysis also indicates high 850mb moisture transport into the low level boundary. Low temperatures will be around 70 degrees inland, and in the low to mid 70s along the coast.
737 PM CST Mon Nov 4 2019 There is an low chance that weak upslope easterly flow will trigger an area of IFR conditions with stratus and fog (could be freezing fog) mainly along the edge of the caprock. That said, given the low confidence and probability of this occurring, we continue to show VFR conditions through the TAF period. At the surface, post frontal ridge axis will build southward tonight, leading to mostly clear skies, light and variable winds, and temperatures dropping to the upper 20s to mid 30s. While surface temperatures may drop below freezing in the presence of this fog, fog is not expected to be dense enough to lead to ice forming on roadways.
Upper level trough aloft will continue to bring weak onshore winds and cool overnight temperatures through the middle of the week. Then, a high pressure ridge will allow for warm temperatures to return to the area going into the weekend.
Thermal parameters support rain, but can't totally rule out some sleet or even snow mixing in with the stronger showers as surface wet bulbs lower near freezing. Decreasing clouds are then expected overnight, as high pressure builds in.
A west coast mid-level ridge and downstream trof look to hold through much of the week.
334 PM CST Mon Nov 4 2019 A long wave trough will remain over the Upper Midwest into mid November, with northwesterly mid to high level flow across the high plains and upper level ridging near the West Coast.
538 PM EST Mon Nov 4 2019 Rain is expected with a crossing cold front later tonight and part of Tuesday.
747 PM EST Mon Nov 4 2019 High pressure will move farther away from the region tonight with a weak trough off the SE Coast through Tuesday. A front will move through the area Tuesday with most of the moisture associated with the trough and ahead of the cold front remaining east of the forecast area.
The pattern has changed little over the last several days with western Montana and central Idaho sandwiched between high pressure to the west and low pressure to the east.
If this occurs at night then low temperatures could be upwards of 5-10 degrees warmer than the forecast considering a broken or overcast deck during the predawn hours.
338 PM CST Mon Nov 4 2019 Cold front is slowly making it's way south across the forecast area as of 20z. As for temperatures, decent cold air advection, but temperatures will remain above freezing where the precipitation is occurring, so it will remain in the form of rain before tapering off towards daybreak on Tuesday.
Cold front is slowly moving the area this afternoon however compressional warming along the front has allowed temperatures to warm quite nicely across the southern South and Rolling Plains. With the slightly cooler airmass in place, temperatures will fall a few degrees below what was experienced this morning.
526 PM CST Mon Nov 4 2019 00Z TAF issuance VFR will continue this evening even as a weak cold front moves across the region. /issued 227 PM CST Mon Nov 4 2019/ A prefrontal trough is shifting winds from the west and northwest sending highs to near record levels this afternoon.

WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO At 1 PM, water vapor satellite showed and upper-level ridge centered off the northern CA coast and a cut off low centered just off the southern CA coast.
622 PM EST Mon Nov 4 2019 High pressure will move farther off the coast through tonight. A trough will be near the coast tonight into Tuesday ahead of an approaching cold front. Most of the moisture associated with the trough and ahead of the cold front will stay east of the forecast area.
High pressure will bring dry conditions all the way through the weekend.
/Issued 358 PM CST Mon Nov 4 2019/ Moisture has been steadily advecting into the area over the last 24 hours with many locations across E OK and NW AR seeing dew points in the low to mid 50s. A weak cold front will move through the area this evening allowing for lift to occur within this fairly moist airmass across much of the area. This cold front will likely stall in northern Texas Tuesday morning before moving northward bringing a wealth of moisture behind it.
Further west towards the Front Range, less cloud cover has allowed for warmer temperatures around Denver. Flow aloft will turn more westerly Tuesday night while the low level pressure gradient increases as a lee trough develops.
More possible will be the chance for a quick burst of snow along the cold front that its progged to push through the area overnight Tuesday.
As the jet slides east, a warm front will lift north and east through the area tonight with southwest winds increasing along the western foothills. The aforementioned warm front will generate some light precipitation over eastern areas tonight into Tuesday. Otherwise, mainly dry and warmer conditions can be expected across the area on Tuesday before yet another Canadian cold front drops in during the evening.
As a cold front drops southward through the region, scattered showers will affect areas along and south of a Danville to Taylorville tonight. A cold front extending from around Champaign to Taylorville will continue to press southeastward overnight, bringing a colder air mass back into central IL with lows tonight ranging from 30 in Galesburg to 39 in Lawrenceville. A long wave trough over much of the eastern half of the country will remain centered over the midwest through the upcoming week. A series of cold fronts embedded in generally northwest flow associated with the trough will move through central IL bringing progressively cooler conditions.

Weak cold front. ahead of the the upper level trof axis. The light ongoing precip should also shift east and southeast during the night and exit the CWA early Tuesday morning as the warm advection and upper trof axis exit the region. Behind the trof axis. low temps tonight look to fall into the mid 30s near the Kansas border to the mid 40s near Interstate 40 to the low/mid 50s near the Red River. have adjusted hourly pop/wx/sky/temp/dewpoint/wind grids for tonight into Tuesday morning to account for the timing and movement of the front and trof axis.
1035 PM CST Mon Nov 4 2019 06Z TAF issuance The cold front is currently situated from KHOB to KODO to KSJT.
149 AM EST Tue Nov 5 2019 High amplitude U/L pattern will persist across North America with a broad L/W trough extending generally east of the Rockies. with a sharp U/L ridge off the west coast of the U. U/L disturbances will ride through the mean U/L flow reinforcing the broad L/W trough through the period. A warm front extends across the central Florida peninsula and will become quasi-stationary as it becomes parallel to the U/L flow.
1028 PM MST Mon Nov 4 2019 A broad upper trough covers much of the CONUS, with northwest flow over the northern plains.
There will also be a weak warm front aloft lifting northeast tonight. A cold front will drop into northern Nebraska after midnight.
320 AM EST Tue Nov 5 2019 Cold front has made it very close to the Ohio River, with right- entrance jet dynamics providing enough lift to support a precip shield behind the front. Temps will be slow to get up off of morning lows given modest cold advection and fairly substantial cloud cover through midday, but we should get enough sunshine later in the afternoon to recover into the lower/mid 50s, roughly 10 degrees below normal. High pressure settles overhead tonight, supporting favorable radiational cooling conditions and similarly below normal temps.
/issued 405 PM CST Mon Nov 4 2019/ A cold front/northerly wind shift is gradualy moving through the area today. As the cold front approaches southeast Oklahoma, scattered showers are possible this evening/tonight.

1108 PM CST Mon Nov 4 2019 As of this afternoon, most of the notable showers with the upper trough have moved through the local area.
The wx pattern is fairly quiet this Mon evening across the cntrl TN Valley, as high pressure remains layered across the mid/srn Atlantic states. This additional cloud cloud cover is aligned with a reinforcing cold front that will move ewd thru the area during the day Tue. Otherwise, current temp trends in the mid 40s/lower 50s should fall more into the lower 40s overnight for most spots, with some continued mid/high clouds.
A cold front moves through the area late Wed into Wed night, setting the stage for a decent precip event. Fri will be cooler with highs in the 40s and Sat will see highs in the 50s. Models show a cold front moving through on Sun, with the coldest air overhead Sun night into Mon night.
1029 PM MST Mon Nov 4 2019 Isolated areas of precipitation remain along the western Nebraska Panhandle, but for the most part, the High Plains and neighboring High Terrain is clearing out, leaving an area of low level moisture and snow at the surface. Still on track for a warmer, drier, breezier day tomorrow.
305 AM EST Tue Nov 5 2019 The latest regional surface analysis indicates weak high pressure over the Appalachians with continued bridging through North GA.
High pressure will build across the region this weekend creating warmer and dry weather, and less low clouds along the coast. WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO A couple patches of fog have developed in some of the cooler drainages along the coast this evening such as oceanside and Imperial Beach, but some of it has already begun to push back offshore. Weak mid-level east flow on the north side of the closed low off the coast of northern Baja and weak offshore surface pressure gradients should keep low clouds and fog limited to the beaches and up to a few miles inland, likely drifting back out to sea by tomorrow morning.
1130 PM CST Mon Nov 4 2019 VFR conditions will lower to MVFR as a cold front tracks through the state through the period, bringing rain chances with lower ceilings and visibility.
1044 PM EST Mon Nov 4 2019 Water vapor imagery highlights a broad expanse of subsidence over the Western Caribbean associated with a well-formed mean layer ridge. High pressure centered east of the Delmarva stretches southwest into the southern United States.

415 AM EST Tue Nov 5 2019 Showers will spread across the area today before exiting this afternoon with a passing cold front.
A low pressure system will bring a chance for showers and thunderstorms mainly to areas east and southeast of Flagstaff late tonight through Wednesday night. Some cumulus development will occur across the White Mountains this afternoon as some moisture sneaks in ahead of an approaching low pressure system. Better dynamics and moisture will arrive on Wednesday as the low crosses the region, with chances for showers and thunderstorms mainly from Flagstaff eastward. One trend that has been noted this morning is guidance indicating the low will track slightly farther south. Models are in better agreement that the low will quickly eject to the east on Wednesday night.
Locations north of I-90 looks to remain cold enough for snow throughout the day, where as locations closer to Sioux City may see periods of rain given warmer air in the low levels. Freezing rain and drizzle look less likely than in previous forecast, given decent saturation of the dendritic growth zone during precipitation timeframes. That being said, the higher amounts are more likely further east in south-central MN and north-central IA. A cold front will push through the region on Wednesday, bringing a return of chilly north winds and additional opportunities for flurries and light snow.
GKS The chance of rain will increase Wednesday night as upper level divergence intensifies ahead of an approaching upper level trough and over a strong southward moving cold front.
