215 PM EST Tue Nov 19 2019 Broad upper-level troughing will maintain cooler temperature along with patchy drizzle today. Drizzle or freezing drizzle may be possible late tonight before warmer temperature returns during the second half of the week.
Upper ridging holds on across the area Wednesday as a long wave trough remains over the western conus.
Northern trough- southern low pattern has started pushing moisture into the forecast area. But just where the boundary is has now varied from staying in the highlands in that area, to now including portions of the Snake River plain, where now snow appears possible Wed night, as much as a half inch in the city and higher amounts in the bench areas. Dry conditions continue through the weekend, but increasing cloudiness develops late Sat night as the next incoming trough makes its approach. This winter storm, that arrives in force for lat Sun and Mon, is stronger than the previous Tue-Wed storm, and widespread snow is likely for this event with temperatures even at Snake River plain elevations struggling to get above freezing. A cold front is expected to push through this evening.
240 PM CST Tue Nov 19 2019 A very nice fall day today will continue tomorrow as an upper level ridge and southerly low level winds bring WAA to the area.
Issued by National Weather Service Albuquerque NM 1114 AM CST Tue Nov 19 2019 VFR conditions prevail and are forecast to persist with increasing southerly flow due to a deepening lee side trough and approach of a Baja low/trough from the southwest.
Clear skies and dry weather will continue through the evening and into the morning as the trough passing over northeast Georgia and and the Carolinas moves off to the east, resulting in the clearing out of the remaining clouds over southeast Georgia while high pressure further builds in over the region. Overnight low temperatures will be in the lower to mid 40s for inland areas and in the upper 40s and lower 50s for along the coastline and the St Johns River.
1020 AM MST Tue Nov 19 2019 A more active period begins on Wednesday following the passage of a cold front and a complex series of low pressure centers working their way east of the Rockies.
1033 AM EST Tue Nov 19 2019 High pressure will gradually build in from the west through the middle of the week.
Especially with the low dew points and slacking and veering wind late. /Today through Wednesday afternoon/ Upper-ridge to prevail through most of the short term forecast period. Showers possible across southeast Oklahoma and northeast Texas late Wednesday afternoon ahead of a cold front. Otherwise, afternoon high temperatures on Wednesday to climb into the low to mid 70s.
Highs on Wednesday will be fairly similar to today in the mid 70s to lower 80s, if not a degree or two cooler from clouds.
A weak disturbance on the back-side of the trough may lead to a slight chance of light showers in the higher elevations of far northeast Georgia during the overnight hours, although no rainfall accumulations are expected at this time. Temperatures through the rest of the day and tomorrow will run near climatological normals, with highs mainly ranging from the low to the mid 60s and lows mainly ranging from the upper 30s to the mid 40s.
1127 AM CST Tue Nov 19 2019 The overall weather pattern will be transitioning to more active and warmer weather as upper ridging builds into the central CONUS ahead of our next weather maker. Temperatures will remain above normal this afternoon in the middle 50s to the lower 60s. Highs in the lower to middle 60s on Wednesday will potentially be some of the warmest observed readings this November thus far.
An upper level ridge will move east across the Plains today and then over the region on Wednesday. A warm front will move north this afternoon and return southerly winds to the area.
111 PM EST Tue Nov 19 2019 Broad upper-level troughing will maintain cooler temperature along with patchy drizzle today. Drizzle or freezing drizzle may be possible late tonight before warmer temperature returns during the second half of the week.
Generally light snowfall is expected across the mountains, with rain prevailing in the lower elevations. The approaching trough is still expected to split as it approaches the western forecast area boundary, with low pressure diving south. The approaching trough will keep mixing conditions present today and into Wednesday.
Unfortunately, a quick hitting cold front is on the front doorstep (currently crossing the Tennessee River). Although we'll be behind the cold front.
333 PM CST Tue Nov 19 2019 Tonight and Wednesday: Clear and warmer than average conditions will continue for the rest of the evening throughout the area. Upper level heights will continue to increase through the night as an upper ridge moves into the region from the west. Clear skies and light winds tonight will aid the radiational cooling effect, helping temperatures in the region to fall into mainly the low 40s. Expect highs to remain above average and could be 1 to 2 degrees warmer than today.
845 PM CST Tue Nov 19 2019 Northwest flow aloft on the backside of the trough lifting across the Mid-Atlantic States will bring some high clouds through the region tonight. Mild pacific high pressure is building over the region. Temps will drop into the mid 30s toward the TN River to the lower 40s over the MS Delta. High pressure will push east on Wednesday and winds will turn SE with another mild day on tap. A cold front will approach Wednesday night.
218 PM MST Tue Nov 19 2019 Water vapor shows dirty ridge extending through the northern Rockies into the northern plains, with splitting trof along the west coast. East-southeast surface winds are in place in between ridge over the far eastern Dakotas and lee trof along the Rocky Mountain front. Northern Stream trof quickly advances into the northern Rockies by late tonight with surface front pushing into our western zones. Best chance for freezing drizzle will be across northeast WY and northwest SD, but there is some chance that temps could fall near or below freezing further south on the SD plains during the day, and subsequently result in freezing drizzle. Deeper moisture should arrive later in the day and evening to switch any freezing precip over to snow.
The closed 500 mb low off Baja will combine with a developing trough as the trough digs down the CA coast tonight. As the remnants of the cutoff in incorporated into the trough and lifts NE over AZ, significant moisture and lift spread over the Four Corners area a bit after midnight tonight then spread north over central CO and all of eastern UT by about 15z, and finally reaching northern CO by 18z. Widespread rainfall will affect all the lower elevations with the rain/snow line at 8000-8500 feet.
443 PM MST Tue Nov 19 2019 Water vapor shows dirty ridge extending through the northern Rockies into the northern plains, with splitting trof along the west coast. East-southeast surface winds are in place in between ridge over the far eastern Dakotas and lee trof along the Rocky Mountain front. Northern Stream trof quickly advances into the northern Rockies by late tonight with surface front pushing into our western zones. Best chance for freezing drizzle will be across northeast WY and northwest SD, but there is some chance that temps could fall near or below freezing further south on the SD plains during the day, and subsequently result in freezing drizzle. Deeper moisture should arrive later in the day and evening to switch any freezing precip over to snow.
Mild pacific high pressure is building over the region. Temps will drop into the mid 30s toward the TN River to the lower 40s over the MS Delta. High pressure will push east on Wednesday and winds will turn SE with another mild day on tap. A cold front will approach Wednesday night.
Water vapor imagery clearly shows two upper lows along the California and Baja coasts.
/15/ Tonight and Wednesday: Clear and warmer than average conditions will continue for the rest of the evening throughout the area. Upper level heights will continue to increase through the night as an upper ridge moves into the region from the west. Clear skies and light winds tonight will aid the radiational cooling effect, helping temperatures in the region to fall into mainly the low 40s. Expect highs to remain above average and could be 1 to 2 degrees warmer than today.
732 PM EST Tue Nov 19 2019 An upper level trough will lift away from the Midlands tonight and bring clearing in its wake late tonight.
Once the fog dissipates, a partly sunny and mild day is anticipated on Wednesday with afternoon high temperatures topping out in the lower to middle 50s. Overnight lows will be in the lower to middle 30s. Once the morning fog dissipates, a partly sunny and mild day will be observed on Wednesday with afternoon highs in the lower to middle 50s.
The transit of these east winds may end up being the prime focal point for 2-3 hour period of light snow, favoring the lower Clark Fork region, including Highway 200 west of Ravalli, Highway 93 Arlee to Evaro Hill, and I-90 west of the Missoula Valley.
554 PM EST Tue Nov 19 2019 An area of large high pressure will remain across the Southeast U.
This wave will bring a cold front into the forecast area during the afternoon.
208 PM MST Tue Nov 19 2019 A more active period begins on Wednesday following the passage of a cold front and a complex series of low pressure centers working their way east of the Rockies.
For Tuesday afternoon and evening, warmer than normal temperatures are expected to continue.
In the northeast, status has stubbornly remained with cooler readings in the 40s. Given the proximity of the ridge, slackening winds are expected into the evening becoming light and variable.
853 PM EST Tue Nov 19 2019 Another cool night expected with clear skies along with light and variable surface winds under high pressure along the northern Gulf Coast.
655 PM EST Tue Nov 19 2019 Drizzle or freezing drizzle may be tonight before warmer temperature returns during the second half of the week.

532 PM CST Tue Nov 19 2019 A very nice fall day today will continue tomorrow as an upper level ridge and southerly low level winds bring WAA to the area.
As of 2 PM CST, temperatures were in the mid to upper 70s inland, in the low 70s along the Barrier Islands. The model blends have been on the cooler side, thus had to manually increase a degree or two from the previous forecast.
As the high propagates into our region our heights are expected to rise, which will in turn lead to slightly warmer temperatures overnight than what has been observed over the past few evenings. Temperatures are expected to be in the low to mid 40s across much of the region, with coastal areas potentially holding on to the low 50s due to the warm waters still observed in the shelf waters. Ridging will prevail through the period with no rainfall forecast.
1033 PM EST Tue Nov 19 2019 Have been watching a reinforcing cold front spread south through the Keys this evening. It is being pushed along by strengthening and expanding high pressure that is near the northern Gulf Coast this evening. This will be our driest air mass so far this fall, with dewpoints expected to bottom out in the lower to mid 50s on Wed afternoon.
1221 AM EST Wed Nov 20 2019 Weak high pressure will bring mainly dry weather today.
/15/ Prior discussion below: Tonight and Wednesday: Clear and warmer than average conditions will continue for the rest of the evening throughout the area. Upper level heights will continue to increase through the night as an upper ridge moves into the region from the west. Clear skies and light winds tonight will aid the radiational cooling effect, helping temperatures in the region to fall into mainly the low 40s. Expect highs to remain above average and could be 1 to 2 degrees warmer than today.
Clear skies and dry weather will continue through the evening and into the morning as the trough passing over northeast Georgia and and the Carolinas moves off to the east, resulting in the clearing out of the remaining clouds over southeast Georgia while high pressure further builds in over the region. Overnight low temperatures will be in the lower to mid 40s for inland areas and in the upper 40s and lower 50s for along the coastline and the St Johns River. High pressure will continue to dominate weather conditions through midweek as ridging from out of the west builds in over the region. High temperatures for midweek will range between the upper 60s and the lower to mid 70s, with temperatures becoming gradually becoming warmer as the week progresses.
1126 PM CST Tue Nov 19 2019 A very nice fall day today will continue tomorrow as an upper level ridge and southerly low level winds bring WAA to the area. The passing of the cold front will allow a cooler airmass to advect into the region.
145 AM EST Wed Nov 20 2019 High pressure build in today, remaining into Thursday.
This wave will bring a cold front into the forecast area during the afternoon. This system is a little cooler and much of the area will have snow by late in the evening.
Upper ridging holds on across the area Wednesday as a long wave trough remains over the western conus. Rain chances will continue Thursday as the cold front moves through the region. Ample gulf moisture will be pulled northward, with more rain expected across the area, the higher chances and greater amounts will be near the front over southern Missouri.
/issued 845 PM CST Tue Nov 19 2019/ Northwest flow aloft on the backside of the trough lifting across the Mid-Atlantic States will bring some high clouds through the region tonight. Mild pacific high pressure is building over the region. Temps will drop into the mid 30s toward the TN River to the lower 40s over the MS Delta. High pressure will push east on Wednesday and winds will turn SE with another mild day on tap. A cold front will approach Wednesday night.
Highs should top out in the mid 50s in northeast Nebraska and the low 60s near the KS/MO borders. Cooler air wrapping in behind the system will allow rain to mix with and potentially change over to snow as the system moves out Thursday morning. Lingering showers should move out of the area late Thursday morning, with dry conditions anticipated Thursday afternoon as high pressure builds back into the region.

Afternoon temperatures will be in the mid 30s to mid 40s in the mountains and adjacent valleys and around 50 in the lower elevations--a couple of degrees less than today. High pressure aloft will build over WA and OR but will be undercut by a closed low over the desert southwest on Thursday.
Closed low forming over California will shift clouds northward tonight. Fog development will be limited tonight with a decent pressure gradient forming behind the low for light northerly winds. Blocked flow across the southern US will cause high pressure to settle over the region from Thursday through the weekend.
1242 AM EST Wed Nov 20 2019 An upper level trough will lift away from the Midlands tonight and bring clearing in its wake late tonight. High pressure and dry air will return tonight through Thursday night.
Water vapor imagery clearly shows two upper lows along the California and Baja coasts. Evening conditions should remain quite mild though windy in the warm sector with the passage of a modified cold front in the overnight hours dropping temperatures into the 40s and lower 50s with steady temps through much of Thursday via moderate CAA and some lingering cloud. The strength and impact of the secondary low remain quit variable but a rather dry lower troposphere is the rule as the weak surface anticyclone remains in place.
Milder temperatures and periods of rain will then follow by Thursday and Thursday night as low pressure tracks through the Great Lakes region.
Highs will reach into the low to mid 40s. Milder temperatures and periods of light rain will follow Thursday and Thursday night as low pressure tracks through the Great Lakes region. Light rain along prefrontal trough will overspread the area Thu followed by weak post frontal cold advection Fri. Pessimistic about much clearing later today given the strength of the inversion and the unlikelihood of the lower layers being able to mix out as insolation is limited this time of year.
This moisture will precede a storm system and cold front that will move across the region on Thursday.
Meanwhile, an upper level low dips down into the western U.
1030 PM EST Tue Nov 19 2019 Reinforcing cooler and drier air and diminishing winds overnight will produce the coolest temperatures so far this season with lows in the mid to upper 40s. Urbanized locations will hold in the lower 50s. On Wednesday, winds veer northwest to north as high pressure pushes east across the southeast U. A cool breeze but full sunshine will produce max temps in the low to mid 70s. Winds will veer North Wed as high pressure pushes east across the southeast U.
This afternoon a northwesterly flow was present aloft over Arkansas, with a trof across the eastern seaboard, and a trof along the west coast. Ridging will occur over Arkansas tomorrow as the pattern advances, and a number of disturbances will start to stream across the area Wednesday night and Thursday. At the surface, high pressure will move to the east, and allow warm air advection to increase across the area tomorrow. On Thursday a cold front will drop down across the plains, and will slowly begin to stall out across northern AR.
A deep longwave trough will be positioned over the western CONUS Wednesday morning.
Around 8pm this evening, temperatures were rapidly falling from west to east as the cold front pushes east. There remains a small chance for freezing precipitation for the southeast zones Wednesday morning, but chances for any precipiation looks too small at this point for highlights. Split upper trough will close-off over the Desert SW while the northern system moves to our east Wednesday. High pressure overhead will allow for a cold night Wednesday Night, especially if clouds can clear.
1247 AM EST Wed Nov 20 2019 An area of large high pressure will remain across the Southeast U.
In addition to the low clouds/br some -dz will also be possible, but chances were too low to mention in the TAF. Highs on Wednesday will be fairly similar to today in the mid 70s to lower 80s, if not a degree or two cooler from clouds.
Thursday will be much colder with highs only in the mid 20s, in western MN, to the low 30s, west of the Missouri River.
Showers have begun to spread east of New Mexico as the sharp trough over Arizona will continue its evolution into an open wave as it pushes northeast across West Texas into the Central Plains through the course of the day. A cold front will push south through our CWA tomorrow morning behind the exiting upper level disturbance affecting us today.
Thursday will be much colder with highs only in the mid 20s in western MN, to the lower 30s west of the Missouri River.
High pressure building in across much of the Southeastern U. It was chilly this morning, woke up to temps in the low 40s across much of the rural interior and suburban areas around the cities. This afternoon expect sunny skies and highs to reach the low to mid 70s. Boating conditions continue to improve as high pressure settles into the area.
A reinforcing cold front has cleared the area overnight, resulting in breezy north to northeasterly surface flow ushering in continental air from the Florida Peninsula. Temperatures range from the lower 60s in the far Upper Keys to 72 degrees at the Key West International Airport at 4 AM, with dew points down to the mid 50s all along the island chain.
Dry weather pattern will continue today with a modest ridge aloft over the forecast area and moisture remaining limited through the low and mid levels.
453 AM EST Wed Nov 20 2019 Dry conditions and a warming trend is expected before precipitation and cooler conditions return at the end of the week.
/issued 429 AM CST Wed Nov 20 2019/ High pressure is currently building over the region. A longwave ridge is centered over CONUS and will continue to build east. Skies are clear with calm winds which has helped temperatures drop down into the low 30s to low 40s across the County Warning Area. As the high moves east, winds will switch out of the south- southwest which will help bring in slightly above normal temperatures across the south. A pre-frontal trough will spark scattered showers across the area on Thursday. The good news is, it won't be a completely rainy day as the ridge will be reluctant to move east with a meridional pattern in place.
Rain chances to increase overnight mainly across the I-30 corridor as a cold front drifts southeast across these areas. Otherwise, temperatures on Thursday to average in the low to mid 70s.
750 AM EST Wed Nov 20 2019 High pressure will build in from the OH Valley today, bringing mainly fair weather that will continue into Thursday.
Large scale pattern consisting of a longwave trof situated over the west coast with two distinct embedded circulations. Meanwhile, an area of low pressure was beginning to organize over the central high plains.
A chance of light snow or mixed precip will remain possible into this afternoon as an upper trough moves through the forecast area. High pressure moves into the area tonight with dry weather. It is uncertain how quickly the low clouds will clear overnight which will affect how cold it will be.
A cold front will enter northeast Oklahoma early Thursday and push slowly southeast across the area.
401 AM EST Wed Nov 20 2019 High pressure will build in from the OH Valley today, bringing mainly fair weather that will continue into Thursday.
847 AM EST Wed Nov 20 2019 Dry stable conditions courtesy of high pressure building in over the area will support very pleasant dry weather across the entire forecast area the remainder of today with ample sunshine expected. After a cool start with readings in the 40s and 50s temperatures will rebound quickly with highs topping out in the lower 70s north, and mid to upper 70s central and south during the afternoon. Tranquil boating conditions will continue across the Gulf waters the remainder of today as high pressure remains in control with north winds around 10 knots and seas around 2 feet.
At the surface, lee troughing will deepen from northeastern NM into western Kansas, increasing southerly flow and moisture in the lower levels. The combination of the upper level trough and increasing moisture/instability is expected to result in scattered showers and thunderstorms later today, especially across the Big Country.
Highs will reach into the low to mid 40s. Milder temperatures and periods of light rain will follow Thursday and Thursday night as low pressure tracks through the Great Lakes region. Light rain along prefrontal trough will overspread the area Thu followed by weak post frontal cold advection Fri. Still pessimistic about much clearing later today given the strength of the inversion and the unlikelihood of the lower layers being able to mix out given the strength of the inversion and given limited insolation for this time of year.
401 AM EST Wed Nov 20 2019 High pressure will build in from the west through Thursday.
645 AM EST Wed Nov 20 2019 Dry conditions and a warming trend is expected before precipitation and cooler conditions return at the end of the week.
A drying trend with chilly nights but warmer afternoons over the weekend. Portions of our corner of the state will lose some of that today as the low shears into an open wave and lifts into the east central Rockies. A strong convective band will form on the eastern flank of the low and push through our area this evening. The low will lift toward the AZ/UT border by Thursday night with mountain snow diminishing considerably after that.
