332 AM EDT Wed Apr 4 2018 High pressure builds into the area today, but tight pressure gradient will make for gusty winds. Another cold front pushes southeast later this week. Cold front will be coming through the region this morning and as of 330 am the front was just entering SE Ohio. Behind the front, high pressure will be building in, but winds will be quite gusty with CAA and tight gradient. High pressure generally through the period with below normal temperatures.
300 AM MST Wed Apr 4 2018 The storm track will remain well to the north through the week resulting in dry conditions and warmer than average temperatures with highs in the lower 90s across the lower deserts.
154 AM EDT Wed Apr 4 2018 A cold front will move through the region tonight.
504 AM CDT Wed Apr 4 2018 Cooler/drier air is making its way into SE TX this morning in the wake of the overnight cold front and its associated storms. We will be seeing a series of cold fronts sweep across the area (some with rain, some without) through this forecast cycle. All of this appears to be courtesy of the persis- tent NW flow aloft as the weak ridging out west holds in place. The next cold front is progged for Fri night/Sat morning as scat- tered POPS return to the area. ) The next cold front is still progged for Mon and should be relatively dry, given the shorter return moisture timing. High pressure will quickly slide east turning winds east and then southeast tonight/Thursday.
with primary concerns the near or sub-freezing temps. with just the far NW portions seeing temps drop to near or around freezing. Do think continued CAA will allow temps to drop to near or just below freezing for several areas within the Freeze Warning already in place. though some SE winds will keep most areas above freezing once again. Will issue a new Freeze Warning for the far NERN counties due to this area being most likely to see near or subfreezing temps.
Expect highs today in the 20s across much of the area, with the exception of the south central where downsloping northwest flow should allow temperatures to climb into the low 30s.
Shower coverage should quickly decrease this morning as drier air in the lower levels overspread the region. However, most of this may be confined to the I-80 corridor and the ridges. Winds will subside during this evening as high pressure builds in and daytime mixing is cut off. With the mid level trough axis holding strong across eastern Canada, high pressure has a tough time turning the winds west then southwest so clouds will be around the better part of Thursday as well. Low pressure riding up to our west will bring another quick hitting storm through.
510 AM CDT Wed Apr 4 2018 With the return of southerly flow at the surface, the Panhandles should see slightly warmer temperatures today than yesterday. The gentle northwest flow aloft today will begin to strengthen Thursday as ridging in the west strengthens. Lee side troughing also strengthens Thursday and continues the warming trend. A weak cold front looks to make it into the area Thursday afternoon.
544 AM EDT Wed Apr 4 2018 A cold front currently moving into the Upstate will move through the forecast area this morning along with showers and a few thunderstorms.
328 AM CDT Wed Apr 4 2018 Today will start off chilly, with temperatures in the low 30s this morning warming to the low 60s this afternoon. Surface winds will shift to the south today and then to the southwest as lee troughing strengthens on Thursday. Downsloping winds will help warm temperatures to the the low 80s on Thursday afternoon.
Drying in the low levels will bring clearing skies Wednesday morning.
Updated aviation discussion The storm track will remain well to the north through the week resulting in dry conditions and warmer than average temperatures with highs in the lower 90s across the lower deserts. With upper level heights and thicknesses running a bit higher than average the temperatures will follow, especially in the afternoon where highs will run 6-12 degrees warmer than average through the next seven days. As we enter the weekend a deep trough will approach the west coast resulting in plenty of wind and rain for the coastal region and further inland north of central and southern Arizona.
636 AM EDT Wed Apr 4 2018 High pressure will build in the lower Ohio Valley today and then track east through the Ohio and Tennessee Valleys tonight and early Thursday.
Road temps are expected to warm a bit today to above freezing from the road temp forecasts, and with any precip very light dont forsee any issues.
752 AM EST Fri Jan 19 2018 A large area of high pressure centered over the Lower Mississippi Valley will maintain fair skies for the next few days.
935 AM EST Fri Jan 19 2018 High pressure centered over the Gulf Coast states will extend up into the region through Saturday.
An upper ridge axis moves across the area today, then increasing southwesterly flow aloft increases downslope heating tomorrow as a deep upper trough approaches the region.
The Surface Analysis places the frontal boundary south of Montana, but the upper trough to the west is sending mid-level clouds across the Montana high plains. Templer Previous update: 5 am update: Given continuing light precipitation across southern and eastern zones combined with ground temperatures hovering around freezing, icy road conditions are still expected in some areas this morning. While temperatures are above freezing over much of the area, ground temperatures are around freezing in many cases. The weekend ahead will feature a split trough moving over the region with the colder air from the northern stream affecting northeast Montana.

The majority of the energy with this trough will stay south of the area.
900 AM EST Fri Jan 19 2018 High pressure will move slowly east from the Southeastern United States into the Western Atlantic waters through tonight. Maximum temperatures on Saturday are forecast to rise to the lower 70s, just shy of average for this time of year.
708 AM EST Fri Jan 19 2018 High pressure will move east through the southeast states this weekend.
317 AM MST Fri Jan 19 2018 Current surface shows weak cold front across eastern Montana into northern Wyoming. Low level thermal ridge shifts east today as weak cold front slides through forecast area. Upper trof moving into western CONUS slides through the Rockies on Saturday, with cut off low developing over the four corners region.
633 AM EST Fri Jan 19 2018 Clear skies and light winds for most of this period as surface ridging dominates the scene. The way this moisture gets directed around ridge, all three sites will have moisture hitting at about the same time.
429 AM CST Fri Jan 19 2018 A weak frontal boundary associated with an area of low pressure will bring northwesterly winds into the CWA today.
558 AM CST Fri Jan 19 2018 January thaw that started from I-57 west yesterday, will occur over eastern IL too today as temperatures warm into the lower to mid 40s this afternoon. 1030 mb high pressure across the Gulf Coast States will stay across the southeast states today, keeping central IL with breezy ssw winds of 10-18 mph and gusts of 20-25 mph. 992 mb low pressure over southern Manitoba will track east to the southern tip of James Bay Canada by midnight tonight and bring a cold front down into far northern IL overnight. Lows tonight just below freezing, ranging from 28 to 32F. Highs Saturday in the low to mid 40s, held back some from increasing low level clouds.
927 AM EST Fri Jan 19 2018 A large area of high pressure will build east across the southern United States today and eventually move off the east coast.
844 AM EST Fri Jan 19 2018 High pressure will maintain dry and warmer weather through Saturday. Intensifying warm advection under building upper high pressure in advance of a Cntrl Rockies-to-Plains low will drive Upper Ohio temperature well above the averages for the start of the new week.
High clouds will be one fly in the ointment that could keep us from getting even warmer. Temperatures should cool back off to below freezing tonight, but believe we may be a few degrees warmer than most guidance values. However, the wind will be out of the north or northeast, which is why we expect it to be noticably cooler than on Friday.
High pressure spreading into the extreme southeastern United States is generating a gentle to moderate northeast background flow, with the highest winds over the Florida Straits. Short Term Update - As South Florida warms and the high continues to spread southeastward, winds will try to shift northeast and east northeast. High pressure spreading southeast and eastward across Florida and the southeastern United States will maintain moderate breezes across Keys Waters. Over the next couple of days the high pressure to our north will elongate eastwards into the Atlantic. This will keep Keys waters on the edge of the higher wind belt on the ridges southern periphery. This along with the cooler waters will keep winds strongest on the Florida Straits, and weaker over the cooler northern waters.
436 AM MST Fri Jan 19 2018 Southwest flow aloft will increase throughout today continuing the warmer than normal high temperatures. Its surface cold front will move across the eastern Uinta mountains after about 4 pm this afternoon and reach extreme northwest Colorado this evening. The cold front stalls over central Utah tonight and Saturday morning so unsure how much snow will fall over NE Utah until the front passes. Saturday afternoon it looks like the upper trough will start moving more steadily east, which should push the cold front into extreme western CO late Saturday afternoon.
443 AM MST Fri Jan 19 2018 Southwest flow aloft will increase throughout today continuing the warmer than normal high temperatures. Its surface cold front will move across the eastern Uinta mountains after about 4 pm this afternoon and reach extreme northwest Colorado this evening. The cold front stalls over central Utah tonight and Saturday morning so unsure how much snow will fall over NE Utah until the front passes. Saturday afternoon it looks like the upper trough will start moving more steadily east, which should push the cold front into extreme western CO late Saturday afternoon.
524 AM CST Fri Jan 19 2018 Southwesterly winds will continue to bring warmer temperatures in to the region through today. The combination of cold ground or remaining snow cover, warm moist air and a flat upper level ridge moving across the plains will combine to produce low stratus and the potential for widespread fog across the region tonight. Southerly surface flow will continue through the day Saturday allowing temperatures to climb into the lower to middle 50s as a storm system develops and begins to move across the plains.
While temperatures are above freezing over much of the area, ground temperatures are around freezing in many cases. The weekend ahead will feature a split trough moving over the region with the colder air from the northern stream affecting northeast Montana.
Ridging will continue through tonight but weaken some with the center shifting to the east.
537 AM CST Fri Jan 19 2018 Today through Saturday will be quiet with warmer than normal temperatures, with a weak upper level ridge over the area. Lows in the 20s tonight put us well above normal, with our overnight low at DLH warmer than the normal low temperature.
504 AM MST Fri Jan 19 2018 5 am update: Given continuing light precipitation across southern and eastern zones combined with ground temperatures hovering around freezing, icy road conditions are still expected in some areas this morning. While temperatures are above freezing over much of the area, ground temperatures are around freezing in many cases. The weekend ahead will feature a split trough moving over the region with the colder air from the northern stream affecting northeast Montana.
At the surface, a cold Arctic high pressure center is slowly moving eastward along the northern Gulf Coast. while freezing temperatures have been observed in areas north of Tampa Bay, residual low level moisture from earlier onshore flow remains near the coast, and dewpoints remain in the low to mid 30s in some areas well inland. With light northerly flow, some drying should occur through sunrise and will maintain existing freeze and hard freeze warnings, though actual freezing temperatures will likely be more spotty south of I-4. This should prevent temperatures from getting quite as low, but a few locations over the Nature Coast could still briefly fall to around freezing by early Saturday morning.
528 AM EST Fri Jan 19 2018 High pressure will maintain dry and warmer weather through Saturday. Intensifying warm advection under building upper high pressure in advance of a Cntrl Rockies-to-Plains low will drive Upper Ohio temperature well above the averages for the start of the new week.
1042 AM EST Fri Jan 19 2018 A large area of high pressure centered over the Lower Mississippi Valley will maintain fair skies for the next few days.
949 AM EST Fri Jan 19 2018 High pressure will move east through the southeast states this weekend.
Temperatures will continue to increase with highs in the low/mid 60s expected.
620 AM EST Fri Jan 19 2018 Arctic high pressure over the southeastern United States will slowly move south through Saturday. Clear skies were noted under the expansive, arctic high pressure centered over MS/AL this morning. The high extended northeast to cover all the mid-Atlantic states.
432 AM PST Fri Jan 19 2018 A weather system moving through the region today will bring areas of rain and mountain snow through early Saturday, along with cooler temperatures into the weekend.
At KBPT, ceilings may lower further after 20/08Z to near IFR, with some patchy fog and drizzle possible as the warm frontal boundary nears the terminal. Temperatures will continue to increase with highs in the low/mid 60s expected.
546 AM EST Fri Jan 19 2018 High pressure will prevail through the weekend.
High pressure over the southeast U. will bring warmer and dry weather through Saturday.
944 AM EST Fri Jan 19 2018 High pressure over the Lower Mississippi Valley will move east across the Gulf Coast states today and tonight.
740 AM PST Fri Jan 19 2018 A slightly cooler but still very moist maritime air mass will allow snow to return on area mountain passes and some minor accumulations in the valleys as well this weekend.
At the surface, light winds are expected today as the ridge center sits directly overhead.
But as the high pressure ridge continues to push east across north FL and into the Atlc, winds will decrease less than 10 knots and veer NE-E this afternoon.
Cloud cover will increase late tonight ahead of a developing warm front associated with an approaching low pressure system. Kanofsky Saturday-Saturday Night A deep progressive upper trof will advance through the southwest U. The mid Mississippi Valley Region during this time will be dominated by gradually backing west to west-southwest flow aloft, while the lower troposphere will feature a prominent low level WAA regime demarcated by southerly surface flow veering to southwest from around 2-5 kft.
a low pressure system will move inland through California and into Arizona bringing stronger onshore flow with cooling.
447 AM MST Fri Jan 19 2018 Current surface shows weak cold front across eastern Montana into northern Wyoming. Low level thermal ridge shifts east today as weak cold front slides through forecast area. Upper trof moving into western CONUS slides through the Rockies on Saturday, with cut off low developing over the four corners region.
609 AM EST Fri Jan 19 2018 A large area of high pressure will build east across the southern United States today and eventually move off the east coast.
630 AM CST Fri Jan 19 2018 For the 19/12Z terminal forecast will prevail VFR flight categories with ceilings from 4-5 KFT for most locations and expecting the low level moisture to be trapped underneath an inversion.
/issued 301 AM CST Fri Jan 19 2018/ Temperatures are in the low to middle 20s across most of the Midsouth, likely cooling another 2-4 degrees by sunrise. Temperatures will warm quickly, with moist of the region above freezing before midday. Temperatures will remain above freezing for several days. still a little below normal at most locations, but much warmer than we have endured for most of 2018. Clouds will return to the Midsouth tonight as a low latitude trough tracks along the Gulf Coast.
Maximum temperatures on Saturday are forecast to rise to the lower 70s, just shy of average for this time of year.
The cold upper trough moves onshore this afternoon, however, appears the best concentration of showers associated with the trough will move ashore to our south, so may need to reevaluate continuing the winter storm warning based on trends that develop later this morning.
1011 AM EST Fri Jan 19 2018 High pressure will prevail through the weekend.
520 AM EST Fri Jan 19 2018 Quiet aviation conditions continue across the region as high pressure remains in control. Terminals should remain in VFR conditions until late tonight when a warm front lifts through potentially opening the door for MVFR cigs to fill in.
951 AM EST Fri Jan 19 2018 A large area of high pressure centered over the Lower Mississippi Valley will maintain fair skies for the next few days.
1000 AM EST Fri Jan 19 2018 Arctic high pressure over the southeastern United States will slowly move south through Saturday. May cancel the winter weather advisory for black ice prior to 12 PM expiration as sfc temperatures warm well above freezing. While temperatures at the surface were in the lower 20s, at 300 ft AGL, temperatures were in the upper 30s. A minor s/w passing to our north and a weak area of high pressure to our south will maintain this wly flow through tonight. So while areas that have bare ground will see afternoon temperatures in the lower 50s, temperatures in the low-mid 40s will be common where widespread snow covers the ground. The snow melt regions should continue to struggle with highs in the lower 50s.
Saturday will continue to be cool and showery, particularly in the higher terrain.
653 AM EST Fri Jan 19 2018 High pressure centered over the Gulf Coast states will extend up into the region into the weekend.
524 AM EST Fri Jan 19 2018 With high pressure passing south of the area, a southwest flow will bring milder air through the weekend, with a warm front passing Saturday.
610 AM EST Fri Jan 19 2018 High pressure over the Lower Mississippi Valley will move east across the Gulf Coast states today and tonight.
1026 AM EST Fri Jan 19 2018 With high pressure passing south of the area, a southwest flow will bring milder air through the weekend, with a warm front passing Saturday.
535 AM CST Fri Jan 19 2018 Broad southwest flow leading to ample warm air advection this morning as high pressure continues sliding into the Deep South and pressure falls occur well off to our west. Despite what appears to be a strong subsidence inversion, gusty southwest winds may be able to mix some of this warmer air aloft down to the surface. Warm air advection expected to continue overnight with lows only expected to fall the lower to middle 30s, which should feel warm considering temperatures of recent weeks. , broad southerly flow will prevail across the lower and mid- Mississippi Vly with increasing moisture advection thanks to a wide open Gulf of Mexico.
905 AM EST Fri Jan 19 2018 Mid to upper level trough extends from the Mid Atlantic southwest to east central TX with only a few high cirrus pushing through the local area. 22 inches (indicative of arctic type air) and warm air aloft that is about 20 deg cooler than the sfc. No big change in the low temps for tonight/Saturday morning. Strong high pressure centered over the Gulf Coast region will continue to slowly move east the next couple of days.
300 AM EDT Sat Jun 24 2017 A trough of low pressure will remain across the Great Lakes today and tonight. Sunday a cold front will swing east across the region.
Upper air analysis last evening showed a broad, shallow trough over the country with the flow over Texas from the northwest. At the surface, a cold front was stretched from south of Dallas to San Angelo to Van Horn. The cold front will move into our CWA and stall.
The cold front that has left far milder air behind here in the Midwest has progressed to roughly the Appalachians this morning. High pressure is trying to build into the region. with the ridge oriented more NW/SE over the Plains. winds on this side of the developing ridge are more northwesterly and will continue that way through today. Cooler through the rest of the weekend.
Max temps today rather tricky given lingering cloud cover, though in general expect a warmer day area-wide with a few breaks in the overcast by afternoon, though temps will still be below average by late June standards.
A warm front will become established across Kansas, becoming a trigger for showers and thunderstorms.
553 AM EDT Sat Jun 24 2017 Showers will exit central Pennsylvania this morning as a cold front pushes eastward across the region. Drier and cooler air with comfortable humidity will arrive and last through much of the coming week. Afternoon highs should range from the mid 70s north to the lower to middle 80s southeast. Mins across the southeast will fall to the lower 60s. Highs will be several degress cooler throughout. Models have trended toward much better agreement with the evolution of the seasonably strong large scale upper trough over the Eastern U.
Cold front currently located across Middle TN will move into the area this morning. Model consensus is for this activity to push through the area by afternoon with high pressure building into the area this evening.
245 AM CDT Sat Jun 24 2017 243 AM CDT Early morning water vapor imagery shows a broad upper trough over much of North America with a large ridge along the west coast. Highs should top out in the low to mid 70s. A closer look at water vapor reveals several closed upper lows with focus being on one moving south-southeast out of southern Manitoba/Saskatchewan into North Dakota. MDB 243 AM CDT Even cooler 850 millibar air settles in for Sunday keeping highs a couple degrees cooler over those of today. The large scale upper trough will still be in place and there may be a greater coverage of stratocu.
446 AM EDT Sat Jun 24 2017 Cold front exits eastern mountains this morning. High pressure builds providing dry conditions.
324 AM CDT Sat Jun 24 2017 An upper level trough will track from the northern plains today into the Great Lakes tonight. At the sfc a cool/dry area of high pressure will slide down out of Canada and into the northern and central plains. As we get into the first days of the upcoming work week, the upper level ridge axis is starting to push east more into the Rockies, thanks to a stronger system moving into western Canada.
Additional showers and thunderstorms are developing along and behind a cold front which is currently moving into the Big Country. Much cooler temperatures and gusty northeast winds are expected behind the front. West Central Texas will be in northwest flow aloft, as an upper level ridge remain centered over Arizona/northern Mexico.
High pressure is locked on over much of the western states this morning. The axis of the ridge is currently along the coast with eastern Oregon and southwest Idaho under dry northwesterly flow. The ridge of high pressure is expected to slide eastward today and Sunday. As the ridge axis and its associated surface thermal trough approach temperatures will warm to above normal readings. Very limited mid/upper level moisture is forecast to swing northward along the thermal trough and may approach central Oregon by late Sunday.
Today will likely be the warmest of the two days as a weak front is expected to pass through the region tonight, yielding in even drier air and slightly cooler air for Sunday.
/Issued 914 PM CDT Fri Jun 23 2017/ Decided to extend the high risk of rip currents to 10z Saturday given the current sea state/wind.
