706 PM EDT Tue Sep 13 2016 Quiet weather expected tonight with high pressure gradually moving east of the area. a cold front will quickly enter the region from the west on Wednesday and enhance the potential for showers across much of the area.
1212 AM EDT Wed Sep 14 2016 High pressure should maintain dry weather overnight before a crossing cold front returns scattered showers and thunderstorms to the region Wednesday. High pressure should maintain dry weather tonight as it slides east of the area. A cold front is progged for approach and passage Wednesday.
803 PM EDT TUE SEP 13 2016 High pressure will extend south into the area through Wednesday night.
Showers will continue through the night and spread into the Camas Prairie, as the upper low in Nevada moves to eastern Idaho Wednesday morning.
825 PM EDT TUE SEP 13 2016 An area of low pressure along the northeast Florida coast this evening was slowly lifting northward.
536 AM CST Thu Feb 16 2017 VFR through the next 24 hours with a weak upper level low pressure system approaching from the southwest moving to about 75 miles south of KCDS by 12z Friday. /issued 312 AM CST Thu Feb 16 2017/ An upper level low pressure system, currently edging east-southeast along the west coast of Mexico near Los Mochis, will punch northeast later today all the way to near Fort Davis, Texas. The upper low is fairly vigorous, as apparent by the tight spin and ongoing thunder activity over northwest Mexico at this time. RMcQueen The upper low currently over the Gulf of California will push east of the FA by later tomorrow. This low will bring with it a weak front.
551 AM EST Thu Feb 16 2017 High pressure will move across the area today providing fair weather with temperatures slightly warmer than yesterday. A warm front will move through the area late tonight and Friday morning, followed by much warmer temperatures Friday afternoon. /canada longwave trof. Convergence along a wk warm front movg into the area tonight may also cause some low clouds to form. Likewise, only 5-10F diurnal temp falls tonight as waa associated with incoming warm front strengthens and considerable cloudiness conts. Temps will warm into the 50s Friday as skies clear behind the warm front and upr ridge axis moves into IN.
558 AM EST Thu Feb 16 2017 A low pressure area off the New England coast will move east into Nova Scotia later today. A ridge of high pressure will build into the north country on Friday, with mainly partly sunny skies expected from Friday through the holiday weekend. Expecting snow to wind down this afternoon as the low pressure area moves into Nova Scotia later today. A weak ridge of high pressure will build east from the Great Lakes later tonight and will be over the north country on Friday, with mainly partly sunny skies expected and high temperatures mainly in the 20s. mid/upper level ridge builds overhead, resulting in benign weather.
454 AM CST Thu Feb 16 2017 Upper level ridging will be invoked over the Ozarks today as strong cyclonic flow persists over the northeastern United States and upper level low pressure slowly approaches southern Texas. Brisk and gusty southwest winds will develop at the surface with strong warm air advection commencing in the low levels of the atmosphere. We went on the high side of temperature guidance today with highs warming into the middle to upper 60s. We have therefore again gone warm with temperatures with lows ranging from the upper 30s over the eastern Ozarks to the lower and middle 40s over western Missouri and southeastern Kansas.
901 AM EST Thu Feb 16 2017 Some lingering clouds associated with a cold front that is now located over southern Florida are still being reported from Tampa Bay southward. Winds and seas will continue to subside Friday as high pressure builds into the area.
A continued gradual warming trend is expected through Friday as a closed low migrates over the region. Best moisture profiles will be located along the Texas Gulf Coast and as a result, will keep much of the region dry despite the low passing over. This will likely increase winds out west and lower min RH values into the low 20s or upper teens resulting in elevated and near-critical fire weather conditions on the plateau.
350 AM MST Thu Feb 16 2017 Upper ridge in combination with lee troffing across the plains will bring record to near record high temperatures today across the plains. Current grids either tie or come within a degree of these values today as sunny skies and deep mixing tap warmer air aloft. Elsewhere across the mountains and valleys, temperatures today will be similar to a degree or two warmer than yesterday. Southwest flow increases overnight and lee troffing across the plains should keep temperatures fairly warm along the lower eastern slopes/I-25 corridor.
733 AM EST Thu Feb 16 2017 A low pressure area off the New England coast will move east into Nova Scotia later today. A ridge of high pressure will build into the north country on Friday, with mainly partly sunny skies expected from Friday through the holiday weekend. Expecting snow to wind down this afternoon as the low pressure area moves into Nova Scotia later today. A weak ridge of high pressure will build east from the Great Lakes later tonight and will be over the north country on Friday, with mainly partly sunny skies expected and high temperatures mainly in the 20s. mid/upper level ridge builds overhead, resulting in benign weather.
451 AM CST Thu Feb 16 2017 Clear skies and near calm conditions observed this morning as high pressure at the surface is firmly in place just to our southwest. These readings may dip another degree or two by sunrise with many locations near or below freezing and some patchy frost, especially along and north of the I-30 corridor. Mid and high level clouds will also be increasing, especially after midnight as southwest flow aloft becomes increasingly influential with an advancing upper trough and closed low lifting north from Mexico across TX and the western Gulf coast. Despite the increased cloud cover and potential for rain, temperatures will run a few degrees warmer on Friday as southerly flow increases so expect highs in the upper 60s to lower 70s.
Therefore, a tempo group has been added to the east coast taf sites for this morning for the lower ceilings. Hazardous seas remain in wake of cold front. In its wake will be cooler temperatures, closer to seasonal averages compared to the warmer than average temperatures we have been experiencing the last few days.
803 AM EST Thu Feb 16 2017 Snow showers will taper off later today as high pressure builds in. The high should maintain mainly dry and warmer weather this weekend. Maintained the Winter Weather Advisory through 10AM for the ridges, though additional accumulations should be light. Broad area of high pressure will build in Friday, bringing much quieter weather for the weekend.
A weak cold front will push through the area tonight. As an upper trough moves through the area tonight, ascent will cause isolated to scattered showers to develop. Cooler air will filter in, but still expecting above seasonal highs with 850mb temperatures only falling to around 8c.
607 AM EST Thu Feb 16 2017 A deep upper level trough along the eastern seaboard will lift offshore into the Atlantic tonight. An upper level ridge over the Mississippi river valley will amplify as it builds eastward over the Carolinas Friday into Friday night. Clear skies and a breezy WNW wind (sustained ~15 mph with gusts up to 25 mph) are expected today in assoc/w synoptic subsidence on the western periphery of a powerful upper level low and attendant sfc cyclone lifting NE from New England into the Canadian Maritimes. Cold advection has deposited a cooler/drier airmass in central NC this morning.
As a result, temperatures and moisture will gradually increase through the short term, with temperatures today expected to reach into the upper 60s across the Northern Coastal Bend and into the lower 70s across the Brush Country.
Moisture levels will increase more significantly for Fri as an upper level closed low lifts NE into the region. rain chances do return to the forecast for Fri night as the upper closed low moves over AR.
Cloud cover should continue to inrease today with Pacific moisture on the backside of the ridge spreading across the divide.
Cloud cover should continue to increase today with Pacific moisture on the backside of the ridge spreading across the divide.
508 AM EST Thu Feb 16 2017 A weak cold front moved through the Florida Keys within the last few hours, with northwest winds prevailing most locations now.
950 AM EST Thu Feb 16 2017 Cold front will continue to move southeast through the Bahamas this afternoon with cooler and drier airmass in its wake. High temperatures will be about 10 degrees cooler than yesterday, around 70 from Leesburg to Daytona Beach to the mid 70s from Okeechobee county to the Treasure coast.
930 AM EST Thu Feb 16 2017 High pressure builds overhead through Friday.
936 AM EST Thu Feb 16 2017 Weak high pressure will briefly build into the area today. A warm front will lift through the region tonight into Friday, marking the beginning of very warm temperatures through the forecast period.

Mid/upper level ridging will take place through the MS/OH River Valleys during the next 24-48 hours.
High pressure is in control of the region's weather today and will bring pleasant conditions with high temperatures around 5 degrees above average for the date. This ridging surface and aloft will maintain dry weather through tonight and begin and warming trend. Under full insolation and a light wind, temperatures today will top out slightly warmer than normal. Strong radiational cooling tonight will send temperatures back into the 30s over the eastern half of Mississippi but weak waa in the west will hold temperatures slightly above normal in the lower 40s.
1001 AM EST Thu Feb 16 2017 Low pressure will pull away today leaving behind upslope snow showers in the mountains after snow ends this morning elsewhere. High pressure will build into the region on Friday as the storm departs to the maritimes.
Considering that this airmass is relatively warm, trapped cold air in valleys across northwest Montana will be favorable for patches of freezing rain to exist through late this morning.
937 AM EST Thu Feb 16 2017 A low pressure area off the New England coast will move east into Nova Scotia later today. A ridge of high pressure will build into the north country on Friday, with mainly partly sunny skies expected from Friday through the holiday weekend. Composite reflectivity showing ~25dbz bands across Chittenden county at 1430Z, and observational and model trends suggest an additional 1-2" possible, especially across nrn VT, with a bit more for the higher summits from Mt. A weak ridge of high pressure will build east from the Great Lakes later tonight and will be over the north country on Friday, with mainly partly sunny skies expected and high temperatures mainly in the 20s. mid/upper level ridge builds overhead, resulting in benign weather.
330 AM MST Thu Feb 16 2017 Upper level ridge and thermal ridge will shift east across the forecast area today. It's already very mild in/near the foothills with current temps in the lower to mid 50s, and with additional warming aloft, full sunshine, and weak downslope flow we should easily reach the lower 70s on all of the plains. A weak cold front moves across the plains after midnight, but this would do little more than keep temperatures up a few degrees due to increased mixing. Southwest flow aloft will prevail over the Central Rockies Friday ahead of an upper level trough approaching the southern California coast. Temperatures will be cooler Friday behind a cold front that will push through late Thursday night. Highs will still be well above normal Friday with highs in the lower to mid 60s across northeast Colorado.
Another mild day is expected as high pressure begins to break down. A weak low pressure system will brush the state today and light rain showers will slowly move across northern Nevada. A stronger low pressure system will bring substantial rainfall to areas south of highway 50 this weekend.
Temperatures are in the lower to mid 70s. In the low levels of the atmosphere, an area of high pressure will move eastward through the northern Gulf of Mexico this afternoon. In the mid levels of the atmosphere, a ridge of high pressure will be located over the western Gulf of Mexico today.
315 AM MST Thu Feb 16 2017 Upper ridge axis will move across the area today resulting in very warm and dry conditions. Cold front associated with the northern system will move across the local area Friday afternoon accompanied by breezy north winds, however temperatures will only be slightly cooler.
1011 AM EST Thu Feb 16 2017 High pressure will build across the southeastern states today through Friday.
High pressure aloft will shift east of the area today as the first in a series of weather disturbances reaches Utah tonight.
643 AM EST Thu Feb 16 2017 Low pressure will pull away today leaving behind upslope snow showers in the mountains after snow ends this morning elsewhere. High pressure will build into the region on Friday as the storm departs to the maritimes.
1000 AM EST Thu Feb 16 2017 A deep upper level trough along the eastern seaboard will lift offshore into the Atlantic tonight. An upper level ridge over the Mississippi river valley will amplify as it builds eastward over the Carolinas Friday into Friday night. Strong northwest flow will continue today on the back side of the departing upper trough, with strong height rises getting underway.
Breezy winds over the Gulf will continue to subside through the day, but the high risk of currents will continue at area beaches through early as waves and surf near the coast continue to slowly subside. Temperatures will be cooler and near seasonal normals today, with afternoon highs in the upper 60s and low to mid 70s.
1014 AM EST Thu Feb 16 2017 High pressure builds overhead through Friday.
912 AM CST Thu Feb 16 2017 Temps this morning ranged from the lower 30s down to the lower 20s in southern middle TN. The upper low over northern Mexico will move to the northeast, reaching central Texas by Friday morning. The upper ridge will amplify and push eastward and into the TN Valley by Friday afternoon. The warming trend will continue through the day and forecast highs will reach into the low to mid 60s Friday afternoon.
853 AM EST Thu Feb 16 2017 Low pressure will move across Nova Scotia today and into the Gulf of St Lawrence on Friday.
High pressure will then build in for the beginning of the weekend with drier and warmer conditions expected. A nearly stationary upper-level low pressure system is continuing to generate snow showers across the area this morning. Further lowering of the dendritic snow growth layer will continue to squeeze out high ratio snow, especially in the high terrain. Broad area of high pressure will build in Friday, bringing much quieter weather for the weekend.
522 AM CST Thu Feb 16 2017 At H5 Closed low over Northeast CONUS. Upper ridge has shifted east covering the western half of the CONUS and extending northeast to the Hudson Bay. Closed low off Pacific Northwest. Upper ridge with very warm air has moved east over all of western nebraska. Mostly sunny skies today with west to northwest down slope flow will have temperatures climbing into the low 70s over most areas. Southwest flow tonight will keep boundary layer mixed and hold temperatures in the lower 30s. High pressure due to high amplitude ridge across the western US will result in dry and warm conditions through the weekend.
As this air mass crosses the relatively warm waters of the Great Lakes, lake effect snow will impact central New York, with the highest snow amounts mainly north of Cortland, Norwich, and Cooperstown. Lake effect snow will diminish tonight, with high pressure building into the area on Friday, providing mainly dry weather through the weekend. High temperatures will range in the lower to middle 20s in central New York and upper 20s to lower 30s in northeast Pennsylvania. This period will complete the transition to a warmer and drier pattern. High pressure ridge will shift to New England Friday night, allowing significant warm air advection to begin via southwest flow on the backside of the ridge.
611 AM EST Thu Feb 16 2017 High pressure will build across the southeastern states today through Friday.
Morning surface analysis depicts high pressure (1022 millibars) centered over southeastern Texas. deep troughing prevails along the U. High pressure will migrate eastward along the northern Gulf coast this evening and will be centered near the FL/GA border in the Suwannee Valley at sunrise on Friday. Our local pressure gradient is only gradually loosening today as high pressure remains centered well to the west of our region.
620 AM EST Thu Feb 16 2017 Weak high pressure will briefly build into the area today. A warm front will lift through the region tonight into Friday, marking the beginning of very warm temperatures through the forecast period. Weak high pressure building into the TN and southern OH valleys will allow the beginning of increasing warm air advection in especially the SW forecast area. But the remainder of the region still under NW flow aloft and under the influence of the strong upper low beginning to pull off the NE coast. Big question will be just how long the clouds linger immediately behind the departing upper low.
645 AM EST Thu Feb 16 2017 Low pressure will move across Nova Scotia today and into the Gulf of St Lawrence on Friday.
403 AM MST Thu Feb 16 2017 Upper ridge axis will move across the area today resulting in very warm and dry conditions. Cold front associated with the northern system will move across the local area Friday afternoon accompanied by breezy north winds, however temperatures will only be slightly cooler.
1003 AM EST Thu Feb 16 2017 Snow showers will taper off through the afternoon as high pressure builds in. The high should maintain mainly dry and warmer weather this weekend. Broad area of high pressure will build in Friday, bringing much quieter weather for the weekend.
253 PM EDT SUN JUN 12 2016 Cold front continues southward push.
An area of low pressure currently over northwest SD will lift northward and track across North Dakota today. A trailing cold front will slide across this CWA today and will become the focal point for convection. A tornado threat is possible in far NE SD or near the triple point and along the warm front extending into MN.
123 PM PDT SUN JUN 12 2016 Low pressure off the coast will move inland tonight and weaken through Monday.
and Monday High pressure will provide a dry pleasant day across the western Great Lakes today behind a departing cold front.
357 PM EDT SUN JUN 12 2016 Weather tonight will be quiet as high pressure settles into the region. It will be cooler tonight with lows in the low to mid 50s.
We remain in northwest flow for most of the coming week as a strong ridge builds over central North America. Strong gusty winds, close to advisory category just downwind of the higher terrain are the issue this afternoon. No significant issues with high pressure in dry air mass. A tad warmer than Sunday.
228 PM CDT SUN JUN 12 2016 Upper level ridging was slowly building in from the west in advance of a storm system moving into Nevada and California. Overall instability levels are down a notch from yesterday and convective inhibition is up a bit from yesterday at this time while deep layer shear remains on the low side, but if storms are able to mature, there remains enough energy to support a brief strong to marginally severe storm. After another mild night tonight with lows ranging from the mid-60s to lower 70s, the building upper ridge will provide even hotter temperature tomorrow with highs in the mid-upper 90s common.
In the large scale, an upper trough moves through the Great Basin tonight then through this forecast area Monday afternoon-overnight. Monday night, thundershowers continue through the evening within the trough and cold advection aloft.
Scattered showers and storms developed this afternoon just ahead of a weak upper low. Short range models continue to advect a weak upper low eastward into the Ozarks tonight into Monday. and a second more potent upper low from srn CA into the Central Plains Tuesdsay.
models agree weak mid-upr level ridging will build into the region from the SW with H5 heights modestly rising to around 591 DM. Will also continue to show highs a degree to two above yesterdays values given influence of the ridge. SRLY low level jet increasing to 30-35 kts and bulk shear values bear 30 kts across the area combined with NNW corfidi vectors and favorable position of the H85-h7 theta-e ridge axis across this area suggest this is certainly a possibility. MLCAPE values of 1500+ J/kg in a marginal but directionally sheared environment would promote some storm organization, especially in NW sections of the Panhandles, where coverage is also likely to be the highest.
624 PM EDT SUN JUN 12 2016 A weak cold front will move through the region tonight and early Monday. Overnight lows expected in the lower to mid 70s under mostly clear skies. A secondary cold front/trough will move into or through the area Monday morning. The GFS is more aggressive driving slightly cooler/drier air south of the region than NAM. and this is reflected in the cooler MAV guidance. Weak downslope early and warm advection/upper level ridge/mos cool bias suggest temperatures will only be a little cooler. So continued forecast maximum temperatures in the low to mid 90s as surface winds shift to east.
with light northwest to north winds over the Lower Keys and adjacent waters and a seabreeze producing light east winds over Key Largo. The far western extent of troughing over the western Atlantic is sliding southward.
The only changes made were to increase temperatures along the coast, particularly near brookings, as models are showing easterly winds and the Chetco effect lingering well into the afternoon as the thermal trough sets up near the coast today.
409 PM EDT SUN JUN 12 2016 A dry cold front will continue to shift south over the area through the rest of the afternoon. High pressure will build over the area through Monday.
316 PM EDT SUN JUN 12 2016 A cold front is currently pushing through the area this afternoon and will bring drier and cooler air in its wake. High pressure will build south into the region tonight. The high will remain over the area on Monday. Warm and more humid conditions will return by mid week as the high moves east, allowing a weather system to approach from the west. A cold front is currently pushing through Wilmington with drier and cooler air slowly working its way south behind the front. Have gone slightly higher than this across the southwest and slightly cooler than this across the northeast.
A cooler and somewhat drier airmass has moved into the forecast area today behind yesterdays hot and somewhat humid conditions across the eastern half of the state. Dewpoints have been dropping this afternoon with most areas in the lower 40s.
326 PM EDT SUN JUN 12 2016 High pressure in control across the region. with hot conditions once again with 19z readings in the lower 90s in most areas. a very weak front is pushing south from the highlands/coal fields of WV and KY into SW VA and NE TN by this evening. along with some cooler highs for far NE TN and SW VA. Strong upper ridge of high pressure will continue to control area weather early in the extended.
the Tri State region is seeing yet another overnight period of above normal temperatures which are currently ranging in the lower to mid 70s.
Interior parts of the Thumb may be just a bit cooler than that, while the heat island of interior Metro Detroit may help keep low temperatures in the low 50s. Still, the dry low level air that has been ushered into the area with this high will limit shower and thunderstorm potential as this trough works into the area.
