A weak cold front approaching the Southern Appalachian Region is expect it to stall over the general area late tonight.
757 PM EDT Sat Aug 12 2017 A cold front will approach from the northwest and settle into central NC overnight then stall. Scattered convection will continue to percolate across central NC into the evening hours as a weak mid level trough drifts east across the region. Convection will be more concentrated in the east vs west due to the proximity of the 850mb trough. however, should see an increase in convective coverage late this evening/overnight as a cold front approaches from the northwest. The sfc cold front will stall in vicinity of highway 64 as it becomes parallel to the flow aloft. Thereafter, guidance suggests central NC will be situated at the southern periphery of the westerlies, on the northern periphery of an upper level ridge progged to amplify over the Deep South.
744 PM EDT Sat Aug 12 2017 A few showers and thunderstorms will be possible this evening as a cold front moves through. Later tonight and Sunday, drier air will slowly build into the region, courtesy of incoming high pressure.
608 PM CDT Sat Aug 12 2017 High pressure over the area will slide east to the Great lakes by tonight.
Still unsure of coverage across the north as upper low drops through so maintain low pops later tonight.
1047 PM EDT Sat Aug 12 2017 A cold front moves through the area tonight followed by high pressure building in for Sunday and Sunday night.
Decks should lower possibly become MVFR around 09-12Z but keep things scattered out for now as forecast soundings and short term guidance are lacking moisture due to upper level ridging.

High pressure resulting in a great August weekend for outdoor activities. This Evening and Tonight Similar to last night, with high pressure over the Upper Midwest, lows are forecast in the lower to middle 50s on avg. However, there will be an upper low over Minnesota and cold front through NW Iowa. Uttech High pressure retreating to the east and the onset of warm advection will lead to a warming trend early in the week.
Dry air is advecting in from the north, with dew points in the lower 60s moving in across the I-64 corridor. A weak ridge of high pressure situated over the southern and eastern Great Lakes should settle over the region tonight and tomorrow and most of Sunday.

1028 PM EDT Sat Aug 12 2017 Skies are mostly clear with temperatures in the lower to mid 80s along the Florida Keys. Surface wise, a broad and diffuse ridge lies across extreme south Florida and the adjacent Atlantic and Gulf waters. Otherwise, our evening sounding reveals A ridge axis below 700 mb will nose into our region which will allow drier air to filter into our region.
No major changes were needed as building high pressure under weak upper troughing will suppress precip and support seasonable temperature. Any chance of rain during the beginning of the work week will be contained to locations south and east of Pittsburgh, primarily in the highest elevations.
/Issued 929 PM CDT Sat Aug 12 2017/ First round of convection has shifted to our east with additional convection having formed across south central Oklahoma and northern Texas near surface frontal boundary and ahead of approaching short wave trough.

/issued 310 PM CDT Sat Aug 12 2017/ Temperatures this afternoon ranging from the upper 80s across the I-30 corridor to the lower 90s across deep East Texas. Temperatures on Sunday to be much cooler across the ArklaTex with highs ranging from the mid 70s across to the Ozarks, the mid 80s across I-20, and lower 90s across deep east Texas and north Louisiana. Upper-level flow to become zonal on Sunday as ridge begins to flatten across northern Mexico.
735 PM EDT Sat Aug 12 2017 High pressure will extend across the area through the first half of the week.
Cold front is moving onshore in Washington and northern Oregon with some light precipitation as mid and high level clouds are already pushing east of the Cascades. The front is expected to bring some light precipitation across the forecast area as it moves through Sunday morning, followed by gusty winds and cooler temperatures.
1132 PM EDT Sat Aug 12 2017 A cold front and associated upper-level trough are moving through our region this evening. Cooler and drier air should replace the humid air mass. A weak trough will dominate our weather most of the week as a ridge builds over the southern US.
The upper low responsible for this activity continues to move east across North Dakota with drier air wrapping around into eastern Montana. Upper trough over the northern high plains may lead to some lingering thunderstorms over the eastern border counties late today into the evening. A few convective cells may also form over the higher terrain this evening. High pressure will build over the region for Sunday leading to warmer conditions. That looks short lived however, as an upper low centered over British Columbia exerts its influence and pushes a good deal of energy and associated cold front into the Pacific NW and northern Rockies.
High pressure will continue to ridge from the Atlantic into the eastern Gulf of Mexico, with light winds, and seas of no more than 2 feet.
/issued 337 PM CDT Sat Aug 12 2017/ Mid-level trough and an associated MCV were making steady progress across our Rolling Plains' counties this afternoon ahead of a distinct layer of subsidence. Barring some lingering showers off the Caprock early Sunday and a few afternoon storms near the NM state line, much of the day looks to be uneventful as transient upper ridging overspreads the area. This story should hold until Sunday evening when the next trough in westerly flow arrives from the Colorado Plateau.
927 PM EDT Sat Aug 12 2017 A cold front and associated upper-level trough are moving through our region this evening. Cooler and drier air should replace the humid air mass. A weak trough will dominate our weather most of the week as a ridge builds over the southern US.
A trough across the lake this evening with bring a few scattered showers to the central and east lakeshore counties this evening for just the next 2 or 3 hours.

Generally a zonal flow into North Dakota, with a weak/transitory mid level ridge over the region currently, which shifts east this evening. Across the south, the combination of less ice crystal production aloft, and a warmer low/mid level pocket of air at times, will result in a wintry mix of light freezing drizzle and snow, mainly along and south of Interstate 94 later Friday night through Saturday.
335 AM EDT Fri Nov 3 2017 A cold front will push through the area today. A cold front will push through the region today, providing some showers. A s/w trof will swing thru Saturday morning resulting scattered showers, most numerous across across the WV lowlands and mountains. A developing warm front across the region will keep the threat of showers through the afternoon but with much less coverage. The warm front lifts to the north Saturday night as southerly flow continues across the area, helping to keep lows on the warm side.
500 AM CDT Fri Nov 3 2017 Cloudy and warm area wide with low to mid 70s for most, but is a tad cooler NW sections with a weak cold front on approach. Otherwise, the next big cold front will arrive for mid to late week temperature wise.

353 AM CDT Fri Nov 3 2017 Surface cold front curves from Hugo to McAlester and then northeast to Sallisaw/Fort Smith. Some mid to late afternoon clearing should occur from the south, and locations south of Interstate 40 could be in the 70s while areas near the Kansas border will remain in the low to mid 50s. The front will lift north as a warm front on Saturday, and clouds north of the front will affect high temps again. Still, it should be much warmer on Sat/Sun than today with highs in the 70s to lower 80s.

424 AM EDT Fri Nov 3 2017 A cold front continues to steadily make headway south and east, currently laid out from the southeastern Great Lakes to the Missouri/Tennessee border. Given the northern extent of the core of the upper trough across lower Canada and the Great Lakes, still expecting the front to slow its southward progress and hang up in vicinity of the upper Tennessee Valley or southern Kentucky later this afternoon into this evening. Warm air advection will promote temperatures warming back into the low 70s underneath a good deal of lingering cloud cover.
Temps will only rise a few degrees during the day, with NE winds bringing cooler temps, but still above normal, on Friday night. Will start with a warm front lifting north through Kentucky and well into Indiana on Saturday, which will make for an unseasonably warm weekend.
early morning surface analysis had a 1023mb high centered over the Central Savannah River Area and ridging southwest across our southeast most zones. A nearly stationary cold front was also noted along the Ohio river extending southwest across northwest Arkansas and into central Texas. Otherwise, warmer than normal temperatures will continue topping out in the lower 80s despite the rain chances and cloud cover. Cloud cover tonight will help hold morning lows in the low to mid 60s.
1246 AM CDT Fri Nov 3 2017 Surface trof near the Canadian border is the focus for snow showers this evening. Highs will be in the low to middle 30s, with the warmest conditions in northwest Wisconsin.
H7 temps look to hover right around freezing for much of the day where this precipitation is expected to fall.
631 AM EDT Fri Nov 3 2017 Northwest winds around 10 knots continue in the wake of the cold front. Winds will begin to veer to the northeast through the afternoon as high pressure begins to drift across the Great Lakes. The mean position of the upper trough axis resides over western Canada/Pacific NW with subtle upper ridging positioned over over portions of the CONUS east of the Mississippi.
246 AM PDT Fri Nov 3 2017 As the low moves east and out of the region, the snow and precip will taper off through today.

High pressure situated across south cntl Ga will slowly weaken and drift southwest to across the Fl Panhandle through tonight. An inverted trough will continue to develop near the Bahamas and begin to move west towards the Fl peninsula. A few showers will be possible across the lower Ne Fl waters otherwise dry conditions expected with above normal temps in the lower to mid 80s inland and upper 70s along the coast. High-Res models continue to indicate the potential for fog and low clouds to develop mainly from the upper Suwannee Valley into Se Ga near the ridge axis.
The SW flank of an H100-H70 ridge axis extending from the Mid Atlc coast into the wrn GOMex will pinch off into an independent anticyclone as it is eroded from the NW by a large cyclone over the upr Midwest/Great Lakes. and from the SE by an inverted trof approaching the Bahamas. Once this happens, the newly formed anticyclone will retrograde into the GOMex, where it will retrench and block the inverted trof from advancing any further east than the the Bahama Bank. Position of the ridge will maintain a stout mid lvl subsidence inversion over central FL.
and Florida will continue today then some troughing develops along the southeast U. Temperatures will remain a few degrees above normal with daytime highs climbing into the lower to mid 80s and lows tonight in the upper 50s Nature Coast to lower and middle 60s elsewhere.
Expect KDHT to have some fog along with the low clouds to build in over the next few hours. A cold front has pushed into the area today which has held temperatures to the mid 50s across the Oklahoma Panhandles while temperatures have reached into the upper 70s across the southern Texas Panhandle. The cooler post-frontal airmass combined with light winds overnight are expected to result in low clouds and patchy fog across the area.
359 AM CDT Fri Nov 3 2017 Water vapor loop indicated a flat upper ridge over MT/WY. Ridge will move over the forecast area later this morning. An upper level trough over the Pacific Northwest will move into the Northern Plains on Sat. Cold front will sweep across the forecast area Sat afternoon and evening.
