1255 PM EST Sun Jan 15 2017 Other than some flurries this morning over parts of central New York, it will be dry and seasonably cold through Monday, with high pressure building across the region.
Ridge will gradually shift east into the Mid Atlantic waters into Monday shifting east winds towards the southeast during the day Monday. 0 inch is noted on the sounding but mainly below 950MB with a moderate east flow in the lower levels.
As for precip type, upstream observations show a brief period of freezing rain and at both the Imperial & Yuma Colorado observing sites. KSNY BUFKIT sounding supports at least the potential of a short period of freezing rain this evening.
131 PM EST Sun Jan 15 2017 High pressure will build into the area bringing clearing skies for Monday.
253 PM EST Sun Jan 15 2017 A frontal boundary will remain well south of the local area the into Monday as high pressure builds across New England. A series of weak low pressure systems will track along that boundary resulting in periods of unsettled weather through early in the upcoming week. but w/ the region E of the ridge axis (invof TN/OH valleys). Highs Mon in the low-mid 40s NNW to around 50 F far SE. lifting a warm front N of the local area.
In the middle and upper levels, (700-200 mb), latest available IR imagery as of 200 pm overlaid with model streamline analysis, depict a stretching negatively tilted middle and upper level trough across the Western CONUS, with its axis from the Great Salt Lake to West Texas. Downstream of that, middle and upper level flow flattens a bit with low amplitude anticyclonic ridging across the Eastern United States and the Western Caribbean, as well as South Florida and the Florida Keys. At the surface and in the lower to middle levels, latest available marine and land surface observations and analysis details the center of a 1030 mb cold anticyclone near Washington D.
1253 PM CST Sun Jan 15 2017 The freezing line and most of the precipitation has shifted to the north of the Ozarks this afternoon removing the threat of freezing rain from the Ozarks. The deep trough across the desert southwest and into old Mexico is expected by the models to cut off and linger nearly in place through the middle part of the week.
1212 PM EST Sun Jan 15 2017 High pressure will build across the area today.
216 PM CST Sun Jan 15 2017 (Tonight and Tomorrow) The upper low has moved from northern Mexico to far West Texas this afternoon with convective activity ongoing from the eastern Big Bend region north through the Permian Basin and then into the southern Panhandle. Overnight lows tonight will be in the lower 40s across all of the forecast area and highs tomorrow will range from around 60 in the Big Country to the lower 70s south of Interstate 10. 15 (Monday night through next Sunday) By Monday night, models continue to indicate a cut off upper level low developing over Mexico to our southwest.
1021 AM MST Sun Jan 15 2017 09z surface analysis had high over the Great Lakes with weak return flow over the CWA ahead of lee trough in place from central MT into central CO. Lift ahead of upper low will bring small chances for a wintry mix over south central SD late tonight. Upper low swings into the Midwest with lingering -SN ending over south central SD early. However, well-mixed boundary layer over northwest SD may actually allow higher temperatures behind the cold front compared to today. Ridging will help to bring above average temperatures across the CWA by midweek.
Freezing Rain Advisory until 6 PM CST this evening for OKZ016>018-022-034.
1054 AM MST Sun Jan 15 2017 18Z TAF CYCLE Widespread significant impacts to aviation continue as rain, snow, fog, and freezing rain shift across NM. Any area that clears before sunrise will likely see fog and freezing fog.
326 PM CST Sun Jan 15 2017 Area of rain and freezing rain is currently moving through northeast and north central KS. Where temperatures are above freezing the rain has pretty much come to an end besides some drizzle and maybe an isolated shower. Where temperatures are below freezing minor ice accumulation is taking place, but the ice:liquid ratios are fairly low. The only exception would be far north central KS where temperatures hover around freezing through tomorrow morning. As the precipitation type turns over to rain for most locations tonight the main upper level low pressure lifts over the area. As the upper low tracks overhead a dry slot moves in from the southwest tomorrow afternoon.
312 PM EST Sun Jan 15 2017 High pressure will build across the region tonight and move east Monday. Low pressure will track north of the region Monday with a weak cold front crossing the area Monday night.
449 PM EST Sun Jan 15 2017 A warm front will push northward tonight into Monday.
The upper pattern this evening is rather quiet and defined by an upper low over the Upper Midwest, a weak trough in the Eastern Pacific (off the California coast) and generally zonal flow across Southeast Arizona. The trough in the eastern Pacific will eventually make its way into southeast Arizona Tuesday and Tuesday night. Although this system is dry, it will bring some southwest breezes with a few gusts to 25 mph over the the higher peaks of SE Arizona Tuesday afternoon and Tuesday night.
1038 PM MDT Mon Apr 10 2017 The upper low has moved over northeastern NE/southeastern SD, and high pressure is moving into the Dakotas. Winds will become southerly tonight as high pressure slides to the east. A weak ridge will move over the northern plains Tuesday, bringing mild and dry weather. Generally dry and milder conditions will develop for the rest of the week as a weak ridging pattern remains over the region.
856 PM CDT Mon Apr 10 2017 Cold front this evening now extends from northwest Arkansas to far southeast Oklahoma.
630 PM CDT Mon Apr 10 2017 An upper system and cold front will move through AR this evening and overnight. Winds ahead of the front will be south to southwest at 5 to 15 mph, then switch to west to northwest behind the cold front and be 5 to 15 mph with some gusts.
The strongest storms area just ahead of the surface wave, just north of the warm front. The effective shear has increased to near 60 knots near and south of the warm front so the storms near the front will have to be watched.
956 PM EDT Mon Apr 10 2017 A weak cold front will cross east through the Ohio Valley tonight and early Tuesday.
1007 PM EDT Mon Apr 10 2017 High pressure remains centered off the Mid Atlantic coast through mid week.
High pressure east of the Mid Atlantic coast will remain in place through the weekend.
732 PM EDT Mon Apr 10 2017 A high pressure system will slowly give way to an approaching frontal system Tuesday. A weak cold front moves through Tuesday night. High pressure for mid week. Models agree on slowing the cold front from the west somewhat on Tuesday, even though the GFS is still the fastest.
813 PM EDT Mon Apr 10 2017 Surface wise we remain under the control of an area of high pressure to the east, however a cold front is moving into the Midwest this evening. The aforementioned cold front will be slow to progress east and the CAMs really have much of the upstream convection waning through the night into the dawn hours. Forecast concerns will shift from fire weather issues this afternoon to a threat for showers and a few thunderstorms by tomorrow afternoon as a weakening cold front passes into and across the region. Western valleys and ridges should stay mixed, however, with temps remaining in the 50s to around 60.
Low stratus/stratocumulus rotated around an H500 low over NE Nebraska and NW Iowa this afternoon, spilling across the KS/NE border late this morning along with a secondary cold front. This low will quickly shift eastward as a more zonal flow pattern sets in aloft with surface ridging pushing south from the Dakotas. With clouds clearing tonight and the ridge axis centered across Kansas, the stage is set for temperatures to fall into the low to mid 30s across much of the CWA.
851 PM EDT Mon Apr 10 2017 Sprawling high pressure will provide warm conditions through Tuesday.
Therefore, the cold front should linger across the southern zones for much of the overnight hours. As of 00Z, the cold front had just cleared all the Metroplex TAF sites. /ISSUED 319 PM CDT Mon Apr 10 2017/ Convection continues to develop along and ahead of a slow moving cold front which was near a line from Paris to Dallas to Goldthwaite at 3 PM. The atmosphere is quite unstable and severe thunderstorms will likely continue into the mid evening hours with storms slowly shifting southward with the cold front. The presence of the ridge will be very temporary due to the development of a strong trough across the western states.
1205 AM EDT Tue Apr 11 2017 High pressure that brought sunshine and warm temperatures Monday will move off the coast Tuesday.
835 PM EDT Mon Apr 10 2017 High pressure will persist near Bermuda through Tuesday night.
A cold front extending from near Dallas southwest across central Texas is producing a large area of strong thunderstorms. GOES-R imagery suggests some erosion of this lower cloud layer, so will indicate scattering into VFR but continue to monitor trends. /issued 425 PM CDT Mon Apr 10 2017/ The region remains between high pres off the eastern seaboard and a cold front/lower pres acrs OK into north TX, and this is maintaining breezy southerly winds acrs southeast TX and southwest LA. Aloft, the upper ridge axis has shifted east with winds bcmg more southwesterly in advance of a low amplitude trough over the southern plains.
The cold front is just now moving south of our counties. A cold front will stall along or just south of our Interstate 10 corridor tonight. /issued 307 PM CDT Mon Apr 10 2017/ (Tonight and Tuesday) A cold front is moving south through the forecast area. The cold front will slow down as it moves southeast through the forecast area and there is a chance for heavy rain in San Saba, Mason and Kimble counties this evening and overnight. Expect cooler temperatures on Tuesday with lows near 50 degrees in the Big Country to near 60 from Ozona to Junction. High temperatures on Tuesday will be in the low to mid 70s with some cloudiness lingering.
High pressure to our north, with its ridge axis oriented across the deep south into the western Atlantic, will maintain onshore flow across the region tonight. Afternoon forecast remains on track, where highlights for tonight include: a) warmer temperatures along the coast, especially from the Cape south, due to elevated boundary layer flow around 15 knots and b) potential for settling of smoke across the interior, especially near larger smoldering burns, that could once again lead to significant visibility reductions and road closures. A moderate to fresh easterly breeze will continue across the waters as high pressure ridge remains north of the area.
728 PM EDT Mon Apr 10 2017 A cold front will pass through the region Tuesday, with scattered showers and thunderstorms, especially in the afternoon to evening.
Dry and cooler weather is expected tonight across much of Oklahoma and western north Texas.
/ISSUED 1022 PM CDT Mon Apr 10 2017/ A challenging forecast continues to unfold for Southeast Texas this evening with surface analysis showing a nearly stationary cold front draped north and west of the region (roughly along a Dryden- Lampasas- Mount Pleasant line).
GOES-R imagery suggests some erosion of this lower cloud layer, so will indicate scattering into VFR but continue to monitor trends. /issued 425 PM CDT Mon Apr 10 2017/ The region remains between high pres off the eastern seaboard and a cold front/lower pres acrs OK into north TX, and this is maintaining breezy southerly winds acrs southeast TX and southwest LA. Aloft, the upper ridge axis has shifted east with winds bcmg more southwesterly in advance of a low amplitude trough over the southern plains.
/Issued 856 PM CDT Mon Apr 10 2017/ Cold front this evening now extends from northwest Arkansas to far southeast Oklahoma.
A cold front will then move into the region late in the week bringing increasing winds to Utah and a chance of precipitation across the northern portion of the state.
The cold front is currently moving southeast across the CWA and will move east of the CWA by 06Z. Temperatures will be cooler tonight with cold air advection behind the front.
A few high clouds are expected to move over our area, but dry conditions will prevail as we remain on the southwestern flank of high pressure at the surface, and under an upper level ridge.
Scattered showers and thunderstorms have shifted east of the forecast area moving with the sfc cold front. Temps and dewpoints will be falling behind a cold front through tonight.
940 PM EDT Mon Apr 10 2017 Low pressure over the Central Lakes will track across the Eastern Lakes Tuesday. The trailing cold front will push across the forecast area Tuesday morning.
938 PM EDT Mon Apr 10 2017 High pressure will linger over the western Atlantic through midweek.
With overnight temperatures dropping into the lower 30s, even a few flurries are also possible. BMickelson Previous short term discussion: Broad upper trough over western Canada is providing a SW flow over Montana this afternoon. Rainshowers associated with a mid- level trough will develop over central Montana later today and diminish as they move northeast into the CWA late this evening and overnight. Winds will increase behind the clouds/possible showers/mid-level trough Tuesday with speeds of 15-30 mph. Temperatures should be warmer as mixing and downslope flow will allow the mercury to reach the mid to upper 50s.
911 PM EDT Mon Apr 10 2017 Bermuda high pressure will extend west into the Carolinas until a cold front settles through the region late Wed and Wed night. WV satellite imagery and 00Z upper air data depict a short wavelength trough centered in the 200-400 mb layer, moving with a preceding band of cirrus, east across NC and VA this evening. Deep layer longwave ridging will otherwise continue to extend across the eastern U. tonight, with associated underlying 1028 mb high pressure centered near Bermuda. Alternating periods of calm and light southerly stirring around the ridge should favor lows in the upper 40s to lower 50s. Mid/Upper level ridging lingering over the Eastern Seaboard will shift offshore late in the day with continued southerly return flow around the offshore Bermuda high cell.
739 PM EDT Mon Apr 10 2017 Bermuda high pressure will extend west into the Carolinas until a cold front settles through the region late Wed and Wed night. Bermuda high pressure and ridging aloft will hang on over the region tonight with low-level southerly flow resulting in further airmass modification. Lows tonight a good 5 to 8 degrees warmer than last night. Lows in the lower to mid 50s. Tuesday and Tuesday night: Mid/Upper level ridging lingering over the Eastern Seaboard will shift offshore late in the day with continued southerly return flow around the offshore Bermuda high cell.
1111 PM CDT Mon Apr 10 2017 A rather vigorous upper level low was located over eastern SD this afternoon. A strong PV anomaly was seen at the base of the trough over northeast NE and northwest IA. This goes along well with the rather bumpy nature to the cloud tops seen in visible satellite imagery along with some of the higher dBZ echoes seen on radar. Therefore, cut low for these areas into the middle 20s with around 30 to the lower 30s heading east and south. A much better day weather-wise on Tuesday as high pressure builds in from the northern Plains.
Even with the high clouds temperatures splits of 14 degrees or more are common under this dry regime. Surface wise we remain under the control of an area of high pressure to the east, however a cold front is moving into the Midwest this evening. The aforementioned cold front will be slow to progress east and the CAMs really have much of the upstream convection waning through the night into the dawn hours. Forecast concerns will shift from fire weather issues this afternoon to a threat for showers and a few thunderstorms by tomorrow afternoon as a weakening cold front passes into and across the region. Western valleys and ridges should stay mixed, however, with temps remaining in the 50s to around 60.
452 PM PDT Mon Apr 10 2017 A few weak disturbances will bring cooler temperatures.
839 PM EDT Mon Apr 10 2017 Warm and breezy conditions will continue this evening with increasing chances for showers and thunderstorms as a cold front approaches.
with cooler temperatures and thunderstorms erupting just southeast of the forecast area. Short wave trough in low amplitude flow will work across Iowa and exit area early Tuesday. Cooler than normal highs on tap as well, especially with any snow cover in north central Wisconsin. Mean upper flow actually begins to build into a ridge overtime, but short waves moving through flow will bring precipitation threats every other day or so.
/issued 346 PM CDT Mon Apr 10 2017/ Satellite imagery and surface observations around 2:30 pm show that this morning's cold front is nearing I-10 in southwest Texas with the pressure gradient and northeasterly breezes gradually relaxing across our forecast area.
625 PM CDT Mon Apr 10 2017 A rather vigorous upper level low was located over eastern SD this afternoon. A strong PV anomaly was seen at the base of the trough over northeast NE and northwest IA. This goes along well with the rather bumpy nature to the cloud tops seen in visible satellite imagery along with some of the higher dBZ echoes seen on radar. Therefore, cut low for these areas into the middle 20s with around 30 to the lower 30s heading east and south.

926 PM EDT Mon Apr 10 2017 High pressure ridge axis will remain North of the region from the Wrn Atlc into the Carolinas and this will keep an Easterly flow in place through Tuesday. Max temps in the lower 80s inland and mid/upper 70s along the coast.
711 PM EDT Mon Apr 10 2017 High pressure will linger over the western Atlantic through midweek.
1137 PM CDT Mon Apr 10 2017 With lows tonight likely dropping below freezing over the southwestern CWA. increasing DPVA induces surface cyclogenesis in eastern CO with attendant warm front quickly lifting northward.
912 PM MST Mon Apr 10 2017 Strengthening high pressure aloft will bring warming temperatures into the middle part of this week as well as very dry conditions. Lighter winds and warmer temperatures are then likely to return for the upcoming weekend as high pressure once again reestablishes itself over the region.
632 PM CDT Mon Apr 10 2017 With lows tonight likely dropping below freezing over the southwestern CWA. increasing DPVA induces surface cyclogenesis in eastern CO with attendant warm front quickly lifting northward.
920 PM EDT Mon Apr 10 2017 High pressure should maintain dry weather tonight. Scattered showers and possible thunderstorms are expected Tuesday with a weak crossing cold front. A weak cold front will approach the upper Ohio Valley on Tuesday. Low pressure associated with front will lift northeastward over Great Lakes, taking much of the deeper large scale lift with it. Overall, instability looks rather meager with plenty of cloud cover, hence the low confidence in thunder, save for maybe the southeastern zones.
722 PM EDT Mon Apr 10 2017 High pressure ridging into the forecast area from the Atlantic will dominate through Tuesday.
519 PM MDT Mon Apr 10 2017 The upper low has moved over northeastern NE/southeastern SD, and high pressure is moving into the Dakotas. Winds will become southerly tonight as high pressure slides to the east. A weak ridge will move over the northern plains Tuesday, bringing mild and dry weather.
