250 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.
Slow eastward progressing cold front stretches from just west of Chicago to Dallas and El Paso this afternoon.
Tranquil weather will continue across the region through tonight as deep layer ridging continues to dominate the tri-state region.
A cold front will bring showers and thunderstorms to the area tonight. Cold front still projected to move across area during the overnight so threat for showers will be continued through the overnight hours along with an isolated storm still possible.
Upwards of 2 to 4 inches of snow from Chamberlain to Mitchell this morning, with intermittent rain/sleet/snow/freezing rain across remaining areas and upwards of a tenth of an inch of ice north and northeast of Sioux Falls. Should skies clear sufficiently, may see a sharp drop into the lower 20s. Another tricky temperature forecast for Tuesday, as models are consistent in bringing a warm front northward. NAM stalls this front over the southeastern CWA, while other models try to pull warmer air slightly further north.
1133 AM MDT Mon Apr 10 2017 Valley temperatures have dropped below freezing at several of the lower valleys sites impacted by the freeze warning this morning.
The low level moisture tongue to our west resulted in some areas of morning cloudiness over MS, and I suspect the same tonight will edge into northwest AL by morning.
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.
Will see a late afternoon maximum in the low 40s as winds continue to weaken. Low level clouds continue to erode and with high pressure continuing to build in should see plenty of solar today. Clouds and warmer column should hold minimum temperatures in the low/mid 30s.
325 PM CDT Mon Apr 10 2017 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.
232 PM EDT Mon Apr 10 2017 High pressure remains centered off the Mid Atlantic coast through mid week.
The cold front has pushed south of all TAF sites, with gusty north winds persisting through the mid to late afternoon, before relaxing and shifting out of the north and northeast this evening. Cold front picking up southward momentum late this morning and is close to clearing rest of OUN CWA.
Other than being responsible for the weak cold front and a few storms overnight --and current way to our east--, this trough will provide little future impact in our area besides helping bring the breezy winds to the region today.
Models bring a modest cold front and associated disturbance through eastern Montana this evening.
High pressure ridge north of the area will maintain an elevated low level onshore flow across the region. Farther north and inland, east-northeast winds will decrease to around 5 mph late tonight with lows generally in the low 60s. Highs will again reach the upper 70s to around 80 degrees along the coast and in the low 80s across the interior.
412 PM CDT Mon Apr 10 2017 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.
An upper level area of high pressure will be over the region through the first half of the week resulting in a warming trend. 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.
326 PM EDT Mon Apr 10 2017 High pressure will remain anchored northeast of the area with onshore flow persisting. Weak trough offshore will bring some low clouds onshore tonight but partly cloudy skies should suffice.
At the time of this writing a cold front extended southwestward from south central WI across Missouri into north central Texas. In the wake of the front high pressure will keep the region dry with cooler temperatures. At the beginning of the period, upper level high pressure will be situated over the southeastern TX coast up into Louisiana and then sprawled out across the deep south. In the meantime, the upper level ridge will tend to strengthen over our area.
Much advertised cold front currently across portions of NE OK into NC TX will continue moving slowly south and east this afternoon through tonight approaching the I-30 Corridor in the 03-06z timeframe. Vigorous convection is expected to develop along this boundary later this afternoon just to our west with the convection likely developing in advance of the cold front, affecting the TYR/GGG/TXK and LFK terminals near or before 03z this evening and likely influencing the SHV/ELD terminals near or just beyond 03z as well. The front will stall to our northwest overnight tonight as a prefrontal trough will become the dominant feature overnight allowing the convection to spread eastward. /issued 1200 PM CDT Mon Apr 10 2017/ Cold front remains west of our region this morning near DFW metro area trailing back southwest across west central TX.
Warmer today with bigger jump in afternoon temperatures on Tuesday then holding relatively steady for the remainder of the week.
121 PM EDT Mon Apr 10 2017 Warm and breezy conditions will continue today with increasing chances for showers and thunderstorms this afternoon and evening as a cold front approaches.
150 PM EDT Mon Apr 10 2017 Sprawling high pressure will provide warm conditions through Tuesday.
315 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.
207 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. This will allow for a continuation of dry weather, with some thin cirrus overspilling the ridge.
258 PM EDT Mon Apr 10 2017 A weak cold front will bring the risk for showers or a storm Tuesday and Tuesday night. Warm advection in southerly flow, on the western edge of a departing upper ridge, will maintain seasonably warm and dry conditions through the near term. 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.
Some areas have gusted to 30 mph, but winds will continue a gradual downward trend into the evening hours as a cold front moves slowly south and east into the region. Rain chances will favor the northwest half of the CWA through 12z given the proximity to the cold front. This cold front will continue to move slowly south and east on Tuesday.
224 PM CDT Mon Apr 10 2017 A weak cold front has moved into the Permian Basin today and according to latest visible satellite and surface observations is currently sitting along a line from Big Lake, to McCamey, to Pecos. Cooler and drier air behind the front will keep any convective development this afternoon confined south of the front in the lower Trans Pecos and Big Bend.
327 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.
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.
649 PM EDT Mon Apr 10 2017 A trough of low pressure will move toward the region tonight and Tuesday.
356 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.
229 PM EDT Mon Apr 10 2017 High pressure remains centered off the Mid Atlantic coast through mid week.
Cold front currently moving through the area has resulted in a wind shift to the w-nw at the ne ok sites. /Issued 1039 AM CDT Mon Apr 10 2017/ Cold front continues to work its way across far sections of eastern Oklahoma this morning.
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.
High pressure continues into Tuesday and Tuesday night with dry conditions prevailing. Warmer temperatures return on Tuesday with highs ranging from the low 60s across the north to the low 70s south of I-80. High pressure continues into Tuesday night.
A cold front will bring showers and thunderstorms to the area tonight. After 00Z, expect scattered convection to continue to develop ahead of a cold front. Otherwise PoPs will diminish from northwest to southeast during the overnight as the cold front moves through.
12Z guidance has come in cooler with lows for Tuesday morning. The high will build over the area with winds weakening through the night. Have used the cooler side of model solutions with lows around freezing by Hays to middle 30s for Dodge and upper 30s along the Oklahoma border.
659 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.
112 PM EDT Mon Apr 10 2017 High pressure ridging into the forecast area from the Atlantic will dominate through Tuesday.
312 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.
Lower pressure over Lake Michigan and a cold front extending southeast into the Southern Plains was slowly moving east this afternoon. Weak southerly flow will continue tonight so lows will mostly in the 50s except the normal cooler spots in northeast Tennessee and southwest North Carolina. A weak cold front will shift east into the region Tuesday night, though it will likely bring a few isolated to spotty showers as models indicate a strong weakening trend with this activity.
226 PM CDT Mon Apr 10 2017 Cold front, currently located near a Fayetteville/Sallisaw/Daisy line, continues to push south this afternoon.
Convection having some difficulty remaining strong/severe as they shift northeast over the cooler and more stable airmass behind pneumonia front. Not sure how much severe convection will develop, with colder northeast winds undercutting the lowest 100 mb mean layer air parcels.
415 PM CDT Mon Apr 10 2017 A quiet morning has quickly transitioned into an active afternoon with increasingly unstable conditions expanding eastward ahead of a cold front advancing across east central Texas and beginning to near our northeast Texas zones along I-30 and north into southeast Oklahoma.
326 PM EDT Mon Apr 10 2017 High pressure will linger over the western Atlantic through midweek.
145 PM PDT Mon Apr 10 2017 A weak trough aloft will deepen the marine tonight and bring minor cooling to coastal and valley areas Tuesday.
227 PM EDT Mon Apr 10 2017 High pressure remains centered off the Mid Atlantic coast through mid week.
246 PM EDT Mon Apr 10 2017 Short term largely quiet with weakening high pressure over the area. Southerly flow ahead of a cold front moving into the state late in the period will draw additional moisture into the area. /issued 1254 PM EDT Mon Apr 10 2017/ A weak cold front moves into n GA Tuesday night with mainly small chances for showers over n GA as instability is limited.
1217 PM CDT Mon Apr 10 2017 In the near term, the main focus will be the potential for continued shower/thunderstorm activity along and just behind a southeastward moving cold front. A few isolated showers and storms will remain possible along the front especially east of Highway 65 over the next few hours, then will end as the cold front settles south of the region. Cooler temperatures and drier air will gradually sink into the region, but as the parent upper low lifts northeastward today, the coldest air will deliver only a glancing blow to our north- western CWA, and temperatures may still reach the low to even mid 70s south of the Missouri River where winds will be more westerly and cold-air advection will be weak.
/ISSUED 1146 AM CDT Mon Apr 10 2017/ Trends with surface data from 14-16Z show a cold front pushing into north Texas with radar imagery showing a few scattered showers around SE Texas. Aloft upper air analysis shows jet streak coming across the southern Plains with the main upper level low over the northern Plains. Trough axis lags back south with this low but area of height falls are well to the north. Inflow will be normal to the front and convective lines so "if" the low level jet can increase overnight with mesoscale influences, then storms may be able to achieve some higher rain rates with slow storm motions.
Issued by National Weather Service State College PA 330 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.
/issued 224 PM CDT Mon Apr 10 2017/ A weak cold front has moved into the Permian Basin today and according to latest visible satellite and surface observations is currently sitting along a line from Big Lake, to McCamey, to Pecos. Cooler and drier air behind the front will keep any convective development this afternoon confined south of the front in the lower Trans Pecos and Big Bend.
102 PM EDT Mon Apr 10 2017 Southerly flow, under high pressure aloft, will maintain warm and dry weather into Tuesday morning. A weak cold front will bring the risk for showers or a storm Tuesday and Tuesday night. Warm advection in southerly flow on the western edge of a departing upper ridge, will support seasonably warm and dry conditions today. Deep mixing will support wind gusts to 25-30mph through this evening, which should slow moistening of the low levels some. A weak cold front will slowly make its way through the Upper Midwest tonight, reaching Western Ohio by dawn Tuesday. Initially, deep moisture will be sparse, as well as large scale ascension, so a lot of the initial energy associated with the front will get used up breaking down the strong ridge.
259 PM EDT Mon Apr 10 2017 A weak cold front will cross east through the Ohio Valley tonight and early Tuesday.
A cold front will move into the region late in the week bringing increasing winds to Utah and a chance of precipititation across the northern portion of the state. High temperatures today will be about 10 degrees warmer than yesterday in most areas, but that will still generally be about 5 degrees below normal.
521 PM CDT Mon Apr 10 2017 For tonight into most of Tuesday, dry weather will continue as semi-zonal flow to weak upper level ridging prevails.
135 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. This will allow for a continuation of dry weather, with some thin cirrus overspilling the ridge.
639 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.
In general, low temps tonight should be close to average, with readings in the 20s in the high valleys and mostly 30s over the southeast plains. At this time, the highest potential for stronger thunderstorms should be noted over far eastern/southeastern sections of the forecast district from mid to late week and possibly into the weekend where the potential for deeper atmospheric moisture will interact with localized 0 to 6 km bulk shear values of 40+ knots at times in combination with localized capes challenging 1700 J/KG and localized LI's challenging -6C respectively at times.
306 PM CDT Mon Apr 10 2017 The atmosphere ahead of a cold front identified by the fine line making its way into the eastern section of the forecast area has been capped but convective inhibition has just about been eliminated which is expected to lead to scattered thunderstorms over south central MO during the late afternoon into this evening.
1045 AM 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. The low this morning at Sky Harbor of 56 was 5 degrees cooler that the previous morning while the low of 46 at Casa Grande Airport was a full 9 degrees cooler than the previous day. A deep and nearly stationary upper level trough is forecast to sit just off the Pacific Northwest through the foreseeable future. This type of synoptic pattern will result in a series of low pressure systems affecting northern California and the Pacific Northwest, but easily remain well north of our region.
At the surface, the cold front that swept through last night, is now situated from eastern MO into the Arklatex region. Upper troughing will remain over the Pacific NW into the northern Rockies for Fri into Fri night with broad sw flow aloft over the Plains. High pressure will sink south tonight into Tue and will provide light winds in the 5 to 10 mph range through the afternoon hours.
411 PM EDT Mon Apr 10 2017 A trough of low pressure will move toward the region tonight and Tuesday.
The cold front was located just south of a Stephenville to San Angelo line at 3 PM with showers and storms developing along and just behind it in West Central Texas. GEFS plumes for both Austin and San Antonio have trended up, with the lowest member at Austin around 2", highest at 4. Some of the high resolution guidance suggests the highest amounts farther south toward the San Antonio metro area.
Increasing winds may mix out the low levels a bit more than models suggest, so kept dewpoints on the lower side of model consensus. This will put some areas of the mid state into the 20 to 30 percent min RH range, which will mainly be along the Plateau and some areas that see slightly warmer high temperatures to increase the RH spread.
312 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.
203 PM MDT Mon Apr 10 2017 The upper low will continue to move east out of northern NE. Overnight partly cloudy conditions will help to drop temperatures into the upper 20s and lower 30s with teens possible in the high country. Towards the surface some moisture will get caught up in the 700 mb flow ahead of a weak trough and bring a cloud deck over the higher terrain by tomorrow afternoon and evening.
Issued by National Weather Service State College PA 252 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.
621 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.
259 PM CDT Mon Apr 10 2017 A cold front was pushing into west-central Illinois at mid- afternoon. High pressure will start building into the area for Tuesday behind the front. Cooler conditions are expected, but temperatures will still be near normal for early-mid April. The drier air mass associated with the high will also return quiet weather to the area.
with cooler temperatures and thunderstorms erupting just southeast of the forecast area. Short wave trough in low amplititude 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.
Additional, more scattered convection will develop late this morning and this afternoon as an upper level low over northwest Nebraska early this morning moves east-northeastward into the Great Lakes region tonight and sends a cold front southeastward through our forecast area today and tonight. High temperatures will be slightly cooler today than the previous day due to the increased cloud cover, albeit still well above normal. Low level cold air advection behind the cold front along with a clearing sky and lowering surface dew points will lead to much colder low temperatures tonight, close to seasonal normals.
121 PM EDT Mon Apr 10 2017 High pressure will remain in place off the East Coast today and Tuesday, resulting in a southwest flow of unseasonably warm air.
325 PM EDT Mon Apr 10 2017 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.
337 PM EDT Mon Apr 10 2017 Dry and warm weather continues Monday with plenty of sunshine and even warmer highs in the upper 60s to mid 70s. With dew points only in the lower to mid 30s we are seeing relative humidities down into the 20 percent range across much of the area.
1212 PM CDT Mon Apr 10 2017 18z TAF issuance A cold front continues to push south toward the Pecos River early this afternoon. Low clouds will develop overnight across the Lower Trans Pecos and will push into KFST and KPEQ and possibly further.
200 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. All of the models continue the idea of slowly building ridging aloft northward into the desert southwest and advecting warmer area into the region.
