Tomorrow, sfc ridging across the South Plains will commence to nudge eastward resulting in sfc winds veering to the northwest. This wind shift will maintain a slightly cooler and drier airmass, with temps only warming into the 60s with a few 70s across the southern zones. Sfc ridging will exit the area by the end of the week, thus sfc winds will veer to the east-southeast.
Clouds will begin to increase from west to east overnight into tomorrow which should keep overnight temperatures a few degrees warmer than last night, especially in the southern valley.
104 AM EDT Thu May 11 2017 High pressure will prevail through Thursday night as a stationary front remains to the north.
532 AM CDT Thu May 11 2017 The upper level low pressure system responsible for showers, tstms, and severe thunderstorms the past couple days is now entering the northwest Texas Panhandle as seen on latest water vapor imagery. In addition, a cold front which has moved through the OK Panhandle and parts of the northern Texas Panhandle will continue its southward journey through the remainder of the forecast area this morning, resulting in cooler temperatures for today. The upper level low pressure system should be far enough east and well into Oklahoma by sunset to allow clearing skies with no pops for tonight.
505 AM EDT Thu May 11 2017 Upper level ridge will remain over the region today with a frontal boundary across the Mid Atlantic States. The upper ridge will begin breaking down tonight as low pressure crosses the Lower MS River Valley and into the Carolinas Friday night.
The cold front will begin to slow down and become oriented from west to east across our southern counties by morning. Little change in the airmass will occur before morning, so we expect the higher surface dewpoints on top of recent rains to set the stage for some light fog to develop, especially in our northern areas that see winds diminish. Minimal airmass change before sunrise will allow the low clouds and fog to keep low temperatures on the mild side, ranging from the mid 50s near Galesburg to the upper 60s toward Lawrenceville. The slow departure of the cold front Thursday night will keep rain chances in the forecast for mainly S of I-70. The cooler air will eventually progress into central IL Thurs night and Friday. The weekend looks to be dry with a warming trend, under high pressure.
331 AM PDT Thu May 11 2017 Cold front moving through this evening.
Large upper low sitting off the coast this morning, with high clouds covering much of WA and OR. As the upper trough moves slowly east today, it will push a cold front toward the region. Showers will expand overnight and into Friday as the trough moves closer and the front swings through. 25 inches in the higher mountains and 0. 10 inches in the lower elevations.
A better chance for additional thunderstorms will begin by early to mid afternoon, as a cold front begins to move across northern and western Oklahoma. Rain and storm chances will diminish this evening into the overnight hours, as a mid and upper level trough moves east of Oklahoma.
Waves of low pressure will move eastward along this boundary.
315 AM MDT Thu May 11 2017 Widespread precipitation has just about come to an end as high pressure has started building in from the west. A few showers are possible this afternoon over the highest terrain along the Continental Divide, eastern Uintahs, and San Juans but coverage and intensity of any precipitation will be much less than seen lately. While we likely won't see any precipitation from this system, it will shift the ridge of high pressure to the east causing winds to become more southwesterly warming things up a bit. Even at that, QPF amounts are on the low side. By Friday evening, the ridge of high pressure will continue sliding to the east as a trough digs into the Pacific northwest.
Upper level low is moving east and latest GOES-R IR imagery shows warming cloud tops over the I 25 corridor and westward. Flood, Heavy Rain, Hail Concerns Continue along with Mountain Large upper low that has been with us for so many days is slowing transitioning east-northeastward. Currently, parts of southeastern Las Animas and all of Baca County are missing out on the precipitation but this should change overnight as the low and its precipitation shift east. However, these 2 counties may end up on the low end of amounts, receiving mostly light to moderate precipitation. For Thursday, upper low begins to pull east of here. Recent Forecast model soundings, PV analysis and longer term computer simulations indicate that a warmer and drier upper ridging pattern will develop over the forecast district from Thursday evening into Friday night.
For highs today, went with the warmer GFS MOS temperatures due to downslope west winds and sunny skies. It will be cooler tonight as cold front with north winds of 5 to 15 mph moves through.
520 AM CDT Thu May 11 2017 Latest water vapor imagery and upper air analysis shows a deep closed low over northeast New Mexico into Oklahoma and the Texas Panhandle. with a high pressure ridge still anchored over the western Gulf. At the surface, an elongated ridge of high pressure extends from the north-central Gulf across Florida into the Bahamas. Upper level blocking pattern continues to break down today as the upper low ejects to the east and the upper ridge continues to flatten and shift eastward in response. As the low progresses east through Friday, a sfc cold front will move across the area. The sfc front exits the region Friday night as passage of the upper trough brings in northwesterly winds aloft.
The actual cold front will only make it into western ARkansas by the end of the period with a wind shift expected. The upper level ridge that that has been the dominant feature of late has been knocked down and pushed off to the east. The actual upper level low and associated trof, currently over the TX/OK panhandles, will move slowly southeast with time and cross over the forecast area through the period. In advance of the upper system, a line of thunderstorms is expected to develop during the mid to late afternoon along the associated cold front. The precipitation chances will decrease from NW to SE during the day as the system finally departs and high pressure begins to build back in.
The exception lies at LRD where winds will vary as a weak trough moves in from the west. Winds should be lighter sustained around 10-15 KTs briefly becoming N-NE in the AFTN as the trough slides in from the west but returning out of the E-SE late in the TAF period.
127 AM EDT Thu May 11 2017 High pressure from eastern Canada will keep the area generally dry but cool into Friday. Some cirrus clouds are spilling into the region tonight along the outer edge of the uppr-lvl ridge. The uppr-low off the east coast will help keep tomorrow dry and flatten the ridge to where the wave moves south of the region. Inverted trough makes a slow advance into the area Thursday bringing clouds, but surface and upper ridge hold fast with the old low spinning off to the east. An inverted trough gets hung up in the PA mountains. Deep upper level trough moves through Ohio Friday night.
401 AM EDT Thu May 11 2017 High pressure will prevail through tonight as a stationary front remains to the north.
304 AM EDT Thu May 11 2017 Rain chances have returned today with advancing low pressure. The morning update featured adjustment to precip probabilities and weather type as low pressure emerging from the midwest is shunting a surge of warm and moisture toward the region with its eastward advance.
257 AM MDT Thu May 11 2017 Upper low near the Texas/Oklahoma panhandle region this morning will move east today, with the precipitation gradually ending. Upper ridge axis will move over the area on Friday, resulting in sunny skies and dry conditions.
1152 PM MDT Wed May 10 2017 06Z TAF CYCLE Closed upper low centered over northeast NM tonight. A potent upper level low pressure system over central New Mexico this afternoon will exit northeastward into Oklahoma late tonight. Some showers and thunderstorms will linger into Thursday from the northern mountains eastward as moisture wraps around the exiting low pressure system. A ridge of high pressure will cross at the end of the week with warmer temperatures, though a few showers and storms may return each afternoon in the northern mountains.
152 AM EDT Thu May 11 2017 Ridge of high pressure over the local area at this time will continue to move east tonight. Low pressure will move east across northern Ohio Thursday morning and then to the Carolina coast by Thursday night.
High temperatures will be considerably cooler than they have been in recent days. Upper troughing will dig into the Great Lakes on Friday, giving the persistent front a solid push southward out of the region. The trough will shift eastward over the weekend, allowing upper ridging to build into the Midwest.
227 AM EDT Thu May 11 2017 Eastern Canadian high pressure, will keep our weather generally rain-free into Friday morning. The same general pattern should continue throughout the day, as mainly transparent high cloudiness gets steered over the region, between the stubborn upper low off the New England coast and a flat ridge axis over the OH Valley/central Great Lakes regions. The low levels look to remain fairly dry, under the influence of surface ridging extending down from eastern Canada. A confluent upper-level NW flow will help eastern Canadian high pressure at the surface maintain control longer, and effectively block the arrival of deeper moisture.
346 AM CDT Thu May 11 2017 An upper trough is centered over the Texas and Oklahoma panhandles. As the upper trough moves eastward today, a weak cold front will begin moving into the area. Upper ridging will begin to develop over the region on Friday.
309 AM EDT Thu May 11 2017 High pressure will remain over the Northeast United States tonight through Thursday, as a frontal boundary extends from the Ohio Valley southeast to off the coastal Carolinas.
1224 AM CDT Thu May 11 2017 High pressure was over eastern North Dakota where skies were mainly clear and winds were light. especially eastern portions closer to the high pressure center. Utilized a blend of cooler NBM and bias corrected Mos for lows tonight. On Thursday, quiet weather is expected as upper ridge to the west pushes east towards our area. Slightly warmer temperatures expected.
A return to MVFR is anticipated tomorrow evening and night as a weak cold front approaches from the north. Cloudy skies tonight will slowly mix out on Thursday as southeast winds crank to breezy again, with Gulf high pressure still strong enough to drive the wind.
343 AM EDT Thu May 11 2017 A quasi-stationary front stretching this morning from west-central VA to northeastern NC will settle southwestward through central NC as a cold front late this afternoon through tonight. The front will stall and become stationary once again over southern NC on Fri, ahead of an area of low pressure that will track along it and up the southern Middle Atlantic coast late Fri and Fri night. An upper level low will progress from the Rockies into the lower Midwest today, then deamplify into an open wave as it tracks across the lower MS river valley on Fri. The upper level trough is progged to progress eastward through the Carolinas during the day Sat.
The upper level ridge that that has been the dominant feature of late has been knocked down and pushed off to the east. The actual upper level low and associated trof, currently over the TX/OK panhandles, will move slowly southeast with time and cross over the forecast area through the period. In advance of the upper system, a line of thunderstorms is expected to develop during the mid to late afternoon along the associated cold front. The precipitation chances will decrease from NW to SE during the day as the system finally departs and high pressure begins to build back in. Dry conditions will persist however until Tue night and especially for Wed as deep SRLY flow develops ahead of a deepening upper trough to the west.
Upper level low situated across the Panhandle this morning prog to swing into eastern OK by tonight. In addition, there is also a weak prefrontal trough across the western Brush Country that is prog to shift slightly east today. Much drier conditions are expected behind the front although am not expecting cooler temperatures. In fact, temperatures are expected to be slightly warmer with highs in the mid to upper 80s across the Victoria Crossroads and along the coast, to low to mid 90s farther west under mostly sunny skies.
413 AM EDT Thu May 11 2017 Broad and deep high pressure remains in place across the region, keeping generally warm and dry conditions over South Florida through the rest of the week. With prevailing light to moderate winds today, expect max temps to reach the lower to mid 90s over portions of the interior peninsula, along with max temps over the metro areas near 90.
629 AM EDT Thu May 11 2017 Upper level low pressure will remain south of the region today.
254 AM CDT Thu May 11 2017 Skies are partly cloudy across the forecast area early this morning with temperatures ranging from the mid 60s to the lower 70s. Temperatures will be a little cooler today with more clouds over the region as highs mainly in the lower 80s. By tonight, the cold front will move into the forecast area with more thunderstorms expected. Temperatures will remain mild tonight with lows Friday morning in the low to mid 60s. On Friday, the cold front will move through the remainder of the forecast area with more thunderstorms expected. Temperatures will be cooler behind the front with highs in the low to mid 70s. The cold front should be east of the forecast area by Friday night with rain ending by Friday evening.
The upper low that has brought the active weather to the region the past few days was seen spinning from northeast New Mexico into the western Panhandles early this morning. Instead this lift will shift east today with a cold front plunging through the FA this afternoon in the wake of the departing upper low. In addition, there may be just enough heating and moisture near the cold core of the upper low, that when combined with the frontal forcing, isolated showers and storms wrapping around the departing system could clip the far northeast zones.
317 AM EDT Thu May 11 2017 Upper level low pressure will remain south of the region today.
VFR to MVFR conditions are expected behind a cold front this evening and overnight with a northerly wind. A better chance for additional thunderstorms will begin by early to mid afternoon, as a cold front begins to move across northern and western Oklahoma. Rain and storm chances will diminish this evening into the overnight hours, as a mid and upper level trough moves east of Oklahoma.
Severe threat is the result of an upper-trough across the Four Corners region ejecting east into the Ozarks by this evening. Upper-trough will aid in destabilizing the ArkLaTex during a time of peak heating. Temperatures on Friday to climb into the mid to upper 70s as Canadian high pressure shifts south and east.
Highs tomorrow look to be around 10 degrees or so above seasonal normals again, but morning lows tonight and tomorrow night are expected to remain just a few degrees warmer than normal. Upper ridge axis moves over the forecast area tonight and begins quickly flattening tomorrow through tomorrow night as the upper low over the southwestern U. with sfc reflection revealing low pressure to its east and associated cold frontal boundary draped to its south.
416 AM MDT Thu May 11 2017 Upper level low centered over the Texas panhandle will move east across Oklahoma today. Lift associated with the upper level low is already south and east of Limon. Models indicate a tall upper ridge building over Colorado on Friday with 700 mb temperatures anywhere from about 6 deg C over the northeast corner of the CWA to around 11 deg C in the high country.
However, increasing cloud coverage should keep temperatures a few degrees cooler than yesterday. As a low pressure system approaches from the west the frontal boundary that has lingered north of our area should get shoved out of the region.
A cold front has entered into the Oklahoma Panhandle and will continue south through the morning hours. Simpson Upper level low over New Mexico will continue to slowly move east northeast overnight. As this low moves closer to the region it will help to provide enough dynamics to produce numerous showers and thunderstorms across the region. A cold front will start to move through the Oklahoma Panhandle and the northern Texas Panhandle helping to enhance the rain chances there after midnight.
This should allow for destabilization to occur before a cold front pushes south through the area this afternoon, allowing for a potential of additional development. The cold front should move southeast into VA and TN late tonight or Friday morning (there is some model discrepancy). However, it will still be close enough on Friday so that as the supporting upper level trough moves through and triggers a wave on the front, additional precip can be expected, especially in our southeast counties.
640 AM EDT Thu May 11 2017 Low pressure will move across south-central Ohio today bringing rain showers to much of the state through the morning hours.
121 AM EDT Thu May 11 2017 A surface pressure ridge will extend along the Gulf Coast through Thursday and direct a warm and dry west flow into the forecast area. Aloft, ridging will dominate and help suppress thunderstorms. The ridge will begin to break down Friday ahead of another frontal system.
Upper level ridge will build into Montana today. This will bring dry weather with warmer temperatures. Upper ridge continues to move east tonight and will be over Eastern Montana on Friday. Tightening surface gradient ahead of the low will bring stronger southeast winds on Friday which may require a Lake Wind Advisory for Fort Peck Lake. The ridge moves into the Dakotas Friday Night and flow aloft turns to the southwest.
256 AM EDT Thu May 11 2017 High pressure will remain over the Northeast United States tonight through Thursday, as a frontal boundary extends from the Ohio Valley southeast to off the coastal Carolinas.
A large low pressure system will slowly move inland today and begin to shove the ridge of high pressure to the east. This ridge has given us a couple of great spring days, and for most of the day today it will bring us one more warm day with highs in the lower 80s. FRIDAY: the cold front will pass through much of the Northern Rockies, further contributing to a greater coverage, and A GREATER POTENTIAL FOR SOME DAMAGING STORMS, with strong gusty winds and dangerous amounts of lightning. This cold front will also drop temperatures about 20-25 degrees across the entire region.
Expecting the fog to dissipate as a weak cold front works in from the west with some drier air and as the shallow low level inversion gets mixed out. Te rest of the area should see clearing skies as high pressure builds from MN. Friday is shaping up to be a nice end of the work week as a ridge of high pressure drifts southeast across the area. Under mostly sunny skies, plan on highs in the middle 60s to the lower 70s.
237 AM MDT Thu May 11 2017 Upper low near the Texas/Oklahoma panhandle region this morning will move east today, with the precipitation gradually ending. Upper ridge axis will move over the area on Friday, resulting in sunny skies and dry conditions.
515 AM EDT Thu May 11 2017 Rain chances have returned today with advancing low pressure. The predawn update featured further adjustment to precip probabilities and weather type as low pressure emerging from the midwest is shunting a surge of warmth and moisture toward the region with its eastward advance.
346 AM EDT Thu May 11 2017 Low pressure will move across south-central Ohio today bringing rain showers to much of the state through the morning hours.
624 AM EDT Thu May 11 2017 Upper level ridge will remain over the region today with a frontal boundary across the Mid Atlantic States. The upper ridge will begin breaking down tonight as low pressure crosses the Lower MS River Valley and into the Carolinas Friday night.
High pressure was slowly slipping east allowing for a low pressure system and its associated cold front to approach the two state area later tonight. Thursday a cold front is forecast to sweep across the region with showers and isolated tsra expected. A large upper level trough is currently over the northeast Pacific. This trough will gradually work to a position over the Pacific Northwest through this period. A cold front is expected to work it's way across the region Thursday. With the trough over the region late Thursday night through Friday night, varying chances of showers will continue across the area. Temps will cool off behind Thursday's cold front, with high temps by Friday in the mid 50s to lower 60s at the lower elevations. Breezy to locally windy conditions will develop behind the cold front.
Ultimately by early afternoon sufficient instability and deep layer shear is expected to reside across much of the forecast area with storms becoming most numerous ahead of the upper low and along the advancing cold front. Large hail, possibly damaging size, is the most likely hazard with the initial storms with an increasing potential for locally damaging winds as the storms become more numerous and the cold front continues southeastward. Lingering showers persist into Friday along with cooler temps.
1248 AM CDT Thu May 11 2017 A closed upper low will move from eastern New Mexico into the Oklahoma panhandle overnight. The highest pops forecast tonight are near 40 percent across the southwestern tier of counties. The upper low will move east across the Kansas/Oklahoma border. Highs were raised to the warmer CONSMOS guidance from the upper 60s to near 70.
trough will be driving a strong cold front through the forecast area this morning. Best pressure rises this morning have been across west- central Utah, with lee troughing indicated along the Front Range. Drier and calmer conditions expected on Monday as this system exits and high pressure returns.
1000 AM EST Sun Mar 4 2018 High pressure will slowly move east across the region through Monday.
/issued 306 AM CST Sun Mar 4 2018/ The upper level ridging over the Mid South today will begin to break down as a large upper level low pressure system over the west coast pushes east into the Middle and Upper Mississippi Valley. Deep moisture will advect back over the region later tonight through Monday night ahead of the approaching upper trough and weak cold front.
A potent upper level low will move into the central part of the country on Monday. The associated cold front will be moving southward across the state during the day.
HRRR/RAP/NAM keep stratus around through the day across western South Dakota/northeast Wyoming, which should keep temperatures below freezing through the day. Still looks like freezing drizzle potential from Rapid City into northwest South Dakota. Quieter and warmer weather returns for the rest of the forecast.
Drier and cooler air wl filter into the region later Mon/Mon ngt.
642 AM EST Sun Mar 4 2018 High pressure will extend from the Great Lakes southward into the region through Monday night.
957 AM EST Sun Mar 4 2018 High pressure will continue to slowly build east into Pennsylvania today and Monday bringing dry weather.
The combination of the strong pressure gradient and pressure rises behind the cold front and wind speeds aloft will likely help produce wind speeds in excess of 50 knots over portions of southeast Wyoming this afternoon from Wheatland to Cheyenne as well as near Arlington, so we have upgraded to High Wind Warnings. Expect to see a drop off or lull in the winds with some decoupling, though feel it would be prudent to leave the High Wind Warning going since winds will increase markedly again Monday morning.
After midnight cooling does occur from the east and the far eastern fcst area should drop just below freezing.
