Onshore will steadily increase along the coast south of Port Aransas today as low pressure continues to deepen over the central high plains. Isolated showers will be possible across the VCT area late tonight, however will not mention in TAFs at this time due to the low probability.
930 AM PDT Thu Apr 12 2018 A low pressure trough will move over California this morning, producing strong westerly winds over the mountains and deserts, and a few light showers, mainly western San Diego County. The trough will slide east this afternoon, allowing winds to slowly subside this evening. Cooler tonight as drier air invades the region under mostly clear skies, then warmer into the weekend under weak high pressure aloft and offshore flow.
/issued 327 AM EDT Thu Apr 12 2018/ The remnant boundary from the cold front is sitting south and east of the region this morning. With high pressure building back in at the surface from the Atlantic, easterly flow will dominate today. On Friday, the mostly dry pattern continues as the next cold front emerges over the central United States.
1016 AM MDT Thu Apr 12 2018 Just completed an update to upgrade the High Wind Watch to a warning.
1043 AM EDT Thu Apr 12 2018 A warm front will bring rain showers through the morning, mainly north of Pittsburgh. Dry weather and warmer temperatures are expected this afternoon, with widespread highs in the 70s by Friday. A band of showers continues to stream across the region north of Pittsburgh in an area of isentropic lift ahead of the advancing warm front.
743 AM PDT Thu Apr 12 2018 A low pressure system will bring rain and mountain snow across the the Inland Northwest into this morning.
A deep upper trough will move into Montana today. Will start Winter Storm Warning in the east which includes Prairie, Dawson, and Wibaux County at 00z as precip will start later in the afternoon and warmer day time temperatures will allow for more rain than snow this afternoon. We started off a bit warmer this morning than expected and thus models have given our southern zones less snow for this afternoon. TFJ Upper trough moves into Montana and Wyoming tonight with a closed upper low forming over Wyoming. The closed low moves into the central plains Friday morning and the moisture moves to the south and east which will allow the snow to end.
It will be warm and dry with plenty of sunshine, and with the low relative humidity values and significant winds the fire danger SPS still looks on track for SW VA.

1030 AM CDT Thu Apr 12 2018 Flat upper ridging over the lower MS River Valley, strong WAA, and abundant sunshine will result in temperatures topping out in the low to mid 80s today, several degrees above seasonal normals. Showers to increase in coverage this evening across southeast Oklahoma and northeast Texas with isolated thunderstorms possible after midnight as upper-trough begins to deepen and swing east across the Red River Valley. Conditions to quickly deteriorate on Friday as upper-trough deepens across the southern and central Plains. Severe storms are forecast to develop across the ArkLaTex on Friday afternoon ahead of a cold front. With surface temperatures forecast to approach a warm 80 degrees on Friday, combined with rich low-level moisture and cooling aloft ahead of the approaching trough will allow for sufficient destabilization to support rapid thunderstorm development.
520 AM MDT Thu Apr 12 2018 Current surface analysis shows developing low pressure over western WY, with a frontal boundary extending east-southeast into the central Plains. Upper level analysis shows weakening ridge over the plains, with large scale trough digging southeast across the Pacific NW. Strong jet extends around the base of the trough and into the northern Rockies and Plains.

Dry weather and warmer temperatures are expected this afternoon, with widespread highs in the 70s by Friday. A band of showers continues to stream across the region north of Pittsburgh in an area of isentropic lift ahead of the advancing warm front.
1043 PM EDT Thu May 4 2017 A big change in the weather will take place starting tonight as a large upper level trough of low pressure takes shape over the eastern third of the country. This large trough of low pressure will move into the Northeast and stall over the area this weekend.
830 PM MST Thu May 4 2017 A strong high pressure system will continue over the region on Friday, producing another day of unseasonably hot temperatures on the deserts.
Clear skies expected through the period with weakening north winds this evening as high pressure settles into the region.
718 PM EDT Thu May 4 2017 A big change in the weather will take place starting tonight as a large upper level trough of low pressure takes shape over the eastern third of the country. This large trough of low pressure will move into the Northeast and stall over the area this weekend.
854 PM MDT Thu May 4 2017 Forecast on track with high amplitude upper level ridge building into the region. Large high-pressure ridge off to the west will continue to move over the region tonight and into tomorrow bringing warmer and drier conditions. Tomorrow's temps will be about 10 degrees warmer. Warmer temperatures in the high- country will also accelerate snow melt.
An upper level low is parked over the Midsouth and isn't going anywhere quickly. Temperatures range from the lower 50s west, with upper 50s near the Tennessee River. Latest GOES water vapor imagery shows an upper level low pressure center just to the east of Memphis, Tennessee. At the surface, a low pressure system is lifting north across the Kentucky and Tennessee border.
611 PM CDT Thu May 4 2017 WV imagery this afternoon showing a well amplified upper level ridge situated over the wrn CONUS with mostly clear skies prevailing across the region. broad high pressure was in control from the Dakotas to the srn Plains. The upper ridge building in from the west will ensure high and dry conditions prevailing tonight and Friday. MAV/MET numbers are pretty similar as well as reasonable with lows tonight in the low 40s and Friday highs in the low/mid 70s.
much cooler air will move in with the upper low dropping into the region. Moisture and weak lift rotating around the low will continue the scattered showers and low clouds.
Wind speeds continue to decrease over the Gulf waters as high pressure ridge moves into the region. Clear skies expected through the period with weakening north winds this evening as high pressure settles into the region.
/issued 524 PM CDT Thu May 4 2017/ Vigorous upper level trough continues to spin across the Mid Miss/Western Tenn Valley this evening with an expansive CU/AC field on its west flank. /issued 304 PM CDT Thu May 4 2017/ Gusty nw winds behind stg cold front late yesterday eve meeting marginal LWA criteria. Continued nw flow aloft with stg western conus ridging creating enough omega blocking to keep area dry for about a week. Pacific airmass will finally sneak underneath an even larger upper low that will be located well off upper Pac coast, with a weak front and perhaps some Pacific moisture to augment gradually increasing southerly low lvl flow.
610 PM CDT Thu May 4 2017 At 500mb there is a deep trough over the northeast Pacific Ocean followed by a large ridge over the western CONUS. There is a deep trough extending from Hudson Bay low to a closed low over the Mississippi Valley. Missed the low temperatures over western Nebraska this morning using a blend for the forecast. With warmer temperatures aloft lows will hold in the mid to upper 30s with some low 40s over north central Nebraska. This is about 3F to 5F cooler than the blend.
607 PM CDT Thu May 4 2017 Quiet conditions in place across the area this afternoon, with upper air and satellite data showing well amplified northern flow in place, set up between ridging extending through the Rockies and low pressure moving into western Kentucky/Tennessee. At the surface, high pressure is centered just west of the CWA, keeping winds northerly. Well amplified northerly flow remains in place in the upper levels, though the ridge axis is gradually shifting further east, moving onto the High Plains Friday night. At the surface, that high pressure just off to the west will continue to drift east into the area tonight into tomorrow morning, and takes quite a while for the axis to push east of the CWA.
The cold front, with currently just a few showers on it, is approaching Tallahassee and will move west to east across our area after midnight. Cooler and drier air will filter into the area behind the front with below normal temps expected on Friday. A scattered to broken line of showers and a few thunderstorms along a cold front will push through the area late tonight with a period of MVFR ceilings. Otherwise, VFR conditions will prevail on Friday as skies clear behind the cold front. Southerly winds 20 to 25 knots this evening will become southwest and gusty with the passage of a cold front early Friday morning. We may need to upgrade to a gale warning for Friday night with the passage of a secondary cold front.
817 PM EDT Thu May 4 2017 A big change in the weather will take place starting tonight as a large upper level trough of low pressure takes shape over the eastern third of the country. This large trough of low pressure will move into the Northeast and stall over the area this weekend.
Strong northwest flow will continue over the marine area through Friday as the MSLP gradient remains tight between low pressure lifting across the eastern U. and a ridge of high pressure building over the Plains. MVFR to low end VFR ceilings will continue for another few hours across coastal portions of the region, including around KMOB/KBFM/KPNS before the low clouds are expected to gradually scatter later this evening. Showers located along a cold front currently over the mid section of the forecast area will be located east of the area by the beginning of the period (or very nearly so) as the cold front continues off to the east, leaving dry conditions prevailing for tonight.
Upper level ridge of high pressure gradually drifts east across the northern Rockies and MT though Friday for continued mainly clear skies and VFR conditions. Even if flooding does not occur, the higher stream/river flows and levels may cause some impacts to agriculture and recreation. Fair weather will persist tonight through Friday morning as an eastward-drifting high pressure ridge remains in control. By Friday afternoon, the eastern flank of an upper trough will begin overspreading the CWA from the west.
614 PM CDT Thu May 4 2017 Rain continues to wrap around an upper low now centered over northeast AR affecting parts of the eastern cwfa. The upper low will move off and the rain will finally end early tonight.
845 PM PDT Thu May 4 2017 Cooler with a threat of mainly mountain showers and thunderstorms into the weekend.
Also, as high pressure builds over the region, winds tomorrow will also be light and variable.
As of 2 pm, the cold front is now through Tuscaloosa and will be moving into the Birmingham Metro by 3 pm and into the Montgomery metro by 4 pm. Moderate rain and an isolated thunderstorm can not be ruled out right along the cold front, but outside of that that rain is the predominate weather through tonight. Once the cold front works through then the main upper low will begin to slide into the area.
625 PM CDT Thu May 4 2017 VFR and clear skies with light winds in a zone of high pressure through Friday. Before then, quiet weather is expected through the weekend with temperatures warming up as a ridge moves overhead.
It's associated with a mid level trough pushing through. Increasing northeast winds and building waves on the back side of low pressure passing by to the southeast will bring small craft advisory conditions later this evening into Friday evening. Low pressure will intensify slightly as it moves slowly east across the Ohio River Valley through Friday. Skies should start out sunny Friday, but approaching upper trough will bring increasing clouds from northwest to southeast late in the afternoon. Sharp upper trough should bring scattered or broken area of showers and possible thunderstorms Friday evening.
1140 PM CDT Thu May 4 2017 At 500mb there is a deep trough over the northeast Pacific Ocean followed by a large ridge over the western CONUS. There is a deep trough extending from Hudson Bay low to a closed low over the Mississippi Valley. Missed the low temperatures over western Nebraska this morning using a blend for the forecast. With warmer temperatures aloft lows will hold in the mid to upper 30s with some low 40s over north central Nebraska. This is about 3F to 5F cooler than the blend.
It will turn much, MUCH cooler Friday with highs 30 degrees cooler than today across the Interior West Side.
1139 PM CDT Thu May 4 2017 Rain continues to wrap around an upper low now centered over northeast AR affecting parts of the eastern cwfa. The upper low will move off and the rain will finally end early tonight.
High pressure will dissipate over the area in the afternoon and keep winds generally below 12kts aside from the occasional gust.
Maliawco Water vapor imagery and 500 mb height field shows the large ridge of high pressure firmly in control over the majority of the western CONUS with 580dm measurements already reaching as far north as SW Montana. The short term forecast will continue to be dominated by this welcome ridge, giving the area the warmest temperatures we've seen for about 215 days.
/issued 249 PM CDT Thu May 4 2017/ SHORT TERM (Tonight through Friday Night):500mb low/trough across the southeast United States and 500mb ridge across the western U. high pressure across the state will provide clear skies across the CWA tonight into Friday.
/issued 959 PM CDT Thu May 4 2017/ Skies to continue to clear this evening in wake of departing upper low across the lower MS Valley. With that in mind, did make adjustments to lower overnight low temperatures by a few degrees for much of the area except for parts of East Texas where many locations are still in the lower 60s.
High pressure over the area tonight will shift east Friday and southerly flow will develop.
/ISSUED 300 PM CDT Thu May 4 2017/ Temperatures as of 3 PM CDT have risen into the low to mid 70s in many locations around Southeast Texas with breezy to windy and sunny conditions in place this afternoon.
1143 PM CDT Thu May 4 2017 Diurnal CU have developed on the backside of the upper low. This will set the stage for what looks like a fabulous weekend across the area as the upper ridge to our west begins to influence the region more and more.
616 PM CDT Thu May 4 2017 Diurnal CU have developed on the backside of the upper low. This will set the stage for what looks like a fabulous weekend across the area as the upper ridge to our west begins to influence the region more and more.
Visible satellite imagery shows some low clouds continuing to try and wrap into the area from the N on the backside of the upper trof axis to our east. /issued 411 PM CDT Thu May 4 2017/ Northwesterly flow aloft continues as the upper level trough shifts eastward and deepens along the east coast. An upper level ridge continues building over the Rockies into this weekend, ushering deep northwest flow and dry continental air into the region. These offshore winds will decrease over the weekend as the high settles over the coastal waters.
Gusty wind and lightning still appear to be the biggest threats, though small hail and brief heavy showers will be possible as the cold front advances through the forecast area.
Breezy winds are picking up ahead of an approaching cold front, with another round of showers and thunderstorms forecast to move through the waters overnight along the actual frontal boundary. Conditions will continue to improve through the weekend as high pressure fills in from the west.
A cold front will move to the coast around 11Z then spread inland Friday morning into early Friday afternoon with light showers as well as areas of MVFR and mountain obscuration mainly from the Cascades westward. Seas will remain swell dominated tonight while a cold front moves through the waters. High pressure offshore and a thermal trough inland will bring increasing northwest winds Friday through the weekend.
544 PM MDT Thu May 4 2017 Large upper ridge will build across the central Rockies and adjacent plains through the short term period, resulting in mostly clear skies, light winds, dry and warm conditions. This is due to a ridge in place over the CWA with a developing closed low pressure system over the desert southwest.
A strong upper level ridge currently over the Rockies will gradually push its way eastward tonight and Friday, with the eastern edge of the ridge reaching the western high plains by Friday evening. Warmer air will continue to get pulled into the region, with 925mb temps in the +20 to +25 deg C range and 850mb temps +13 to +17 deg C range Friday afternoon. Low temperatures tonight will generally be in the lower to mid 40s, with highs on Friday in the mid 70s to lower 80s. The period begins with an upper ridge over the central CONUS with much above normal temperatures expected.
MVFR to low end VFR ceilings will continue for another few hours across coastal portions of the region, including around KMOB/KBFM/KPNS before the low clouds are expected to gradually scatter later this evening. Showers located along a cold front currently over the mid section of the forecast area will be located east of the area by the beginning of the period (or very nearly so) as the cold front continues off to the east, leaving dry conditions prevailing for tonight.
Unfortunately sub-freezing temps appear likely over nern areas in proximity to colder side of low level thermal trough. Thereafter short amplitude ridging aloft spreads ewd into the wrn lakes mid week ahead of next upstream bowling ball ejecting out of the Rockies.
956 PM CDT Thu May 4 2017 WV imagery this afternoon showing a well amplified upper level ridge situated over the wrn CONUS with mostly clear skies prevailing across the region. broad high pressure was in control from the Dakotas to the srn Plains. The upper ridge building in from the west will ensure high and dry conditions prevailing tonight and Friday. MAV/MET numbers are pretty similar as well as reasonable with lows tonight in the low 40s and Friday highs in the low/mid 70s.
MVFR cigs could still impact far inland portions of our forecast area through early Friday morning as an upper low slowly moves eastward over the TN Valley. Strong northwest flow will continue over the marine area through Friday as the MSLP gradient remains tight between low pressure lifting across the eastern U. and a ridge of high pressure building over the Plains.
644 PM CDT Thu May 4 2017 A weak trough axis lies across the forecast area this afternoon, which has produced showers over portions of the MN Arrowhead this afternoon. Expect temperatures to be warmer than last night with warm air advection going on aloft, so have gone with some low to mid 30s up the north shore and inland Arrowhead, but then mid and upper 30s to around 40 elsewhere. This should also mix down some dry air and have concerns for fire weather conditions for areas north of the Iron Range with RH values dipping into the low 20s.
910 PM EDT Thu May 4 2017 Low pressure will maintain rain chances and colder temperatures through the weekend. Coverage in rain will increase overnight as low pressure tracks northeast from Kentucky.
Upper level ridge of high pressure maintains mainly clear skies and VFR conditions though Friday afternoon.
Still expecting high pressure to keep us clear, warm, and dry through the night.
750 PM EDT Thu Oct 26 2017 Low pressure will move across the area this evening then exit the area.
Morning lows should be about 10 degrees cooler than current temperatures, in the low 50s across most of the area.
Cold front is still on its way. Hires data suggests we'll start seeing a broken line of shra develop once it nears the Highway 59 area in the morning.
Cold front currently pushing into southeast Oklahoma/northwest Arkansas late this evening. Primary focus this evening has been the strong winds behind a cold front working through the Plains. In addition, much cooler temperatures are surging in behind the front.
1005 PM EDT Thu Oct 26 2017 High pressure will remain over the Carolinas through Friday night.
/issued 251 PM CDT Thu Oct 26 2017/ 19z surface analysis shows the cold front from near Blackwell to Enid to Clinton to Quanah, moving southeastward. Cold advection will continue overnight and a small section of northwest Oklahoma could see freezing or sub-freezing temperatures by morning. Pressure gradient and boundary layer mixing leads to some uncertainty on temperatures during the early morning, so confidence that all/most locations within the current Freeze Warning (Woods, Woodward, Harper and Ellis counties) will fall to or below freezing is not particularly high. Much cooler temperatures are expected tomorrow. This will cause temperatures to fall to sub-freezing lows that will be colder than we have seen across the area since last March.
A strong cold front continues to make quick progress across the TX Hill Country into Central OK and this front will be knocking on the TYR/TXK terminal door at 27/12z. /issued 213 PM CDT Thu Oct 26 2017/ Warm sunny day across the area, but with big changes to come as the strongest cold front of the season barreling down into the central plains.
No forecast changes planned for this evening's update as high pressure has taken a firm grip over the area. Changes are in store tomorrow night, though as a cold front is set to push through the state.
Southwesterly winds should remain around 10 KT overnight thanks to a decent pres gradient between high pres over the northern Gulf and a cold front to the northwest. Significantly warmer temperatures can be expected overnight with warming low level southerlies reestablished. Deep low pressure currently over Minnesota will maintain a southeast trek overnight. Feature will advance a strong cold front across the forecast area through the day reaching the lakes area of interior southeast Texas toward late morning and exiting lower Acadiana by early evening. A strong cold front will advance across the near coastal waters Friday afternoon and evening. Dry high pressure will then become reestablished for the weekend with northerly winds gradually diminishing.
1014 PM EDT Thu Oct 26 2017 Low pressure will move across the area this evening then exit the area.
709 PM CDT Thu Oct 26 2017 With the cold front still slated to move across the area from the north starting around sunrise. /ISSUED 403 PM CDT Thu Oct 26 2017/ The approaching cold frontal boundary that is currently located across the southern counties of the Texas Panhandle will provide a weather change for the end of the work week. There may be a pre-frontal trough just ahead of the main boundary that shifts winds around to the north a couple of hours ahead of the main front. The main cold front is forecast to pass across the BCS area between 11 and 13Z.
1032 PM MDT Thu Oct 26 2017 Snow and wind are decreasing across the forecast area Thursday afternoon as a vigorous cold front pushes farther to the south of Wyoming. Areas where the fresh snow cover struggles to melt late this afternoon could be down in the lower teens.
Winds will increase during the next several hours as the surface pressure gradient tightens up ahead of an approaching cold front.
Primary focus this evening has been the strong winds behind a cold front working through the Plains. In addition, much cooler temperatures are surging in behind the front.
720 PM EDT Thu Oct 26 2017 High pressure will remain over the Carolinas through Friday night.
