723 PM EDT FRI JUL 1 2016 A pressure ridge will extend from the Atlantic westward into the Gulf of Mexico through Independence Day. A weak pressure trough will linger in the forecast area. Overnight lows will be in the lower 70s. The models displayed surface ridging extending from the Atlantic westward into the Gulf of Mexico. North of the ridge a frontal zone was shown remaining north of the forecast area with weak lee- side troughing in the area. Expect thunderstorms mainly associated with heating and convergence into the trough or into a possible seabreeze front that may move well inland. Leaned toward the higher high temperature guidance because of the recent bias. The GFS and ECMWF displayed surface ridging extending from the Atlantic westward into the Gulf of Mexico through the medium-range period.
00Z upper air analysis indicates upper trough axis quickly moving through the Great Lakes while deep layer ridging slowly builds in from the west. This and general gradual increase in moisture will help lows to be slightly warmer overnight and not as cool as they were this morning. Adjusted the lows slightly warmer due to higher dewpoints residing around. /issued 435 PM CDT FRI JUL 1 2016/ For this weekend, deep layer ridging with anticyclonic flow will maintain hot and mostly rain-free conditions.
Freezing level at 16,500 feet, -20C level at 27,250 feet and wet bulb zero at 11,300 feet. Temperatures in most locations are in the low to middle 90s.
806 PM EDT FRI JUL 1 2016 Weak cold front brings isolated showers or storms this afternoon.
/issued 842 PM CDT FRI JUL 1 2016/ Surface analysis as 0f 8:30 PM places a cold front just south of the MEG CWA. Surface analysis this afternoon places a weak cold front from Huntingdon, Tennessee back through central Arkansas.
1035 PM EDT FRI JUL 1 2016 as expansive high pressure over the Upper Mississippi Valley will gradually build across the Ohio Valley. the cold front will exit the region while expansive high pressure over the Upper Mississippi Valley will gradually make its way across the mid Western states. the large area of high pressure centered over the Mid Western states will expand across the Lower Great Lakes. A slow moving 500mb low over Quebec and ridging over the Northern Plains states will yield a confluent flow over the Lower Great Lakes region through the remainder of the extended Independence Day Holiday weekend.
841 PM EDT FRI JUL 1 2016 Scattered showers will end by tonight as a cold front crosses the region.
945 PM EDT Fri Jul 1 2016 A cold front will pass through the area tonight. High pressure will build over the area for Saturday into Saturday night.
1125 PM EDT Fri Jul 1 2016 Showers a few thunderstorms will come to an end by late evening as a cold front moves across the area.
752 PM EDT FRI JUL 1 2016 Scattered showers and possibly a few thunderstorms will accompany a cold front across the region this afternoon.
South to Southwest flow around 15 knots or less will continue through the period as High Pressure ridge remains south of the local waters.
1239 AM EST Thu Nov 10 2016 High pressure today. A mostly dry cold front crosses Friday, with much cooler air for the weekend.
324 AM CST Thu Nov 10 2016 Quiet conditions reign across the region early this morning, with upper air and satellite continuing to show ridging being the main feature for us, while the cut off low continues to spin over the border along the desert SW and Mexico. At the surface, southwesterly winds are in place across the area, ahead of a trough axis extending through western portions of the Plains. No precipitation is expected as this disturbance slides off to the north, but an accompanying surface cold front will push through much of the CWA during the daytime hours today.
18Z surface data had high pressure from the southern Plains into the western Great Lakes. Quiet and dry conditions will be seen from late this afternoon through tonight as high pressure moves into the Ohio Valley. Lack of adequate moisture return into a already dry air mass will make for a precip-free fropa process Thu evening, and then set the stage for a rather breezy and much cooler Friday. above guidance winds from the north to northeast at 10-20 MPH and highs in the low to mid 50s.
355 AM CST Thu Nov 10 2016 An upper low continues to slowly move westward and will soon settle over the AZ/NM/Mexico boarders later today through tomorrow, keeping rain chances in the forecast on into the weekend. Clouds should remain in place again today with highs only a few degrees warmer than yesterday.
302 AM CST Thu Nov 10 2016 After an evening of clear skies and light winds allowing temperatures to drop to lows in the lower to mid 30s, temperatures have recovered to the mid 30s to lower 40s as southwest winds increased after midnight. This warmer air is going to dominate the weather today as a cold front drops into the northern plains. I've gone on the warm side of guidance with highs in the lower 60s northeast to mid to upper 60s central and southwest. Tonight, the cold front will arrive after sunset, but it will lack a strong initial cold advection push.
Cooler/drier air continuing to work into the area from the NE overnight as high clouds clear out to the E/SE.
1120 PM CST Wed Nov 9 2016 High pressure will move over the region by Thu morning. (ISSUED 501 PM CST Wed Nov 9 2016 ) High pressure will move over the region by Thu morning. Tonight Through Friday High pressure will settle into the region tonight. There may be a place or two that briefly hits the freezing mark. Despite the cooler temperatures, readings will still largely be above average for this time of year.
41 Broken high clouds prevailed over the forecast area this afternoon with mild temperatures in the low 60s north to mid 70s central. especially the Rough Ridge Fire in western Fannin County. A large high pressure system over the mid MS river valley will continue to dominate the southeast U.
305 AM CST Thu Nov 10 2016 As of 09z, a weak cold front continued to make its way across the forecast area with northwest winds across the Devils Lake basin and far northern Red River Valley. Even with plenty of sunshine again today, the cooler northwest flow will keep temperatures in the 50s across the majority of the area (possibly low 60s across the far south), although still plenty mild for this time of year. Highs topping out in the 40s will feel quite a bit cooler than the record readings as of late but still a bit above average.
A cool ridge of high pressure is settling over the Southern Plains and the Lower MS Valley this morning. Aloft, an upper low remains over Northern Mexico with the southern stream of the jet just south and east of the CWA. Today and Friday, temperatures will be near climo values and weakening CAA will continue as the ridge continues to build in.
Cooler temps expected tomorrow but still above seasonal norms. Latest CONSSHORT minimum temperatures were two to three degrees warmer than forecast. and given sky/wind forecast, cooler MIN T in inherited forecast seems more reasonable and will lower (from CONSSHORT guidance) overnight hourly temps. FROPA will push across the area in the early morning with winds turning to the northwest with cooler blyr air filtering down in its wake. High pressure drifting across the region will bring temps closer to average on Friday, but highs still should reach the 40s.
A coastal trough across the western Gulf of Mexico will continue to provide a focus for convection across the coastal sections of the CWA today and tonight as well as across the coastal waters. Best rain chances will be confined across the lower TX coast and offshore today through Friday.
Smoke from wildfires in NC and GA should not impact visibilities at TAF sites tomorrow with the low level winds from the north.
As high pressure moves south overnight, return southerly flow expected. With the southerly winds and high pressure axis south of the CWA, believe lows tonight will not reach freezing levels with short term guidance in good agreement with readings in the middle to upper 30s. Southerly winds continue to increase from 10 to 15 mph sustained in the afternoon Thursday as a cold front approaches the northern KS border. The strong warm advection through 925 mb should boost highs at least 10 degrees higher than today in the lower 70s. By Thursday night, a dry cold front will be just north of the forecast area moving through northeast Kansas overnight.
Once this upper level cold front moves southward through the rest of our forecast area the skies will clear and low temperatures will cool into the 40s. Dry and calm conditions are expected through the short term period, as high pressure will briefly build back into the region.
High pressure will settle in across the deep south keeping skies mostly clear and temps seasonal. Closed upper low in the desert SW opens and slides east to the Tennessee River Valley through the weekend. At the surface Great Lakes high pressure center drops into the Mid Atlantic states keeping easterly low level flow with fairly dry and seasonable conditions over West central and SW Fl through the weekend.
A strong upper level ridge of high pressure over the western United States will maintain dry weather conditions and above average temperatures through Friday.
1257 AM EST Thu Nov 10 2016 High pressure will settle across the lower Mississippi and Tennessee river valleys tonight. The high will move toward the Gulf Coast on Thursday while a cold front approaches the region from the northwest. The cold front is expected to pass through the area dry Thursday night into Friday.
Drier air continues to filter into the region behind a recent cold front so this will preclude the chance of fog through the morning hours. This feature will begin to lift northward through the day Thursday as an upper level trough across Northern Mexico begins to slowly fill and lift out to the north and east.
427 AM EST Thu Nov 10 2016 High pressure along with cooler and drier air will continue building into the region today and Friday. Another cold front will cross the region Friday night with limited moisture and cloudiness expected.
Behind the front across Central Alabama, tight pressure gradients around the ridge center that extends from the Texas Panhandle to the Mid Mississippi River Valley are allowing for breezy northerly winds to usher in cooler and drier air into the state. In the upper levels some wrap around cloud cover remains as the some moisture is dragged by the upper low across the state as the low moves out of the Great Lakes to the Mid Atlantic. As the ridge settles in over the Deep South tonight, gradients will relax and winds will respond and lighten. With clearing skies, cold air advection and lighter winds expect low temperatures tonight to be some 5 to 8 degrees cooler. Sunny skies are expected for Thursday under a dome of high pressure with cooler conditions as light northerly flow continues.
An upper trof will move south of the area this evening with an associated surface cold front moving south across the marine area. In the wake of the front, a cooler and drier airmass continues to move into the region through tonight. A dry and cool airmass will continue across the area on Thursday as deep layer ridging continues to build. Highs on Thursday will climb into the lower and mid 70s inland to low 70s along the coast.
Marine concerns with gusty winds with a passing cold front Thursday and Thursday night. Broad upper level ridging extends from the desert southwest into the northern plains. Water vapor imagery shows a short wave trough climbing the front side of this ridge into southern British Columbia. and will give the top of this ridge a bit of a shave as part of a consolidated area of height falls that will dig into the upper Lakes Thursday. The arriving short wave trough will push a strong cold front across Michigan Thursday night. High pressure will build quickly into the region Friday night. Impacts with cold front passage the main concern. Ahead of the cold front concerns are minimal.
1115 PM CST Wed Nov 9 2016 After a cool and frosty start this morning, temperatures have warmed nicely into the lower 60s this afternoon in most areas with full sunshine and a light southwest breeze. An upper level ridge will remain situated over the western United States acting to keep our area dry and warmer than normal. A cold front will slide southeast across the region that will turn the wind from southwesterly during the morning hours to northerly by later in the day.
High pressure remains squarely on top of the state this morning and will be the dominate weather feature today with clear skies and temperatures very close to where they are supposed to be. In the upper levels, a cut off upper low will continue to sit over west Texas and have little impact except to throw a few clouds our way on occasion. Meanwhile a cold front, that is a cold front in name only, will be entering the far north part of the state at the end of the period. Temperatures on Friday will be slightly warmer on Friday in advance of the boundary.
It will become windy Thursday and a cold front will move through but not bring any precipitation with it Thursday night. Another high pressure ridge will build in to bring fair weather Friday through the weekend. High pressure will continue in control of the wx pattern tonight bringing fair weather with mostly clear skies. Fair weather will then continue Friday as a high pressure ridge builds in from the northwest.
Dewpoints in the upper 50s along the I-10 corridor to the lower 50s in cntrl La. Northeasterly winds 5-10 kt can be expected as a ridge of high pres extends west to east from the southern plains into the lower MS valley. /issued 330 PM CST Wed Nov 9 2016/ High pressure will settle in over the next few days. Temperatures will continue to be a little above normal, especially on the highs.
1128 PM EST Wed Nov 9 2016 A ridge of high pressure over the Ohio and mid Mississippi valleys will build northeast overnight into the north country, and will remain over the region through Thursday. A strong cold front will move south from Canada late Thursday night and Friday and bring more showers to the north country. Another ridge of high pressure will build east from the Great Lakes and Mississippi valley Friday night and will remain over the north country through this weekend.
High pressure ridging will get flattened tonight as an upper level disturbance moves across southern Canada. Temperatures tomorrow will be cooler due to an easterly surface wind. Upper ridge that has been placed over the central and northern Rockies the last several days will get flattened tonight. As the wave crosses southern Canada tonight, a cold front will swing through our forecast area late, with arrival time for southern Montana being after midnight. This will provide a cooler day with high temperatures about 10 degrees lower than today.
254 AM EST Thu Nov 10 2016 High pressure will shift offshore into the Atlantic Today. A cold front will arrive from the northwest Friday morning.
322 AM EST Thu Nov 10 2016 High pressure will build into the region from the west today, then push to our south tonight. A dry cold front will move southward through the area on Friday, then chilly Canadian high pressure will build in from the northwest Friday night through the weekend. Expect highs of 61-67, and wide-ranging lows tonight of 35-42, with diminishing winds backing to WSW as lee troughing develops. This will push a backdoor cold front SSE through NC on Fri, and this front will settle well to our south Fri night as chilly Canadian high pressure drops through the Midwest and extends through the Mid-Atlantic region and NC.
The upper level low remains elongated stretching from Chihuahua to the Permian Basin and will slowly migrate to the AZ/NM line by tomorrow afternoon. Surface winds will veer to the southwest by tomorrow as well in response to the movement of the low and a surface front stretching from Hudson Bay down to northeast CO. The cold front is then expected to push through the FA starting tomorrow night and be to our south by Friday afternoon.
The 500MB ridge stretching from southern CA through the Dakotas this afternoon will become suppressed overnight, as a trough swings across the Northern Plains states. While a cold front will swing across the area Thursday morning, the parent low is way up across Hudson Bay. The main changes will be a westerly to eventually northerly winds, and cooler air sliding in. Temperatures at the sfc will only be about 5-10F cooler Thursday afternoon, and still well above normal.
Temperatures this morning ranged from the low 30s to the upper 30s. A mean ridge with a few weak upper depressions will persist over the nation's midsection through the next several days. A dry airmass associated with a large area of high pressure will push south of the area with an eventual return of the surface wind to the south.
333 AM EST Thu Nov 10 2016 An upper trough is moving off the DELMARVA coast while a weak front lingers across central Florida. High pressure is building across the OZARKS and lower Mississippi Valley and slowly sliding to the east. Near the Florida Keys we have high pressure over the area, resulting in clear skies and light easterly winds. Weak high pressure will remain in place over the Keys area with a weak front drifting southward across the Florida Peninsula toward the Florida Keys. The front will arrive late tonight with high pressure building in its wake late Friday and Friday night.
155 AM EST Thu Nov 10 2016 A Canadian cold front will bring a few light rain or snow showers to NY and PA tonight into Friday.
Temperatures will be warmer tomorrow as well with a thermal ridge in place.
The cold front that moved through last night is now well to the south with the parent upper trough moving off the North Carolina coast. Cooler and drier air filtered in today with highs only in the mid 60s to around 70. Even if the wind diminishes and temps fall quickly, lows still may be a few degrees warmer than the previous forecast in some places. This doesn't look as likely now with the wind and warmer temps but could still see it in sheltered locations so won't remove it from the forecast at this time.
With skies clearing from the northwest and dewpoints in the lower 40s to mid 30s, should be a good radiational cooling night for most of the cwa. Still expecting the cooler temperatures in the east. Looks like high pressure will move into the area by tomorrow and cool dry conditions will prevail for a few days.
An upper ridge across the Plains combined with southwest surface flow and warming temperature aloft will help boost temps into the mid to upper 60s for Thursday.
336 AM CST Thu Nov 10 2016 The upper low was located in northern Mexico just south of the AZ/NM border. Over the next few days, the upper low will begin to fill. The models show the low beginning to open up on Friday and then shear out as it moves eastward across the Southern Plains over the weekend.
An upper level ridge and low level offshore flow will produce dry and mild weather tonight through Friday morning.
High pressure will move south today with return flow for tonight through Friday morning.
A decent ridge to valley split exists with areas of dense valley fog noted as well as some frost likely starting in the coldest spots. Temperatures will continue to fall into the low-mid 30s with stratus exiting off to the south. In the wake of the cold frontal passage low clouds have prevailed across the forecast area today. With the return of sunshine on Thursday, daytime temperatures will be about 10 degrees warmer than today. With warm air advection quickly setting up, the stage will be set Thursday night for a significant ridge and valley temperature difference for overnight lows. This results in a nearly 10 degree temperature difference between the colder valleys and the thermal ridges. At weak and moisture starved cold front will pass through on Friday followed by an expansive area of Canadian high pressure building in over the weekend.
401 AM EST Thu Nov 10 2016 High pressure centered to the southwest will keep dry weather over the region today. A cold front will cross the area early Friday, followed by more high pressure and dry air for the weekend.
High Pressure building in nicely across the forecast area with temperatures cooling down into the 30s across most of the area. Warmest locations in the southern valley an higher ridges were still in the lower to mid 40s. slightly warmer southern plateau and southwest Virginia adjacent to southeast Kentucky.
High pressure is firmly in control of our weather through the short term. As winds calm overnight, temperatures will drop into the lower and middle 30s across the Missouri Ozarks and middle to upper 30s west of the Interstate 49 corridor. Some patchy fog can also be expected near our warmer lakes. High Pressure will begin to slide eastward during the day Thursday allowing for a relatively warmer flow to set up ahead of the next cold frontal boundary due into the region this weekend.
1128 PM CST Wed Nov 9 2016 GOES water vapor imagery/GFS 500mb height analysis has a huge/sprawling ridge of high pressure extending across the Interior West/through Canada and the western Great Lakes region. A mid-level trough/surface cold front drop through the region Thursday. this should warm surface temperatures into the lower/middle 60s before the front rolls through in the afternoon. High pressure builds toward the region Thursday night from southern Canada.
Scattered light to moderate showers continue to move to the W-NW over parts of the Edwards Plateau and western Hill Country where isentropic ascent is greatest as the mid-to-upper level low continues to cutoff and retrograde west over Big Bend. Very isolated light showers and drizzle rooted in the lower levels continue to slide to the SW elsewhere across South Central Texas, producing up to a few hundredths of an inch per hour. Although these showers will continue over the next several hours, rain chances will gradually decrease from east to west during the evening as the low retrogrades further west.
1000 PM MST Wed Nov 9 2016 High pressure aloft will keep dry and mild conditions with cool morning temperatures. A weak cold front will move south tonight cooling temperatures and shifting the wind to the northeast across the north and east moving up along the Continental divide by Thursday morning.
A developing lee side trough Thursday will produce some wind speeds of 15 to 20 knots at LVS and TCC. A rather weak low pressure system aloft will hang out near to just south of our border with Mexico and will be the main agent for bringing in the moisture that will feed the clouds and light precipitation. Low pressure aloft has more-or-less organized a little south of NM and will move a little farther to the west before pulling up nearly stationary from late tonight through Thu night, then slowly shear/move out Fri and Fri night.
1055 PM CST Wed Nov 9 2016 Over the next few hours, with light winds due to a high pressure area moving overhead, temperatures should be cooler than what was forecast, based on latest surface obs. This high will continue to shift to the south and we'll eventually see a light south wind.
Proximity of the departing ridge with light/calm winds and clear sky across southeast Kansas should allow for coolest mins there with better frost potential, so have issued advisory through early Thursday morning. Another Canadian airmass will advect south behind a cold front Thursday night into the central Plains as an upper trof drops southeast over the northeast CONUS into Friday.
This is due to high pressure over the center of the country and low pressure tracking through southern Canada. That Canadian low will drag a cold front through southern WI early this evening, and winds will shift to the northwest. There could be a few low clouds in the wake of the cold front overnight, but the deeper moisture does not arrive until Friday morning.
