210 PM MDT Tue Nov 1 2016 A cold front will move across the area after midnight shifting winds to a northern direction, speeds generally 10 mph or less. Afternoon temperatures cool about 5f to 7f per 850mb temperatures with readings in the low to mid 60s.
130 PM EDT Tue Nov 1 2016 High pressure will extend across the Middle Atlantic and Carolinas through Wednesday.
/issued 1017 AM EDT Tue Nov 1 2016/ High pressure to the north of the region will maintain east to northeast flow over South Florida today.
An upper level low remains parked over Northern Mexico, West Texas, and Southern New Mexico this morning. Pacific moisture continues to stream into East Texas and Louisiana around the south and east of the upper low. Also, high pressure at the surface remains centered Texas. Highs for today are on the low end of guidance since cloud cover may hang around a bit longer than models are expected, however a few peeks of sun may occur during the afternoon. Through the next few days, the upper low will gradually weaken and then eject out into the plains. With the upper low to the west occasional bouts of high and mid lvl clouds will occur.
316 AM EST Fri Nov 11 2016 A strong cold front will bring a few light rain showers and gusty winds to New York today.
947 PM MST Thu Nov 10 2016 Updated Aviation Section High pressure continues to dominate the forecast over the central Rockies on Thursday afternoon.
346 AM CST Fri Nov 11 2016 A cut-off upper-level cyclone continues to spin over the southern Rockies early this morning, detached from strong northwesterly flow aloft over the Great Lakes.
a flat ridge will continue across the ern Gulf and over central FL with some scattered cirrus moving in from the west late in the day. Light NW flow overnight will veer to NNE/NE in the low levels late.
/issued 943 PM CST Thu Nov 10 2016/ Still dealing with mid and high level cloud cover streaming ovhd from the south and southwest due in part to a stubborn area of low pressure across old Mexico and ssw flow aloft downstream of the trough across our region.
1216 AM EST Fri Nov 11 2016 High pressure will shift south of the region tonight, as a weak cold front moves through the area early on Friday, with no precipitation expected. This cold front will cross the Ohio Valley early Friday morning, keeping overnight lows relatively warm around 40 degrees compared to last night's low to mid 30s. High amplitude troughing over the eastern half of the US and Canada is gradually moving east, with one segment shearing out as it enters the Great Lakes and Ohio Valley regions. A reasonably-well-defined cold front is expected to move through the region Friday morning, but with the very dry air mass in place, very little impact is expected to the weather. Despite the presence of the cold front on Friday, temperatures are still expected to be generally diurnal, though cooler than on Thursday.
1241 AM EST Fri Nov 11 2016 A cold front will pass through the region Friday bringing the coldest air of the season to the area Friday night with a widespread freeze expected. Lows tonight will bottom out in the low to mid 40s. Mild swrly flow this aftn will swing around to the north late tonight in association with a fast moving cold front trailing from short amplitude trough shifting through srn QB.
1137 PM EST Thu Nov 10 2016 High pressure will build over the region through mid week. A strong cold front will sweep through area Friday morning, followed by cooler continental high pressure filling in over the weekend. High pressure will hold across the region overnight as a weak lee- side trough develops across the Carolina Foothills. Surface dew points have rebounded into the lower to mid 40s at many observation sites at 02Z and recent trends suggest our forecast temps should be in good shape overall. Low level dry conditions will develop, with afternoon min RH values dipping into the low to mid 20s well inland.
308 AM CST Fri Nov 11 2016 The short term continues to be dominated by a quasi-stationary h500 ridge across the northern plains. Friday will be cooler but above normal with highs from the 40s east to near 60 west. In the extended the h500 ridge will gradually flatten and allow a more progressive flow to enter the northern plains.
A cut off upper low over northern Old Mexico is providing some mid level activity over the Texas Coast.
Ridge of high pressure is situated across Middle Tennessee this evening with clear skies and light/calm wind.
a weak cold front was positioned from New Mexico through Eastern Kansas. Cold air advection and northerly flow behind the front should help to keep afternoon temps slightly cooler compared to yesterday.
Temperatures will be a few degrees warmer tonight as a cold front moves into se Georgia which will bring an increase in clouds and winds after midnight. NE surge of winds as High pressure builds north of the region and NE winds will increase to 15-25g35 mph along the coast with lesser winds inland.
The wind direction will be primarily westerly until a cold front veers the wind to the north on Friday. /ISSUED 321 PM CST Thu Nov 10 2016/ An upper low can be seen on satellite spinning over Northern Mexico this afternoon, providing a steady stream of Pacific moisture and associated high cloudcover northeastward across Central and South Texas. At the surface, a high pressure ridge extends from North Texas into Arkansas. Weak isentropic ascent continues over our far southern counties above the cool high pressure dome, but moisture and lift appear too minimal for anything more than some low clouds and a few sprinkles. A seasonably cool and mostly clear night tonight will give way to mostly sunny and warmer conditions (highs in the mid 70s) Friday.
1015 PM MST Thu Nov 10 2016 High pressure will continue to dominate the weather across western and central Wyoming through Friday with dry and unseasonably mild weather.
214 AM CST Fri Nov 11 2016 Early morning water vapor imagery and 00z upper-air analysis revealed a high-over-low blocking pattern present from western Canada to northwest Mexico with a downstream trough amplifying from Ontario into the Great Lakes. In the low levels, a cold front stretched from the Great Lakes through lower Missouri Valley to central High Plains as of 06z.
1225 AM EST Fri Nov 11 2016 High pressure will expand from the west tonight. A dry cold front will move across Friday night, bringing the coldest air of the season.
950 PM MST Thu Nov 10 2016 UPDATED AVIATION SECTION High pressure at the surface and aloft continues to maintain clear skies and light winds across the forecast area. High pressure aloft will continue the clear skies, light winds, and VFR conditions over the area through at least Friday evening.
208 AM MST Fri Nov 11 2016 Water vapor shows upper ridge extending through the nrn Rockies into the nrn plains. high pressure ridge covers the Dakotas.
remains under a strong upper level ridge, with the Pacific Northwest under a southwesterly upper level flow. This pattern should begin to shift east slightly Friday and Friday night as a Pacific weather system moves into the ridge and the PACNW coast. Do expect the fog at the lowest elevations to gradually lift into a low cloud deck overnight as the fog/low cloud area grows.
915 PM MST Thu Nov 10 2016 Latest upper air analysis shows the cut-off low nearly stationary over Northern Mexico with a ridge arching over the Intermountain West. At the surface a cold front was over the Northern Plains accompanying a subtle upper level short wave trough southward. Behind the trough winds had turned to the north and were breezy at times. Tonight the cold front will move through the area. Highs will be 15-20 degrees cooler than today.
440 AM EST Fri Nov 11 2016 Cooler air will continue to filter into the region today as a strong southern Canada high pressure system drops southeast through the western Upper Great Lakes through tonight. Continued cold air will advect into the region as strong surface anticyclone over south central Canada slides southeast into the Upper Mississippi Valley/western Upper Great Lakes by this evening. For tonight the ridge becomes elongated e-w through the southern Great Lakes and will allow for quick decouple/idyllic longwave radiant losses upon sunset. Initial upstream blocking pattern maintains high latitude northern belt with only dry/rather weak clipper features Mon evening/night and again Tue night. Thermal moderation to again above normal temps for much of the week, reinforced by midweek central CONUS ridging in advance of significant amplitude wave into west coast about Wed.
1239 AM EST Fri Nov 11 2016 A strong cold front will bring a few light rain showers and gusty winds to New York today.
Cold front will move over northwest Oklahoma terminals toward 12Z and continue southward over rest of terminals through 18Z. Low temperatures will fall into the lower 40s across a greater portion of the area than previously expected. Increasing cirrus across the northwest will likely slow the temperature fall later this evening and through the night, but a few locations may still fall to around 40 as a weak cold front progresses through late tonight. Cold front will move into far northwest Oklahoma toward 12Z and continue southward over rest of terminals through 18Z.
1234 AM EST Fri Nov 11 2016 High pressure will continue to build into the region through Friday. A cold front with limited moisture will cross the region Friday night, ushering in dry and much cooler weather for the weekend.
101 AM EST Fri Nov 11 2016 Aviation Gusty southwest winds continued this afternoon across the lower peninsula of Michigan in advance of a cold front.
A cold front will continue to sink south this morning with high pressure building in from the northeast. Highs today will be cooler than compared to yesterday with values peaking in the mid to upper 50s. For tonight, winds will weaken as high pressure continues across the greater region. With said high pressure and weak winds, will continue with the freeze watch in the southeastern zones as is.
25/Owen Northerly flow will be in place as a ridge settles in over the Southern States through Friday. Temperatures will be cooler this week and into the weekend and remain rain free through the weekend. Overnight lows either side of 40 degrees (F) are forecast, with a few locations that could fall just outside the lower end of this range. Upper-level moisture fields show a plume of higher humidity values advecting toward Alabama this evening and Friday around a meandering upper low centered along the Mexico and Arizona/New Mexico border land.
347 AM CST Fri Nov 11 2016 (Today thru Sun) Cold front is currently located over central IL this morning.
/Issued 549 PM CST Thu Nov 10 2016/ For the 00Z TAFs, a cold front will move across the terminal sites later tonight with north winds in its wake.
309 AM CST Fri Nov 11 2016 Cold front across the northern Texas Panhandle will continue to sweep southward and should be south of the CWA by around sunrise. The light winds and mainly clear skies should allow temperatures to fall to around freezing or below in the Freeze Watch area. Dew points above freezing Friday evening are going to have to drop fairly quickly to allow temperatures to fall to around freezing for any period time tonight.
340 AM EST Fri Nov 11 2016 Drier and cooler air mass moving South tonight with high pressure building over the se states will provide pleasant weather across South Florida through the weekend. Short term models continue to show weak gradient with ridge building over the se plains helping to keep lighter winds and dry weather across South Florida. Temperatures will remain in the low 80s with abundant sunshine. As dry air settles in across South Florida, low temps Friday night will be a little bit cooler compared to previous night with lows ranging from the upper 50s to near 60s on the east to southeast portion of the peninsula.
313 AM CST Fri Nov 11 2016 The upper-level pattern across the CONUS is quite messy with amplified ridging across the Western CONUS and a cutoff low undercutting the ridge across the Southern Rockies. The main forecast highlights through the end of the week are cooler more seasonable temperatures and the potential for slightly below or near freezing overnight/early morning temperatures resulting in patchy to widespread frost. As the above mentioned cold front continues to push south of the state today, a strengthening post frontal pressure gradient will promote breezy north-northeast winds throughout the late morning and afternoon hours.
328 AM EST Fri Nov 11 2016 Colder airmass arriving with a cold front today and tonight.
1138 PM CST Thu Nov 10 2016 Surface analysis this afternoon features a cold front dropping through the region. This cold front has no moisture to work with, so coming through cloudless and dry. Quiet/dry/cooler weather on tap for Friday/Friday night as Canadian high pressure drops through the region. Ideal radiational cooling setup for Friday night with ridge overhead/clear skies/very light/calm winds.
/issued 854 PM EST Thu Nov 10 2016/ A dry and cooler air mass continues to filter into the region in the wake of a frontal passage.
A weak front will move across the area later today to reinforce cooler air.
400 AM EST Fri Nov 11 2016 A weak cold front will push south across the region this morning. A weak cold front currently pushing into northern Ohio will continue to work its way south through our area this morning. This should also help keep temperatures on the cooler side, ranging from the lower 50s in the north to the mid to upper 50s in the south.
307 AM CST Fri Nov 11 2016 High pressure means decreasing northerly winds with ample sunshine today.
418 AM EST Fri Nov 11 2016 A cold front will bring a shower or sprinkles and clouds today.
339 AM EST Fri Nov 11 2016 A strong cold front will bring a few light rain showers and gusty winds to New York today.
1040 PM CST Thu Nov 10 2016 Initial cold front or wind shift line moved across central and southern Minnesota this afternoon. A secondary cold front and associated short wave, was evident across northern Manitoba this afternoon. Highs tomorrow will be closer to normal with readings in the low to mid 40s.
25/Owen Northerly flow will be in place as a ridge settles in over the Southern States through Friday. Temperatures will be cooler this week and into the weekend and remain rain free through the weekend.
1157 PM EST Thu Nov 10 2016 A cold front will progress through the area overnight with northwest flow expanding south across terminals during first few hours of the forecast. Any ceilings will erode quickly from mid/late afternoon on as drier air works into southeastern Michigan with building high pressure. Winds will veer to northwest between 06z-08z as a cold front passes. Cold frontal passage will cause h850 temps to drop into the mid single digits by Friday afternoon, but late arrival of the thermal trough will lead to a delayed response in temperatures. Aggressive building of the surface anticyclone will scour out clouds Friday night, but the gradient may be borderline strong enough to prevent decoupling. Quiet weather dominates through the remainder of the work week as high pressure takes hold.
1229 AM EST Fri Nov 11 2016 A cold front will bring a few showers and clouds today.
238 AM CST Fri Nov 11 2016 A dry cold front was pushing southward across the central IL forecast area early this morning having reached the I-70 corridor as of 2 a.
255 AM EST Fri Nov 11 2016 Colder airmass arriving with a cold front today and tonight.
305 AM EST Fri Nov 11 2016 A strong, dry cold front will move through the area tonight. Cool high pressure will build in from the northwest over the weekend.
Upper ridge currently over the Rockies will begin to build back into the Plains today. A fairly cool air mass with 925mb temps around the zero C mark will remain over the area, although some warmer temps will begin to move in late in the afternoon. Not a lot of mixing for much of the day, but with plenty of sunshine and a dry air mass, getting on the warmer side of guidence is possible.
1244 AM EST Fri Nov 11 2016 A gusty southwesterly flow of mild air will persist tonight into early Friday, before a strong but relatively dry cold front drops south through the state.
437 AM EST Fri Nov 11 2016 Cooler air will continue to filter into the region today as a strong southern Canada high pressure system drops southeast through the western Upper Great Lakes through tonight. Continued cold air will advect into the region as strong surface anticyclone over south central Canada slides southeast into the Upper Mississippi Valley/western Upper Great Lakes by this evening. For tonight the ridge becomes elongated e-w through the southern Great Lakes and will allow for quick decouple/idyllic longwave radiant losses upon sunset. Initial upstream blocking pattern maintains high latitude northern belt with only dry/rather weak clipper features Mon evening/night and again Tue night. Thermal moderation to again above normal temps for much of the week, reinforced by midweek central CONUS ridging in advance of significant amplitude wave into west coast about Wed.
322 AM CST Fri Nov 11 2016 A cold front was making its way across the forecast area early Friday morning, and will push through the entire area by sunrise. Should see rather effective radiational cooling although the pressure gradient will remain a bit tight in east central KS and could keep a breeze through the night with slightly warmer temperatures resulting. Either way, much of the area will again flirt with sub-freezing temperatures with the best chance in northern KS. but the area can expect frost and some freezing conditions tonight.
256 AM MST Fri Nov 11 2016 Some high cirrus clouds are drifting in over the area tonight as a low pressure system centered over the New Mexico and the Mexican border sends some upper level moisture into Colorado. With this in mind expect temperatures to be a few degrees cooler today, but still above normal for this time of year.
309 AM CST Fri Nov 11 2016 As an amplified ridge prevails across the western half of the country, a cutoff low continues to spin around the desert southwest and north central Mexico. This increase in winds is mainly associated with the increasing pressure gradient ahead of a cold frontal passage later this evening into the overnight. The nearly zonal oriented cold front should then pass over the region between 00Z-03Z (6PM-9PM) tonight. Antecedent dry profile will preclude and precipitation from occurring with this cold front passage. Temperatures should rise only into the low to mid 60s.
919 PM MST Thu Nov 10 2016 High pressure ridging and its axis over the Pacific northwest will result in a northwest flow aloft across our forecast area tonight. A few clouds along the edge of this ridge will move southeast across the area overnight, but generally mostly clear skies will prevail. The high pressure ridge will shift east Thursday bringing sunny skies along with warmer temperatures. Upper ridge remains in place tonight through Friday night with mostly clear skies and temperatures remaining above normal.
329 AM EST Fri Nov 11 2016 A quiet morning on tap across the eastern Tennessee Valley and Southern Appalachian region with high pressure at the surface in control. The feature will also bring with it a shot of cooler air.
255 AM EST Fri Nov 11 2016 A dry cold front will push southward through the area today.
1240 AM EST Fri Nov 11 2016 A mostly dry cold front crosses Friday, with very dry and much cooler air for the weekend.
302 AM CST Fri Nov 11 2016 (Today) Cold front as of 0800 UTC is currently aligned along a KSGF>>KUUV>>K1H2 line and will push through far southeastern portions of the CWA around daybreak. expect cooler conditions along with a partly cloudy to mostly clear sky. expect a chilly night across the bi-state area with lows in the low to mid 30s. While some areas will likely bottom out near or even slightly below the freezing mark. elected to not issue a freeze warning since a brief dip of temperatures to near freezing should only have minimal impacts.
337 AM CST Fri Nov 11 2016 A cold front will move through dry early this morning, followed by high pressure for the rest of the weekend.
219 AM MST Fri Nov 11 2016 Latest upper air analysis shows the cut-off low nearly stationary over Northern Mexico with a ridge arching over the Intermountain West. At the surface a cold front was over the Northern Plains accompanying a subtle upper level short wave trough southward. Behind the trough winds had turned to the north and were breezy at times. Tonight the cold front will move through the area. Highs will be 15-20 degrees cooler than today.
1230 AM EST Fri Nov 11 2016 A cold front moves across the Tri-State this morning.
The cool northerly flow across the Northland will gradually subside, and the cooler air will shift to the east. The sunny skies and warmer air moving into the Northland should help temperatures climb to the low to middle 40s.
345 AM CST Fri Nov 11 2016 Cold front now moving through the area as broad upper trough continues to push through eastern Canada this morning. The passage of this feature will set the stage for a cooler. will lead to a chilly overnight period with below freezing temperatures likely from the Missouri River north to the Iowa and Nebraska state lines.
410 AM EST Fri Nov 11 2016 The cold front moved across the Ohio border shortly after midnight, at least in terms of the wind shift, while the colder air gains traction southbound from northern Lower Michigan during the early morning.
High pressure at the surface and aloft have brought another sunny day to the state. Cooler northerly winds have prevailed this afternoon, but temperatures still made it to the lower 70s in a couple spots. Cooler temperatures are expected to continue through tomorrow as northerly flow brings more air from the northern plains this evening. Morning temperatures will drop to the lower 30s, then afternoon temperatures should rise back to the mid and upper 50s. Upper level ridging will be over the state as the upper low shifts to the south.
217 AM CST Fri Nov 11 2016 A dry cold frontal boundary will move south across the region today with high temperatures forecast to climb into the mid 70s.
The low just south and southeast of Douglas is beginning to fill a bit as the larger scale regional ridge phases across from the west. Skies will remain clear/mostly clear at TUS/OLS although some mid clouds could make their way into DUG later tonight given the proximity of an upper low.
227 AM EST Fri Nov 11 2016 A dry cold front will move across the area tonight, bringing the coldest air of the season by this weekend.
Little if any convection developed in the high plains as a warm elevated mixed layer with 700h temps of plus 18-20c kept the mid level cap firmly in place. Low level moisture transport does veer out some to the northeast towards sunrise, and moves into an area along and just east of I-135 that is a little cooler aloft (700h around +12-13), which may lead to an isolated shower/storm developing just after sunrise. Ketcham Anticipating isolated to widely scattered thunderstorms to form along the lee trough near the KS/CO border this afternoon, on southern fringe of large scale forcing associated with strong northwest CONUS upper trough. Warm and windy weather Monday, as a cold front approaches from the northwest.
Conditions will still be breezy this evening with relative humidities below 15 percent ahead of an approaching cold front. Added UTZ027 to the wind advisory in effect until 8 pm this evening as wind gusts are already exceeding criteria at Bryson Canyon with gusts in the low 50s. An unseasonably strong Low Pressure system was working through the Pacific NW today, then through the northern Rockies tonight. Its dry cold front will work through NE Utah before sunset, to near the I-70 corridor around midnight and into NW New Mexico by Monday morning. Breezy conditions continue on Monday especially north near the strongest pressure gradient, and south in the vicinity of the cold front.
754 PM EDT SUN JUL 10 2016 High pressure will remain in control of the weather tonight into Monday with dry conditions and moderating temperatures. Lows tonight should drop into the lower 60s.
