1140 AM CST Thu Feb 23 2017 High pressure will continue to build into the area today with widespread VFR conditions expected. A cold front will move into the area late tonight or early Friday. Cold front will move into the area late tonight or early Friday. Anyway, pressure gradient over the area will increase today, as high pressure over the Tennessee Valley slowly moves eastward, and low pressure deepens out in the plains, and drags a cold front toward the region. Humidity will decrease rapidly behind the front, as high pressure moves into the region.
thin layer of gulf moisture invoke cold front brings mostly mvfr cloud decks into area.
320 PM CST Thu Feb 23 2017 The main concern for the forecast period will be in the short term as a cold front passes through tomorrow evening. GFS does try to produce some activity with the prefrontal trough but more likely, the front will be needed to trigger activity.
A cold front will sweep across the area overnight bringing temperatures back to near or even slightly below normal for the next couple days. Fire danger will remain a concern Friday despite the cooler temperatures due to breezy west to northwest winds.
Moisture will continue to wrap around a center of low pressure, which is north of Pocatello/west of Idaho Falls this afternoon.
1236 PM EST Thu Feb 23 2017 Low pressure centered in the Bahamas will be moving farther off the Southeast Coast Friday.
1257 PM EST Fri Dec 2 2016 Flow around a large low pressure system to the northeast will keep cool and mainly cloudy conditions across the region today. High pressure will gradually build into the area on Saturday.
1109 AM EST Fri Dec 2 2016 Another quiet day across the eastern Tennessee Valley and Southern Appalachians, with high pressure promoting sunny and dry conditions.

Breezy conditions can be expected up in the higher hills of the Bay Area Friday morning. Meanwhile, increased northerly winds over the North Bay and around the San Francisco Bay kept temperatures slightly warmer, generally in the 40s to low 50s right along the bay and over the city. Breezy to locally gusty winds will continue over the northern portion of the region through the afternoon and early evening with the strongest winds in the higher elevations. As a result, temperatures are trending warmer across the northern area by 4 to 8 degrees compared to yesterday at this time, while locations in the calmer wind areas are running cooler by as many as 11 degrees, with readings in the upper 30s and 40s. Dew point temperatures are much cooler across the board with readings in the upper 20s to the upper 30s.
208 PM EST Fri Dec 2 2016 Cooler high pressure this weekend.
1131 AM CST Fri Dec 2 2016 Weak shear axis/short wave trough helping to bring some flurries to the region this morning. There will be a band of warm advection mid clouds, but with a dry/warming subcloud layer the low pops Saturday are more than likely to be just some flurries.
346 PM EST Fri Dec 2 2016 Weak front has moved south into the Keys this afternoon with high pressure building with drier air moving into the region. North to northeast flow returns with gradient strengthening as high pressure continues to build over South Florida. During the weekend, ridge will gradually drift east into the Atlantic waters returning east to southeast wind later in the weekend across S Florida. Ridge will keep us under drier conditions for the most part with no significant rainfall expected. Models continue to show an upper trough digging southeast along the west coast into the Desert Southwest this weekend and strengthens as it moves across the Central Plains.
343 PM CST Fri Dec 2 2016 It was mostly sunny and seasonably cool across the Mid-State this afternoon, as a high pressure area nosed in from the Central Plains and Middle Mississippi Valley. Temperatures across the area at 3 pm ranged from the lower 50s along the Cumberland Plateau, to the middle 50s to near 60 degrees elsewhere. Satellite pics show high and mid clouds racing to get into Middle Tennessee from the southwest, ahead of an upper level low pressure area over the Desert Southwest. As closed upper low migrates across northern Mexico and southern Texas over the weekend, Middle Tennessee will find itself in a moist isentropic pattern, with rain developing from the southwest Saturday and Saturday night.
High pressure to the north will build toward the east, with low level flow veering slightly toward the northeast overnight. Overnight mins expected to be much cooler over the northern interior versus southern coastal sections. High pressure slides east from the Midwest, with low level winds veering more ENE daytime as it does so.
250 PM EST Fri Dec 2 2016 High pressure continues over the area but will be weaken and push east as next frontal system nears the region.
400 PM CST Fri Dec 2 2016 (Tonight and Saturday) Rain has developed across a large part of the area as a deep upper trough located across Baja approaches West Central Texas. As the cold air continues to fill into the upper trough, both isentropic lift and lift associated with the upper trough will continue to increase through tonight and Saturday, resulting in good chances for rain.
320 PM CST Fri Dec 2 2016 The Northland's light northwest flow will continue into tonight, especially aloft, while the axis of a subtle ridge of high pressure shifts into Northland from the west. There are low chances of very light snow and patchy freezing drizzle across small portions of the South Shore, mainly along west/north side of the Bayfield Peninsula, due to the cold flow over Lake Superior. Light, southerly return flow will develop Saturday in the wake of the passing ridge of high pressure.
A weak disturbance will move through a ridge of high pressure over the pacnw today with clouds and showers accompanying the system into tonight.
associated with the subtropical jet ahead of the digging upper level trough now entering Nrn Baja/NW old MX.
1241 PM EST Fri Dec 2 2016 Low pressure across the Great Lakes will keep clouds and near seasonal temperatures across the area into the weekend. Mid level trough over eastern Canada will continue to transition east through tonight, with weak cold advection across the region. Southwest flow today will keep bulk of lake enhanced snow showers or sprinkles well north, with only scattered snow showers north of I-80 and in the ridges. Flow will turn slightly more to the northwest tonight, which will allow for a bit more coverage of snow showers into the ridges and I-80 corridor, but only a light accumulation if any.
1152 AM CST Fri Dec 2 2016 A dry airmass was still overhead Southeast Texas at 17Z, along with a coastal trough over South Texas and a warm frontal boundary developing over the offshore Gulf waters. The higher resolution models are indicating that showers and thunderstorms will likely hold off for a few hours longer than the previous forecast. from the near 2 inch pwat air mass off the southern Texas coastline being pumped in on moderate mid- level flow to a slowly approaching cold frontal boundary over northern Texas that will provide ample mid-level focus for interior precipitation. A better organized coastal trough and associated warm frontal boundary moving north from the Coastal Bend will increase areawide precipitation this evening through the overnight hours.
41 Dry conditions are expected today and tonight with relative humidity values falling into the lower 30s this afternoon. One more day of dry weather today and tonight as high pressure will remain over us before sliding to the east on Saturday.
345 PM EST Fri Dec 2 2016 High pressure will prevail through Saturday.
1217 PM EST Fri Dec 2 2016 Low pressure across the Great Lakes will keep clouds and near seasonal temperatures across the area into the weekend. Mid level trough over eastern Canada will continue to transition east through tonight, with weak cold advection across the region. Southwest flow today will keep bulk of lake enhanced snow showers or sprinkles well north, with only scattered snow showers north of I-80 and in the ridges. Flow will turn slightly more to the northwest tonight, which will allow for a bit more coverage of snow showers into the ridges and I-80 corridor, but only a light accumulation if any.
A weak surface trof drifted south across the CWA this morning. This trof was associated with a low pressure located northwest of the Great Lakes. Zonal to slightly NW flow at H5 will aid in advecting in slightly drier and cooler air today as a sfc trof slowly drifts south. Temps will range from the mid 30s to the low 40s across the CWA. fair early then increasing clouds and seasonably cold, with high pressure overhead. Lows should be mostly in the lower to middle 30s and with our warm ground should limit snow accumulations to mostly the grassy surfaces, especially along and south of highway 34.
405 PM EST Fri Dec 2 2016 High pressure will build into the area Saturday and move off to the east Saturday night.
225 PM CST Fri Dec 2 2016 High pressure will continue to remain anchored over the Ohio Valley region tonight into Saturday, keeping things rain-free and seasonably cool. Though temperatures may fall into the mid 30s in some locations, it now appears freezing levels will remain too high for any light snow to make it down to the surface.
348 PM EST Fri Dec 2 2016 An upper trough will move southeast from Canada overnight, and will bring a chance of rain and snow showers.
444 PM EST Fri Dec 2 2016 A trof of low pressure will cross the region through Saturday.
1132 AM CST Fri Dec 2 2016 Latest water vapor satellite imagery shows upper level closed low over eastern Canada and northeast United States and longwave trough over the Rocky Mountains. as surface/upper level ridge axis builds into eastern Minnesota and western Wisconsin Saturday morning. High temperatures today are expected to remain nearly steady in the lower to middle 30s.
Upper level ridging and partial clearing will allow for mild temperatures today.
248 PM EST Fri Dec 2 2016 High pressure will be reinforced from the northwest and as a result the weather will remain dry through Saturday.
258 PM CST Fri Dec 2 2016 Upper low currently situated near the CA Baja region. Southwesterly flow aloft to strengthen ahead of the low.
Accumulations of a couple inches remain possible across the higher terrain west of I-25, with an inch or less likely east of the corridor. An upper disturbance over southern Idaho is forecast to drop south into Arizona and combine with an upper low. the upper low over Arizona will continue to drop south into northern Mexico, while the disturbance in the southwest flow out of New Mexico lifts across our far southeastern Plains into western Kansas.
324 PM EST Fri Dec 2 2016 Quiet weather continues across the region this afternoon, with high pressure in control. Thus, a slightly cooler day is expected with highs peaking in the upper 40s to lower 50s. Wind speeds will be light, but a few erratic higher gusts will be possible along the higher terrain.
150 PM MST Fri Dec 2 2016 Strong surface pressure gradients between high pressure over the Great Basin and and low pressure over northern Mexico will continue to produce strong and gusty northerly winds across a large part of southeast California and the Colorado River Valley tonight and Saturday.
1130 AM EST Fri Dec 2 2016 Low pressure will gradually exit into the maritimes by tonight.
It does still appear it may cool just enough to support the risk for a wintry mix and generally light accumulations of snow, sleet and freezing rain across the extreme southwest Texas Panhandle into the northwest South Plains late this evening into Saturday morning. However, another shot of lift is expected to pivot this way in the diffluent flow ahead of the gathering upper low now sinking toward the Gulf of California.
A weak disturbance will bring a chance of light freezing rain/snow late tonight into early Saturday for mainly the northern zones.
155 PM MST Fri Dec 2 2016 Upper trough is over the western and north central CONUS, and an area of low clouds continues to cover much of the northern plains. With high pressure over the region, winds are light and variable. Trough will cross the region Saturday, with increasing clouds and winds becoming more westerly.
Have kept patchy freezing drizzle going for the early morning hours over the southwest and south central as some very light freezing drizzle fell in Bismarck and webcam up by Garrison Dam had a few spots on it. Still kept some patchy fog over the southwest in the higher terrain. Upper level analysis place low over western Quebec/eastern Ontario with trough stretching from the upper midwest towards the Great Basin. Cool and moist low levels over our area has lead to persistant low cloud cover with some spots of freezing drizzle, though this has tapered off over the last few hours. A little clearing may develop over the southwest/south central overnight ahead an an approaching trough. Aforementioned trough quickly pushes through the area bringing low snow chances for Saturday.
Tonight Through Saturday High pressure will be over western and central Wyoming tonight with cold air in the valleys and basins with patchy fog expected. A Pacific low pressure trough will dig southeast from the Idaho panhandle and northwest Wyoming Saturday with snow moving into the northwest spreading south and east through the day.
1102 AM CST Fri Dec 2 2016 Weak shear axis/short wave trough helping to bring some flurries to the region this morning. There will be a band of warm advection mid clouds, but with a dry/warming subcloud layer the low pops Saturday are more than likely to be just some flurries.
130 PM EST Fri Dec 2 2016 No change to ongoing forecast as High Pressure builds NW of the region over the SE U. High pressure will be Northeast of the region Saturday night.
238 PM EST Fri Dec 2 2016 A weakened front/trough is stretched across the Keys service area this afternoon. The echoes on KBYX radar west and northwest of the Lower Keys are chaff. Temperatures along the island chain have cracked the 80 degree mark where cloud breaks have been more prominent, and are in the upper 70s in the Lower Keys. The local airmass does not change significantly, and a low level remnant of the trough may ease back across the local area as easterly breezes deepen overnight.
Upper trough currently digging into the desert southwest is expected to close off tomorrow morning, slowing its forward progression as it nearly becomes cut off from the overall flow. Flow around this low will force a warm front toward the northern gulf coast.
Low pressure will continue to move across eastern Cananda and Maine as high pressure approaches from the west. The high will move just south of the region on Saturday with mid level ridging overhead.
252 PM MST Fri Dec 2 2016 Light snow showers have been falling from Laramie to Cheyenne over the past few hours ahead of a weak upper trough that is positioned across western WY.
1244 PM EST Fri Dec 2 2016 High pressure will prevail through Saturday.
Light rain will also increase overnight through Sat morning w/ the higher rainfall rates expected for southern sites.
313 PM CDT WED JUN 8 2016 A strong ridge to the west will keep the skies mostly sunny for the next few days. Rain chances are minimal for the most part as a weak low pressure system in Southeast TX will keep the Gulf of Mexico cut off.
High pressure at the surface, rising heights aloft, and a relative lack of moisture will be the dominant weather features in the short term.
VFR is expected beneath an upper level high pressure ridge through midday Thursday. /issued 315 AM CDT WED JUN 8 2016/ High amplitude upper ridge is in firm control of the Western CONUS this morning though monsoonal moisture is doing its job of keeping the ridge a bit dirty just to our west. The ridge will slowly shift eastward today with perhaps only about a 10m H5 height increase. Thursday will be another quasi windy day (20mph on average) thanks to a surface lee trof.
316 PM CDT WED JUN 8 2016 Upper lvl ridging has taken a firm hold across the region. No changes to this persistence fcst thru rest of week with only subtle changes by wknd as ridge begins to break down and backdoor front begins knocking into AR. Dewpoints may sneak upwards in light south winds as ridge breaks down and sea breeze front as well begins to indroduce pops to area.
1257 PM CDT WED JUN 8 2016 High pressure dominates the Midwest this morning and warm temperatures and light and variable winds remain the rule. High pressure will dominate the weather across central Illinois today, providing mostly sunny skies and much lighter winds than have been noted in recent days. Despite cool early morning lows in the lower to middle 50s, dry airmass will heat efficiently today. Adjusting forecast soundings to an approximate mixing height of 800mb this afternoon yields high temperatures in the middle to upper 70s, which is a couple of degrees warmer than numeric guidance. As the high shifts east of the region, WAA will begin tonight.
143 PM EDT WED JUN 8 2016 Cool high pressure builds in today.
356 PM EDT WED JUN 8 2016 High pressure moving into the area this evening will provide mostly clear skies tonight.
324 PM CDT WED JUN 8 2016 High pressure centered over southern Illinois at early afternoon with the ridge axis to near Lake Charles. With the exception of lower Plaquemines Parish, all sites have warmed into the lower and middle 90s this afternoon. The Illinois high pressure will slide slowly eastward over the next couple of days, gradually turning the winds to onshore and returning moisture to the area.
301 PM PDT WED JUN 8 2016 Satellite imagery and upper-air analysis show large trough approaching the Pacific Northwest coast. Ridging over the NV region has suppressed Afternoon convection which is confined to the eastern one-third of the CWA and Jarbidge area with more localized instability found across southern ID. Eastward advancement of the trough and tightening pressure has caused winds to increase and back to WSW across the region. Instability axis has shifted to far eastern NV with some convection developing along ridge lines farther south near Eureka and across the Jarbidge region.
A cold front pushing through after 09/0200z will cause a wind shift late this evening. With current hot and relatively moist atmosphere will come the chance for strong thunderstorms in southwest flow ahead of low pressure which is currently spinning off the West Coast. A cold front is ex pected to shift across north central Idaho late this afternoon and into western Montana during the evening. The cold front will produce increasing winds, but also help enhance some of the prior discussed thunderstorms. A cooler air mass should cover the northern Rockies Thursday.
1229 PM CDT WED JUN 8 2016 Warmer temperatures and increasing south winds will return to Kansas for today.
(Issued 1036 AM CDT WED JUN 8 2016) This morning was cooler and much drier across the TN Valley with overnight lows cooling into the lower 50s! The same trend will continue through the rest of today as well! In the wake of the cold front, dewpoints are around 10 degrees lower today and water vapor satellite highlights dry air across the region as well. As high pressure continues to move into the region and the pressure gradient slacks, the gusts will diminish.
/ISSUED 327 PM CDT WED JUN 8 2016/ Upper level ridge of high pressure was shifting eastward into the Central United States this afternoon. helping temps this afternoon to warm into the upper 80s and lower 90s and dewpoints into the low to upper 60s over the CWA. The upper level ridge is expected to remain the dominate feature over the Plains into the weekend. while temps overnight become slightly warmer each night from dewpoints in the 60s/low 70s.
A large-scale upper level trough will be the main weather feature through the weekend. This will bring a period of cooler conditions to the Southwest Washington and Northwest Oregon, with daytime temperatures falling a little below normal values.
With current hot and relatively moist atmosphere will come the chance for strong thunderstorms in southwest flow ahead of low pressure which is currently spinning off the West Coast. A cold front is expected to shift across north central Idaho late this afternoon and into western Montana during the evening. The cold front will produce increasing winds, but also help enhance some of the prior discussed thunderstorms. A cooler air mass should cover the northern Rockies Thursday.
236 PM EDT WED JUN 8 2016 High pressure will maintain dry and cool weather through the day Thursday.
516 PM EDT WED JUN 8 2016 Cool high pressure through Thursday.
307 PM CDT WED JUN 8 2016 Messy pattern remains in place across sern TX with weakening mid level trough along the coast keeping mid and high level clouds in place. This feature will linger for another day or so before larger mid/upper level ridge begins to become more established across the srn plains. Although large scale ridging begins to take hold by the end of the week and into the weekend, the airmass will become quite moist with PWs increasing to around 2".
Ridge axis directly overhead today will be shifting east Thursday as a trough moves into the West Coast. Also, model soundings actually show some lowering of the marine lyr tonight despite the lowering heights but could be the case given the slight offshore trends and warming in the lower levels.
630 PM EDT WED JUN 8 2016 High pressure will build in from the west tonight and persist through the end of the week.
The new 12z model package is in good agreement showing the high centered over lower Michigan by sunrise with several hours of solid radiational cooling during the overnight prior. However, readings in the Thumb could already be in the lower 40s by the time enough coverage arrives there.
240 PM CDT WED JUN 8 2016 Some showers/storms that develop in the high plains this afternoon/evening may move into northwest OK early Thursday.
327 PM CDT WED JUN 8 2016 Upper level ridge of high pressure was shifting eastward into the Central United States this afternoon. helping temps this afternoon to warm into the upper 80s and lower 90s and dewpoints into the low to upper 60s over the CWA. The upper level ridge is expected to remain the dominate feature over the Plains into the weekend. while temps overnight become slightly warmer each night from dewpoints in the 60s/low 70s.
313 PM PDT WED JUN 8 2016 Cooling trend through this week as a trough approaches. Northern CA is sandwiched between weak high pressure to our southwest and an approaching trough to our northwest. This trough will continue the cooling trend we've had since our heat event last weekend.
300 PM EDT WED JUN 8 2016 Most of the short term period will feature dry and pleasant weather with light winds across eastern Kentucky as an area of high pressure remains in place across the region for the next couple of days. The rest of the valleys should only drop into the upper 40s, while the surrounding ridges see lows in the lower 50s. Highs on Thursday should be slightly warmer than today, with highs expected to max out around 80 across the area. Upper ridging across central North America will continue to be anchored by cyclonic flow on either side stretching from southern Canada into the northern U.
121 PM EDT WED JUN 8 2016 An upper level trough will move east of the area today. High pressure from the Mississippi Valley will move east across the area tonight through Thursday.
Mainly dry and warm conditions will continue through Thursday as high pressure shifts north and east over the southwestern US.
324 PM CDT WED JUN 8 2016 Deep ridging is currently moving across the northern Rockies this afternoon and will continue to cross into the northern and central Plains through the latter half of the work week.
1234 PM CDT WED JUN 8 2016 Aloft: The Wrn USA ridge will make steady/slow progress. The low-lvl jet will redevelop but the strongest WAA will be well NE of the fcst area. close to the better thermal packing along the warm front.
