Band of light rain showers is expected to develop ahead of a cold front moving through the region.
1033 AM EST Mon Nov 7 2016 High pressure will build over the area through Tuesday.
436 AM CST Mon Nov 7 2016 (Today and Tonight) An unsettled pattern will continue during the next 24 hours as an upper level trough remains over the area. Also, clouds will break up some this afternoon and allow some instability to take place across the eastern 1/2 of the area and combines with low level moisture, dewpoints in the lower to mid 60s.
Expect above average temperatures in the upper 70s to low 80s and variable cloud cover resulting from the upper low to the west and weak isentropic lift from low level easterly flow. Meanwhile, upper level ridging also continues today, but will begin to weaken and flatten out later today ahead of an upper level trough. With deep layer ridging in place, highs today will remain above average, around 5 degrees above normal at TLH.
In the middle and upper levels (700-200 mb,latest available satelitte imagery overlaid with model streamline analysis) as of 900 am depict a deepening longwave pattern over the Central CONUS, with a developing Upper low within a trough axis extending from the Prairie Provinces down to Oklahoma. Rest of the day and this evening, The strong 1030 mb plus ridge will remain anchored along the NE Seaboard down to the Mid Atlantic States working in tandem with the aforementioned ocean storm to create windy conditions across the islands and surrounding waters.
Most of the high resolution models keep rain chances out of the picture for most of the day. Weak isentropic upglide will develop Tuesday as a SW flow aloft overrides cooler NE sfc winds. The upglide weakens Wed/Thu as the upper low over W TX retrogrades westward. SE TX will lie in a subsident zone of the jet so forcing/lift will be limited and rain chances should be slight to nil with the higher chances over the Gulf.
1054 AM EST Fri Feb 3 2017 A cold front just northwest of our area will inch towards southeast Georgia today, eventually moving into that area later this afternoon and then into northeast Florida this evening. The exception will be across well inland areas of southeast Georgia, where temps will be a little lower as clouds and cooler air push into that region with the front this afternoon. An inverted coastal trough will bring a low chance of light rain showers to the immediate coastal areas on saturday. Saturday will be much cooler across the area with cloudy skies expected due to the onshore flow pushing marine stratocu field inland. Cold front will move south across the waters tonight.
VFR ceilings will prevail this evening and overnight as the cold front begins to lift northward.
This high will dominate today's weather, with skies remaining mostly sunny and temperatures staying on the chilly side. One of the highlights will be the brief shot of warmer temperatures moving in on Saturday as mild air surges northward ahead of an approaching cold front. Models still show a cold front moving across the region Saturday afternoon.
911 AM EST Fri Feb 3 2017 High pressure will slowly build into the region through the end of the week.
but North wind around 10 mph will advect at least slightly cooler air into the region. Skies should clear today as high pressure shifts over the Mississippi River Valley. Highs today will be mainly in the low to middle 40s with lows tonight in the low to middle 20s. A warmer.
941 AM EST Fri Feb 3 2017 Aviation section updated High pressure building into the northern plains will move east across Indiana late tonight.
850 AM EST Fri Feb 3 2017 One short wave trough approaching from the Gulf while another exits NE FL will have little impact. A cold front across far north FL with weak high pressure to the south will slowly drift south. The high is rather relaxed and will allow winds to shift to westerly in an afternoon sea breeze. Relaxed high pressure continuing across the waters today will allow a sea breeze to shift winds onshore in the afternoon. A cold front eases into then exits the area overnight as high pressure builds in behind it.
539 AM EST Fri Feb 3 2017 Large high pressure over the Plains states this morning will move east and reach the Middle Atlantic region Saturday afternoon.
Less than ideal aviation conditions are occurring right now in the wake of the recent passage of a cold front. /issued 349 AM CST Fri Feb 3 2017/ SHORT TERM (Today through Saturday): A cold front has passed through the entire inland portion of the BRO CWFA and most of the adjacent coastal waters per the most recent surface analysis and the current surface observations. As the inverted trough moves onshore and pushes west through Deep South Texas and the Rio Grande Valley on Saturday, the chance of scattered patches of rain will persist. The passage of the aforementioned cold front will hold daytime high and overnight low temperatures at near normal levels for the period.
Drier air continues to feed into the region behind a cold front that has moved well south of the area. /26/ Prior discussion below: The slow moving cold front that pushed through the region yesterday has finally cleared the JAN CWA. A drier, cooler cP air mass will continue to filter into the region throughout the day. Radiational cooling will help lows fall below freezing in the areas north and along I-20 and in the mid 30s elsewhere.
527 AM CST Fri Feb 3 2017 A small potential for flurries this morning, cool this afternoon, then warmer for the weekend, are the highlights of this forecast. Sunshine and light winds should make rather cool temperatures feel a little warmer than the upper 20s or lower 30s highs. Warming really takes hold on Saturday as south then southwest low level flow ahead of low pressure moving east through South Dakota drags warmer airmass into the region.
431 AM CST Fri Feb 3 2017 A bit warmer today, but still running 5 to 10 degrees below normal for early February.
554 AM CST Fri Feb 3 2017 A ridge of high pressure will translate south and east over the Middle Mississippi Valley area today.
901 AM EST Fri Feb 3 2017 Cooler than average temperatures will continue into the weekend.
Fast zonal flow overspreads much of the central and eastern CONUS this morning with weak ridging extending from Mexico into the Southern Rockies. Meanwhile, at the surface, a strong cold high pressure center is located over the Northern Plains. A weak trough extends along a cold front shifting southward across the southeastern U. An approaching cold front will allow winds to shift onshore early this afternoon as high pressure moves east into the western Atlantic. The cold front will make its way through the northern Florida peninsula tonight, but as it weakens, it will be a dry frontal passage. For Saturday, strong high pressure will become established along the Mid-Atlantic coast. Slightly cooler air will filter into the region, though temperatures will generally remain near or just above normal for early February.
Meanwhile, the mean upper trough over eastern North America will support a period of below normal temperatures for a change.
935 AM EST Fri Feb 3 2017 Weak ridge axis over central FL accompanied by a dry/stable airmass. Near full sun and a weak sfc/low lvl pgrad will allow a sea breeze to dvlp by early/mid aftn that will keep coastal max temps a few degs cooler than the interior. Light/variable winds over the lcl Atlc as a frontal trof extending from the nrn GOMex to the Carolina Coast as disrupted the lcl pgrad.
529 AM EST Fri Feb 3 2017 Cooler than average temperatures will continue into the weekend.
Today through tonight: The slow moving cold front that pushed through the region yesterday has finally cleared the JAN CWA. A drier, cooler cP air mass will continue to filter into the region throughout the day. Radiational cooling will help lows fall below freezing in the areas north and along I-20 and in the mid 30s elsewhere.
/issued 418 AM CST Fri Feb 3 2017/ Cool high pressure, centered over the central Plains, will move east, bringing southerly winds back to Oklahoma and north Texas by Saturday morning. This will, in turn, bring warmer weather into the region.
1027 AM EST Fri Feb 3 2017 The cold front is now along the coastline with colder and drier air advecting into the Southern Appalchians.

Forecast soundings show increasing llvl saturation up to about 700mb complements of S/SW flow overrunning the cooler airmass the the surface.
Otherwise, expect steady west winds today, with high temperatures just a little warmer than yesterday. Axis of high pressure propagates across the region with return flow setting up overnight, and westerly winds become southerly.
526 AM CST Fri Feb 3 2017 Today will be mostly sunny and dry as a large area of high pressure across the Dakotas moves southeastward and into the mid Mississippi River Valley. Temperatures will be 3 to 5 degrees warmer than yesterday, topping out in the upper teens to lower 20s. Then, temperatures overnight are likely to hold steady or perhaps rise slowly as clouds increase from southwest to northeast ahead of the next low pressure system.
Stratus deck covers all of South Texas with ceilings in the 1500-2000 feet range behind the cold front that is well south of the area. Cold front has pushed through the offshore waters down into Deep South Texas early this morning. High pressure will continue to build into the region today reinforcing the cooler air mass over South Texas. This reinforcing shot of cooler air has moved into the Victoria Crossroads and extends into the Hill Country at 09Z. Coastal trough will move toward the coast on Saturday. High pressure will continue to build into the marine areas today with northeast winds expected to reach SCA levels this afternoon over the Gulf waters.
Went with freezing temperatures overnight across our northern and northeast zones as the 850mb trough axis could shift south of the I-20 corridor this evening before returning back to the north and east overnight with our northern and northeastern zones likely seeing the least insulation from cloud cover.
643 AM EST Fri Feb 3 2017 High pressure will slowly build into the region through the end of the week.
Went ahead and upgraded the High Wind Watch across the wind prone areas. Appears the Sierra Madre Range will see the highest snowfall amounts of 4-6 inches.
Additional light to moderate scattered showers continue to track northeast across central California this morning ahead of an approaching Pacific cold frontal system. After tonight, the weekend will be mainly dry, as the low pressure system moves away to the east.
Expect variable mid and high level cloud cover today as a weakening short wave trough moves through the Great Basin.
/Issued 431 AM CST Fri Feb 3 2017/ A bit warmer today, but still running 5 to 10 degrees below normal for early February.
The 7 am regional surface analysis showed a cold front from central SC, through central GA, through southwest AL, and into the northwest Gulf of Mexico. Upper air data showed generally westerly flow over the Southeast, with a few, weak short wave troughs translating quickly eastward. The surface cold front will move slowly southeastward through our forecast area today and this evening, bringing mostly cloudy skies and a few light showers. High temperatures will be held to the lower 60s north of Albany and Dothan (due to cloudy skies and weak cold advection), but will reach the mid 70s from Tallahassee south and eastward, where there will be a longer period of sun.
614 AM EST Fri Feb 3 2017 High pressure with quiet and cold conditions into the weekend.
1044 AM EST Fri Feb 3 2017 Currently - A pressure ridge stretching across the Florida Peninsula is maintaining light to gentle north to northeast breezes across the Keys. Temperatures range in the low to mid 70s with dew points near 70. A weak pressure ridge will remain over the Florida Peninsula.
518 AM CST Fri Feb 3 2017 Very little change in the forecast through Saturday morning as high pressure that was centered across Nebraska early this morning, moves southeast and keeps the Upper Midwest dry. Winds will gradually shift to the southwest, south and southeast as the center of the high moves over the Ohio Valley.
Showers are ongoing along the front this morning across SC/GA/AL where lee troughing has further increased low-level convergence.
523 AM CST Fri Feb 3 2017 Axis of high pressure propagates across the region with return flow setting up overnight, and westerly winds become southerly.
319 AM PST Fri Feb 3 2017 The tail end of a trough will move across the area today through tonight, leading to some light rainfall across especially Orange and San Bernardino Counties.
Upper low expected to be positioned off the Pacific Northwest through the weekend. Today expected to be generally dry with the pattern shifting with ridge sliding across the state.
418 AM CST Fri Feb 3 2017 Cool high pressure, centered over the central Plains, will move east, bringing southerly winds back to Oklahoma and north Texas by Saturday morning. This will, in turn, bring warmer weather into the region.
Mid-level troughiness along the Texas coastline will generate isolated showers and thunderstorms over Deep South Texas and the Rio Grande Valley today and tonight, and coverage is still expected to be too limited to include it in the current suite of TAFs. /issued 341 AM CDT TUE JUN 7 2016/ SHORT TERM (Today through Wednesday): Elongated 500 mb low pressure along the entire coastline of Texas will gradually close off and become centered over Deep South Texas and the Rio Grande Valley during the forecast period.
High pressure moves into the region and should keep the area rain free for the rest of the week. Expect daily highs reaching the lower 90s for most of the forecast area for the rest of the week. High pressure will eventually transition to the east over the weekend and allow moisture to return to the area from the Gulf of Mexico.
623 AM CDT TUE JUN 7 2016 Will be a very pleasant day today with high pressure in control. Tonight, the high pressure system will move off to the east bringing our low level winds around to the southeast. Southerly flow increases across the region on Wednesday as surface ridging slides off to the east. This will result in a warmer day with highs generally lower to mid 80s. It will also be a milder night with lows in the lower 60s.
Some moderation in temperatures can be expected today and Wednesday as high pressure aloft weakens.
/Issued 315 AM PDT TUE JUN 7 2016/ Dry conditions and above average temperatures will continue through midweek followed by cooler temperatures by the weekend.
Much cooler temperatures are expected tonight with lower 50s in the eastern Ozarks. A high amplitude upper ridge will build over the nation's midsection, bringing summertime conditions to the Ozarks.
An increase in cloud cover is expected this afternoon for the I-35 TAF sites as the weak upper level low inches back to the west, but cloud decks will stay above 5000 feet. The mid and upper level trough off the Texas coast will close off again over Deep South Texas and northern Mexico today into Wednesday. As a result, the low and mid level flow across the southern CWA veers more easterly and the pool of moisture across the Coastal Plains is advected farther west through southern areas Today and Wednesday.
A strong upper low will move east across the great lakes and St. Lawrence valley producing cooler than normal weather through Wednesday night. dry weather will be the rule through Wednesday night as high pressure over the northern plains builds east into our region.
Temps this morning were a few degrees cooler than yesterday and could feel the lower dewpoints already as well. Current temps across the TN Valley are in the lower 80s already with plentiful sunshine. The cold front is still to our NW and will move across the forecast area this afternoon. Therefore, adjusted the highs up a degree or so and did the same with today's dewpoints.
924 AM MDT TUE JUN 7 2016 Fine line moving northeast through the area this morning is the warm front. High temperatures will range from the low 80s in the Hill City, Norton and McCook areas to the mid 80s to around 90 from Burlington to Leoti. This is fairly close to the warmer mav guidance.
High pressure aloft will strengthen once again across the Great Basin Wednesday, then shift east as a storm system enters the Pacific Northwest late in the week. A weakening low pressure center is making its way across the forecast area this morning. The wave will move out of the area tonight, with high pressure quickly rebounding for Wednesday. Conditions will be generally quiet, but a few showers are possible over the higher terrain in the afternoon.
636 AM CDT TUE JUN 7 2016 Noticeably less humid air overspreading the region this morning following the passage of last night's cold front. early morning water vapor showing a large ridge of high pressure building across the northern Rockies. aforementioned high pressure expected to slide off to our east as upper ridging translates east from the Rockies. This will allow for the return of southerly flow and the return of more humid air as a weak warm front lifts through the region. Models show some QPF directly to our north and west as the low-level jet impinges upon the boundary.
/ISSUED 344 AM CDT TUE JUN 7 2016/ Evening/overnight convection across the high plains will continue moving southeast across the Texas Panhandle early this morning. This activity will weaken as it moves into drier and more subsident air which currently resides across the Low Rolling Plains.
The short term starts off with high pressure over the area and cool temps this morning, with even some 30s across parts of northern Minnesota. The high drifts eastward today, but will provide fair skies and light winds. Meanwhile, an upper level ridge continues to drift eastward from the western states. With the high pressure drifting east across northern MN tonight, Beltrami and Lake of the Woods counties could get cool once again (almost to frost temps).
Once this frontal boundary moves through the state today, dew points will drop off considerably and temperatures will be noticeably cooler. While latest guidance shows a degree or two warmer for Wednesday than what we've seen the last couple of nights, we should still end up 2 to 4 degrees below normal on Wednesday.
High pressure will build in from the west this afternoon and persist through late in the week. Drier air filtering into the area will gradually scour out the low stratus and bring mostly sunny skies to most areas this afternoon. Tonight: A weak cold front will push offshore after midnight. Lows will range from the mid 60s well inland to the lower 70s at the beaches.
Have trended slightly warmer for today based on upstream temps yesterday as well as the cool performance of MOS yesterday. Location of activity still hard to pin down as it will be dependent on where warm front sets up.
High pressure will take control on Wednesday with dry weather expected through the weekend. Temperatures this afternoon will be around 90 with overnight lows in the lower to middle 60s.

723 AM EDT TUE JUN 7 2016 Cooler weather is forecast through the middle of the week before we warm back above normal by week's end. Upper-level trough axis will shift quickly to our east Wednesday leading to a drying and clearing trend through the afternoon. Deep mixing Wednesday morning means gusty winds will be common as the trough passes, but these should lessen by afternoon as the pressure gradient loosens.
1109 AM CDT TUE JUN 7 2016 Slightly cooler and much drier air working into the northern parts of the Mid-South this morning behind the cold front. High pressure has resulted in clear skies throughout the Mid- South tonight. Temperatures today will be 1-2 degrees cooler than yesterday as the weak front pulls slightly cooler air into the region. A light jacket may even be utilized in locations near the Tennessee River where temperatures may fall to the low to mid 50s Tuesday and Wednesday night. A steep, stagnant upper level ridge will become centered over the Central U.
640 AM CDT TUE JUN 7 2016 A LONGER WAVE LENGTH UPPER TROUGH ACROSS THE EASTERN US WILL SLOWLY TRANSLATE EAST OFF THE ATLANTIC COAST WHILE AN UPPER LEVEL RIDGE ACROSS THE WESTERN US MOVES EAST ACROSS INTO THE PLAINS. ENJOY THE SLIGHTLY COOLER TEMPERATURES TODAY WITH HIGHS IN THE MID 80S ACROSS THE WESTERN CWA AND LOWER 80S ACROSS THE EASTERN HALF THE CWA.
9 inches, whereas further inland they have dropped back into the low-1 inch range. The drying over our western zones looks relatively short- lived as all guidance pushes the higher moisture airmass towards the Rio Grande Plains by late this afternoon/early evening.
1158 AM CDT TUE JUN 7 2016 The forecast is on track with high pressure in control of the weather over the ArkLaMiss and temperatures expected to rise into the lower 90s this afternoon. On Wednesday mid to upper ridging will build across the region from the Plains. Nightly lows will range from the lower to middle 60s. This was especially the case for Wednesday night with the high clouds around.
expect cigs to scatter out as high pressure builds in from the west this evening.
This will set the stage for a less active afternoon in the convection department, although still anticipate at least isolated coverage of afternoon and evening thunderstorms, favored over the higher terrain. Dry weather then expected for the overnight hours as upper level ridge shifts east into the plains. Filling in behind the exiting ridge will be a weak Pacific system that is expected to set up shop across our area by midday Wednesday.
/issued 353 AM CDT TUE JUN 7 2016/ Upper ridge centered west of Baja this morning with ridge axis running up through Idaho. The ridge axis will shift east as high pressure builds in from the west. There has been some storms overnight from the Panhandle back across the higher elevations of NM. By the weekend storm chances increase but mainly over the higher elevations out west.
418 AM PDT TUE JUN 7 2016 Cooling through the end of the week as high pressure weakens. The strong upper ridge covering the West will only shift a little further to the east today.
/issued 330 AM CDT TUE JUN 7 2016/ (Today and Tonight) The gradual warming trend under upper level ridging will continue today and tonight.
The Medford CWA is currently in between an offshore long wave trough and a broad ridge over the Western U. This low.
As an upper-level trough gradually approaches northwest California, temperatures will cool to near seasonal values area- wide. This trough may also produce a few showers north of a Eureka to Weaverville line for the end of the week. An upper-level ridge axis will be parked overhead, allowing tempertures to spike to well above normals for the interior valleys, where readings should top out in the 90 to 100 degree range.
1004 AM CDT TUE JUN 7 2016 Cold front continues crossing Middle Tennessee this morning and stretches roughly from Lobelville to Crossville at this hour. Much drier air with dewpoints in the lower to middle 50s will spread southward behind the front through the day. Winds will pick up out of the northwest this morning as a cold front passes through the region.
Northwest flow will usher in dry air today with a cold front pushing through this evening bringing very pleasant conditions to the region. 88 Wednesday through Tuesday A convergent pattern will set in as an upper ridge anchors itself over the central plains.
