1229 PM 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.
134 PM CDT TUE JUN 7 2016 There isn't much to talk about during the short term forecast period, as high pressure settles in and fosters dry weather with mostly clear skies and relatively light winds. Lows tonight will dip into the lower 40s to lower 50s, with patchy fog possible in east central MN and west central WI.
High pressure was building into the region from the Northern Plains. to the lower/middle 50s elsewhere. High pressure will slide across the region today, providing mostly sunny skies. Otherwise, plan on cooler than normal highs in the 60s. High pressure directly overhead tonight with nearly calm winds and mostly clear skies expected. This will lead to respectable amount of radiational cooling which will lead to chilly overnight lows in the lower 40s across central WI and middle/upper 40s elsewhere. High pressure will begin sliding off to the east on Wednesday for onset of warm air advection. Under mostly sunny skies, look for highs in the upper 60s northeast of I-94, and in the lower/middle 70s elsewhere.
201 PM EDT TUE JUN 7 2016 Multiple disturbances, rotating around a large area of low pressure centered in eastern Canada, will keep our weather cool and unsettled through the midweek period. This activity was forming in advance of another trough which existed from the surface through middle troposphere. With this trough cold air advection will increase through the day as it works eastward across NY and PA from 850 mb and above. Sharp upper trough and very cold air aloft, to the point of 1000-500mb thickness reaching around 540 decameters, will pass directly over our region Wednesday. Wednesday night will continue to be breezy with considerable cloud cover over central NY and some scattered showers due to the lingering upper trough and moisture enhancement from the lake.
A low pressure system will bring cooler temperatures over the weekend.
349 PM CDT TUE JUN 7 2016 A cold front is banked against the Rockies today, which allowed a cooler day in the upper 70s to around 80 for highs. The NAM advertises near 1500 J/kg of MUCAPE along the axis, which may be a bit on the high side. As the upper ridge begins to dominate our weather while we will be squarely in the warm sector, expect warmer temperatures for highs in the 80s, but chance of precip will be suppressed as the instability axis will be long gone.
336 PM EDT TUE JUN 7 2016 Skies are expected to clear overnight as high pressure builds into the region.
A gradual cooling trend will take place through this weekend as high pressure is slowly displaced and as moisture increases later in the week.
350 PM CDT TUE JUN 7 2016 Cold front has moved south of Middle Tennessee this afternoon with much drier air consisting of dewpoints in the 50s and even upper 40s now in place across the area. This dry airmass will allow for much cooler temperatures the next 2 days, with lows in the 50s tonight and Wednesday night, and highs only in the mid 70s to mid 80s on Wednesday.
354 PM EDT TUE JUN 7 2016 A cold front crossing through the region this afternoon will be well offshore by Wednesday morning.
223 PM EDT TUE JUN 7 2016 Trough axis aloft tonight affects northern zones. Center of high pressure crosses Wednesday night.
147 PM EDT TUE JUN 7 2016 Cooler weather will moderate, and rain chances return as the weekend approaches. Storms that form are likely to contain hail given the aforementioned parameters, and wind gusts to about 25 mph can be expected as the low level lapse rates steepen under the cooling aloft. Sub average near-term temperature can be expected under the broad trough, with readings forecast using consensus-short guidance. The upper trough axis is then forecast to shift quickly eastward as Wednesday progresses, so the previously forecast dry and clearing trend was maintained for the afternoon.
The higher level north to northwest flow and the drier deep layer airmass coming in from the northwest should keep any additional development very isolated. the high surf advisory remains in effect through the remainder of the day. The forecast weather maps show a broad long-wave trof over the eastern US with a narrow mid-level ridge axis building from the Bahamas. Although high temperatures heat up into the lower to mid 90's on Wednesday.
On Wed, diffuse upper trough drifts eastward across the region, which should be help fire at least isolated storms over most of the higher terrain once again by afternoon. With drier air mass and weak downslope gradient, expect max temps to push upward slightly, especially across the plains where some mid 90s will be possible along the lower Arkansas Valley.
320 PM CDT TUE JUN 7 2016 An upper level ridge over the Western CONUS and a longwave trof over the Eastern CONUS with northwesterly flow over the Central United States between the two pressure systems was the synoptic setup this afternoon. the ridge of high pressure is to become established over the Central United States with southerly surface winds returning to Eastern Oklahoma and Northwest Arkansas. latest model solutions continue to indicate the upper ridge shifting east of the CWA and breaking down as a wave moves onto the West Coast and into the Plains.
1212 PM 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.
Continued warm and dry weather conditions today under a high pressure ridge across the western states. Winds will remain breezy today as a weak upper level low moves eastward through Utah.
227 PM EDT TUE JUN 7 2016 Cooler weather is expected today into Wednesday as an upper level trough moves through. Clearing is expected tonight into Wednesday as high pressure builds in.
336 PM PDT TUE JUN 7 2016 Cooling trend through this week as high pressure weakens. High pressure ridging over the West Coast today will weaken and track eastward starting tonight as a trough over the Eastern Pacific Ocean moves into the West Coast. The low will slowly nudge into the Pacific NW for the rest of this week as its associated trough reaches southward into NorCal.
613 PM EDT TUE JUN 7 2016 Showers and a few thunderstorms can be expected until high pressure builds on Wednesday. Any storms that do form are likely to contain hail given the aforementioned parameters, and wind gusts to about 25 mph can be expected as the low level lapse rates steepen under the cooling aloft. Sub average near-term temperature can be expected under the broad trough, with readings forecast using consensus-short guidance. The upper trough axis is then forecast to shift quickly eastward as Wednesday progresses, so the previously forecast dry and clearing trend was maintained for the afternoon.
BROAD DIFFLUENCE ALOFT ASSOCIATED WITH A DEEP TROUGH OF LOW PRESSURE OVER THE EASTERN PACIFIC OCEAN WILL CONTINUE TO SUPPORT SHOWERS AND THUNDERSTORMS THIS AFTERNOON AND EVENING , MAINLY NORTHEAST OF THE CASCADES. INCREASING UPPER LEVEL TROUGHING WILL RESULT IN A SIGNIFICANT COOL DOWN ACROSS THE ENTIRE AREA.
thickest in nw mn as mid level warm advection moves in as 500 mb ridge builds northeast. Warmer Wednesday with highs 75 to 80 in E ND & RRV and 70-75 NW MN.
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 Cape Mendocino by the end of the week.
239 PM CDT TUE JUN 7 2016 High pressure sliding down from the northwest was bringing in a drier airmass to the area today. The high will settle overhead tonight leading to a wonderful "open the windows type of night" with lows in the middle 50s area wide.
133 PM EDT TUE JUN 7 2016 A cold front will move through today. Center of high pressure crosses Wednesday night.
Tonight Through Wednesday night Arkansas continues to sit in northwest flow between an amplified ridge over the rockies and east coast troughing. A weak wind profile throughout the highly mixed boundary layer should keep winds below 10 knots. Northeast Arkansas, which lies closer in proximatey to the large scale thermal trough, and higher elevations in the Ozakrs, will stay closer to average. Conditions will be simliar on Wednesday as the low and mid level ridge of high pressure moves overhead. As the high slides eastward, winds will become more easterly. That said, pwats will still be in the lower 1 inch range and large scale subsidence will still prohibit any type of precipitation in the area for the period.
The current weather scenario has a dominant high pressure system from the prairie provinces of Canada south thorough the Dakotas into Nebraska. To the west, a warm front extends from Alberta through eastern Montana into Wyoming. Very warm air across the high plains of Montana/Wyoming will move into North Dakota as the warm front moves east Wednesday creating an elevated mixed layer above 5000 feet that shows up well in the NAM BUFKIT soundings from Bismarck to Minot and east. The weather pattern aloft will feature an upper low over the Pacific Northwest and a resultant downstream ridge over the central and northern plains.
150 PM EDT TUE JUN 7 2016 A cold front will move south of the area this morning.
302 PM MDT TUE JUN 7 2016 Today's break in cloud cover and precipitation won't last long as an upper level trough passes through eastern Utah and western Colorado tonight into early Wednesday morning. Available moisture increases with this passing trough and the dynamics associated with the trough will bring nocturnal and early morning showers to the region. Temperatures will be running a few degrees cooler Wednesday due to cloud cover and slightly cooler air aloft.
HIGH PRESSURE AT THE SURFACE IS OVER THE AREA AND WILL BE MOVING EASTWARD. High pressure over the mid and lower Missouri Valley this morning will begin to shift east tonight and continue to move east toward the Tennessee Valley on Wednesday.
258 PM CDT TUE JUN 7 2016 The upper level ridge axis over New Mexico will flatten slightly but still bulge out across the Texas south plains region tonight and Wednesday.
/issued 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.
1206 PM 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.
241 PM MDT TUE JUN 7 2016 Thunderstorms have formed over the higher terrain early this afternoon. For Wednesday, a weak upper level trough will move from the Great Basin into northwest Colorado.
Issued by National Weather Service Lake Charles LA 322 PM CDT TUE JUN 7 2016 Temperatures this afternoon climbed into the mid 80s to upper 80s across south Padre Island and Bayview/Port Isabel where cooler marine air helped to offset daytime heating.
106 PM EDT TUE JUN 7 2016 Gusty winds will stick around into the late afternoon hours as a trough swings through north of the area. Once again patchy fog will be possible tonight, with the highest chances at KTRI.
Surface wise, a deepening low pressure system (1000 mb) is located just offshore of the North Carolina coast with an associated from aligned across North Florida and into the South Central Gulf of Mexico.
449 PM CDT TUE JUN 7 2016 For tonight, the next round of showers and tstms currently forming over the higher terrain of sern CO and ern NM will slide sewd into at leasxt the nwrn half of fcst area through the evening hours based on current speed and trajectory, assuming much of the precipitation holds together.
Have updated to extend the high risk of rip currents until 12Z Wednesday based on current beach cams and current onshore swell of 9-10 seconds which gradually diminishes to 7-8 seconds overnight. Expect surf conditions to subside sufficiently to stay with the current expiration of the high surf advisory at 00Z Wednesday. The higher level north to northwest flow and the drier deep layer airmass coming in from the northwest should keep any additional development very isolated. the high surf advisory remains in effect through the remainder of the day. The forecast weather maps show a broad long-wave trof over the eastern US with a narrow mid-level ridge axis building from the Bahamas. Although high temperatures heat up into the lower to mid 90's on Wednesday.
The biggest condition of note is the gusty winds across the area due to the tightening pressure gradient as the trough axis swings across to our north. Temperatures tomorrow will be a few degrees lower than today as cooler air continues to funnel in from the west/northwest.
232 PM EDT TUE JUN 7 2016 A cold front will move across the region today producing showers and thunderstorms, with a few possibly being severe. An upper level low will move overhead on Wednesday and allow for another chance of showers and thunderstorms.
Decided to stay on the higher side of guidance for overnight lows, since the high clouds should decrease the impact of radiational cooling. Lows should range from the mid-upper 60s across much of SE AL and SW GA, and should remain in the lower 70s across most of northern FL.
309 PM CDT TUE JUN 7 2016 High pressure building into the area today led to dry air and cooler temperatures under clear skies. This high pressure will slide across the area tonight and to the east on Wednesday and will be the main driver of weather tomorrow. With high pressure driving the forecast the best chance for a forecast bust would be in the temperature realm. Calmer winds tonight, coupled with cooler H85 temps, temperatures will likely reach the low 50s and possibly the mid 40s, especially in the favored river valleys. Tomorrow, the center of the high migrates to the east and west to southwest sfc flow returns. Slightly warmer temperatures return to the area along with boundary layer moisture.
1146 PM CDT Mon Oct 17 2016 A cold front continues to work its way southward into the Texas Panhandle and Northern Oklahoma this evening, and should make it near Bowie/0F2 Tuesday morning before becoming stationary. The location of the front may create a slightly veering wind field at the low levels of the atmosphere, which may in turn limit the northward extent of stratus. Clouds should break up during the mid-morning hours as a cold front slides southward towards the area.
The organized area of snow over the northern mountains has dissipated, but there are still some shallow clouds and flurries over the ridges. showers will linger longest along the higher west facing slopes. strongest winds have occurred over Weld County with northerly downslope off the Cheyenne Ridge. Cooler temperatures and less wind on Tuesday. The flow aloft will be more southwesterly ahead of an upper level trough which will move into northwestern CO late in the day. Strong westerly flow aloft will remain over the state tomorrow night as a short wave trough passes.

901 PM EDT Mon Oct 17 2016 A large area of high pressure near the DELMARVA coast is the catalyst for the fresh to strong winds across the Florida Keys and surrounding coastal waters this evening. The ridge mention above has strengthened this evening and is reflected in the winds across the Keys.
Update An upper wave is moving through the broad trough over Montana bringing some shower activity to the region. Proton Previous Discussion Broad upper trough will keep things across the area a bit unsettled during this period.
Timing of cold frontal passage with surface wind shift to north has been sped up slightly. Gusty, downslope winds and the thermal ridge were able to warm us into the mid 90s and a few 100 degree readings despite periods of cirrus this morning and afternoon. Heights are falling as the upper level ridge sinks further into Texas and shifts slightly eastward as a more zonal flow pattern sets up across the central portion of the country. A cold front over northern Kansas will continue moving southward as high pressure builds southward across CO.
828 PM CDT Mon Oct 17 2016 Quiet wx conditions prevail across the cntrl TN Valley this early Mon evening, as high pressure remains in place over the srn Atlantic basin. Temp trends range from the lower/mid 70s w to the mid/upper 60s e, and these readings should continue to fall a few more degrees heading into the overnight hrs given dew pts mainly around 55-60F. The above mentioned upper high moving to the ENE will continue the dry and warm trend. Tuesday as the upper high and warm temperatures aloft are realized, highs should warm into the mid/upper 80s.
Snow levels will lower to around 5,500ft as cooler air aloft passes overhead.
Unseasonably warm temperatures will continue over the next few days as the upper level ridge moves overhead. Current forecast has 88 for the high on Tuesday, so possibly some extra mixing from the stronger winds could push the temperature higher, but 88 would be enough to break the record of 87 set back in 1953.
A cold front will move into the region overnight. Overnight lows are expected to be around 25 degrees above average except for the extreme northwestern corner of the CWA where the cold front will have made sufficient progress to affect overnight lows. Therefore, have continued some more widespread PoPs across the region, with the highest PoPs for those areas and times that mdls are in agreement. The GFS is slower with the upper trof late this week which poses some uncertainty for temps this weekend. The gusts will diminish tomorrow with the approach of a cold front and winds will veer out of the northwest behind it. The gusts will diminish tomorrow as a cold front approaches the terminal from the northwest and moves through early tomorrow evening.
542 PM MDT Mon Oct 17 2016 The cold front has accelerated across the Roan and eastern Tavaputs Plateaus this afternoon. Very weak reflection of wave moving in with elevated moisture over the cold front may keep some isolated showers going over the central divide mountains but confidence low this occurs. This wave will also bring along a front and another shot of cooler air.
1051 PM CDT Mon Oct 17 2016 A lingering band of light fog/stratus across far southeast South Dakota/northwest Iowa/southwest Minnesota has created quite the temperature variance across the forecast area this afternoon, with temperatures beneath the stratus holding in the mid 60s, which readings on either side have climbed into the lower-mid 70s. Should be a cooler day with highs in the lower to mid 60s, more sunshine and modest westerly flow.
17/23z surface analysis shows the surface front/trough residing just north of the Panhandles in southwestern Kansas and southeastern Colorado. Made adjustments to the hourly trends, holding on to those warmer temperatures through sunset, as the vast majority of guidance continues to undercut temperatures. /issued 248 PM CDT MON OCT 17 2016/ After three days of well above average temperatures and humidity, a cold front will bring some relief. A cold front is expected to enter far northwest Oklahoma by late evening and will move across central Oklahoma (OKC) by sunrise Tuesday.
Local instability associated with isolated -SHRA and mid level clouds will limit the lower clouds and fog potential.
625 PM CDT Mon Oct 17 2016 Despite a cold front marching through the area tonight, a rather large wedge of dry air is fixed in place, negating any sort of precip chances.
Latest SFC analysis was indicating low pressure northeast of the Omaha area, with frontal system extending up into the western U. Associated sfc boundaries and warm front will continue to be the llvl focus for shower and thunderstorm development this evening and overnight acrs these areas just to the north of the local area of concern. Post-frontal lows may dip into the low to mid 50s in the far northwest, while the far east and southeast(last to experience the FROPA) holds up in the mid 60s thru 12z. This feature will be the late day and evening convective focus acrs those areas, while a bubble of high pressure slides toward the area out of the central/northern plains.
High pressure will build over California by midweek and bring dry weather and warmer afternoon temperatures through the weekend. Conditions for the remainder of the week will be dry and warming as model consensus shows rather strong ridging building in over the region.
1101 PM EDT Mon Oct 17 2016 Dry high pressure will build across the area through the middle of the week.
Quiet wx conditions prevail across the cntrl TN Valley this early Mon evening, as high pressure remains in place over the srn Atlantic basin. Temp trends range from the lower/mid 70s w to the mid/upper 60s e, and these readings should continue to fall a few more degrees heading into the overnight hrs given dew pts mainly around 55-60F. The above mentioned upper high moving to the ENE will continue the dry and warm trend. Tuesday as the upper high and warm temperatures aloft are realized, highs should warm into the mid/upper 80s.
1154 PM CDT Mon Oct 17 2016 Despite a cold front marching through the area tonight, a rather large wedge of dry air is fixed in place, negating any sort of precip chances.
A weak cold front otherwise will likely bring west to northwest winds 10 KTS or less to KABI Tuesday. An upper level ridge will continue to dominate the weather across much of Texas on Tuesday. Only slightly cooler temperatures are expected behind the front along with a with north winds of 5 to 10 mph. Highs will range from the mid to upper 80s behind the front, to the low to mid 90s elsewhere.
(ISSUED 801 PM CDT MON OCT 17 2016 ) Upper level high pressure will continue to dominate through the period.
801 PM CDT MON OCT 17 2016 Upper level high pressure will continue to dominate through the period.
Clouds should break up during the mid-morning hours as a cold front slides southward towards the area. 24-Bain /ISSUED 639 PM CDT Mon Oct 17 2016/ An upper level disturbance responsible for the convection in the Upper Midwest will nudge a cold front southward through the Plains into OK and NW TX.
814 PM EDT Mon Oct 17 2016 High pressure will maintain warm weather until passage of a mid week cold front. By late day, an approaching cold front will bring showers chances for Northwest PA.
1127 PM CDT MON OCT 17 2016 Cold front passage still on track very similar to times adjusted to previously. Latest trends support a slightly earlier cold front passage, and we have adjusted to faster passage by a couple hours. Also at 2 pm, shallow moisture was hanging on across the southeast Rolling Plains - however the atmosphere will remain firmly capped in the subsident regime to the south of a strong upper-level jet moving across the southern Rockies and out into the high plains.
