455 AM CDT WED JUN 8 2016 Weak cold front attempting to back door into the region this morning will slowly slip farther south to along the Gulf coast with a slight reinforcement of drier air filtering in later on today. Don't expect any relief in the temperature department as highs will climb into the lower to mid 90s under mostly clear skies with just some spotty cumulus developing during the heat of the afternoon.
337 AM EDT WED JUN 8 2016 Clear skies prevailed over the forecast area this morning as a dry cold front continued to move southeast through GA. A northwest flow aloft will continue today as an upper level high pressure ridge sets up over the central U. dry high pressure dominating across the deep south through at least the weekend and possibly beyond.
251 AM CDT WED JUN 8 2016 A broad upper level trough across the eastern Great Lakes this morning will move east into New England Tonight. An amplified upper level ridge across the western US will begin to slowly move east towards the northern and central high plains late this afternoon and Tonight.
An upper level ridge will begin to build east from the Plains by Thursday as low level flow turns southerly on the back side of the departing high.
(Issued 943 PM CDT TUE JUN 7 2016) Before a cold front moved southward across the region during the later afternoon hours, under mostly sunny skies, very warm to hot temperatures and breezy conditions were realized across the region. The above noted cold front has moved further south, now between Birmingham and Montgomery.
Expect a slight warm up in high temperatures today with highs in the lower 90s across southeast Alabama, southwestern Georgia and the coast with the mid 90s across the Big Bend and Florida panhandle.
215 AM EDT WED JUN 8 2016 Cool high pressure builds in today.
High pressure will remain in place of over the next few days. Drier air has moved into the area and with that warmer daytime highs should be expected. Expect highs to reach the low to possibly mid 90s over the next few days. With high pressure in place rain chances will be near zero for today and tomorrow.
416 AM EDT WED JUN 8 2016 Following a few morning showers, a dry and much cooler air mass will overspread the area.
640 AM EDT WED JUN 8 2016 High pressure moving into the area will provide mostly sunny skies today.
523 AM CDT WED JUN 8 2016 A cold front is currently pushing through the southern counties this morning. Guidance yesterday came in too cool as temperatures actually warmed into the lower and mid 90s. 88 With the current upper level trough shifting into the eastern conus and soon into the Atlantic, an amplified upper ridge will set into place over the central US. With the upper ridge in place, a high pressure cell will drop down from the Ohio River Valley and push northerly winds into the CWA. As seen today, cooler temps will remain in the area ranging from mid 60s during the evening hours and mid 80s to low 90s for the daily max.
316 AM EDT WED JUN 8 2016 High pressure will be firmly in control over the next 36 hours, setting up a pleasant stretch of weather through Thursday. As the high shifts east Thursday, slightly milder temperatures will return, but still comfortable for June. Dewpoints might not recover as quickly as models anticipate on Thursday as the low level flow really doesn't support the moisture recovery, so have stayed under guidance with daytime mixing. Lows tonight should be well into the 40s for most valley locations with the high just about on top of us. Record lows are in the low 40s at London and upper 40s at Jackson and despite the chilly temperatures, these records may be hard to beat.
Gulf moisture will increase beginning Thursday with a developing lee trough across the Central High Plains. Therefore, it will start to feel a bit warmer during the afternoon with heat index values reaching the middle and upper 90s. Warm and humid conditions will continue on the weekend with high pressure aloft and abundant low level moisture.
A reinforcing dry front will move through our region overnight, behind which drier and slightly cooler air will filter in through Thursday.
Upper-level ridging will dominate for Thu-Fri, with deep subsidence limiting any chances for convection to the high country and promoting the warmest temperatures of the season for much of the area.
The short term period begins with an upper ridge stretching from Texas through the northern plains and into Canada, and upper troughs in the pacific northwest and the northeast. The subtropical ridge axis is forecast to be across the Florida straits. At the surface, weak high pressure will build north of the region, and a stalled frontal boundary is forecast to be across central Florida. Warm and dry air aloft will limit convection across the region, with freezing levels approaching 16 kft. Otherwise, near normal temperatures and dry conditions will prevail with highs in the low to mid 90s inland and mid/upper 80s along the coast and lows in the upper 60s to mid 70s.
239 AM EDT WED JUN 8 2016 An upper level low will move overhead on today and allow for another chance of showers and thunderstorms.
243 AM CDT WED JUN 8 2016 Clear skies, noticeably cooler temperatures and much more comfortable air is rampant across Middle Tennessee this morning. Thursday starts the transition to warmer temperatures. The upper level ridge that has been plaguing the Western U.
339 AM CDT WED JUN 8 2016 Upper ridge remains centered west of Baja this morning with the ridge axis running up across the Intermountain West to Canada.
An upper level trough will cross the area this afternoon. Weak high pressure then builds through the end of the work week.
This will undoubtedly play a role in degree of destabilization and to some extent probably the location of the warm front.
122 AM EDT WED JUN 8 2016 Dry and cool high pressure will build into the area Wednesday an remain in place through Thursday. Heat and humidity return for the weekend as the high moves offshore. At the surface, drier and cooler high pressure will steadily build in from the west.
432 AM EDT WED JUN 8 2016 Cold front continues to move away from the region with high pressure building in from the northwest. As the high overtakes the area drier and slightly cooler air will move in for today and Thursday.
1223 AM CDT WED JUN 8 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. For Thursday into the weekend, broad upper level ridging will dominate and we will be much above average temperatures with highs in the 90s and lows in the mid 60s to near 70.
The first in a series of cooler weather systems will move through southwest Washington and northwest Oregon today with lots of clouds, cooler temperatures, and a few showers. A second cooler low will drop south out of the Gulf of Alaska later tonight and Thursday to reinforce the pattern and produce a better chance of showers.
303 AM PDT WED JUN 8 2016 Above average temperatures today will cool down to average or slightly below average by the weekend as low pressure slowly moves into the Pacific Northwest.
601 AM EDT WED JUN 8 2016 Following a few morning showers, a dry and much cooler air mass will overspread the area.
135 AM EDT WED JUN 8 2016 Aviation High pressure builds in tonight with fair weather on Wednesday.
Pattern overview: A somewhat amplified flow pattern is in play across North America with ridging across the western CONUS and downstream troughing through the Great Lakes/Ohio Valley and through New England region. Daytime CU potential looks limited with surface dewpoints falling off into the lower and middle 30s. Another day with gustier NW winds will make it feel even cooler although more sun today will help. etc) will probably dip into the lower to middle 30s and potentially see some frost overnight.
109 AM EDT WED JUN 8 2016 Following a few morning showers, a dry and much cooler air mass will overspread the area.
The ridge of high pressure is finally shifting off to the east causing the upper level flow to become more southwesterly. A cold front is still on track to move through the Northern Rockies tonight.
Another round of convection will fire early this afternoon, with a line over the lower valley moving slowly west. Some shower activity will develop again on Thursday, but the upper low will have shifted a bit farther offshore, so convection may be slightly weaker.
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.
On Thu a weak upr trof wl be ovr ern CO and isold to sct pcpn is expected ovr the hyr trrn but may also be found ovr portions of the sern plains. An upr ridge wl be ovr the area on Fri but there wl still be enough mstr for at least isold pcpn ovr the hyr trrn. High temps both Thu and Fri wl be 10 degrees or more above average ovr the sern plains, and 5-10 degree above average in the high valleys.
239 AM PDT WED JUN 8 2016 Cooling trend through this week as high pressure weakens. Upper level high pressure over the western U. will bring generally fair skies to the region today while a Pacific trough moving in off the Pacific brings onshore flow and a cooling trend.
Some shower activity will develop again on Thursday, but the upper low will have shifted a bit farther offshore, so convection may be slightly weaker.
300 AM EDT WED JUN 8 2016 High pressure will build in today and persist through the end of the week. Temps currently falling through the 60s and low 70s on their way to lows in the low 60s inland to upper 60s beaches. A very pleasant June evening with lows dropping down to the low/mid 50s interior to 55-60 on the coast. Dry Wed thru Fri with warming temps as the slightly cooler airmass modifies.
Guidance shows little impact for the lower valley TAF sites. A 500 mb trough will remain positioned to the east of the RGV which will maintain the area on the more subsident side of the trough limiting the conv potential for most of the upcoming TAF forecast period. /issued Issued by National Weather Service Lake Charles LA/ 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. high pressure to the west and east of south Texas will leave the region in a zone of slightly lower pressure through Thursday.
337 AM CDT WED JUN 8 2016 A clear night is underway throughout the Mid-South after a cold front, currently stretching from Kansas to New England, pushed through the region earlier today bringing drier, cooler air to the Mid- South.
654 AM EDT WED JUN 8 2016 A higher degree of stability will exist today as drier air accompanies approaching high pressure.
700 AM EDT WED JUN 8 2016 High pressure will build in today and persist through the end of the week. A very pleasant June evening with lows dropping down to the low/mid 50s interior to 55-60 on the coast. Dry Wed thru Fri with warming temps as the slightly cooler airmass modifies.
321 AM EDT WED JUN 8 2016 High pressure moving into the area will provide mostly sunny skies today.
High pressure over the Ohio Valley will build into central NC today and Thursday.
640 AM EDT WED JUN 8 2016 An upper level trough will cross the area this afternoon. Weak high pressure then builds through the end of the work week.
Water vapor imagery shows shows a weak closed upper level low just to our south with the center of the circulation located just to the west-northwest of Corpus Christi. Global and hi-res models runs indicate this low will continue to slowly weaken and remain quasi-stationary, but an unstable atmosphere and modest moisture surge with PW values increasing into the 1. Models are in general agreement that the quasi- stationary upper level low will move slowly to the east-southeast on Thursday. Weak negative vorticity advection on the west side of the open trough should help cause a lower coverage of shower and thunderstorm activity on Thursday afternoon confined to areas along and east of the I-35 corridor where enough daytime heating may promote a weak sea breeze circulation to develop.
153 AM EDT WED JUN 8 2016 Following a few morning showers, a dry and much cooler air mass will overspread the area.
612 AM EDT WED JUN 8 2016 Cold front continues to move away from the region with high pressure building in from the northwest. As the high overtakes the area drier and slightly cooler air will move in for today and Thursday.
634 AM EDT WED JUN 8 2016 A cold front will cross the state early this morning.
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. The upper ridge will remain over the Western U. Look for mild nights, and max temps Thu aftn in the 80s for the high valleys, and upper 80s to mid 90s for the e plains.
346 AM MDT WED JUN 8 2016 Upper ridging continues to dominate the wrn CONUS. Upper ridge axis and thermal ridge will move across the nrn plains Thursday. This will bring warmer temps reaching the upper 80s to upper 90s. Models are now showing a weak cold front pushing into the area late Thur afternoon/evening which could produce some storms mainly during the evening.
924 AM EDT Wed Oct 12 2016 High pressure will maintain dry weather today before showers return with a cold front early Thursday. High pressure will continue to slide eastward as a cold front approaches. Southerly flow in advance of the boundary and mostly sunny skies should support high temperatures that are about 10 degrees warmer than average today. Clouds and shower chances should increase tonight through early Thursday with the approach and passage of a cold front.
See no reason why this would not continue next several hours as cold front moves through southern WI. Cold front currently pushing across western CWA.
Given the strength of extended jet, the low level leeside trough will be pushed out a bit farther east than usual, and this will actually act to reduce our surface winds with the strongest MSLP gradient off to our east.
948 AM EDT Wed Oct 12 2016 High pressure will remain centered off the northeastern United States coast today. A cold front will pass through the area late Thursday.
1050 AM EDT Wed Oct 12 2016 Rain-free, mild weather will continue through tonight, as high pressure slowly retreats off the coast. Showers are expected to cross the region Thursday, associated with an incoming cold front.
Gilchrist Previous discussion:Upper trough will move to the east this morning. Sunshine will allow for somewhat warmer temperatures today although snow cover will hold temperatures down in some areas. Upper ridge will be over Montana tonight and Thursday. Temperatures will be warmer on Thursday as most of the lingering snow cover should be melted. As the ridge moves to the east Thursday Night, flow aloft will turn to the southwest as an upper trough moves inland from the Pacific Coast.
A longwave trof over the central and northern Plains advances into the interior eastern states through tonight, while a broad ridge persists over the Gulf.
A cold front across the Panhandle will drop south today, reaching KABI by early afternoon and then slowly working its way farther south across the rest of the terminals tonight. /issued 352 AM CDT WED OCT 12 2016/ (Today and Tonight) Cold front is reaching the northern areas of the Texas Panhandle early this morning, on pace to reach the I-20 corridor from Sweetwater to Abilene by early to mid afternoon.
Fair weather continues today as a weak upper level ridge shifts east into the Great Basin. These forecast high temperatures are a couple degrees cooler than normal for this time of year.
526 AM MDT Wed Oct 12 2016 Latest upper air analysis has a long wave trough moving onto the Northern Plains. Further west a short wave trough was moving onshore. At the surface a cold front had moved south through Kansas and Colorado. Early this morning there may be some lingering rain over the Southwest Nebraska counties where weak lift persists before the 500mb trough axis moves through. North winds will be strongest this morning then become light this afternoon as high pressure builds in. Highs today will be Tonight lows will fall into the lower to mid 30s. A weak upper level short wave trough does move in from the west during the overnight hours, but the lift is very weak. Thursday morning kept the forecast dry as the weak short wave trough moves through for the same reasons as stated previously.
1056 AM EDT Wed Oct 12 2016 High pressure along the east coast will keep conditions mild and dry across the region through Thursday.

1031 AM EDT Wed Oct 12 2016 High pressure will move east of the region today. A cold front will approach later Thursday then cross the area Thursday night.
This will result in much cooler temperatures and not likely to get out of the 40s across the plains. weakening qg ascent as upper trough expected to the trof axis shifting to the east. High pressure at the surface and aloft will be over the region. Overall much cooler with a dry and stable airmass in place this afternoon and tonight. and a lee side trough starts to form over eastern CO.
Expected these to move north from the Coastal Plains to along the Highway 77 corridor by midday with a thunderstorm or three possible this afternoon at max heating. A weak cold front drops south into Central Texas late tonight into Thursday as a weak mid level trough and a favorable quadrant of a small upper level jet approaches from the west. Upward forcing by the front, trough, and jet on this moisture will generate showers and thunderstorms Thursday. With the Subtropical Ridge nearby and PWs still near or below normal, only isolated coverage is expected.
In addition the cold front now entering NW OK will progress through the area with a wind shift. intermittently affecting many of the terminals and we have included MVFR ceilings to account for the lower clouds. The strong cold front currently into south central KS will be near the I-44 corridor around noon and through the western AR and SE OK by mid evening.
1047 AM MDT Wed Oct 12 2016 Upper level analysis has trof axis swinging through the Northern Plains at the moment, with ridging moving onto the west coast. At the surface, cold Canadian high pressure is located across Montana and the western Dakotas. Upper trof pushes east of the area today as western ridge moves into the great basin area. Lows will drop near or below freezing tonight under clear skies. Upper ridge will build across the Central Rockies as light southerly boundary layer flow continues, bringing warmer air back into the region.
952 AM EDT Wed Oct 12 2016 High pressure will allow for dry conditions across the region through most of the daytime hours today. A cold front will move through tonight bringing showers and cooler weather to the region.
1247 PM EDT Wed Oct 12 2016 Cool and dry high pressure will extend over the area from the north through tonight.
Temperatures have already reached their lowest point for the morning, and risen to near or above freezing in most area valleys. Models are having a hard time characterizing the low level moisture, but they do indicate clearing between 12/1800z to 12/1900z.
733 AM EDT Wed Oct 12 2016 High pressure to our east will allow for a light southerly wind today. A cold front will pass through on Thursday morning and early afternoon bringing showers to mainly the northern and central mountains.
950 AM EDT Wed Oct 12 2016 Cool and dry high pressure will extend over the area from the north through tonight.
Cold front looks to be in the nrn Panhandle, while winds at the TAF sites are less than 10kts with clear skies. /issued 351 AM CDT WED OCT 12 2016/ Mostly clear skies are across the area with an upper trough over the Northern Plains and mostly zonal flow over West Texas and southeast New Mexico. This upper trough will move eastward today and push a cold front south into the CWA this afternoon and evening. Expect high temperatures today to reach the low 90s across central and southern areas of the Permian Basin; however, temperatures today will be very dependent on the timing of the front.
653 AM CDT WED OCT 12 2016 A cold front remains just to the northwest of the central IL forecast area early this morning. The main upper level trough will progress into the area mid morning through evening as the cold front progresses from Galesburg through lawrenceville bringing an active period of showers and thunderstorms. highs ranging from 64 in Galesburg to 77 in Lawrenceville can be expected as cooler air starts moving in by mid morning in Galesburg.
1048 AM CDT WED OCT 12 2016 15z/10am analysis shows a narrow band of convection developing immediately ahead of a cold front along the Illinois River. Once the front passes, much cooler conditions will filter into the region for tonight, with the potential for frost west of the Illinois River. A cold front remains just to the northwest of the central IL forecast area early this morning. The main upper level trough will progress into the area mid morning through evening as the cold front progresses from Galesburg through lawrenceville bringing an active period of showers and thunderstorms. highs ranging from 64 in Galesburg to 77 in Lawrenceville can be expected as cooler air starts moving in by mid morning in Galesburg.
704 AM CDT WED OCT 12 2016 Early morning water vapor imagery together with GFS 500mb heights revealed a large upper level trough over the high plains with large scale ascent over the Upper Midwest. Tonight high pressure will build across the region and skies will clear which should allow temperatures to fall into the upper 20s at most locations, with lower 30s elsewhere.
725 AM EDT Wed Oct 12 2016 Cool and dry high pressure will extend over the area from the north through tonight.
654 AM CDT WED OCT 12 2016 Cold front has moved through the Northland leading to a cooler Canadian airmass moving in today. With fairly good mixing winds may be breezy into the morning with gusts to 20mph or so, but weaken in the afternoon as high pressure builds in from the west and the winds aloft become weaker. This evening much of the stratocumulus clouds that develop in the wake of the front and associated upper level trough will dissipate leading to clears skies and a cold night - the coldest so far this season with lows in the upper 20s away from Lake Superior, warmer by the lake. On Thursday High Pressure across the eastern plains into the mid- Mississippi river valley will result in sunny skies.
1251 PM EDT Wed Oct 12 2016 High pressure will move east of the region today. A cold front will approach later Thursday then cross the area Thursday night.
Under partly cloudy skies, temperatures are in the lower to middle 80s. A small craft advisory remains for the Gulf waters offshore from the Lower Keys and well west of Mainland Monroe County, and across the Straits of Florida.
