High pressure will help to keep things dry tonight and into tomorrow. /ISSUED 404 AM CDT Fri Oct 21 2016/ Nice wx will be on tap for the next several days in the wake of the cold front that pushed thru the region yesterday. 47 Strong and gusty north winds in the wake of the cold front are ex- expected to continue over all the coastal waters this morning and into this afternoon for the offshore waters. No major change with the rest of the forecast as winds continue to decrease by to- night as high pressure builds into the region. Onshore winds will gradually return by Saturday night as the high shifts east of the area. 41 Mid/high clouds continuing to clear to the south this morning as the cold front moves further into the Gulf.
High pressure will shift east today with a southwesterly flow developing for the weekend.
641 AM CDT Fri Oct 21 2016 Not much going today other than the high clouds and the warming temperatures. Highs will be warmer today than yesterday despite the high level clouds. Raised the highs a little in southwest Minnesota due to favorable downsloping winds off the Buffalo Ridge which will add a few degrees to the temps. Then the surface winds will begin to veer to the northwest Saturday night behind a very weak cold front, ushered through by a mid level short wave maximized near 700mb passing across the Dakotas and Minnesota.
Some showers associated with broad low/mid level warm advection ahead of the wave are expected with the highest chances across the north, although will need to monitor the southern extent of any showers. The warmest temps today will be across the west with some 60s possible, with cooler highs closer to 50 farther east. Clearing is expected later this afternoon and tonight as weak high pressure builds into the area.
829 AM EDT Fri Oct 21 2016 Rain will taper to showers this afternoon as low pressure and a cold front slowly moves east of the area. Much cooler weather is expected through the weekend. A deepening upper trough is progged to approach the region today, keeping showers in the area through the afternoon. The trough axis will pass to the east of the area late this evening, and the colder air will continue to advect in. Cold advection in northwest flow, will keep in shower chances Saturday, but this too will drift eastward as the large upper level low swings northeastward toward New England. Locations in the ridge counties, especially on the peaks, could see a few snow showers mix in Saturday morning. Building high pressure will bring and end to any lingering showers over the northeast Saturday evening.
Today and Tonight, an upper trough was located across the Mid MS river valley early this morning and will move east, off the mid Atlantic coast late Tonight. An upper level ridge across the southwestern US will slowly drift east into the southern high plains by late Tonight. After a cool start this morning with temperatures in the mid to upper 30s, highs Today will reach the lower to mid 60s with some upper 60 degree highs across the southwest counties. Overnight lows will only drop into the lower to mid 40s Tonight.
Cold front well to our east with light scattered showers currently ongoing across the Central Valley and northward. Chattanooga Airport, TN 64 43 65 42 / 10 0 0 0 Knoxville McGhee Tyson Airport, TN 61 42 62 40 / 20 10 0 0 Oak Ridge, TN 61 42 62 40 / 20 0 0 0 Tri Cities Airport, TN 58 40 55 35 / 50 10 10 0.
Cold front has entirely passed through Middle Tennessee with still a few light radar echoes showing up over the Cumberland Plateau. A brisk northerly flow is advecting cooler, drier air into Middle Tennessee with the clearing line now reaching into far western TN/KY. Can't completely rule out a few places getting some frost, but won't include this in the grids just yet as dew points will remain several degrees above freezing. High pressure will build to our south over the weekend, with return flow by Saturday or Saturday night.
A large upper ridge will move east across the area, with its axis passing overhead this evening. Warmer temperatures, clear skies and dry weather will result across the forecast area. Dry air between 750 and 550 mb, as evidenced by the soundings from KGJT and KDEN has produced humidities in the teens across the higher mountains. Even though skies are expected to be clear tonight, the upper ridge and surface lee trough will produce minimum temperatures 10 to 15 degrees warmer than climatologically normal, especially east of the divide and over the plains.
Southerly winds will pickup a bit more on Saturday with highs near normal in the low 60s far east to around 70 over central Missouri. A dry fropa is expected on Sun with cooler temps on Mon. With good agreement in timing and thermal profile ahead of the fnt, raised temps for Sun twd the warmer guidance.
Still some pockets of freezing temperatures around this morning, including at least 28 degrees so far here at the Pueblo Airport. However, warmer air is already returning aloft as upper high pressure begins to rebuild over the region. So, a big warmup is occurring in the airmass just above the lower lying valleys areas, such as Pueblo. As the day progresses, the cold air currently trapped in the valleys will eventually be mixed away and replaced with the warmer air that is moving in. Upper high pressure will keep skies mostly clear and precipitation out of the forecast through tonight. Unseasonably warm and dry conditions will continue through the weekend beneath persistent upper ridge. Rockies, well north of the area, will send a shallow dry cold front through the southeast plains Saturday night.
946 AM EDT Fri Oct 21 2016 Low pressure is well east of the region this morning as we await the passage of the upper level trough. As this trough passes it will allow much cooler air to spill into the area.
Due to the additional cloud cover, have lowered highs into the lower 50s near the Indiana border from Danville to Marshall. An upper-level trof axis will pull further east of the area, with the flow trending neutral by later today. At the same time, high pressure will begin to build into the area at the surface. While quiet conditions are anticipated, it will be several degrees cooler than normal, with daytime highs in the 50s and nighttime lows in the 30s. In the interim, very quiet conditions as we will be under the influence of high pressure much of the time.
The weak cold front moves into the northwest late morning/early afternoon and tracks southeast through the forecast area during the afternoon hours. Expect increasing west to northwest winds associated with the cold front but moreso due to the boundary layer mixing out to higher winds aloft during max heating this afternoon. The cold front moves into western ND Saturday afternoon. This would result in warmer daytime highs and stronger winds Saturday night across western and central ND.
A cold front was moving across Georgia this morning, and will move into southeast Georgia over the next couple hours and then through the entire region mid to late afternoon. Warm temperatures are expected this afternoon, with highs in the low to mid 80s. Much drier and cooler air will filter into the region tonight behind the front, and temperatures will plummet into the mid 40s to mid 50s. A cold front will push through the TAF sites this afternoon, with winds increasing out of the northwest to 10-15 knots with higher gusts.
fans of Fall will finally get a few days of near to slightly cooler than normal temperatures, along with clear skies and northerly breezes. Early this morning, temperatures are mostly in the low to middle 50s. Afternoon highs will be in the low to middle 60s across the region. although winds may make it feel slightly cooler. Memphis and most of the Delta Area is expected to cool into the low to middle 40s with temperatures as low as the middle 30s in West Tennessee near the Tennessee River.
630 AM CDT Fri Oct 21 2016 Ridge to the west continues to build east into the northern plains today with warmer temperatures aloft. Dry air in place with light winds will promote rapid cooling tonight across the region, with lows falling to near the freezing mark in favored lower spots. A warm day Saturday with a thermal and upper level ridge across the region.
1129 AM CDT Fri Oct 21 2016 late this morning a cold front was entering the northwest with good mixing in its wake. The weak cold front moves into the northwest late morning/early afternoon and tracks southeast through the forecast area during the afternoon hours. Expect increasing west to northwest winds associated with the cold front but moreso due to the boundary layer mixing out to higher winds aloft during max heating this afternoon. The cold front moves into western ND Saturday afternoon. This would result in warmer daytime highs and stronger winds Saturday night across western and central ND.
745 AM EDT Fri Oct 21 2016 Low pressure is well east of the region this morning as we await the passage of the upper level trough. As this trough passes it will allow much cooler air to spill into the area.
High pressure will build in today behind the cold front that pushed through yesterday. As the ridge settles more over the region, winds will decrease late in the day providing for mainly light winds tonight. Expect highs both today and Saturday mainly in the lower 80s with sunny skies.
Overall quiet forecast period in store as cold air advection continues to drive in cooler temperatures and drier air aloft in the wake of the cold frontal passage. 12Z upper analysis shows the deep longwave trough over the Great Lakes and extending into the Lower MS Valley while northwest flow and cold air advection exists over the ArkLaMiss. Due to the drier air aloft, dewpoints will mix out this afternoon into the low to mid 30s.
1105 AM EDT Fri Oct 21 2016 Currently - Light northerly winds across the Keys are being driven by a subtropical cyclone well east of the Florida peninsula. These north winds continue to bring relatively cooler and drier air across the Keys. Temperatures should be able to climb into the low to mid 80s with dew points lingering in the mid 60s. A cold front is expected to sweep southwards across the area early Saturday as a large high pressure system builds into the southeastern United States.
937 AM MDT Fri Oct 21 2016 Low pressure system continues to move off to the east over the Dakotas with high pressure building in over the region. High pressure ridging will build across the northern Rockies today resulting in rising heights and mild temperatures. Afternoon temperatures will be in the lower 60s west and central with middle 60s to near 70 degrees across the southeast. For Saturday, high pressure ridging gets flattened somewhat as a disturbance moves across the northern half of the state. This will sweep a Pacific cold front across the area late morning/early afternoon ushering in gusty northwest winds. Temperatures Saturday will be slightly cooler but still above normal for this time of year.
/Today/ High pressure currently centered over the state with light and variable winds and chilly temperatures. The high will slide off to the east today with westerly flow setting up aloft and waa.
/issued 223 AM CDT Fri Oct 21 2016/ An upper level ridge of high pressure centered over Arizona will move east across the southern states through the weekend promising above normal temperatures and no precipitation.
1038 AM EDT Fri Oct 21 2016 A slow moving cold front will finally move east of the area this evening.
For Wednesday, upper level northwest flow will continue with a cold front near the Oklahoma border. South winds shift to the east and northeast with a cold front. A couple of things that will probably act to enhance precipitation coverage and intensity later in the week will be 1) a fairly decent surface front which will slow down and perhaps become quasi-stationary across southern Kansas and 2) some minor mid level perturbations/enhanced mid level moisture rotating around weak ridging, thanks to abundance of mountain convection across the southern Rockies.
345 PM CDT TUE JUN 28 2016 An isolated shower or perhaps a few stray thunderstorms are possible across the far southern CWA late this afternoon, but the best pcpn chcs will continue to shift southward in tandem with a southward-moving cold front. Overnight lows in the mid 50s to low 60s should be roughly 5-10 degrees colder than last night, which is cooler than average for this time of year.
Basically good flying weather for the next 24 hours as surface front moves down through the area followed by high pressure with light northerly flow reinforcing the somewhat dry air mass that is already in place.
The upper level high over the Four Corners region will shift a bit southeast over the southern Rockies on Wednesday. Highs are expected to be a degree or two warmer than what occurs today. The forecast will remain dry for the most part as upper level ridging dominates the region.
High pressure will build into the region, bringing a light north wind.
Scattered showers and thunderstorms have increased in coverage this afternoon in response to our warm and soupy airmass in place and a weak cold front sagging south toward our region. The aforementioned cold front should move through the region tonight and clear our area by tomorrow.
For Wednesday, upper level northwest flow will continue with a cold front near the Oklahoma border. South winds shift to the east and northeast with a cold front.
A trough of low pressure is expected to slide into Southeast Georgia this afternoon, which will be an additional focus for convection there.
High temperatures will continue to run in the low to mid 90s despite the front while rain chances will be veyr few and far between.
The first area is across the higher terrain and is associated with the weakening upper low that has moved into northern Mexico. The upper ridge will return by midweek as it builds in from the northwest, though mid level heights won't be too high.
High pressure will move across the state tonight while northwest flow continues at 500mb. A lake breeze will keep temps slightly cooler near Lake Michigan.
241 PM EDT TUE JUN 28 2016 Latest surface analysis shows a pre-frontal trough near a Carrollton to Gainesville line. with area radars showing numerous showers and thunderstorms developing along and south of this trough axis. Expect the frontal trough to continue sagging southward into central GA this afternoon-evening. they agree on the trough/front stalling somewhere near a Columbus to Macon line on Wednesday.
333 PM EDT TUE JUN 28 2016 A cold front will progress through Central NC this evening and stall near the coast or over the SE Coastal Plain of NC tonight through Wednesday. The cold front currently moving through PA/WV/KY will move into central NC later tonight and effectively stall across the CWA on Wednesday.
251 PM CDT TUE JUN 28 2016 18Z surface data indicated high pressure over Minnesota with a frontal boundary from southern Kansas into southern Missouri. The light winds, dry air, and mainly clear skies should allow temperatures to drop into the low to mid 50s tonight. No record lows are expected tonight but favorable cold air drainage at Moline may allow the low to get close to the record.
The marine layer will deepen slightly over the next several days as an upper trough moves closer from the west and temperatures aloft cool some. The approaching upper trough will push marine stratus clouds back into the coast and coastal valleys this evening, while offshore northeasterly flow keeps most areas south of Cape Blanco clear.
650 PM EDT TUE JUN 28 2016 A cold front will progress through central NC overnight, then stall near the coast Wednesday.
This increase in convection will continue to be driven by the interaction between deep layer tropical moisture, and a difluent flow pattern and troughing in the upper levels.
The upper ridge over the Four Corners will gradually weaken with swath of monsoonal moisture overspreading the CWA.
Still looks like a cold front will drop from north to south across the FA Wednesday night. Any pcpn looks to move south and east of the FA by 18z Thu with high pressure moving back in. The high should be right over the top of the FA Thu night with clear skies and light winds.
601 PM EDT TUE JUN 28 2016 A cold front will progress through central NC overnight, then stall near the coast Wednesday.
Even drier air is further north behind a cold front extending through southern Missouri and Kentucky, where dewpoints drop into the lower 60s to mid 50s. Cold air advection via northwesterly flow aloft and cooler morning temperatures in the lower to mid 60s will give us a noticeable break from recent heat towards the middle of the week.
Low temperatures tonight will bottom out in the lower to middle 70s across much of the area. Highs tomorrow will once again top out in the lower 90s to upper 90s across the area.
525 PM EDT TUE JUN 28 2016 An upper trough will move east of the region this evening as high pressure builds in from the upper Great Lakes.
210 PM EDT TUE JUN 28 2016 Cooler air will continue to move into the area today accompanied by post frontal clouds. Skies will clear tonight as a ridge of high pressure moves into the area. Water vapor imagery depicting upper trof moving into the eastern great lakes region this afternoon.
332 PM EDT TUE JUN 28 2016 A cold front will move slowly across central Pennsylvania and the triggering the likelihood of showers and perhaps a few thunderstorms containing gusty winds and hail.
The remainder of the week looks hot and dry as upper ridging builds into the area from the west/southwest. An upper trough is forecast to move into the eastern US, dragging a weak cold front into the Central Plains.
Afternoon highs are still expected to peak in the low to mid 80s though areas near the Missouri River and points north should stay in the low 80s. Near normal to just below normal temperatures are expected through the next several days as the ridge currently over the Rockies begins to weaken. Aside from the cooler temperatures, an active pattern will commence under northwest flow aloft Wednesday morning.
upper ridge will continue to shift north and eastward across western portions of the district today. Afternoon heating combined with weak impulses embedded within the ridge will fire off another round of showers and thunderstorms across the mountains during the afternoon. This area is where dew points stay the highest. High temperatures today should be slightly cooler than yesterday for all areas, but particularly out east.
The 18z upper level analysis depicts ridging across the western states with troughing across the Great Lakes. A surface cold front stretches from the central Plains eastward to the northeast states. Overnight lows will generally be in the low to mid 70s.
We will also remain in cyclonic flow aloft and this should help to reinforce the drier and cooler air.
147 PM EDT TUE JUN 28 2016 Aviation A northerly flow of cooler air will prevail today here in Michigan as low pressure pulls off to the east. Tonight the clouds will thin out leading to a much cooler than normal night.
High pressure over the region will result in continued very warm and dry inland conditions through midweek. This large temperature gradient is the result of a broad 595DM ridge over the Four Corners region warming from the east and cool marine air cooling from the west, with a thermal trough in between. As of 2PM, temperatures are 2 to 6 degrees cooler than this time yesterday with slightly more cooling seen further inland than near the coast. The Four Corners ridge is modeled to gradually become flat and weakened over the central CONUS through the remainder of the week.
148 PM EDT TUE JUN 28 2016 High pressure will build over the mid section of the country as a cold front moves from the Ohio Valley to the East Coast today. An upper level trough of low pressure will pass east through the Great Lakes region later today and tonight.
A degree or two warmer Wednesday with highs in the lower to mid 90s after humid morning lows in the mid 60s to near 70. The upper ridge currently northwest of the FA will slowly push southeastward and flatten by late week. The West Texas Region will be close to the center of the upper ridge which is reflected in the temp forecast. Being close to the center of the upper high will allow little in the way of relief by rainfall.
The next disturbance comes to the area in the form of a backdoor cold front.
A trough develops over Lake Winnipeg 00z Thu. Mainly focused on an upper trough that will bring showers and thunderstorms late Wed night into Thu night, and also took a close look at the July 4th weekend. Looks like a good shot at showers and thunderstorms associated with that upper trough late Wed night into Thu night, but no severe weather is expected. Dry air and high pressure will bring clear skies and dry weather through the TAF period. A cold front crossing later Thu into Thu night will bring NW winds to 20 kts into Fri, strongest over the east half. Winds will diminish to less than 15 kts late Fri into Sun as high pressure moves across.
250 PM MDT TUE JUN 28 2016 he upper level high center will be along the western CO border tonight, and is expected to shift a bit eastward on Wed. Showers and thunderstorms will again develop over and near the higher terrain by late morning. Light, southeast upr flow is expected to result in slow moving storms that generally stay close to the higher terrain.
123 PM EDT TUE JUN 28 2016 A reinforcing cold front moves through today. Cooler for the remainder of the week. Previous discussion Upper level trough moving through during the short term, but behind the cold front moisture should be somewhat limited.
240 PM CDT TUE JUN 28 2016 Northwest upper level flow continues over the central US with a seasonal hot ridge extending from the Four Corners Region north into the Canadian Rockies.
High pressure builds in for Wednesday. Cooler for the remainder of the week. High pressure builds in for Wednesday. Previous discussion Upper level trough moving through during the short term, but behind the cold front moisture should be somewhat limited.
402 PM CDT TUE JUN 28 2016 Warming trend into Wednesday as a cold front approaches from the north resulting in increasing clouds and a chance for showers and storms. On the synoptic scale the northwest flow pattern across the northern Plains and upper Midwest will continue through mid-week due to a ridge over the Rockies and a longwave trough over Appalachia. A cold front will approach from the north Wednesday, but not before warmer air can advect in from the west ahead of the front result in a slightly warmer day. Winds will also be breezy especially along the international border just ahead of the cold front, out of the west-southwest at 5-10mph with gusts to 15-20mph due to deep mixing. Isolated to scattered thunderstorms are expected Wednesday afternoon along and ahead of the cold front approaching from the north.
243 PM CDT TUE JUN 28 2016 At H5 strong high pressure over desert southwest with ridge extending into western canada. Gulf of Alaska low sending waves underneath ridge over the Pacific Northwest. Trough over the Great Lakes. Ridge pushing east today into the northern and central plains with temperatures about a category higher over yesterdays highs. Precipitation continuing through the night with warmer over night lows in the 60s.
332 PM EDT TUE JUN 28 2016 An upper trough will move east of the region this evening as high pressure builds in from the upper Great Lakes.
A complex of thunderstorms will develop across the high Plains tonight and then drift east-southeast through the overnight hours. Eastward extent of any convection will be limited by western edge of high pressure and drier over the eastern Ozarks, so will confine probabilities to southeast Kansas and western Missouri. Temperatures and humidity levels will remain on the comfortable side throughout the day Wednesday, with highs ranging from the lower 80s across the eastern Ozarks to the upper 80s in portions of southeast Kansas.
1222 PM CDT TUE JUN 28 2016 Thunderstorms have developed early this morning across south central NE/north central KS in the vicinity of an elevated cold front that stretches from northern KS into central MO.
