544 AM EDT Wed Oct 11 2017 Crossing low pressure will bring occasional showers to the area through tonight. Light rain chances will continue Thursday before the low dissipates. Low pressure and its associated warm front should continue to track out of the Midwest today. The low is progged to track to SW PA during the afternoon as an upper trough approaches with continued rain chances, though a model progged dry slot could limit precip coverage. Models show some limited instability S of the low, so mentioned a slight chance of afternoon thunderstorms south of PIT.
458 AM EDT Wed Oct 11 2017 Currently - Deep layered ridging extends from the Atlantic, across the extreme southeastern United States, into the Gulf of Mexico. Forecast - The tight pressure gradient between the ridge to our north and the approaching wave will maintain moderate to fresh breezes across the area over the next few days. Ridging will still dominate today into tonight. The trough will begin moving through the Florida Keys area tonight, bringing with it increasing deep layered moisture and increasing convergence along surge boundaries and confluent flow.
An upper level trough will bring cool temperatures to the area today along with mainly clear skies.
1204 AM CDT Wed Oct 11 2017 For the ArkLaTex, NW flow to about 5kft in the wake of this morning's cold frontal passage then SW flow 15-25KTS into flight levels. Look for more SKC toward dawn perhaps and no issues with mist or fog as air will be quite dry with fresh high pressure moving into the area. Current temperature trends are following the forecast fairly well, ranging from lows in the mid 50s across the interstate 30 corridor to the lower 70s elsewhere.
343 AM CDT Wed Oct 11 2017 Ridging will continue as the upper level high over the Gulf coast builds back to the west. Upper level flow will back over the next few days bringing warmer air to the area.

243 AM MST Wed Oct 11 2017 Weak high pressure will bring warmer conditions today with highs in the low to mid 90s across the lower deserts. The synoptic pattern will keep a deep trough situated well to the north allowing dry southwesterly flow aloft to remain over the Desert Southwest through the weekend. A slight boost in temperatures will take place today over yesterday as a weak ridge axis exits to the east.
Frontal passage will bring cooler temperatures but short-lived for today and tonight before increasing once again for the latter part of the week.
232 AM EDT Wed Oct 11 2017 A 3-day stretch of cooler and cloudy weather begins today with periods of rain and drizzle.
Upper level ridge bridging westward across northern old Mexico will pull warmer air back into the area, with downslope enhancement leading to above normal high temperatures by Thursday, though with typically wide diurnal swing for early fall still Thursday morning.
Tonight Through Thursday A cold front is currently moving ESE through the state. The cold front was located from near Batesville. Expect the low clouds over NWRN and WRN sections of the area to persist into the early evening hrs before conditions improve slightly. The low clouds may persist a bit longer across the NRN counties this evening into the overnight period. temps across all of the CWA will be considerably cooler than in recent days.
317 AM PDT Wed Oct 11 2017 A trough of low pressure will settle over the area today through Thursday bringing cooling and higher humidity inland with morning and nighttime clouds from the coast to portions of the inland valleys. High pressure will rebuild late in the week for warmer, drier weather and more Santa Ana conditions over the weekend. WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO Water vapor loop shows a longwave trough over the western U.
210 AM EDT Wed Oct 11 2017 Canadian high pressure will generally be in control of our weather through the end of the work week.

This front will bringing variably cloudy conditions tonight and usher in cooler, more fall-like temperatures for Wednesday with highs mainly in the 50s.
405 AM MDT Wed Oct 11 2017 Upper level analysis has ridging over the central CONUS with a strong trof entering the Pacific Northwest. At the surface, lee trof is located across central Montana into northeast Wyoming with temperatures at 4am mainly in the 40s. Warmer air will continue to build into the area today, ahead of an approaching cold front. Surface lee trof will produce breezy south-southwest winds in some areas today, especially across parts of northeast WY and south central SD. A cold front will cross the area late tonight and Thursday morning, bringing much cooler air for the latter part of the week.
A fairly tranquil pattern under high pressure. Temperatures will drop to below freezing again tonight for some more morning frost. Temperatures will be on the increase as warmer air advects into the region on Wednesday with dry conditions for the remainder of the week. A mid-level ridge will move from the Upper Midwest and south-central Canada to the northeastern US and eastern Canada early in the period. If not for the cloud cover, the forecast would probably be much warmer.
237 AM EDT Wed Oct 11 2017 Low pressure over the Ohio valley this morning will move east slowly to be near the mid Atlantic coast Thursday. Eventually, this high will suppress the low and associated rain to the south and push drier air into the region beginning tonight and continuing into Thursday. In the big picture, high pressure centered over eastern New England early in the period will move east with time allowing a SW flow to once again usher in unseasonably warm air by this weekend along with mainly dry conditions.
Dry and warm conditions can be expected today with high pressure over the region and southwest flow aloft. Winds will remain breezy along the western foothills as southwest winds increase ahead of an approaching Pacific cold front. Cold front will move through this evening/tonight bringing a wind shift to the west and northwest and rain and mountain snow showers behind the front. High temperatures in the 60s to 70s can be expected today, with highs in the 40s and 50s for Thursday behind the cold front.

336 AM CDT Wed Oct 11 2017 With low pressure and its associated cold front east of the area, high pressure is forecast to build into the region over the next 48 hours. This will result in mainly dry conditions along with much cooler temperatures. With low level moisture trapped beneath a strong mid level inversion, the low stratus is likely to stick around across much of the region through tonight. It will take a shift in low level winds to the south on Thursday to finally scour out the low level grunge. Consequently, highs today will struggle to reach the lower 60s in many areas.
Cooler and Cloudy Today. The combination of deep moisture in place and the formation of a weak coastal trough will continue to produce isolated to scattered showers for today, mainly along the coast. Rain chances will linger tonight and Thursday due to the weak coastal trough and low to mid level moisture. Temperatures will be below normal today due to abundant cloud cover and slightly cooler air filtering into the region. The cooler temperatures today will be short lived as above normal temperatures return for Thursday.
A cold front, currently draped southwest-to-northeast over southeast Oregon, will continue its path east, arriving in southwest Idaho this morning and the Magic Valley this afternoon. Light valley rain and mountain snow will spread along and behind the front, mainly across the mountains, Baker County Oregon through Valley County Idaho; the highest peaks look to receive about an inch of snow. Other impacts today include breezy west to northwest afternoon conditions as flow aloft mixes to the surface and maximum temperatures 10 to 15 degrees cooler than they were yesterday. Cold air will continue to stream into the region Thursday as the associated upper level trough continues to deepen. Temperatures will decrease even still, by 2 to 5 degrees, Thursday as snow levels drop to about 4000 to 5000 ft MSL ahead of the next cold frontal passage.
1202 AM CDT Wed Oct 11 2017 An upper low is centered over west central IL this evening promoting scattered showers and thunderstorms mainly north of I-70 and west of I-57 as it swings northeastward. Very minimal amounts of instability are associated with the low this far northward, however strong effective bulk shear has produced a few strong but low topped storms producing strong wind gusts and small hail this evening.
306 AM EDT Wed Oct 11 2017 Canadian high pressure will generally be in control of our weather through the end of the work week. A dry cold front across southeastern Ontario and southern Quebec this afternoon will move southward through the North Country tonight.

A low pressure system will move across the Pacific Northwest today as an associated trough of low pressure moves across California. Cooler air and an increase in wind will be the main affects of the trough passage. Water vapor imagery shows one area of mid and mainly high clouds moving to the east of the forecast area as an area of low pressure moves onshore in Oregon and Washington. A trough of low pressure assoicated with the low is moving onshore in Northern California. 9um imagery shows the marine layer clouds pushing well into the coastal valleys to the west of the forecast area and this is a harbinger of cooling conditions for the Central California Interior as the cooler coastal air pushes through the passes.
with a trailing trough axis extending across north-central Illinois. Due to cloudy skies and a cool W/NW flow, temperatures will be considerably cooler than in recent days. with overnight readings remaining in the lower to middle 50s.

217 AM EDT Wed Oct 11 2017 Low pressure over the Ohio valley this morning will move east slowly to be near the mid Atlantic coast Thursday. Eventually, this high will suppress the low and associated rain to the south and push drier air into the region beginning tonight and continuing into Thursday. Any left-over showers early Thursday morning should be suppressed south toward central and southern Pa during the day as the high builds southeast. Temperatures will be near normal with highs mainly in the lower to mid 60s. Clear cool weather is expected Thursday night as the high builds down the east coast.
An upper ridge located generally over the northern Plains will continue downstream of northeast Montana today. As this shifts eastward, upper level southwest flow will prevail today as a trough over the Pacific Northwest deepens and begins to move into Montana. A cold front associated with the upper level trough will approach the region tonight and Thursday, with south to southwest surface winds switching to the west and northwest and increasing with the frontal passage. Winds will begin to decrease Thursday night as the low pressure center moves downstream of our CWA.
Much of these low clouds are expected to erode later this morning and the rest should pull away as trough continues to move off to the northeast.
410 AM EDT Wed Oct 11 2017 Cold front moves in later today.
527 AM CDT Wed Oct 11 2017 High pressure on the surface and aloft will dominated the weather pattern across the Four State Region for the rest of the work week and into the weekend. This morning the upper ridge of high pressure was centered along the Gulf Coast and over South Mississippi, Alabama, and Northwest Florida and was flat and elongated from Mexico across the Gulf Coastal States and off the Southern Atlantic Coast off Georgia and the Carolina/s. During the weekend the upper ridge will shift East while remaining along the Gulf Coast and off the Central and Southern Atlantic Coastal region as our next significant trough of low pressure amplifies South across the central sections of the country.
647 AM EDT Wed Oct 11 2017 Low pressure will track east through northern Ohio today and stall in northeast Ohio and western Pennsylvania tonight. A trailing cold front will slowly drop south through the Ohio Valley tonight and early Thursday.
1211 AM CDT Wed Oct 11 2017 The surface front and low pressure had made its way through/east of the region this afternoon though lingering low stratus and mist/drizzle was still occuring for some locations. Overnight temperatures area expected to fall into the lower 40s across the region with some locations across western Missouri and southeastern Kansas seeing a few upper 30 readings. Cloud cover will slowly improve from southwest to north east through the day Wednesday with highs only reaching the lower 60s.
126 AM EDT Wed Oct 11 2017 Crossing low pressure will bring occasional rain to the area through Wednesday night. Low chances for light rain should continue Thursday before the low dissipates. Rain chances should increase overnight as low pressure and its associated warm front track E out of the Midwest. The low is progged to track to SW PA during the afternoon as an upper trough approaches with continued rain chances, though a model progged dry slot could limit precip coverage. Models show some limited instability S of the low, so added a slight chance of afternoon thunderstorms south of PIT. Heights will build Thursday afternoon/evening leading to an overall reduction of PoPs and cloud cover west of the Ridges, while easterly flow holds in the cloud cover and low-level moisture on the eastern slopes.
406 AM EDT Wed Oct 11 2017 Cold front moves in later today.
626 AM EDT Wed Oct 11 2017 High pressure off the Southeast Coast will circulate moisture into the forecast area today.

Maintained likely to categorical POPs, with the highest from PIT and points N where the best omega and upper support is progged. The low is progged to track to SW PA during the afternoon as an upper trough approaches with continued rain chances, though a model progged dry slot could limit precip coverage. Models show some limited instability S of the low, so mentioned a slight chance of afternoon thunderstorms south of PIT.
/issued 319 PM EDT Tue Oct 10 2017/ High pressure will remain over the Southeastern United States for the rest of this week, as an upper level low near Puerto Rico moves west northwest and into South Florida region.
Large scale troughing in the upper levels has dug south into the Pacific Northwest, and will gradually slide east over the next few days. As the trough axis slides over head, we will see another round of precipitation today, mainly west of the Cascades and north of the California/Oregon state line, and breezy to gusty afternoon winds across the East side.
1056 PM PDT Tue Oct 10 2017 A cold front will arrive tonight with breezy winds. Cooler and showery weather can be expected for much of the work week as an upper level area of low pressure settles over the Inland Northwest.
Low level warm air advection will keep the low clouds intact over southern WI on Thursday.
346 AM CDT Wed Oct 11 2017 Cold front has made its way into the area.
156 AM MDT Wed Oct 11 2017 Main issue will be the low temperatures tonight. Will be warmer with plenty of sun but the warmup will be tempered by lack of downslope component and the recycled cool air.
440 AM EDT Wed Oct 11 2017 A 3-day stretch of cooler and cloudy weather begins today with periods of rain.
306 AM CDT Wed Oct 11 2017 There is an upper ridge centered over the SE US with an upper trough over NW US.

The boundary is likely to drift across the area and be offshore just to the south of the forecast area by late tonight, when slightly cooler and drier air will filter into the region. Lows tonight be cooler, ranging from the lower 60s over interior northwest to lower 70s interior southeast and along the coast.
1028 AM CDT Wed Sep 13 2017 High pressure centered over the plains this morning has resulted in a light wind regime across the area. Warmer areawide temperatures mostly in the mid to upper 80s across eastern Oklahoma and west central Arkansas with lower 80s elsewhere are expected.
High pressure will return to our region during the weekend. This evening will be predominantly dry with weak high pressure in control ahead of the last stage of the remnants of Irma. High temperatures Thursday will be lower 80s mainly east of I-95, near 80 along and just east of the Blue Ridge, and mid to upper 70s west. The chance for lingering rain showers exist Thursday evening before a quiet period Thursday overnight arrives as the low slides to the east. Low temps Thursday night will be cooler than Wednesday night.
637 AM CDT Wed Sep 13 2017 Very weak upper impulse southwest of KLBB will continue to the southeast with upper level ridge building slowly in the next 24 hours.
Highs today should generally be in the upper 70s to lower 80s though locations along the immediate lakeshore that stay under the clouds longer will be cooler. For tnt, some of the low level moisture from the remnants of Irma will spread into se WI.
745 AM EDT Wed Sep 13 2017 Remains of Irma were located in the vicinity of West TN this morning as it was part of a broad trough over the lower MS Valley. The better moisture associated with the weakening cyclone should remain over northwest GA. Temperatures should recover some today and will be warmer on Thursday.
/issued 340 AM EDT Wed Sep 13 2017/ Mid level ridging will hold east of Florida today and Thursday as a deep trough lifts from the southern Mississippi River Valley into the northeastern CONUS. At the surface, weak high pressure will continue to build across the area through Thursday. Dry air is continuing to work into the region on the southern side of the trough, which will keep rain chances rather limited once again today. However, as the trough lifts away on Thursday, moisture will gradually increase, allowing for more scattered to numerous storm coverage. Hurricane Jose and associated upper trough features to remain in the Western Atlantic through mid week.
A low pressure system off the central California coast will bring a threat of afternoon and evening showers and thunderstorms to much of the district through Wednesday night.
Low ceilings, relatively light winds, and patchy fog are present with temperatures as of 3 AM CDT in the lower 60s at most locations. Highs today are anticipated to moderate into the lower 70s west of the Mississippi River but remain in the middle 60s near the Tennessee River. Models indicate mid/upper level ridging will gradually build into the Lower Mississippi Valley for the remainder of the week into the weekend. CJC 12Z TAFs GOES IR and surface analysis showed the weak low level circulation of tropical cyclone Irma centered just north of MEM at 11Z.
Low pressure is currently centered near the TN/MO/KY border, with the mid and upper level system nearly stacked aloft. Light rain will continue off and on into tonight, as the lowest levels become saturated and the mid and upper level low pressure system will be closest to us. This could lead to fog development on the ridges.
616 AM CDT Wed Sep 13 2017 Region remains under the influence of a weak upper-level ridge axis which extends from the Four Corners region north/northeast into the High Plains. In addition, a closed upper low is just moving onto the California coast. CAM's continue to weaken this activity as it moves east, away from the low-level jet so have left our forecast area dry through the day.
The increased cloud cover over Southern Arkansas and North Central/Northeast Louisiana should keep temperatures a few degrees cooler in these areas compared to locations farther west, where temperatures are already near 80 degrees F. Irma continue to wrap moisture back down through much of the lower and middle MS Valley. UA ridging across the western CONUS will commence to shift eastward today, courtesy of an UA trough moving onshore across the Pacific northwest. With an UL ridge drawing near and clearing skies occurring today, both 500 mb height fields and 850 mb temps will be on the rise leading to temps in the 80s today, followed by seasonal avg temps by tomorrow /upper 80s to lower 90s/. Expect further warming by this weekend /lower 90s CWA-wide/, courtesy of the UA ridge moving almost overhead.
