541 AM EDT Sun Aug 13 2017 An area of low pressure currently resides over northern North Carolina this morning stretching a stationary boundary southwestward across the deep south. Closer to home, an Atlantic ridge of high pressure continues to control the sensible weather elements across the Florida Keys this morning, with a weak pressure pattern in place, winds are light and variable across the service area. Temperatures are steady in the lower 80s for most island communities this morning, with dewpoints seasonable in the middle 70s. The the aforementioned ridge of high pressure will continue to strengthen, while additional pockets of moisture stream in from the east.
630 AM EDT Sun Aug 13 2017 A cold front will settle into NC this morning, where it will then stall and remain quasi-stationary through the middle of the upcoming week. Muggy lows again in the lower to middle 70s. Generally persistence temperatures in the middle to upper 80s, with perhaps some lower ones over the nrn Piedmont (on the "cool" side of the front), and with still muggy lows in the lower to middle 70s. The upper level pattern will be characterized by high pressure over the deep south and weak cyclonic flow over and north of Central NC.
343 AM CDT Sun Aug 13 2017 A high pressure center over the Great Lakes will continue to influence weather conditions across the area today and tonight. Initially easterly winds will gradually veer and become southeasterly today as the high pressure center shifts eastward. The southerly component to the wind direction should help afternoon high temperatures rise a few degrees warmer than yesterday. The persistent trough that had been in place for the past couple of weeks over the northeastern CONUS will break down and be replaced by upper-level ridging.
An impulse moving over the top of a mid/upper ridge extending from the central Gulf coast into Texas was producing convection across the Red River Valley region early this morning. Some decrease in convection coverage is likely as the work week progresses as ridging aloft increases and becomes centered for a time over the central Gulf coast region.
534 AM EDT Sun Aug 13 2017 High pressure and an associated pool of deep dry air will drift east from the Midwestern states, and cross the commonwealth late today and tonight.
SHORT TERM (Now through Monday): 500 mb high pressure over Deep South Texas and the Rio Grande Valley today and tonight will yield to a weak inverted 500 mb trough that will briefly develop over the western Gulf of Mexico on Monday.
405 AM EDT Sun Aug 13 2017 Gradual drying today, behind last night's cold frontal passage, will result in increasing sunshine by this afternoon. Monday, as aforementioned high pressure moves to the east coast, a southerly low-level flow will bring an expanding cumulus field into at least our Finger Lakes zones of CNY. Scenario continues with a trof over the Great Lakes, weak high pressure over the area, and deep moisture and convection off to the south.
Northerly winds have allowed some slightly drier air to filter in with dew points in the northwest in the low 60s and mid 60s around the Nashville metro. Highs will reach into the low to mid 80s with dew points along and north of I-40 in the low to mid 60s.

The cold front is now to the south and east of the forecast area. 7 inch range with the higher values across the mountains.
1051 PM PDT Sat Aug 12 2017 A cold front will move across the region overnight through early Sunday morning. The cold front is moving onto the west coast. /Nisbet 06Z TAFS: A cold front is knocking on the Cascades door.
220 AM MDT Sun Aug 13 2017 Upper trough over the Dakotas early this morning will shift slowly eastward this afternoon. It does appear that by mid to late afternoon, the low level flow will turn more easterly especially over southern parts of SE WY and this combined with the weak mid level impulse nearby will likely set off scattered thunderstorms once again.
429 AM EDT Sun Aug 13 2017 High pressure will settle across the region today, lowering humidity and bringing increasing amounts of sunshine.
Otherwise, with the high pressure overhead, drier southerly winds should prevail. Decks should lower possibly become MVFR around 09-12Z but keep things scattered out for now as forecast soundings and short term guidance are lacking moisture due to upper level ridging.
340 AM EDT Sun Aug 13 2017 A cold front will continue to move farther offshore and south of the area today, but begin to stall into the early part of the week. High pressure will build across the area tonight into Monday.
623 AM EDT Sun Aug 13 2017 High pressure builds in today and shifts offshore on Monday. Weak low pressure passes to the south Monday night.
433 AM CDT Sun Aug 13 2017 The latest upper air analysis and water vapor imagery shows flat ridging extending acrs southern TX and the northern Gulf coast. A disturbance was translating east acrs the Red River valley on the northern periphery of the ridge, producing a large convective complex that is traveling along a west to east oriented quasi- stationary frontal boundary acrs northeast TX/southeast OK into southern AR and northern LA. 24 Little change to the fcst for the upcoming week as flat ridging will persist acrs the northern Gulf coast. By the middle to latter part of the week, ridging is expected to build some over the region. Aftn temperatures will run close to seasonal normals through the week with highs in the lower 90s, outside of any areas that see cooler temps from showers.
Latest models bring surface cold front and upper trough through our CWA faster today than they did yesterday morning. Showers will shift south and east this evening to southeast Oregon and most of southern Idaho, as the first north Pacific upper trough of the approaching fall season comes in. The surface cold front will stall along the Nevada border and will be the focus for more showers in southern areas overnight and Monday. Winds will become northwest 10 to 20 mph this afternoon and evening in the cooler air behind today's cold front.
527 AM CDT Sun Aug 13 2017 Another quiet and pleasant day on tap, as high pressure slowly drifts east across the Midwest.

Temps wl be a few degrees cooler than Mon due to cld cvr and showers expected. This is lkly due to EC weakening the ridge while GFS and CMC maintain it's strength. Cold front will approach Tue with showers and tstms possibly affecting terminals north of BGR with localized MVFR conditions.
332 AM EDT Sun Aug 13 2017 07Z water vapor and H4 RAP analysis shows a weak upper level ridging pattern over the Gulf of Mexico and Florida peninsula. subtropical ridge axis lies over the far southern Florida peninsula and into the SE Gulf of Mexico. This position is providing a general light SW flow pattern in the lower levels across our region. The low level pattern will not change much through Monday as the subtropical ridge remains generally just to the south of of Fort Myers and provides a weak SW flow onshore to the Florida west coast. furthest removed from the ridge axis.
The low pressure system responsible for all the shower and thunderstorm activity will linger into Sunday morning with precipitation chances across the eastern CWA through a good chunk of the afternoon. The period begins with a weak upper level ridge crossing the region with dry conditions expected. By Monday night, an upper level trough and surface frontal boundary will begin crossing the region.
336 AM EDT Sun Aug 13 2017 A cold front will cross the region Today with another round of showers and thunderstorms, followed by high pressure on Monday. A cold front will cross the State Today. Weak high pressure will move across the region tonight with clearing skies. Temps wl climb abv normal into the lwr 80s for interior Downeast and u70s acrs the north with H8 temps warmer than Sun. Temps wl be a few degrees cooler than Mon due to cld cvr and showers expected. This is lkly due to EC weakening the ridge while GFS and CMC maintain it's strength.

115 AM EDT Sun Aug 13 2017 High pressure will extend across the area through the first half of the week.
1232 AM CDT Sun Aug 13 2017 Very pleasant weather conditions to continue tonight and Sunday as high pressure, currently stretching from Lake Superior south to northern Illinois, will drift slowly off to our east through Sunday. High pressure is keeping mild and quiet weather in place for the weekend in the Midwest. Overnight, winds light and variable as the ridge remains anchored in the region.
412 AM EDT Sun Aug 13 2017 Gradual drying today, behind last night's cold frontal passage, will result in increasing sunshine by this afternoon. Monday, as aforementioned high pressure moves to the east coast, a southerly low-level flow will bring an expanding cumulus field into at least our Finger Lakes zones of CNY.
Highs will once again climb into the lower 90s with heat indices ranging from 100-105.
404 AM EDT Sun Aug 13 2017 A cold front will settle into NC this morning, where it will then stall and remain quasi-stationary through the middle of the upcoming week.

256 AM EDT Sun Aug 13 2017 Low pressure will drag a trailing cold front through New England this morning with drier air working in during the day.
As parent low and upper vort max swing northeastward into Canada, showers transition off the high terrain and onto the Plains while the surface front slows and lags across the Rosebud-Sheridan County line by morning.
Monday should be mainly dry as weak 500mb ridging moves in behind the departing short wave. Therefore, once again temps will be warmer across the north.
While areas along and west of a line from Albany through Panama City may see convection initiated along this trough, most areas will get their storms from an over-active land breeze/seabreeze each day. Highs will be in the lower 90s with heat indices around 100 degrees.
548 AM EDT Sun Aug 13 2017 High pressure building into the region will result in VFR conditions for most of the forecast. Winds will be 5 knots or less under this high with mainly only mid or high clouds passing over. Model soundings and plan views do however suggest the development of weak instability Mon afternoon, primarily in the vicinity of Saginaw Bay and the higher terrain in north central Lower Mi.
222 AM EDT Sun Aug 13 2017 A cold front will settle into NC this morning, where it will then stall and remain quasi-stationary through the middle of the upcoming week. Then between 06 to 12z, the arrival of the cold front into the area from the north- northwest will result in a continued chance for showers and storms, primarily north of highway 64. Mild overnight lows in the lower to mid 70s. The sfc cold front will stall in vicinity of highway 64 as it becomes parallel to the flow aloft. Thereafter, guidance suggests central NC will be situated at the southern periphery of the westerlies, on the northern periphery of an upper level ridge progged to amplify over the Deep South.
Cold front is moving onshore in Washington and northern Oregon with some light precipitation as mid and high level clouds are already pushing east of the Cascades. The front is expected to bring some light precipitation across the forecast area as it moves through Sunday morning, followed by gusty winds and cooler temperatures. A cold front will begin moving through the area Sunday morning.

Also, an approaching trough will start digging into northern Nevada and Utah keeping most precipitation to our west.
406 AM CDT Sun Aug 13 2017 High pressure over the southern Great Lakes continues to extend surface ridging over the region this morning which helped keep the MCS over Nebraska from entering our area. This high will shift south today weakening this ridge and allowing a more southerly flow to develop over the region.
349 AM PDT Sun Aug 13 2017 An upper trough to the north of the region will strengthen and move toward the region through Monday, bringing a cooling trend, with temperatures below normal by Monday. Below normal temperatures will continue across the area through mid week as the trough moves little.
A broad upper level trough will remain over the western US through Monday. High pressure will then build into region bringing warming and drying conditions to northwest California. Monday's forecast is similar to today's, but high temperatures for the interior region will be a few degrees cooler.

350 AM EDT Sun Aug 13 2017 Upper flow is relatively zonal across the Ohio Valley this morning, with a deep trough located over the Northern Plains. The afternoon looks quiet under partly cloudy skies, with temps warming into the low to mid 80s. This will likely result in warmer lows across southern KY.
351 AM CDT Sun Aug 13 2017 A flattish upper level ridge persists across much of South Texas this morning with a weak short wave trough scooting east on the periphery of the ridge over extreme North Texas. The upper level ridge will bring more heat to the region and upper 90's are again expected. Will again have to monitor for a Heat Advisory but at this time, looks like heat index values will be a degree or two cooler than todays values.
130 AM EDT Sun Aug 13 2017 A cold front moves through the area tonight followed by high pressure building in for Sunday and Sunday night. Weak high pressure remains over the area Monday and Monday night as low pressure passes to the south, then southeast of Long Island.
/issued 337 PM CDT Sat Aug 12 2017/ Mid-level trough and an associated MCV were making steady progress across our Rolling Plains' counties this afternoon ahead of a distinct layer of subsidence. Barring some lingering showers off the Caprock early Sunday and a few afternoon storms near the NM state line, much of the day looks to be uneventful as transient upper ridging overspreads the area. This story should hold until Sunday evening when the next trough in westerly flow arrives from the Colorado Plateau. This results in mean troughing over the western CONUS through the week and weak cyclonic SW flow locally.
A trough of low pressure moving across far northern California on Monday will result in brief cooling early in the week.
655 AM EDT Sun Aug 13 2017 A weakening cold front will stall across North Carolina today. then will push back north tonight into Monday as a wave of low pressure moves along the boundary.
The high resolution models offer very little help in how the short-term forecast will evolve having not captured the current activity properly.
A wave of energy ahead of an approaching cold front continues to produce light showers and some breezy winds across mainly western Montana this morning. The cold front is still expected to move into central Idaho and northwest Montana later this morning, and through west-central and southwest Montana by this afternoon. Showers and thunderstorms will become more numerous through this afternoon with the cold front. Thunderstorms are most likely along the Continental Divide southward into southwest Montana, where the passage of the cold front best aligns with afternoon heating.
305 AM PDT Sun Aug 13 2017 A developing trough of low pressure near the West Coast will bring stronger onshore flow with dry southwest to west flow aloft.
418 AM EDT Sun Aug 13 2017 A cold front has moved/transitioned to our southeast. Otherwise, high pressure passing to our north behind the front will be our dominant influence today and tonight, bringing fair weather. The high will move to our east on Monday and winds around it will start to carry moisture back northward. Aloft, a strong high pressure ridge will remain nearly stationary over the Deep South and Gulf Coast through the majority of the extended. A deep upper level low over eastern Canada will keep a troughing pattern in place across much of the northeast conus, becoming less amplified across the Ohio Valley due to the ridging just to our south.
626 AM EDT Sun Aug 13 2017 High pressure over the Midwest will move slowly east over the next couple of days providing fair weather.

Cold front remains well off to the northwest of the area at 07Z stretching from northwest Minnesota across eastern South Dakota and into northwest portions of Nebraska. Short range models bring the cold front into northeast Nebraska by 12Z with a continued chance of thunderstorms in advance of the front from south central Nebraska into southwest Iowa through the morning and early afternoon as front continues to work its way south to the Kansas border by late this afternoon. More significant convection with potential for heavy rain will be possible tonight as storms focus on the quasi-stationary boundary near the Kansas border and a mid level trough moves into the region helping to enhance vertical motion.
219 PM CDT Wed Jul 12 2017 Main challenge is southward movement of a cold front into and across Kansas the next couple of days which will impact temperatures and convective chances over the area.
454 PM MDT Wed Jul 12 2017 Upper level analysis shows nearly zonal flow over the northern plains, with slight ridging over the northwestern CONUS. The upper ridge will begin rebuilding over the western CONUS Thursday, persisting into the weekend.
High pressure has been trying to move back west into the Great Basin and by Thursday afternoon/evening expect to see some limited amounts of unstable air slipping into the South Central Highlands for a few afternoon thunderstorms.
/issued 329 PM CDT Wed Jul 12 2017/ Seasonably hot weather is expected to continue the next few days as an elongated mid-level ridge remains in place. Scattered thunderstorms are expected to develop along a cold front across Kansas by Thursday afternoon.
Temps have warmed into the lower 90s per 20Z metars across most of the region, though locales across portions of central LA only managed to warm into the middle to upper 80s, given ensuing showers and thunderstorms. The aforementioned weak shear axis is progged to lift northward to across the Red River Valley area tomorrow, whilst UA ridging centered near the Four- corners region has its eastern periphery nose in across portions of east TX. Flow aloft will commence to veer from near zonal to northerly by the end of the week, courtesy of the UA ridge amplifying across the Four-corners region whilst shifting a bit eastward.
