311 PM CDT Fri Oct 28 2016 We are in the midst of a warm and breezy afternoon with 1940Z temperatures mostly in the lower to middle 80s. This warmth was being supplied by a strong late-October upper level ridge that was dominating the region. The ridge will flatten modestly over the coming 24 hours as a weakening storm system traversing the Great Basin emerges across the northern High Plains. Even as the ridge flattens it will still hold sway over West Texas, and although mid- level heights will fall ever so slightly, an increase in the downslope component of the winds coupled with a slight uptick in 1000-500 mb thicknesses and progged 850 mb temperatures all support even warmer temperatures on Saturday.
Lows will remain mild in the mid 60s over the interior to the lower to mid 70s along the coast south of the Cape. High pressure will drop across the Carolinas with pressure gradient tightening and supporting breezy to windy east flow.
403 PM CDT Fri Oct 28 2016 Upper ridging planted over western Texas has influenced this recently benign and warm weather pattern so. with this ridge's eastern expansion over East Texas.
Increased south winds are expected on Saturday, with the higher speeds and gusts at KABI. /issued 406 AM CDT Fri Oct 28 2016/ (Today and Tonight) Upper level ridge of high pressure to remain in control across the Southern Plains, with quiet weather across West Central Texas.
339 PM EDT Fri Oct 28 2016 A ridge of high pressure will continue to build into the region overnight. Ridging at the surface and in the upper-levels will remain present for most of the period which keep us dry and warm.
The combination of the existing drought conditions, with the stronger ridging aloft, will bring heights higher aloft and will support near record high surface temperatures through the upcoming weekend.
Medium Lingering influence of low level thermal ridge axis will be in place across the area during the morning.
138 PM CDT Fri Oct 28 2016 As of 18 UTC, a secondary cold front was propagating south through the US Highway 2 corridor. This compared to highs in the lower 70s south central with filtered sunshine and mixing ahead of the aforementioned front in an airmass characterized by 850mb temperatures on the 00 UTC NAEFS ensemble mean in their 97. The 00Z ensemble and deterministic models are projecting progressive flow aloft through the period, as a series of mid/upper level troughs propagate across North Dakota. On Saturday high pressure moves in at the surface; though aloft a sagging low pressure system over the eastern Northwest Territories will bring cooler Canadian air into the state.
353 PM CDT Fri Oct 28 2016 Latest WV imagery and UA analysis shows dry air over the area with upper ridging building east toward the area.
A transitory ridge of high pressure is moving through the Northern Rockies causing skies to clear and temperatures to warm slightly. The ridge moves eastward putting the region back in southwesterly flow. Snow levels appear to remain above pass level so only the highest peaks will receive accumulating snow.

340 PM CDT Fri Oct 28 2016 Weak frontal boundary which had been stalled across nrn MS/AL/GA has for the most part diminished, with high pressure over the mid/srn Atlantic basins now beginning to strengthen into the region. Temp trends across much of the area have warmed into the lower 80s, and these may climb a couple of more degrees before the afternoon hrs are done. Latest model suites are not deviating much from past thinking, with the subtropical ridge xpcted to strengthen even more over the SE states as it drifts further toward the s. Weak upper ridge pattern will also makes its way ewd across the nrn Gulf states through the weekend period, helping to maintain the warm/stagnant pattern. The upper-level ridge will continue to drift east as we head back into the beginning of the work week.
103 PM CDT Fri Oct 28 2016 The main forecast concern in the short term period is the strength of the wind today ahead of the approaching cold front, and how warm temepratures will get before the front arrives. Early this morning, an area of low pressure at the surface was in place across the Dakotas advancing slowly east with time. This low will continue east today and tonight, with the cold front sweeping across western MN late afternoon, through western WI tonight. Winds will turn southwesterly during the day with widespread speeds of 15-25MPH and gusts around 30-35 MPH in far southern MN and along the Buffalo Ridge.
254 PM CDT Fri Oct 28 2016 Cooler temperatures on Saturday highlight the short term forecast. The 12 UTC global and high resolution suites are in agreement on cool high pressure building across western and central North Dakota tonight into Saturday.
229 PM EDT Fri Oct 28 2016 High pressure returns tonight through Saturday.
and looks to persist through the period ahead of an area of high pressure aloft that will expand E into the region by early Saturday. /issued 1015 AM CDT Fri Oct 28 2016/ Upper ridge continues to increase its influence across the srn CONUS.

140 PM EDT Fri Oct 28 2016 A weak cold front will move through Eastern North Carolina today.
330 PM EDT Fri Oct 28 2016 Mostly cloudy skies will slowly break apart this afternoon as high pressure moves into the region. An area of ridging at mid-lvls and high pressure at the sfc will briefly nudge into central ny tonight keeping NEPA and central NY dry.
/ISSUED 319 AM CDT Fri Oct 28 2016/ Upper level ridging will be in control of our weather through the weekend, leading to another stretch of dry and unseasonably hot conditions across the region. IR satellite imagery this morning shows plenty of high-level moisture cresting around the northern periphery of this area of high pressure, and these high clouds will invade through the day. In terms of fog potential this morning: while we can't rule out a few of our cooler locations experiencing some visibility reductions this morning, any coverage looks to occur on a very limited basis, which precludes any mention in the worded forecast at this time. Late tonight, a jet streak will emerge out over the High Plains which will result in lee cyclogenesis across western Kansas.
155 PM EDT Fri Oct 28 2016 Aviation High pressure will bring fair weather today but the chance for rain will return by late tonight and Saturday as low pressure tracks north of Lower Michigan.

257 PM CDT Fri Oct 28 2016 It was sunny and warm across the Mid-State early this afternoon, with 2 pm temperatures ranging from the middle 70s into the lower 80s. Models are still consistent with the solution of building a high pressure ridge out of Texas and Oklahoma across the lower Mississippi Valley and into the Tennessee Valley over the next 24 hrs.
407 PM EDT Fri Oct 28 2016 High pressure will build over the area through Saturday before dropping south.
1244 PM CDT Fri Oct 28 2016 A few record or near record high temperatures are expected today and Saturday with breezy southwest winds within the low/mid level thermal ridge where highs will climb into the mid and upper 80s.
1132 AM MDT Fri Oct 28 2016 Current surface analysis shows low pressure over southeast SK, with warm front extending southeast through the central and eastern Dakotas. A cold front extends southwest from the low across MT into southern ID. Upper level analysis shows ridge axis over the high plains, with low pressure remaining off the west coast. Warm weather will continue across the area today, before cold front to the northwest sags south across the area later today and tonight. A little snow could mix in across the highest elevations of the Black Hills late tonight/early Saturday. Cooler air in place with the clouds will keep highs only in the upper 40s to mid 50s.
216 PM MDT Fri Oct 28 2016 Upper level analysis has broad ridge across the central CONUS with giant upper low off the west coast. Cooler air in place with the clouds will keep highs only in the upper 40s to mid 50s.
Surface wise, our area remains between a massive area of high pressure to the north and lower pressure in the northwest Caribbean sea. Within the maritime northeast to east flow, high temperatures will average in the lower to mid 80s with overnight lows in the mid 70s. See no reason to stray from isolated climo pops with average high temperatures in the lower to mid 80s and overnight generally in the mid 70s through the period.
142 PM EDT Fri Oct 28 2016 High pressure will prevail through the weekend.
1247 PM CDT Fri Oct 28 2016 High pressure over the Ohio Valley will move eastward into the Mid Atlantic States.
201 PM EDT Fri Oct 28 2016 Lake effect showers will slowly wind down this afternoon as high pressure moves into the region. Regions that will see a few breaks in cloud coverage Friday night will see temps falling into the lower 30s, while areas where cloud coverage manages to hold, will remain in the upper 30s. As the low moves from NE Ontario into Quebec a cold front will begin to approach the area by afternoon bringing increasing clouds and some scattered showers. Low late in the pd will bring cooler air and a chance for shwrs. Ridging over the eastern CONUS slowly starts to strengthen and high pressure as the surface starts to build.
An upper level ridge anchored over the southwestern states will keep a hot and dry west to northwest flow over the area today. A degree or two cooler today following yesterday's weak short wave trough then back up to yesterday's temps on Friday.
An upper level trough will take shape across the region for the next several days. Highs will be in the upper 80s to mid 90s range, with lows hanging out in the low/mid 70s. Towards the very end of the forecast, the ridge currently located near the 4 corners area will begin to build eastward which would lead to a slight increase in temps and decrease in overall rain chances.
Strong mid level ridge just east of the area will continue subsident hot and dry airmass over the region today. 47 inches which is in the lowest 10 percent of all soundings for the date and not much above the lowest PWAT of 1. The low level ridge extends from Treasure coast into the NE Gulf with a late day sea breeze collision expected from near Lake George SW toward wrn Orange county. Winds to 10 knots expected around the Atlc ridge becoming SE around 10 knots near the coast this afternoon.
This, combined with a deep thermal low over the Lower Colorado River, will lead to a surge within a day or two.

Scattered afternoon thunderstorms over the higher terrain Flagstaff southeast to the New Mexico border.
1227 PM EDT THU JUL 28 2016 A wave of low pressure traveling along a slow moving frontal boundary will produce heavy rainfall mainly in southern locations today and tonight.
/issued 434 AM CDT THU JUL 28 2016/ SHORT TERM (Today through Friday): Water vapor imagery shows lingering moisture associated with weak mid level troughing across the region. precip may become more isolated in nature given that high pressure will be expanding back into the region. with the high pressure coming back into play.
A low pressure area across western TN will move to the northeast and increase showers and storms in the afternoon.
Temperatures today should climb to mid 90s and lower 100s across the lower elevations with 80s to lower 90s mountains.
640 AM CDT THU JUL 28 2016 Scattered convection continues across mainly southwest and eastern sections of the state as an upper level low lifts out. Activity is resulting from the weak upper low and associated trof axis currently located along the Mississippi River.
Weather map shows weakening pressure gradient over the NW Gulf as high pressure builds eastward across the northern Gulf. Low pressure trof axis aloft much less defined this morning, generally over SE TX/LA. This cause the mid/upper trof weaker and less defined, but displaced further north today, and a weak sfc trof over the arklatex expected to generate convection later this morning. DML SE to S winds 10-15 kts and seas 2-3 ft expected today and Friday, diminishing a bit by the weekend as as high pressure becomes established over the northern Gulf of Mexico. Scattered showers and thunderstorms will continue today as general low pressure weakness aloft remains over the region.
This, combined with a deep thermal low over the Lower Colorado River, will lead to a surge within a day or two. Strong high pressure over northwestern Arizona will weaken during the same time frame as low pressure moves into the Pacific Northwest.
isolated to widely scattered) as there isn't any significant lifting mechanism expected (outside of the higher terrain). With the NW flow in place, storms should mainly be confined along and SE of the higher terrain and mainly across central Montana.
1253 PM EDT THU JUL 28 2016 Low pressure will move northeast across the Ohio Valley region today and tonight.
The upper low responsible for the rain over the last day or two is now well removed from Arkansas, residing practically over central Kentucky as of 11am this morning. Scattered convection continues across mainly southwest and eastern sections of the state as an upper level low lifts out. Activity is resulting from the weak upper low and associated trof axis currently located along the Mississippi River.
1007 AM EDT THU JUL 28 2016 Continued Hot with limited rain chances as High Pressure Ridge just east of JAX over the coastal waters remains in place. The low level ridge axis has shifted just slightly southward from yesterday and extends across Central Florida from DAB, to north of MCO and Tampa. The East Coast Sea Breeze will move inland just in time to keep the beaches topping out in the lower/middle 90s.
A weak warm front is forecast to lift northeast today across southwest Kansas.
Radar mosaic clearly showing the upper trough axis along the spine of the MS river this morning. This evening, the trough axis should be nearing the spine of the Appalachians and therefore, the widespread coverage should be exiting the Plateau.
636 AM CDT THU JUL 28 2016 12Z TAF Cycle An upper high will build back to the east today and Friday allowing for the upper flow to transition to more northerly and northwesterly across the Panhandles. /Issued 436 AM CDT THU JUL 28 2016/ Upper level analysis reveals 597 dam ridge of high pressure centered over the desert southwest.

In the Middle and upper levels (700-200 mb), latest available ir imagery overlaid with model streamline analysis as of 800 am detail a well aligned middle and upper anticyclone centered near 31. Out to the west of that feature, the axis of a inverted upper level trough is aligned along the 92 meridian and bisects the Western Gulf of Mexico. As of 800 am, skies are mostly cloudy across the Florida Keys and immediate adjoining Florida Bay, immediate Nearshore Gulf waters north of the Middle and Lower Keys, Hawk Channel, and waters west of the Lower Keys. Temperatures outside of rain cooled showers are in the lower 80s with dewpoints in the middle to upper 70s. Moderate ridging will remain in place this afternoon and skies will become mostly sunny again with temperatures reaching back up to near 90 degrees.
636 AM CDT THU JUL 28 2016 An inverted trough over western Wisconsin will shift south today, while high pressure over south central Canada will slowly approach the Northern Plains and western Great Lakes region.

756 AM EDT THU JUL 28 2016 A wave of low pressure traveling along a slow moving frontal boundary will produce thunderstorms with heavy rainfall mainly in southern locations today and tonight.
541 PM MDT Fri Apr 7 2017 Upper ridge axis over the central high plains today will shift eastward by Saturday with southwest flow aloft replacing it. At the surface, trough will move out of northeastern Colorado tonight ending up near a McCook to Gove line by Saturday afternoon. West of the trough, southwest winds will increase in the afternoon and dew points will fall due to downsloping.
1145 PM CDT Fri Apr 7 2017 Broad upper level ridging building into the central U.
840 PM EDT Fri Apr 7 2017 An upper level trough will gradually lose its grip on the area on Saturday.
Temperatures should drop quickly the rest of the evening into tonight, with many areas especially along and east of I-65 outside of the Nashville urban center falling below freezing. However, satellite imagery shows considerable cirrus approaching from the northwest, and this may keep parts of western zones from reaching freezing tonight.
/Issued 323 PM CDT Fri Apr 7 2017/ South winds have returned this afternoon in response to strengthening westerlies over the Rocky Mountains, resulting in warmer temperatures today, and a milder night expected for tonight.
850 PM EDT Fri Apr 7 2017 Low pressure in the Northeast States and high pressure building across the Lower Mississippi River Valley will cause dry northwest flow over the region, and breezy winds this evening.
/issued 642 PM CDT Fri Apr 7 2017/ 00Z TAFS High pressure centered directly overhead this evening will result in continued light and variable winds overnight. Winds will turn southerly by mid morning Saturday as the high shifts to the east. /issued 324 PM CDT Fri Apr 7 2017/ Just some thin high clouds passing over the area today with temperatures this afternoon in the low to middle 70s. This will cause the lower levels to moisten a bit along with a warming trend into the weekend.
911 PM EDT Fri Apr 7 2017 Low pressure over the New England States will continue lifting north as cold high pressure centered over the Lower Mississippi River Valley builds east into our area.
Latest surface analysis shows that the ridge axis has moved into Illinois, and the RAP shows it continuing to move east overnight. Coldest lows will still occur over the eastern counties where the current temperatures are the coldest and the winds are the lowest compared to central MO where winds will increase through the night. Nwly winds will gradually diminish this afternoon and evening and become sly as the ridge axis passes. With expected temps in the upper 30s and dewpoints in the lower 30s, believe frost will be more difficult to develop. Otherwise, with sly winds increasing on Sat and thermal ridge pushing 10C to 12C 850mb temps into the area, expect temps to reach the 70s.
1001 PM EDT Fri Apr 7 2017 Low pressure over New England will continue to move rapidly northeast away from the area this evening. This will allow a ridge of high pressure to build toward Ohio from the lower Mississippi Valley overnight.
720 PM MST Fri Apr 7 2017 A Pacific low pressure system and associated front will swing into the western states this weekend resulting in strengthening winds Saturday. Precipitation chances will be focused across the northern half of Arizona with no precipitation expected in the lower deserts.
928 PM EDT Fri Apr 7 2017 High pressure will settle in the Ohio Valley tonight and move east Saturday night.
829 PM EDT Fri Apr 7 2017 With clearing skies, diminishing winds, early evening temps only in the lower to mid 50s and dew points (where still mixed) in the lower to mid 20s, have lowered forecast mins to the mid to upper 20s in the coldest valleys. Mostly clear skies are already in place across the southwest part of the forecast area and high pressure building east from the MS valley will bring clearing skies to the remainder of the area tonight. With the ridge axis just moving over us later tonight should not have too much of a ridge valley temperature difference though. With high pressure shifting east of the area Saturday afternoon a significant warming trend will begin. The ridge valley temperature split for Saturday night is not something the blended data used for initialization handles very well.
Dry high pressure will continue to build slowly into the area as a weak cool, reinforcing boundary slides southward down the peninsula late. High pressure ridge over the deep south will only slide slowly to the east as trough aloft over the eastern seaboard shifts gradually offshore.
1255 AM EDT Sat Apr 8 2017 An upper level trough will gradually lose its grip on the area on Saturday.
1240 AM EDT Sat Apr 8 2017 High pressure for the weekend.
926 PM MDT Fri Apr 7 2017 We have decided to leave the high wind warning for Arlington and the Laramie in tact during the next 18hrs. We did lower wind speeds a bit tonight except in the wind prone area of Arlington where the high wind warning remains in effect. Southwest flow aloft strengthens as a weak cold front also passes west to east across our counties. Shower chances will continue west of a Douglas to Laramie line along the cold front and baroclinic band, otherwise dry.
