510 AM EDT SUN JUN 5 2016 Moisture will increase ahead of an approaching cold front.
247 AM CDT SUN JUN 5 2016 07z/2am surface analysis shows cold front advancing eastward toward the I-57 corridor. Further west, a cooler/drier airmass will arrive across central Illinois, with dewpoints dropping into the middle to upper 50s nearly everywhere by mid afternoon. Yet another wave will dive southeastward around the prevailing upper trough over Ontario/Quebec on Monday.
334 AM CDT SUN JUN 5 2016 Clouds should be exiting our eastern counties this morning once mid lvl trof slides east of the region by around noon. Rest of the day looks to bring plenty of sunshine and warm temperatures as mild high pressure works in from the west. The high will stay in control through Monday, with temperatures moderating up into the mid 80s during the afternoon. Front will be moisture starved in the lower levels, but mid level ascent forced by an approaching short wave may result in isolated showers/possibly a rumble or two of thunder Monday night as the front passes.
331 AM CDT SUN JUN 5 2016 An upper level trough extending from the upper Midwest southward through the mid MS river valley will lift northeast across the Great Lakes States. A broad upper level ridge was located across the western US. Highs will reach the lower to mid 80s.
341 AM CDT SUN JUN 5 2016 A large upper level low center will shift from the northern Great Lakes to the southern tip of Hudson's Bay today/tonight with and upper level northwest flow in place over our region.
230 AM MDT SUN JUN 5 2016 With ridging and drier air mass pushing into the region, the main issue will be temperatures. Models in close agreement on low level thermal field and tended to blend the output or slightly below the warmer guidance.
Anticyclonic northwest flow aloft is in place over the central High Plains to the east of a strong upper level ridge sitting over the western CONUS. With light winds and dewpoints in the mid 40s tonight, we should see lows drop into the lower 50s with a few locations likely dipping into the upper 40s. This will push a cold front across west central and southwest Kansas Monday afternoon and evening. The upper ridge also moves east with westerly to southwesterly flow aloft developing over the central High Plains. Temperatures will also be warming daily through the end of the week as the upper ridge moves off east.
523 AM EDT SUN JUN 5 2016 KBYX detects isolated showers over the Lower Keys, as well as over nearshore and offshore waters surrounding the Lower Keys. Temperatures are in the lower 80s.
305 AM MDT SUN JUN 5 2016 Strong upper ridging will remain across the wrn CONUS through the short term. Upper ridge will dominate the weather for the period, with temperatures well above average.
High level moisture was noted N of an upper low moving into central CA. Went slightly above blended guidance for highs today based on trends from yesterday and mixing to 700-600 mb, so had highs in the lower to mid 80s. Area will still be under the upper ridge tonight and any evening mountain convection will dissipate after sunset. The pacific upper low will be undercutting the ridge on Mon.
228 AM CDT SUN JUN 5 2016 At 230 am cdfnt/upper trof extended from the Great Lakes thru sern MO and into central TX. Radars were showing sct shra and a few tsra across portions of AL and mid/ern TN, ahead of the cdfnt/trof. Today, the above mentioned cdfnt/trof will slowly push across the cwa today and is progged to be out of the TN valley by 06z tonight. Ahead of this cdfnt/trof there will be the chc of more sct shra/tsra across the cwa. Tonight, with loss of daytime heating and the cdfnt/trof continuing to push E of the TN Valley, will continue to taper off pops.
Big picture, the combination of an amplified upper level trough over the Great Lakes and a low pressure system over Texas (the one that has kept that area rain-soaked the last several days) have worked together to really ramp up our rain chances the last couple of days. As we get into the day today, the upper low over the Great Lakes will finally start to get a push to the east helping to stretch out the front that is draped over the region and slowly push the bulk of the activity eastward.
416 AM EDT SUN JUN 5 2016 A plume of deep moisture will slide across the state today as a warm front lifts north across the region. coinciding with the arrival of a cold front and potent upper level disturbance moving out of the Ohio Valley.
The broad low pressure area will continue to affect South TX through the next 24 hours. An upper level low is analyzed east northeast of the area, just south of the upper Texas Coast. Showers and thunderstorms continue to rotate southward and southwestward around the upper level low.
A trough of low pressure over northern Nevada will provide a modest decrease in temperatures for Monday.
The low pressure disturbance near the California coast will move inland today and is expected to be over western Nevada by this afternoon. Moisture will increase across this area on Monday as the low tracks towards Northeastern Nevada.
Upper ridge remains in place over the northern Rockies while an upper low develops over eastern Canada. Canadian high pressure slides into the Northern Plains on Monday with a slight drop in temperatures.
842 AM CDT Thu Oct 27 2016 A very mild October morning across the Tennessee Valley with temperatures already running in the lower to middle 60s in most areas. The latest surface analysis shows the "cold front" situated well to our north positioned from southern IL/IN into the Ozarks. To the south, the low level convergence is very weak and the overall push with the front is rather meager given the relative strength (or lack thereof) of the ridge north of the boundary. Current forecast max temps may be a tad on the cool side as newest ensemble output pushes us into the lower 80s this afternoon. The upper level ridge to our west will quickly build into the region during the overnight hours. The upper ridge will persist through the remainder of the short term period, as we move into the weekend.
Low level Atlantic moisture advecting into the region on a breezy northeast to easterly wind flow around the high combined with mid and high level moisture streaming in from the western Caribbean is supporting a fair amount of clouds across the forecast area early this morning. Despite the clouds though temperatures will again run above normal with highs climbing into the lower to mid 80s in most locations during the afternoon.
The upper level ridge axis will shift eastward across the area by mid week.
Anyhow did go a bit cloudier today and a bit cooler than prev fcst. Friday should be a mild day with mid 50s to mid 60s across the area as mild air is south of the low that will be moving along the International border.
/issued 347 AM CDT THU OCT 27 2016/ (Today and Tonight) An upper level trough that pushed a weak front into the area yesterday has moved off to the east. Upper level ridging will expand from the southwest back into our area.
The cold front that brought the showers/storms to central and southeast Illinois in the past 24 hours has just about exited our far southeast counties. Cyclonic flow and low level cold advection is expected to persist across the region for much of the day, but a progressive ridge of high pressure will shift across the region late today into tonight. Clearing should finally occur late in the day as the high pressure builds in.
This activity will slowly end from west to east as the low responsible for the activity pulls out of the region. The high will track east tonight, as a weak low tracks across the northern Great Lakes region on Friday. The southerly winds will also bring a much warmer airmass into the western Great Lakes as temperatures warm to well above normal levels.
Issued by National Weather Service Gray ME 854 AM EDT Thu Oct 27 2016 Weak high pressure will nose into the region from Canada today. Low pressure will move out of southern New England toward the area late tonight with precipitation developing from south to north.
assocd with upr trof situated along the MS RVR. and a few degrees warmer on Fri.
The low stratus has eroded overnight across much of the region. Much of southwest Minnesota into the Iowa Great Lakes will see the low stratus linger through the remainder of the morning, then lift in the afternoon as southerly winds increase. Cirrus clouds will also shift east this afternoon with upper level ridge axis arriving, allowing a great deal of afternoon sunshine in our west. Highs will range from the upper 50s near the Buffalo Ridge, to the mid/upper 70s in south central SD. Highs will be approaching 80 degrees through south central SD, tapering back to the lower to mid 70s along the I-29 corridor and eastward.
The 11 pm regional surface analysis showed a ridge along the Piedmont, providing light E-NE winds across our forecast area. Vapor imagery and upper air data showed a short wave trough translating eastward across the upper Midwest and mid South. The upper trough axis will be east of our region later this afternoon, when a general sinking motion will develop.
Above normal low temperatures can be expected tonight across central MO as an upper level ridge builds eastward into the area and surface/low level winds become southerly/southwesterly on the backside of the surface/850 mb ridge shifting east of the region. GKS Gusty south to southwest winds to prevail on Friday, so temperatures to warm up at least 10 degrees above normal most locations under mostly sunny skies, into the low 70s to low 80s.
An upper level ridge across the southwestern US will gradually shift east into the southern high plains Tonight. The high clouds moving southeast across the CWA at 200 AM should begin to Thin out after 400 AM and the patchy dense ground fog should increase in coverage across northeast and east central KS towards sunrise. Highs Today will reach the lower to mid 70s across northeast and east central KS, with mid to upper 70s across the western counties of the CWA.
a weak surface cold front had moved south into north central ND. A building upper level ridge and low/mid level warming with southwest winds aloft spreading from southwestern ND northeastward. Expect temperatures to climb into the lower 70s southwest. This low is forecast to move east into central ND by daybreak Friday. South winds ahead of the low and westerly winds behind it should keep the overnight low temperatures quite mild in the 40s.
1018 AM EDT Thu Oct 27 2016 High pressure will prevail through the weekend.
628 AM CDT Thu Oct 27 2016 Current GOES IR imagery showing the region engulfed in widespread stratus in the wake of low pressure over northern Indiana. GOES cloud thickness product indicating this stratus varying from 800- 1200ft thick, so not expecting any clearing overnight as a ridge of high pressure builds overhead by daybreak. With anticipated cloud cover, temperatures will suffer some with highs ranging from the middle and upper 40s along and northeast of I-94 to the lower/middle 50s elsewhere. Southerly winds pick up through the night tonight as low pressure moves into the Dakotas.
A Pacific low pressure system will bring showers and possible thunderstorms Friday.
Temperatures today will remain unseasonably warm, with highs ranging from the low to mid 80's, depending on the cloud coverage during the hours of peak heating.
Late mrng temps a few degrees warmer than yesterday and 12z sounding top of boundary layer also a few degrees warmer than 12z yesterday, so have raised daytime highs a couple degrees for most of the area as mid 80s will likely be achieved for most of LA/TX portions.
746 AM EDT Thu Oct 27 2016 Low pressure will bring rain to the region today. Warmer but unsettled weather is anticipated for the weekend. Surface cold front will slowly move through the area today. Cold advection behind the departing low pressure will be brief, but shower chances will continue tonight, mainly over the north and east. Some snow may mix in as well, especially north of I-80 and in the high terrain. High pressure will settle over the Ohio Valley Friday, with decreasing cloud cover as warm air advection ensures.
Cold front currently extending from ern Washington through central Oregon to near SFO will move east today supported by Pacific upper trough currently along 130W. Meanwhile, another Pacific upper low near 30/130W is advecting moisture northward into the frontal zone. Southeast winds 10 to 15 mph today ahead of the cold front, then light northwest behind the front. High temps today will be in the 50s in the mountains to mid 60s in the lower valleys, except near 70 in the western Magic Valley.
Strong high pressure over the region will lead near record temperatures today. A weather system moving through California on Friday will bring a chance of showers to southeast California along with slightly cooler temperatures. An unseasonably strong ridge of high pressure over the Desert Southwest has led to 500mb heights reaching 590dm (97-99% of climo) and 850mb of 22-24C over south-central and southeast Arizona. Looking upstream, a fast moving upper level low approaches California. The cirrus should stay thin enough not to impact temperatures today across the eastern half of Arizona, but may keep temperatures a degree or two cooler than previously forecast across southeast California and southwest Arizona. Heights aloft will drop across the Desert Southwest as the trough passes through California leading to a cooler day on Friday.
Weak cold front extends along the Ohio Valley and into northeast Arkansas. A record setting weather pattern will continue across the Mid- South over the next seven days as an upper level ridge builds over the southern United States. Highs will generally be in the low to mid 80s, with lows in the 50s and 60s.
712 AM EDT Thu Oct 27 2016 A weak cold front will push through the forecast area today. Have not mentioned SHRA in the TAFs given the low probabilities and scattered coverage.
739 AM EDT Thu Oct 27 2016 Low pressure over southern Michigan early this morning will track across Lake Ontario this afternoon. Milder weather will occur this weekend, as high pressure builds across the southeast states. A weak cold front from the upper Great Lakes may bring a chance of showers to the area for the later part of the weekend. As the low moves across the eastern part of Lake Ontario later this afternoon, that winds will shift more to the west, and the rain will taper to just a few showers. Downstream blocking should allow northern stream energy to phase with the lead trough and eventually result in a negatively tilted trough over the Northeast U.
A slow moving cold front will move across the forecast area today. The slow moving nature of the front means precipitation amounts will range from a tenth to a quarter of an inch of rain in the lower elevations and slightly more over the eastern mountains. However, precipitation amounts will decrease quickly post frontal so snow accumulations in the high mountains will be light.
526 AM MDT Thu Oct 27 2016 12Z TAF CYCLE A high pressure system will remain overhead today, then gradually shift SE of NM tonight and Friday as an upper level trough clips the Four Corners. Sheets of high clouds will be common areawide, and these will thicken on Friday as the ridge axis shifts SEWD. High pressure sliding over New Mexico will keep temperatures above normal through the weekend. These clouds will make it feel a bit cooler with filtered sunshine.

Upper level ridging is building into the region this morning.
648 AM CDT THU OCT 27 2016 The cold front that brought the showers/storms to central and southeast Illinois in the past 24 hours has just about exited our far southeast counties. Cyclonic flow and low level cold advection is expected to persist across the region for much of the day, but a progressive ridge of high pressure will shift across the region late today into tonight. Clearing should finally occur late in the day as the high pressure builds in.
1001 AM EDT Thu Oct 27 2016 Cold front crosses Thursday with showers.
1043 AM EDT Thu Oct 27 2016 Hydro Rain and snow showers will be ending this morning with fair weather through Friday as high pressure builds in.
The cold front is just entering our far northwest counties as of 08Z. The main issue for today is how long the low stratus will linger over the area behind the front. As a result went on the lower end of guidance for highs today.
KCSM/KLAW/KSPS are expected to be on the periphery of the lowest visibilities; however at least MVFR to IFR conditions are expected at these terminals.
/issued 332 AM CDT Thu Oct 27 2016/ Upper level ridge centered over Chihuahua will continue to edge northeastward toward our part of the state. Some high level cloudiness is making its way across the northern periphery of the high thanks to T. Despite the proximity of the high, temperatures will not get too crazy warm though they will be about 10-15 degrees above seasonal norms.
A high pressure cell in the lower levels, centered near the Carolinas, will remain stagnant today. Later this weekend, the high pressure will slowly edge back to the west, helping to loosen the surface gradient around South Florida and slightly weaken the east northeast winds.
High pressure ridging across the area from the NE will push east as a low pressure system moves through the Great Lakes region today and across New England region tonight as the trailing cold front weakens as it moves through the deep south and dissipates north of the state. High pressure behind it bridges across the boundary and builds into the area for Friday.
Texas will be under the influence of this near 590 dam western upper ridge going into the weekend. The upper level ridge out west will continue to build this way the next day or so. Still preferring the ECMWF in the extended forecasts - which is still pushing across a well-defined upper trof/low into the state from the west by next Tues/ Weds. Will also have to begin keeping track (with trends) for the next cold front, which is currently progged for next Fri. 41 High pressure over the eastern U.
1232 PM EDT Thu Oct 27 2016 Low pressure over lake Erie will move east dragging a cold front across the area by the afternoon. High Pressure will slide across the Ohio Valley on Friday. Another low pressure system will cross the Great Lakes over the weekend.
523 AM MDT Thu Oct 27 2016 Strong upper ridge will remain across the region today as the main axis crosses the CWA. In the low levels. southwest flow will today will bring warmer temps to the area along with dry conditions. Cooler air will gradually filter into the region through the day Friday with highs ranging from the mid 60s across northeast Wyoming to around 80 across south central South Dakota. A stronger cold front will approach from the north while an upper wave crosses Wyoming. The highest elevations of the Black Hills may see it transition to snow late Friday night. mean eastern pac troughing will support active/progressive sw flow over the region through the period, with split flow tendencies.
748 AM EDT Thu Oct 27 2016 Aviation Rain and snow showers will be ending this morning with fair weather through Friday as high pressure builds in.
Low pressure over northern Indiana and a trailing cold front across west central Indiana will move east across our region by midday today. High pressure over the upper midwest will move east across Indiana tonight. A mild southerly flow will develop on the back side of this high pressure system Friday as it moves on to the east.
Upper trough is currently working its way across the MS/OH River Valleys, and weak radar echoes are lined up pretty well with the trough axis. Another ridge will move in behind the trough for the remainder of the work week and into the weekend.
Surface wise, a massive ridge of high pressure extends from the entire eastern seaboard, down the Sunshine State while a trough of low pressure is lingering in the northwest Caribbean Sea.
959 AM EDT Thu Oct 27 2016 A cold front will cross the area this evening. High pressure then builds over the area tonight through Friday night.
Some of the high-res models guidance is showing some isolated showers west of I-35 this afternoon. Temperatures should warm up an additional degree or so from yesterday into the mid to upper 80s given reduced cloudiness, which should also allow low temperatures tomorrow morning to be a few degrees cooler than this morning in the upper 50s and lower 60s. The ridge will become centered over South Central Texas on Friday as it begins to weaken, allowing high temperatures to be similar to where they will be today.
The upper level ridge out west will continue to build this way the next day or so. Still preferring the ECMWF in the extended forecasts - which is still pushing across a well- defined upper trof/low into the state from the west by next Tues/ Weds. Will also have to begin keeping track (with trends) for the next cold front, which is currently progged for next Fri. 41 High pressure over the eastern U.
An upper level ridge will be over the area today with dry wsw flow aloft. At the sfc a lee trough will dvlp over east of the mtns. A ridge of high pressure will be centered over Texas on Friday as a weak upper trough moves into the central CA coast.
Good mixing in the boundary layer for this time of the year will result in highs in the 70's across most of southeast Wyoming to the low/mid 80's over western Nebraska and far eastern Wyoming.
1208 PM EDT Thu Oct 27 2016 A cold front will bring showers into the early evening, followed by dry and cool weather into Friday. Warmer but unsettled weather is anticipated for the weekend. Cold front now entering eastern Ohio with pre-frontal band of showers now beginning to cross the ridges. Still expect scattered showers with FROPA, while more significant rainfall will shift east of the ridges. Behind the cold front tonight brisk and colder in northwest flow behind the front. Cold advection behind the departing low pressure will be brief, but shower chances will continue tonight, mainly over the north and east. Some snow may mix in as well, especially north of I-80 and in the high terrain. High pressure will settle over the Ohio Valley Friday, with decreasing cloud cover as warm air advection ensures.
Gilchrist Previous discussion:upper level ridge and thermal ridge will be over Eastern Montana today. Mid and upper level moisture moving over the ridge will continue to bring cloud cover although there will be breaks at times today. The ridge axis moves to the east this evening turning the flow aloft to the southwest. Cooler and mainly dry weather will prevail on Friday with Northeast Montana between system.
High temperatures will reach the low/mid 80s inland with upper 70s at the coast. High pressure to the north will maintain an easterly flow over the waters.
705 AM EDT Thu Oct 27 2016 High pressure will prevail through the weekend.
A record setting weather pattern will continue across the Mid- South over the next seven days as an upper level ridge builds over the southern United States. Highs will generally be in the low to mid 80s, with lows in the 50s and 60s.
A weak upper trough was draped over central Alabama this morning. This trough was well ahead of the surface front that was back in the Missouri Bootheel. The main part of the trough lifts northeastward this afternoon. The upper level ridge axis will shift eastward across the area by mid week.
