In the middle and upper levels (700-200 mb), Latest IR imager overlaid with model streamline analysis as of 300 am depict the center of a middle and upper warm core anticyclone over SE Louisiana with an attendant ridge extending eastwards to across North Florida to about 33 North 70 West. To the southeast of that feature, a TUTT (Tropical Upper Tropospheric Trough) cell is located over the SE Bahamas and continuing to slowly migrate very slowly westwards. Latest CIMMS analysis from the University of Wisconsin illustrates amplE dry air upstream in the lower to middle levels upstream of the Florida Keys to the longitude of Eastern Cuba and the SE Bahamas, averaging about 1. Temperatures across the islands are generally in the lower to mid 80s with dewpoints in the middle to upper 70s.
140 AM EDT SAT AUG 6 2016 High pressure will build across the Great Lakes through the weekend allowing cooler and much drier air to overspread the area.
408 AM CDT SAT AUG 6 2016 Early morning surface analysis with IR satellite imagery identified a ridge of high pressure along the eastern Dakotas up through Manitoba, which matched up with the clear skies and light winds. This high pressure system will move very little over the next 36 hours, which means that the sensible weather of sunny skies and light northwest winds will continue.
231 AM EDT SAT AUG 6 2016 A cold front will result in showers and a few isolated thunderstorms overnight followed by dry and less humid weather for the rest of the weekend. Scattered to numerous showers are expected to continue overnight ahead of an approaching cold front.
A weak cold front will sag into the area during the period.
Dry high pressure will remain at the sfc through Saturday, before shifting across Minnesota on Sunday.
346 AM CDT SAT AUG 6 2016 A broad area of high pressure will bring quiet weather conditions through the weekend.
reaching the high plains Saturday morning. Warmer temperatures on Sunday as mid level temps warm in association with an upper ridge that will move across the region.
This as PWATs climb near to above 2 inches, high freezing levels, and reasonably slow storm motions. Showers and storms will be on the increase toward dawn with approaching cold front.
Low to mid level moisture will continue to increase across the western Gulf of Mexico into eastern Mexico even as the 500mb ridge across the south central United States continues to provide subsidence across the state. With the increase in surface dewpoints across the lower Rio Grande valley today.
1057 PM PDT Fri Aug 5 2016 A deep and slow moving low pressure system will move into the area over the next few days. This low will bring cooler temperatures and the threat of showers and thunderstorms.
325 AM PDT SAT AUG 6 2016 A cooling trend over central California will continue through the weekend due to a series of dry low pressure systems impacting the region.
346 AM EDT SAT AUG 6 2016 A cold front will be east of the area this morning. High pressure will build southeast out of Canada over the weekend.
302 AM EDT SAT AUG 6 2016 Shower and thunderstorm chances will continue until a cold front completes its passage this morning. High pressure will bring dry and less humid weather for the rest of the weekend. Shower and thunderstorm potential is expected to continue this morning with the approach and passage of a cold front. Coverage should be isolated to scattered, outside of a broken line associated with a pre frontal trough advancing across southwest PA where likely POPS were maintained. Building high pressure should bring a clearing trend with lowering humidity levels after frontal passage.
210 AM PDT SAT AUG 6 2016 A trough of low pressure near the West Coast will bring dry southwest flow aloft with near seasonal temperatures.
423 AM CDT SAT AUG 6 2016 (Today and Tonight) Hot and dry conditions will persist across West Central Texas again today, with high pressure dominating.
355 AM CDT SAT AUG 6 2016 Today should be a less humid day under light nthrly flow with a slow clearing trend as the cold front that came thru yesterday continues to slowly drift S.
751 PM EDT Fri Oct 28 2016 High pressure sliding east equals a warm up for the area this weekend.
917 PM EDT Fri Oct 28 2016 High pressure returns tonight through Saturday.
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.
1043 PM EDT Fri Oct 28 2016 High pressure sliding east equals a warm up for the area this weekend.
751 PM EDT Fri Oct 28 2016 A warm front will move across the forecast area Saturday.
911 PM EDT Fri Oct 28 2016 High pressure returns tonight through Saturday.
The associated trailing cold front was seen in the 18Z objective surface analysis from central MN into western SD. A prefrontal trough extended from southeast SD into central NEb as well.
715 PM EDT Fri Oct 28 2016 High pressure will build across the area through the weekend with above normal temperatures.
Associated surface cold front will move through the local area Saturday morning with a wind shift to the northwest but no precipitation.
/ISSUED 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.
Southerly flow to develop tonight in the wake of a warm front.
905 PM EDT Fri Oct 28 2016 Dry weather and slightly warmer low temperatures are expected overnight. Saturday will be much warmer with increasing clouds.
18Z surface data has in inferred warm front running from roughly KMCW to a little east of KSTL. A cold front will enter the far northwest area just prior to sunrise. On Saturday, the cold front will slowly move south through the area. Cooler, drier air advecting into the area on north winds behind the dissipating precipitation band should allow temperatures to cool into the mid and upper 40s north, while the south holds in the mid and upper 50s.
Latest surface analysis places a cold front extending across the central plains with a trough across western KS and eastern NM. Have increased cloud cover in the grids to account for dense cirrus spilling over the upper ridge.
Also modified the low temperatures tonight in and near the base of the foothills. Over the mountains cloud cover will increase through the evening as an approaching trough will bring a slight chance of showers to the mountains mainly north of I-70 and the Park range. The plains will stay dry but increasing clouds overnight will keep low temperatures in the lower 50s. Temperatures for Saturday will be cooler with passage of a weak front with highs in the mid 70s and 40s in the mountains. (Saturday night through Friday) Issued at 220 PM MDT Fri Oct 28 2016 the strong high pressure ridge responsible for the dry and unseasonably warm weather of the past several days is projected to weaken midweek with the passage of a weakly organized upper trough tethered to a closed low over the nrn Baja Peninsula.
851 PM EDT Fri Oct 28 2016 High pressure will build over the area through Saturday before dropping south.
The combination of the existing drought conditions, with the stronger ridging aloft, will increase heights higher aloft and will support near record high surface temperatures through the upcoming weekend.
943 PM EDT Fri Oct 28 2016 A warm front will move across the forecast area Saturday.
Coverage will increase going into the evening and overnight hours as an upper level disturbance works across the region, though the higher terrain will be favored. Temperatures will be quite a few degrees warmer than last night under cloudy skies.
945 PM EDT Fri Oct 28 2016 High pressure will prevail through the weekend.
Lows should range from the mid and upper 50s near the Indiana state line to the lower 60s west of I-55 in areas of stronger warm advection. Warm and windy for tonight and into tomorrow morning as the Midwest is between an exiting high pressure, and a developing storm system well to the northwest. Saturday night will see low pressure advancing across Illinois which will help pull a cold front south into central Illinois.
Along with the cooler air, the models all show low clouds encompassing the cwa into Saturday morning. The main issue during this time period will be the short wave trough coming in from the southwest along with good frontogenesis. With the cool air, clouds, and rainfall expect Saturday's highs to only be in the mid 40s to the lower 50s across the region.
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.
The low clouds never scoured out in a finger from Cando to Grand Forks to Thief River Falls to Hallock. Therefore in this finger the warmer temps expected today will probably not be realized. Just to the south of the highway 2 corridor, the clouds did scour out and temps will probably reach their expected highs. Finally, with steady and cooler northwest winds tonight, not anticipating fog to cause any problems like it has done the last couple of days. Much cooler for Saturday highs. The second half of the weekend will bring upper ridging and quiet weather back to the region.
Winds will die down this evening as the low moves into the area. Saturday night, Some light lake effect rain showers northwest may be possible as colder air (850 mb temps to near -2C) move in with nnw flow behind a cold front.
742 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 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.
Southerly winds 5 to 10 kt overnight will increase to around 15 kt on Saturday as low pressure deepens in the Central Plains.
830 PM MST FRI OCT 28 2016 Dry weather with mostly clear skies will return this weekend, with desert temperatures continuing in the lower 90 degree range.
Warm and dry weather is expected to start the weekend as High pressure east of Indiana allows pulls warm southerly breezes into the state.
Low clouds and patchy fog is beginning to form over portions of the Lower Columbia Basin and adjacent valleys.
806 PM EDT Fri Oct 28 2016 Dry weather can be expected through Saturday as high pressure builds across the area.
1231 AM EDT Sat Oct 29 2016 High pressure will prevail through the weekend.

Dry and mild conditions will persist into the weekend as a broad mid- level ridge shifts eastward over the area. These breezy southerly winds will support decent warm-air advection overnight with low temperatures only dropping into the lower 60s. Another unseasonably mild day is expected on Saturday with temperatures rising within a few degrees of record conditions with highs in the low/mid 80s. These southerly winds will begin to diminish during the mid/late afternoon hours as a cold front moves into central Kansas. Period starts off with a cold front moving southeast across the CWA Saturday night as a upper level trough moves across the Northern Plains.
A cold frontal passage will occur on Saturday. GFS H7 temperatures fall from 8-10 deg C at 00z this evening to between 2-5 deg C thru 18z Saturday, but expect to see a little more sunshine tomorrow so the high temperature forecast is tricky. Generally expect highs to be at least a few degrees cooler, but especially over the northern panhandle as clouds remain intact per moisture fields.
/issued 354 PM CDT Fri Oct 28 2016/ (Tonight and Saturday) The upper level ridge over the Southern Plains and Texas will remain in place tonight and Saturday, with quiet weather expected for our area. Until then, a very dominate upper ridge will maintain dry conditions, along with temperatures above seasonal normals. Models this cycle continue to bring an upper trough into the southern Rockies by late week; the resulting southwest flow aloft, ahead of this trough, will enhance rain chances for mid to late week. In addition, the GFS and ECMWF indicate a weak cold front may push into our counties, from the north, late week; this too will enhance rain chances.
1120 PM EDT Fri Oct 28 2016 Dry and milder than normal weather can be expected into Saturday as high pressure builds across the area.
/EC/ Tonight through Saturday, Unseasonably warm conditions will continue into Saturday with high temperatures likely a degree or so warmer than will be the case this afternoon. There should be enough moisture in the lowest layers of the atmosphere (at least south of I-20) to instigate some patches of fog, particularly down in southeastern MS along the Highway 98 corridor.
811 PM EDT Fri Oct 28 2016 High pressure returns tonight through Saturday.
The Florida Keys will be located between a large area of high pressure over the Carolinas and a broad area of low pressure north of the coast of Honduras overnight.
/Issued 320 PM CDT Fri Oct 28 2016/ Strong ridge in place through the central U.
Water vapor satellite imagery and RAP 500 mb height analysis show an upper level low translating westward across the western Gulf of Mexico, while an upper level ridge of high pressure meanwhile extends from west TX and eastward across much of the Deep South. Temperatures are generally ranging in the lower to mid 80s, with readings even approaching 90 around Greenville as of 3 PM CDT. Upper level ridging will continue to stretch across the southern and southeastern U. Lows tonight are forecast to range from the lower to mid 50s across most inland locations to around 60 to the mid 60s along the immediate coast and beaches. Highs Saturday should range from the lower to mid 80s along the immediate coast to the mid to upper 80s over the interior.
A weak upper level ridge of high pressure is transitioning eastward across the Central Plains. Near the surface, a lee side trough of low pressure remains anchored from southwest Nebraska into west central Kansas. This will initially allow the lee trough to deepen across the High Plains tonight into early on Saturday with a closed circulation forming over eastern CO into northwest KS. Essentially, the arrival of this wave and associated cold front will bring nothing more than a wind shift as a dry boundary layer keeps any risk for precipitation well north and west of Kansas.
Ceilings and visibility finally improve once the low moves close enough to turn winds from southeast to southwest. Unfortunately, behind the low the northwest flow is going to sweep more low clouds back over the area from the northwest, supported by the stratus already over over northwest Minnesota. Models are in general agreement Saturday night with high pressure building into the area. However, there are some minor differences in the QPF early in the evening in regards to the upper level long wave trof moving through.
A cold front will move through tonight, which means Saturday will be cloud, cool, and breezy.
Ridging aloft and at the surface allowed for another day of well above avg temps this afternoon as the dry and warm weather continues to dominate. Ideal radiational cooling conditions will persist tonight, however the boundary layer has been a little slower to decouple tonight compared to last night, thus combined with the warmer temps will help to keep overnight lows at or slightly above what we saw last night. /issued 628 PM CDT Fri Oct 28 2016/ Tonight through Saturday, Unseasonably warm conditions will continue into Saturday with high temperatures likely a degree or so warmer than will be the case this afternoon. There should be enough moisture in the lowest layers of the atmosphere (at least south of I-20) to instigate some patches of fog, particularly down in southeastern MS along the Highway 98 corridor.
With some sct ci patches moving NW to SE across mid state region atop of upper level ridging influences, and with short term models continuing this trend, updated sky conditions for tonight to moclr across entire mid state.
This will initially allow the lee trough to deepen across the High Plains tonight into early on Saturday with a closed circulation forming over eastern CO into northwest KS. Essentially, the arrival of this wave and associated cold front will bring nothing more than a wind shift as a dry boundary layer keeps any risk for precipitation well north and west of Kansas.
Despite the high to the east, a decoupling of winds aloft from the surface has resulted in mainly calm conditions locally. Night time lows should cool into the low/mid 50s, or 5-10 degrees above seasonable norms. 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.
High pressure strengthening a bit to our north combined with broad low pressure in the northwest Caribbean will keep a fresh east breeze across the coastal waters.
Dry conditions will persist for most of western Washington tonight, but another trough of low pressure will lift northward across the area on Saturday bringing a return of showers over the area.
Low-level ridging to the east of Texas and mid- to upper-level height ridging over west Texas with warm, dry air through the 925-700mb layer is aiding in well above normal temperatures this afternoon. SREF probabilities of lower cloud ceilings and fog are much higher Saturday morning than this morning and this should keep low minimums warmer than this morning where greater radiational cooling took place.
945 PM EDT Fri Oct 28 2016 High pressure will extend across the Carolinas through the weekend.
Models continue to portray rain developing across the southwest later this evening, spreading east and slightly north overnight as forcing aloft associated with the right entrance region of an upper level jet and an embedded mid level impulse coincide with a surface cold front pushing south across the region. The cold front will also bring much cooler air for tomorrow with highs Saturday 20 degrees colder than today for my southern 1/2 counties. 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.
Some gusts have been into the 20-30mph range with the higher gusts along and west of the I49 corridor. Overnight lows will remain warm with many locations staying in the lower 60s. Guidance has been a bit cooler with high temps as of late. An upper level disturbance/cold front will near the area, however, the front will weaken as it gets near the area.
Lows tonight will again remain some 3 to 6 degrees above normal for this time of the year with lows falling into the lower 60s across the Nature Coast, and mid to upper 60s central and south.
00 UTC surface analysis shows an area of high pressure across Southeastern Georgia. Winds across our region have generally gone calm with temperatures falling through the lower 70s. Aloft, ridging continues to build in across the region, with a fairly dry airmass above 850 mb. With high pressure in control, expect it to be a quiet night with mostly clear skies and temperatures falling into the upper 50s to lower 60s.
906 PM EDT Fri Oct 28 2016 A warm front will move across the forecast area Saturday.
The ridging to our south and southeast will continue to dominate through the weekend, but the surface gradient will tighten up a little as a cold front hangs up over the Upper Midwest and Great Lakes. Have bumped temps up solidly into the lower 80s, and look for dewpoints to mix down into the lower 50s.
/issued 348 PM CDT Fri Oct 28 2016/ WV imagery this afternoon shows the upper ridge as the dominant feature across much of the CONUS, centered over W TX, but extending nwd into the Midwest.
703 PM EDT Fri Oct 28 2016 High pressure will extend across the Carolinas through the weekend.
640 PM CDT Fri Oct 28 2016 A flattening ridge is over most of the CONUS with a strong southward pushing low positioned over Hudson Bay at 700-500mb while there is a trough situated from the Northern Plains to the Panhandles at 850mb. Minor forecast challenge - Timing of the cold front for Saturday which would adjust the winds and potentially high temperatures mainly in the northern part of Kansas.
619 PM CDT FRI OCT 28 2016 Warm and windy for tonight and into tomorrow morning as the Midwest is between an exiting high pressure, and a developing storm system well to the northwest. Saturday night will see low pressure advancing across Illinois which will help pull a cold front south into central Illinois.
Aloft, heights are recovering across the lower and middle Mississippi Valley, thanks to a ridge centered across southwest Texas. A quick-moving short wave trough is moving east across south central Canada. Eastern Kentucky remains under the influence of high pressure, with mostly sunny skies and temperatures ranging from the mid to upper 60s in the northern half of the area, to the upper 60s to lower 70s across the southern half of the region.
