Longwave ridging meanwhile advances from the western Plains in the wake of the upper trof, moving into the central states on Sunday. Lows tonight will range from the lower 50s inland to near 60 at the coast.
Mid level ridge stretches across the southern CONUS emanating from the mid level height center across western Texas.
A lee trof will dig southward from the foothills of the Central Rockies ahead of a slowly approaching cold front that is currently located across central Nebraska. H850 temps will be one to two degrees warmer than yesterday resulting in highs in the upper 80s across most of the FA with a few low 90s possible across our northeastern zones. Ridging across NRN MX and the SRN CONUS will flatten through the weekend.
Powerful Polar jet stream arching well to our north around a strong mid-level anticyclone/high pressure centered over New Mexico at the present time will propagate eastward during the first half of the upcoming week.
226 PM EDT Sat Oct 29 2016 Aloft - Broad flat ridging resided across the Gulf coastal region. Surface - High pressure on the VA/NC coast ridged across the Deep South to the southern plains. The upper ridge nudges eastward while sagging slightly to the south in response to a short wave trough moving across the Great Lakes tonight and over the Mid-Atlantic states Sun. which will be dominated by the ridge to the north and the frontal boundary to the south. about 3 to 5 degrees for the lows and 2 to 4 degrees for the highs.
A weak cold front will move south across terminal sites, with KGUY experiencing a northerly winds around 10 kts at 29/17Z, KDHT at 30/00Z and KAMA at 30/06Z. Southwest winds this morning will be of stronger speeds than the those of the afternoon, including those following a weak cold front which will move into the northwest one-third of the forecast area today. Light north winds Sunday morning will trend to east and southeast by day's end, with Sunday highs a bit cooler, but still above climo.
Cooler with Night and Morning Low Clouds Possible on the Plains. Behind it, a surge of cooler air will settle south across the plains. On Sunday, temperatures will be a little cooler over the area as the result of the disturbance that moved through today. Southwest breezes will begin to increase over the high country in the afternoon ahead of an approaching disturbance. Winds across the lower elevations should generally remain under 20 mph throughout the day.
Our winds remain below 15 mph in most locations, despite temperatures in the lower to upper 70s. Tonight, the cold front which has temporarily mixed back to northern Iowa will advance southward as a weak wave of low pressure slides along the front. I have gone a degree or two cooler than guidance for highs Sunday under the clouds and northeast winds. This is expected to hold us in the mid 50s north to the lower 60s south. By afternoon Sunday, high pressure ridging will move into western Iowa, but the northeast flow will continue in eastern Iowa and Illinois. After a cold front moves through the area, high temps will be only a few degrees above average.
1210 PM CDT Sat Oct 29 2016 A cold front located across northern NE will continue to slowly move southward through the region today, which will provide a fairly tight temperature gradient across the forecast area. The upper wave will continue to move east southeast into the mid MS valley tonight while high pressure continues to build into the region. Highs Sunday will be in the lower 60s, which is still a couple of degrees above normal.
Further offshore and across the remainder of the Gulf, a modest pressure gradient continues between the high and broad low pressure across the NW Caribbean. Fairly stagnate weather pattern will continue over the area as high pressure at the surface and aloft will dominate our region with little to no chance for precipitation.
As an upper level trough moves onto the west coast from off the Pacific and through Nevada and Idaho, southwest winds and mid to upper level moisture will increase ahead of it Sunday afternoon and evening. H7 winds increase to about 30 kts on average for Sunday afternoon with upwards of 50 to 60 kts by Sunday evening and night just ahead of trough passage. That moisture then works down to the low levels after midnight Sunday night with showers then developing across mainly northeast Utah and northwest Colorado as the trough moves through Wyoming and the northern Rockies, clipping our north.
/issued 419 AM CDT Sat Oct 29 2016/ (Today and Tonight) Upper level high pressure will continue to bring warmer temperatures to the area through today.
Persistence continues to reign supreme with regard to the forecast across the Lower Mississippi Valley. The stubborn ridge of high pressure aloft and at the surface shows little signs or impetus to move from overhead, despite a weak short wave drifting west to east to our north through the short term period. /BB/ An upper-level ridge will continue to dominate the weather pattern though the middle of the week ahead. The core of the ridge will shift from over Texas this weekend to over the southeast U.
Another warm night is expected across the region ahead of our next weak cold frontal boundary due into the region by tomorrow. With the frontal boundary and parent trough, clouds will increase across the region. No rain is expected, however, there should be a tight temperatures gradient along the Interstate 44 corridor with the coolest temperatures expected to be in over central Missouri where dense cloudiness will keep those locations about 10 to 15 degrees cooler than today. Although some locations will be cooler, the coolest conditions will remain northeast of our region, similar to systems past.
332 PM EDT Sat Oct 29 2016 The latest surface map features high pressure across the southeastern CONUS. A quick-moving low pressure system is currently moving across western Quebec, with a cold front aligned southwest into the Great Lakes and Midwest. Aloft, higher heights continue to expand across the lower third of the CONUS, thanks to the upper level ridge centered across northern Mexico, with flatter and progressive flow across the majority of the rest of the CONUS. Expect lows to range from the low to mid 50s in the valleys, to around 60 on the ridges. Clouds will be on the increase into Sunday as a cold front approaches from the northwest. A few showers/sprinkles will accompany the cold front as it drops southeast across our region late tomorrow afternoon into Sunday night.
east of the cascades winds are expected to reach advisory level with even stronger winds on the ridge tops. A trough cycles through behind the front Sunday afternoon, bringing a round of increased showers, and with cooler air moving in aloft bringing increased instability, isolated thunderstorms are also possible.
235 PM MST SAT OCT 29 2016 Dry weather with mostly clear skies will continue this weekend, with desert temperatures continuing in the lower 90 degree range.
The Ozarks remain underneath an upper level ridge and between high pressure to the east and low pressure in the plains. Afternoon temperatures as a result will climb into the lower 80s today which is in excess of 15 degrees above the normal highs for this time of year. A dry cold front will move through the area early Sunday but provide only a brief wind shift from the north.
Upper ridging to start the period will begin flattening out and allow southwest flow aloft to return.
145 PM EDT Sat Oct 29 2016 Return southwesterly flow between departing high pressure to the east and a slowly moving cold front to the northwest will bring much above normal temperatures to the region today. The cold front will push south through the area Sunday into Sunday night.
However, even the moisture in the north is somewhat marginal therefore any shower activity into tonight will be spotty and light as the cooler airmass deepens across the state.
147 PM EDT Sat Oct 29 2016 A cold front will cross the area tonight.
628 PM EDT Sat Oct 29 2016 A cold front will increase rain chances for tonight and Sunday. High pressure will then return dry and warm conditions through midweek. A weak cold front will sink into the area from the north late this evening with an increase in clouds and eventually rain chances north of I-80. The passing cold front will lead to a strong gradient in high temperatures north to south tomorrow, but highs will generally above-average.
351 PM EDT Sat Oct 29 2016 Eastward moving low pressure over southwest Quebec will take a cold front across northern OH/nw PA late tonight.
421 PM EDT Sat Oct 29 2016 High pressure settles off the southeast coast through Sunday.
253 PM EDT Sat Oct 29 2016 High pressure will remain across the area through the weekend.
Ahead of this cold front the tight pressure gradient has caused increased wind speeds. Occasional wind gusts will reach the surface this morning especially the higher locations. The 850 temperatures are forecasted to be fairly similar to yesterday so expect highs in the lower to mid 80s once again. Winds will shift to the north behind the front brining cooler air to the area therefore lows tonight will range from the mid 40s to the mid 50s. Sunday could end up being the coolest day in the forecast, as cooler high pressure drops into the upper midwest and into northeast Kansas through the day, keeping highs in the 60s.
240 PM EDT Sat Oct 29 2016 An unseasonably strong 500 mb ridge over the southern United States will keep our region on the warm side of normal most of the coming week.
High pressure over the Southeastern States will keep dry weather across Central Indiana tonight as it drifts farther east. A cold front over the Upper Midwest will sag southward across Indiana on Sunday.
Deep boundary layer moisture and decreasing winds late tonight will promote fog development over the high plains.
251 PM EDT Sat Oct 29 2016 High pressure settles off the southeast coast through Sunday.
404 PM EDT Sat Oct 29 2016 An unseasonably strong 500 mb ridge over the southern United States will keep our region on the warm side of normal most of the coming week.
Even with high clouds present, persistent southerly flow today has warmed temperatures into the lower 80s. Clouds are expected to hold on until mid-day tomorrow with skies mostly sunny by the afternoon as high pressure noses into northeast Kansas. Went a few degrees cooler for Sunday due to the front being more south than model guidance was suggesting. Models are in agreement with a upper trough moving into the west coast Sunday night with a ridge building over the Central Plains.
329 PM CDT Sat Oct 29 2016 Surface cold front continues to make progress southward through the FA this afternoon. A much cooler day is expected for Sunday, but still above normal for late October.
Overall though, should see dry weather under the high. Will be a cooler day, with highs back around normal for late October.
546 PM CDT Sat Oct 29 2016 A cold front near GUY will continue to push south this evening and it should push through AMA by midnight. /Issued 353 PM CDT Sat Oct 29 2016/ A cold front will move south through the region to start the forecast period later this evening into the morning hours on Sunday.
As Pacific low pressure moves inland and across the western states on Sunday, Arizona will see an increase in southwesterly flow. The highest increase in winds will be over northwestern Arizona with gusts up to 45 mph, where a wind advisory has been issued.
227 PM CDT Sat Oct 29 2016 A cold front moving through tonight will bring a temporary reprieve from the 20+ degree above normal temperatures.
The low that went through the area yesterday has left us in predominantly northerly flow this morning, and those very warm 850mb temps will gradually cool to more normal levels for this time of year. This wave will be pretty progressive, moving through by tonight with high pressure right on its heels to build in overnight.
The greater coverage has favored the Atlantic waters south of the Lower and Middle Keys, but the threat to the island chain and nearshore Gulf and Bay waters has also remained well above normal.
605 PM EDT Sat Oct 29 2016 Eastward moving low pressure over southwest Quebec will take a cold front across northern OH/nw PA late tonight.
The highest daytime winds willbe up around GLH/GWO where surface speeds up to 15 mph out of thesouthwest cannot be ruled out at times. Morning 12Z JAN sounding reveals an even drier air mass than was the case yesterday with low level temperatures through 4 or 5 KFT perhaps a degree C warmer than was the case in comparison to the 12Z sounding yesterday.
Predominantly VFR or MVFR CIGS and VFR visibility expected at the TAF sites through 18Z/Sun as a mid- to upper-level high pressure ridge resides over the area and low to mid-level moisture streams through the ridge.
319 PM CDT Sat Oct 29 2016 Closed low over the eastern Pacific with strong deepening Hudson Bay low and western Ridge between the two. A dirty ridge is shown to build across the upper Missouri Basin and across the eastern high plains overnight. Southerly flow and strong warm air advection Sunday night will lift a warm front across the area with lows quite mild in the upper 40s to around 50.
Thus, will go on the low side or below guidance on lows tonight, but only a degree or so. Seas Sunday are forecast a bit lower, but sometimes the wave watch will be on the low end of actual waves.
Expect this to gradually taper and move towards the south as better lift focuses over that area and ridging amplifies to the west. Overcast skies and cooler conditions will highlight the short term forecast. Notably cooler conditions are expected with highs in the 40s.
300 PM EDT Sat Oct 29 2016 High pressure will build across the area through Sunday.
327 PM CDT Sat Oct 29 2016 (Tonight and Sunday) Going with a dry forecast the next 24 hours as upper level high pressure ridge continues to bring very warm and dry weather.

A ridge of high pressure will continue north of the area while an old frontal boundary resides to the south. High pressure north of the waters and an old front to the south maintain northeasterly and at times robust winds today.
203 PM CDT Sat Oct 29 2016 Another cool and dry night across the TN valley as a strong area of high pressure cover the region. Morning lows will mainly drop into the lower 50s under clear skies.
353 PM CDT Sat Oct 29 2016 A cold front will move south through the region to start the forecast period later this evening into the morning hours on Sunday.
Upper low seen on w/v imagery near Tampico will make its way westward into Mexico over the next couple days. As this occurs, a ridge will expand eastward over the top and eventually settle over the eastern Gulf and southeastern states for most of the work week. At the surface, southeast Texas will remain situated on the western periphery of a ridge anchored across the northern Gulf and southeast. The higher than normal tides combined with waves has also led to strong rip currents being noted by the beach patrol.
313 PM CDT SAT OCT 29 2016 With high pressure ridge to the southeast and another storm system developing in the Plains, Central Illinois is dominated by warm and breezy conditions this afternoon. However, a cold front to the northwest will slowly drift into the region later tonight. bringing cooler temps with it. We will only see a glancing blow of the cool high pressure, allowing low temps Sunday night to remain above normal.
The ridge of high pressure did allow for some areas to receive plenty of sun. The ridge will shift to the east later this evening allowing for a plume of moisture to cause widespread precipitation from Idaho/Clearwater counties up into northwest Montana.
316 PM EDT Sat Oct 29 2016 Low pressure over the northern Great Lakes will track across Quebec tonight. This low will drag a trailing cold front across the region Sunday and move to the south of our area by Sunday evening while another weak low travels along it.
125 PM EDT Sat Oct 29 2016 High pressure will remain across the area through the weekend.
136 PM EDT Sat Oct 29 2016 Aviation/Hydro A weak cold front will push southward through Michigan today and tonight resulting in some showers and perhaps even a few thunderstorms.
253 PM EDT Sat Oct 29 2016 A cold front will move across the area tonight following by a good chance for rain from far southern Lower Michigan into northwest Ohio early Sunday. Rain should end by Sunday evening as high pressure builds into the area. Unseasonably warm weather was over the area and ahead of a cold front this afternoon with temperatures around 70 to the upper 70s. A cold front extended into far northwest Illinois across Lower Michigan.
Records are 85 for PAH and 83 for EVV and our high temp forecast is right in that ballparkm, Esp given start day temps some 15-20F warmer than yesterday's. A weak wave/ripple passage does lay a front down across the Ohio river valley Sunday, but the modeled strength of the Upper ridge is such to blunt any effects from it here, this far south/west, save maybe a shave of a degree or two off Saturday highs with a few clouds, but still plenty of sunshine.
123 PM EDT Sat Oct 29 2016 High pressure settles off the southeast coast through Sunday.
408 PM EDT Sat Oct 29 2016 Dry tonight with high pressure holding on, and above normal temperatures again Sunday.
and Sunday A cold front will continue sinking south early this morning. High pressure will build in across the western Great Lakes on Sunday, bringing dry weather and cooler temperatures behind the departing low pressure system. Although temperatures will be a good 5 to 10 degrees cooler on Sunday, they will still be right around normal for this time of year.
Upper ridge centered over the lower plains states will continue build east over the lower MS river valley and central gulf states. Day and nighttime temps will continue to be well above seasonal averages with highs ranging from the mid to upper 80s inland and the lower to middle 80s near the coast. Lows tonight will range from the lower to middle 50s inland and the upper 50s to lower 60s along the immediate coast.
1208 PM CDT Sat Oct 29 2016 Abnormally warm conditions will continue for most of the period with a brief interruption on Sunday as a dry but shallow cold front settles south on Sunday. Inspection of model soundings indicate h8 temperatures could be several degrees warmer than yesterday. A very warm start will also aid in reaching temperatures a degree or two warmer than yesterday.
312 PM EDT Sat Oct 29 2016 High pressure will remain across the area through the weekend.
Elongated area of high pressure across the Southeast U. Highs tomorrow will once again reach the low-mid 80s. Moisture is shunted southward as high pressure builds down the eastern seaboard. Max temps are forecast to remain slightly above normal in the low to mid 80s while Min temps remain quite mild near the coast due to persistent onshore flow. Anticyclone aloft slowly builds while retrograding southwest into the Gulf as trough drops southeast from the Great Lakes toward the mid Atlantic coast and deepens. High pressure north of the area shifts slowly southward into tomorrow with E/NE winds decreasing slightly from north to south over the area. Then another reinforcing high pressure will build down the eastern seaboard mid week resulting in a tightening of the pressure gradient and seas building 5-6 ft nearshore and 7 ft offshore.
Gradient slacks off tonight and then the next cold front begins moving in overnight. The cooler NAM temperatures look better at this point. JPK Cooler high temperatures can be expected on Sunday as a cold front drops southward through the forecast area. Low level cold air advection along with post frontal low level clouds will lead to cooler high temperatures, particularly across northeast MO and west central IL, albeit still above normal for late October.
A large upper ridge will remain centered over the Southeastern states, where its persistence has led to extreme drought in places like north Georgia and south Tennessee. The front will come through dry, but a zone of scattered to broken cumulus clouds will likely accompany the higher dew points pooling near the front.
700 PM EDT Sat Oct 29 2016 High pressure will prevail through the weekend.
By Sunday night, the inverted trough aloft will have rounded the SW flank of the upper ridge and begin trekking north through northern Mexico.
338 PM EDT Sat Oct 29 2016 High pressure will prevail through the weekend.
1203 PM CDT Sat Oct 29 2016 A cold front will sag across the local area this afternoon bringing ample mid/high level cloud cover and generally cooler temperatures to at least the Nebraska portion of the forecast area today. where compression ahead of the front should allow temperatures to climb into the lower to middle 80s. had trouble forecasting RH values below 30 percent thanks to the accompanying cooler forecast temps. steady northerly winds will promote mixing of the lower layers of the atmosphere through much of the night. a significantly cooler airmass will advect into the central plains. cooler. Temperatures will be cooler than Saturday.
141 PM EDT Sat Oct 29 2016 Mild temperatures will occur today as high pressure slides to the south of the area. A cold front will bring a chance of showers to the northern mountains late in the day and tonight, and to all of central PA on Sunday.
Yet another unseasonably warm afternoon for SW KS, with SWly downslope winds and prefrontal thermal ridge ahead of advancing cold front. Cooler with northern extent as winds veer northerly later this afternoon. Gusty N/NE winds of 15-25 mph will prevail for several hours this evening, with cool advection following the cold frontal passage. Lows Sunday morning will range from near 40 west to the lower 50s far SE, still well above average for late October. Various models do hint at a brief period of stratus behind the cold front late tonight and Sunday morning.
255 PM EDT Sat Oct 29 2016 High pressure will continue to drift south from the Carolinas through Sunday. A cold front will cross the central Mid-Atlantic Sunday evening.
Forcing: Sfc/upper level low lifts northeast across the region and into southern Canada Tuesday afternoon. The low slides its sfc cold front across the local forecast area overnight/tue morning. Meanwhile a mid layer of clouds is expected to ride over the low cigs. Ptype looks like drizzle/freezing drizzle initially, changing over to snow for a few hours around the front, and then possible a wintery mix post. The departing upper level low/trough from Tue setups a northwesterly fetch for the Upper Mississippi River Valley. A cold front will move east across the area tonight.
diffuse low pressure which is currently digging into the western Dakotas should coalesce into a strengthening low pressure center in northeast SD by early afternoon. Models are generally consistent in placing the Low center near ABR around 21z. and expect that warmer temps there will slow and sig snowfall accumulations til the late afternoon and evening. Blowing snow could develop during the early morning period in eastern ND as the low pressure center pivots into northwest MN. The Low pressure center is expected to track across northern MN through Tuesday forenoon and into northwest Ontario during the afternoon.
Widespread showers and isolated thunderstorms are occuring out ahead of this system as the low tracks Northeast towards the area. This low will track from southwest Louisiana up along the Natchez Trace Corridor this evening through the overnight hours. As the low tracks north this evening into the overnight hours, there will be a window of opportunity for severe mainly south of the natchez trace corridor. The low will move northeast of the area Tuesday morning with a few light showers possible in the northeast, ending by lunchtime.
247 PM CST Mon Dec 5 2016 Upper low currently across south central Texas will continue lifting northeast and weaken as it moves through southern Arkansas overnight. Initial push of cooler air will move into the area overnight.
