This will continue to create well above seasonal average temperatures in the low/mid 80s for the CWA with some near record highs possible in some locations. The mid level impulse exits the Plains Sunday night with a building ridge of high pressure over the Central U.
227 AM EDT Sat Oct 29 2016 Much warmer today with increasing clouds. A cold front will bring rain chances tonight and Sunday. Cirrus a bit thicker on eastern edge of building upper level ridge. Low level southwest flow will push a warmer air mass over the CWA today.
Isolated showers will once again be possible from the late morning through mid aftn across mainly the eastern half of South TX due to increased Gulf moisture from an approaching upper low.
403 AM MDT Sat Oct 29 2016 Weak upper trough axis will pass this morning. Could be some snow mixed in at pass levels, but any accumulation will be limited to the highest ridges. At the surface a weak cold front will pass this morning with cooler air moving in on northwest winds, turning N-NE this afternoon. Lows will be a bit cooler than the past several nights, though wind over the higher mountains and east slopes will keep readings milder in those areas. On Sunday, an upper ridge moves eastward out of Colorado with southwesterly flow aloft on the increase.
The pattern of low level warm advection, subsidence under a midlevel ridge, and full sun will continue to push temperatures well above normal today, into the upper 70s to mid 80s.
408 AM EDT Sat Oct 29 2016 Much warmer today with increasing clouds. A cold front will bring rain chances tonight and Sunday. Low level southwest flow will push a warmer air mass over the CWA today. Upper flow will become zonal, hindering the initial approach of a weak cold front from the north.
305 AM CDT Sat Oct 29 2016 A large broad upper level ridge of high pressure covering the southern United States will continue to directly influence the weather conditions over the Mid South for the next several days. High temperatures will range from the lower 80s north to upper 80s south.

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.
High pressure centered along the Mid-Atlc seaboard this morning is forecast to sink slowly Swd while stretching from E-W into Sunday.
Another trough of low pressure will lift northward across the area today bringing a return of showers over the area.
119 AM EDT Sat Oct 29 2016 Much warmer today with increasing clouds. A cold front will bring rain chances tonight and Sunday. Cirrus a bit thicker on eastern edge of building upper level ridge. Low level southwest flow will push a warmer air mass over the CWA today.
555 AM CDT Sat Oct 29 2016 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.
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.
131 AM EDT Sat Oct 29 2016 High pressure sliding east equals a warm up for the area this weekend.
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. Deep-layer ridge will dominate the pattern over the Deep South through the weekend, with the main band of westerlies confined well to the north.
Weak high pressure will temporarily move over the region today before another system moves in tonight and Sunday. This system will bring another round of precipitation to the area and will produce significant snow over the higher elevations of the Sierra Nevada.
1207 AM CDT Sat Oct 29 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. A trough will move through later Saturday with a batch of cold air advection to cool things down relatively speaking for Sunday, but temperatures are still expected to be above seasonal normal which is in the mid 60s. There is a trough to move across the central U.
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. Sunday, high pressure will build over the area but with low level moisture below a strengthening inversion, mostly cloudy skies will prevail keeping highs in the mid to upper 40s.
202 AM EDT Sat Oct 29 2016 High pressure will build across the area through the weekend with above normal temperatures.
313 AM 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.
A secondary cold front was draped across srn Ontario and was working with deeper moisture, resulting in showers and even a few thunderstorms. The low pressure and warm front will blow through over the next handful of hours with the light rain/drizzle gradually ending. Could still be some spits of rain around with the cold front arriving this morning, but it's primarily just going to be a cloudy day.
335 AM EDT Sat Oct 29 2016 High pressure will remain across the area through the weekend.
401 AM 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.
SHORT TERM (Today through Sunday): A few morning offshore showers have been struggling to progress inland as dry air and the capping affect of the H5 ridge continues to dominate the weather. Models still indicate a slow moistening up of the low to mid levels as an inverted trough moves across the far the Southern Texas coast.
640 AM EDT Sat Oct 29 2016 Low pressure will exit the Gulf of Maine this morning followed briefly by a weak ridge of high pressure. Low pressure over the northern Great Lakes will track across Ontario and Quebec today and tonight. This low will drag a warm front north into the area today followed by a trailing cold front tonight. The cold front will sink slowly to the south of our area on Sunday while another weak low travels along it.
146 AM EDT Sat Oct 29 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.
Warm and dry weather is expected to start the weekend as High pressure east of Indiana allows pulls warm southerly breezes into the state. A quick but weak cold front is expected to sag across Indiana from the Upper midwest on Sunday. This will result in an increase in cloud cover along with cooler.
132 AM EDT Sat Oct 29 2016 High pressure will control our weather pattern through at least Sunday with dry and mild conditions.
/issued 935 PM CDT Fri Oct 28 2016/ 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.
Ridging in from the northeast should keep most of the region dry today but isolated to widely scattered showers and possibly a thunderstorm or two will be possible mainly southwest of a Brenham to Galveston line.
332 AM EDT Sat Oct 29 2016 A cold front will cross the area tonight.
350 AM CDT Sat Oct 29 2016 A ridge of high pressure will continue to dominate over the region this weekend, yielding continued well above normal temperatures and dry conditions. Lows overnight tonight will generally be in the 50s, with some 40s possible in higher terrain, and lows in the lower 60s through portions of the Rio Grande Valley and Western Low Rolling Plains. Sunday will be similar to today, though a few spots could be a degree or two warmer Sunday afternoon.
315 AM CDT Sat Oct 29 2016 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.
230 AM MST SAT OCT 29 2016 Dry weather with mostly clear skies will return this weekend, with desert temperatures continuing in the lower 90 degree range.
Decreasing clouds over most of the region today and tonight except for far western Humboldt County where next low pressure system is approaching the coast.
437 AM 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.
High pressure will remain positioned over the southeast through the short term, stamping out all but the slightest cu field through the weekend.
Medium Gusty southwest winds will continue to diminish as weak surface cold front over central WI moves south this morning. Temperatures will drop a bit this morning most areas as cooler air settles in, but mainly high clouds this morning should allow some recovery. Increasing north to northeast winds will retard any afternoon warmup closer to Lake MI with these cooler temperatures spreading inland during the afternoon. This could end up a little warmer if clouds stick around through the night.
624 AM EDT THU JUN 16 2016 The weather will be fair and seasonable through the weekend as high pressure dominates. The cloud cover will be the result of a low pressure system tracking southeast from the Ohio Valley into the Middle Atlantic region. Meanwhile high pressure will dominate the weather across the northern half of the area. Fair and dry weather is expected from tonight into the upcoming weekend as a sprawling ridge of high pressure settles across the northeast.
Current Situation and Analysis -- An upper-level composite analysis early this morning reveals a deep layer mean anticyclone centered just north of Hispaniola.
358 AM CDT THU JUN 16 2016 UA ridging continues to dominate across the central CONUS and thus also the Four-State region early this morning, which has aided in keeping precipitation at bay. It is the Central Plains that is experiencing showers and thunderstorms as noted by an MCS across SE KS and SW MO, that was sparked by a weakness rounding the UA ridge. Computer models show the MCS waning in the coming hours and remaining to our North, though this embedded weakness is anticipated to translate South across the region late this week/early this weekend, whilst the center of the UA ridge retrogrades to across the Desert SW.

A few isolated thunderstorms across northeast Arkansas should diminish tonight and skies will clear underneath a ridge of high pressure building into the area. Dew Points in the mid 70s with air temperatures in the lower 90s have produced heat indices this afternoon over 100 degrees just about everywhere across the state and over 105 over the majority of it. Upper level ridging will build across the state through Thursday with the warmest day of the week expected. Models continue to show a backdoor cold front coming through on Friday to knock the ridge to the west a little bit and bring in slightly cooler air although dew points will remain up.
330 AM CDT THU JUN 16 2016 (Today and Tonight) An upper level high, centered over northern Mexico, will remain in place today and tonight while a ridge builds north across the eastern Plains and western portions of the Midwest. Surface dewpoints are expected to drop into the lower 60s this afternoon across the western parts of our area, and into the mid to upper 60s across our eastern counties. With south winds, temperatures will be warm again tonight, with overnight lows in the lower to mid 70s.
247 AM PDT THU JUN 16 2016 Low pressure will bring gusty winds and cool temperatures into Friday.
353 AM EDT THU JUN 16 2016 A strengthening area of high pressure should lead to an extended stretch of warm temperatures, comfortable humidity levels and dry conditions today through the weekend.
105 AM EDT THU JUN 16 2016 Strengthening high pressure across western New York and Ontario will build eastward bringing a prolonged stretch of dry weather to the North Country through the upcoming weekend. Warmer temperatures and relatively low humidity levels are expected.
Southwesterly winds associated with troughing over the Pacific NW will weaken Thursday and Friday as high pressure begins building in from the southeast.
Cyclonic flow around the low will bring low clouds through the area today into this evening, before moving out of the area later tonight. 925 mb temperature fields from short term models support highs in the lower to middle 70s.
650 AM EDT THU JUN 16 2016 Low pressure will drop southeast across the area today. a cold front will accompany the low as it moves through. High pressure will follow. Expect showers and thunderstorms to redevelop in the late morning and afternoon across the area ahead of the low. This evening and overnight the low will continue southeast as high pressure builds from the northwest.
303 AM EDT THU JUN 16 2016 Low pressure over Newfoundland will continue to move slowly east through Friday. A ridge of high pressure will gradually build into the region through the weekend with much warmer weather.
An upper low could bring a small chance for a thunderstorm in the northeast Thursday but will also serve to usher in cooler drier air for Friday.
330 AM CDT THU JUN 16 2016 With the cooi front moving off to the east and south, surface ridging will build into the area for the day. Temperatures will be slightly cooler than yesterday, but still expecting warm temps in the middle 80s in the north to lower 90s in the southwest and southeast IL. Fair weather expected tonight as NE winds continue to filter in drier/less humid air into Friday as weak high pressure 1019 mb settles into the Great Lakes on Friday. Lows tonight mostly in the lower 60s as northeast winds diminish to 5-10 mph after sunset. Strong upper level ridge already building northward into the Midwest on Friday, and will bring dry weather to the area through this Father's Day weekend.
305 AM MST THU JUN 16 2016 The large Pacific low pressure system along the west coast that had kept afternoon temperatures below normal for the past six days will weaken today.
310 AM EDT THU JUN 16 2016 Low pressure will drop southeast across the area today. a cold front will accompany the low as it moves through. High pressure will follow. Expect showers and thunderstorms to redevelop in the late morning and afternoon across the area ahead of the low. This evening and overnight the low will continue southeast as high pressure builds from the northwest.
The upper low was drifting over northwest Wisconsin with showers still dotting the landscape. Widespread showers will continue across much of the Northland while the affects of the upper low linger. High pressure ridging will build behind the departing low for Thursday resulting in increased sunshine and drier conditions for the Northland. Northeast winds over western Lake Superior may work to keep clouds and cooler temperatures in place for inland locations along the shore for much of the day. High pressure will build into the Northland providing dry and quiet conditions for much of Friday. Will see a ridge axis extend across the Upper Midwest into Hudson Bay on Friday.
335 AM EDT THU JUN 16 2016 Crossing low pressure will bring showers and thunderstorms to the Upper Ohio Valley Region today. A better chance for precip will come today and this evening as deepening low pressure is still forecast to dig southeastward across the Great Lakes, with passage across the Upper Ohio valley region expected by late evening. Limitations included a weakening wind field and relatively warm mid levels, but these are expected to be offset as lift improves with the low advancing toward a very moist, and diurnally- destabilizing airmass. Dry mid level air is also progged to advect into the advancing low, enhancing downdraft CAPE and thus wind gust and cold pool potential with MCS possibility along the trailing cold front. Building high pressure will improve conditions rapidly behind the exiting low.
Thunderstorms are possible today across much of the area since low level moisture has moved westward toward southeast New Mexico and the higher terrain. Temperatures this afternoon are again expected to be hot but may be a degree or two cooler than yesterday due to an increase in moisture. This strengthening of the ridge will limit thunderstorm development to the Davis Mountains and higher terrain for Thursday afternoon. The ridge will be slightly stronger over the area on Friday allowing for temperatures to warm up even more and further decrease precipitation chances.
SHORT TERM (Now through Friday): Water vapor imagery this morning shows the center of mid-level ridging nearly overhead. The 500mb ridge over Texas will slowly retrograde towards the north central Mexico and the Texas Big Bend Region through the forecast period. High temperatures today and Friday will range from the lower 90s near the coast to the mid and upper 90s across the mid valley to above the century mark across the upper Valley and the West. The main forecast issue through the short term will be the high heat indices. High pressure over the Gulf of Mexico will support moderate south-southeast winds today and Friday.
138 AM EDT THU JUN 16 2016 Weak low pressure passes us to our west and south this morning reaching the Carolina Coast by Friday. High pressure otherwise builds in from the north for the weekend and into the start of the new week. A cold front approaches for the middle of the new week. Weak surface ridging from the north then keeps us dry Thursday night Upper trough along the East Coast on Friday flattens out and moves offshore as closed H5 high strengthens over the SW U. will strengthen, and upper level ridging ahead of that high will build into the East Coast.
Temperatures have cooled into the lower 70s behind outflow providing a brief break from the oppressive heat which will likely continue for the next couple of days. Heat index values around 115 degrees are again expected across northeast Oklahoma this afternoon as upper ridge continues to build into the region.
A weak ridge of high pressure will temporarily bring some clear skies over the region. Some lower valley locations in Northwest Montana may dip down to the freezing mark for an hour or two.
So for a good portion of south central Alabama it has been a cooler day, while northern Alabama has been cooler than the past few days but still muggy. So at are warmest time the dew points will be the lowest and stay just below heat advisory criteria for Thursday. Friday will likely be a few degrees warmer and dew points a touch higher as well. Still looking dry for the weekend and slightly cooler.
As the upper level trough driving the surface system shifts southeast toward the Appalachians, slightly deeper moisture and lift will be positioned closer to the northern part of the forecast area; including Southwest Virginia and Northeast Tennessee. Lows will be similar to the past few days ranging from the mid 60s north to the lower 70s south.
/issued 823 PM EDT WED JUN 15 2016/ Similar to yesterday upper level warm dry air (-5C at 500MB) and subsidence combined with the fast inland progression of the west coast sea breeze within the low and mid level southwest to west wind flow lead to limited convective development and coverage across the forecast area during the afternoon hours with only a few showers and storms observed.
Following this, mainly clear skies will prevail for the rest of the work week, though some clouds wrapping around the upper low associated with the cold front may linger along the I-75 corridor through the day Friday. These winds will help return drier and somewhat cooler air into the area. While highs today will still reach into the low to mid 90s for central Kentucky, parts of southern Indiana should stay in the 80s as the front moves through early enough to cutoff the daytime heating. By Friday, as the cooler air continues to filter southward, highs will be confined to the lower to mid 80s - right in line with climatological norms for the date. Morning lows Friday will be at or just slightly above average, from the lower 60s north to around 70 along the Tennessee border.
