High temperatures today reached the upper 90s across the northwestern quadrant of the CWA, while highs reached the low to mid 90s elsewhere. The high temperature of 93 degrees at Houston Hobby Airport tied the previous record that was set in 2013 and 2006. High temperatures in the mid to upper 90s can be expected over the northwestern quadrant of the CWA, and in the low to mid 90s elsewhere.
There will be a couple of strong back door cold fronts but without a lot of moisture behind them.
The cold front continues to move south through the area. /issued 303 PM CDT Sat Oct 5 2019/ A few showers and storms have developed over the past hour near a cold front in central and north central Oklahoma. Overnight into Sunday morning, additional showers and storms should develop as 85H winds increase ahead of a trough to our northwest. Cooler and drier air will settle across most of the state Sunday into Sunday night as the aforementioned trough moves east of the area.
Surface observations and radar this evening show a surge of Gulf moisture with dewpoints in the low to mid 60s continues spreading northwestward through the area, and currently stretches from Lawrenceburg to Celina.
/issued 257 PM CDT Sat Oct 5 2019/ Cold front is currently located across the Southern Panhandle and will continue to gradually move to the south this evening. This will keep temperatures a bit cooler tomorrow compared to today.
Thus, will leave the low PoPs (20% or less) in the forecast overnight.
A frontal system may bring showers and isolated thunderstorms to portions of the area tonight into tomorrow night, before high pressure moves back into the area and leaves the early to middle portions of the work week dry.
853 PM EDT Sat Oct 5 2019 High pressure ridging into the area from the north will hold widespread clouds and much cooler temperatures over the area through tonight.

An upper trof and associated jet streak will move eastward across the northern Plains/Upper Midwest today.
A cold front will bring widespread rain late Sunday and Monday. Still expect some showers to develop towards the eastern portions of the CWA as persistent, moist easterly flow into the ridges aids precipitation development. By Sunday Morning, a low pressure system is expected to be positioned in Ontario, with a cold front stretching down southward through Canada and through the Ohio Valley. The cold front and associated rainband is forecasted to arrive late Sunday night. No mentionable precipitation is expected until late week as warmth and moisture increases ahead of an approaching low pressure system.
ridge building influences our weather as major large scale pattern amplification occurs through the week. A large and deep trough develops over the western U.
1108 PM MDT Sat Oct 5 2019 Current surface analysis shows low pressure over northwest MN, with front well east of the area. Upper level analysis shows trough over the eastern Dakotas, with west-northwest flow extending back to the Pacific NW. Skies are mostly sunny to partly cloudy with temps mostly in the 50s and lower 60s, some 40s over the higher Black Hills. Cool and breezy weather will persist through the rest of the weekend as pressure gradient remains fairly tight between low pressure to the northeast of the region and high pressure slowly moving across the northern Rockies.
/Issued 859 PM CDT Sat Oct 5 2019/ Cold front stretching from swrn MO into central OK and swrn OK at 02z will continue to move slowly southward tonight into sern OK and west central AR by daybreak Sunday.
1152 PM CDT Sat Oct 5 2019 The cold front is pushing through the area currently and is expected to be through the entire forecast area later this afternoon or early this evening. Otherwise, just cloud cover may spread northward with cool autumn-like temperatures in the low to mid 60s expected. Models are in general agreement moving a strong storm system across the northern Plains and surging a strong cold front through the area.
Weak ridging is over the region today. At the surface, weak high pressure is over the region today. A cold front is well to the north today near KY/TN. Highs will be slightly cooler today in the upper 80s and near 90 due to increasing cloud cover.
Despite the high pressure in place, a few tstms will be possible areawide during Sunday aftn. In addition, shwrs/tstms associated with an approaching cold front will begin to move into the area towards the end of the pd, but should avoid terminals until beyond the pd. However, cold front draped across sern OK into nwrn AR will continue to very slowly drift swd tonight, and may allow for a stray storm or two to make it in to McCurtain Co overnight. /Tonight through Sunday Night/ Light and variable winds along with clear skies to continue overnight as surface and weak-upper level ridging prevail across the ArkLaTex. Afternoon high temperatures across the region to climb into the lower 90s. Much cooler temperatures expected on Monday morning with lows in the 60s.
High pressure aloft will build in tonight into Sunday for dry weather.
A cold front will move through during the morning hours today with chances for rain and a few thunderstorms continuing through tonight.
Surface winds expected to shift to northeast before 18z with arrival of secondary cold front. Otherwise, another reinforcing cold front is in store with a secondary push of cooler air coming into the region midday Sunday. A secondary surge of cooler air from the north is anticipated AFT 06/15Z, which will raise northerly winds to around the 15 to 25 kt range to close out the TAF period.

High temperatures today reached the upper 90s across the northwestern quadrant of the CWA, while highs reached the low to mid 90s elsewhere. The high temperature of 93 degrees at Houston Hobby Airport tied the previous record that was set in 2013 and 2006. High temperatures in the mid to upper 90s can be expected over the northwestern quadrant of the CWA, and in the low to mid 90s elsewhere.
A secondary trough axis will cross our region tonight into Sunday morning, shifting flow from the northwest again as the trough deepens over the Central Plains. Another clear and calm morning will result in sub-freezing temperatures for lower valleys across northeast Utah and western Colorado. A Freeze Warning is in effect from midnight tonight to 9 AM MDT, highlighting regions most prone to sub-freezing conditions. The pressure gradient will weaken from west to east as the trough progresses eastward. Otherwise, mostly clear skies and calm winds are expected as cooler air settles in behind the trough. Cooler temperatures in the wake of the previously mentioned trough will bring another chilly morning on Monday.
A cold front will arrive Sunday night and could be impacting AUS as early as 05z tomorrow night with a northerly wind shift and some isolated showers. Upper air analysis this morning showed the subtropical ridge centered over western Mexico with the flow over Texas turning anticyclonically from westerly to northerly. There was a trough over the Rockies extending down to the Texas Panhandle. At the surface, high pressure extended over the eastern part of our CWA and winds were mainly light and variable. A cold front was pushing into the Panhandle. Sunday night the cold front will move into our area reaching our northern border around midnight and our southern border around sunrise Monday. Cooler air will move in behind the front with low temperatures Monday 5 to 10 degrees cooler than Sunday.
335 AM CDT Sun Oct 6 2019 (Today and Tonight) While a weak cold front extended from Sweetwater to Throckmorton early this morning, there was little cold air behind it. Cooler air will have to wait for a stronger cold front that will move into the Big Country mid to late afternoon, and through the rest of the region overnight. Overnight cold air will bring cooler temperatures in the 50s by morning.
301 AM CDT Sun Oct 6 2019 Upper level trough will swing through the area today producing cloudy conditions for most of your Sunday, but no precipitation expected and clearing by Sunday evening.
Winds will generally be from the northeast today becoming light and variable tonight as the center of high pressure moves over western Kansas.
1030 PM CDT Sat Oct 5 2019 Looking and feeling just like fall out there today, with quite the upper trough axis lifting north into North Dakota while a trailing cold front crossing central IA/MN as of 18Z. Plenty of rain still streaming north ahead of that upper wave/cold front, courtesy of strong warm advection ascent coupled with anomalous moisture (PWAT 1. Improvement should come everywhere this evening and tonight as much drier air works into the region and we lose the lower level cyclonic flow, though will have to watch some residual lower clouds likely clipping areas north of I-94 overnight.
in the lower to mid 60s. Surface analysis shows the cold front just moving over the lake. High pressure which builds in behind it will settle over the southeast cwa Monday night. The next storm to affect the region will be a deep trough that becomes a closed low.
Temperatures on Monday appear to not become as warm as previous forecasts due to a faster arrival of the upcoming cold front. Showers will expand in coverage overnight as the cold front is now projected to arrive Monday night.
An upper level trough will move through the region Sunday night into Monday. This will continue to allow cooler and drier, more fall like, weather to filter into the area. The ample sunshine that will occur will struggle to get daily highs into the lower 70s by mid week.
331 AM CDT Sun Oct 6 2019 A cold front slipped through central Illinois this morning, bringing clearing skies into the region. As High pressure builds into the Midwest Monday, dry conditions and seasonable temperatures will linger throughout the first half of the week. Winds will continue to remain elevated, however with the wind change, this will bring cooler feeling temperatures to the area. Shower activity will linger overnight in the far se CWA, before High pressure shifts overhead into the beginning of the work week. This is due to High pressure arriving overhead, and 500mb heights leveling out this week.
1247 AM CDT Sun Oct 6 2019 /06Z TAFS/ Cold front from Roby to Haskell at 530Z is expected move towards but stall just north of KABI this morning, before moving through around noon Sunday. An approaching cold front will slide into the Abilene are (KABI) by mid afternoon and to near San Angelo (KSJT) by sunset and shift winds around to the north. /issued 310 PM CDT Sat Oct 5 2019/ (Tonight and Sunday) A cold front will move into West Central Texas tomorrow and bring the potential for rain, along with cooler temperatures, for mainly the Big Country.
Thus, will leave the low PoPs (20% or less) in the forecast overnight. The dominant upper level ridge that has controlled our weather pattern over the last week will continue to break down as a weak front and upper level disturbance moves in from the northwest.
The better chances for storms will shift farther south this afternoon as the cold front surges southeast.
1233 AM CDT Sun Oct 6 2019 A cold front is just entering northwest Arkansas with some thunderstorms. Tonight Through Monday Night Satellite imagery was showing a strong cold front moving eastward through eastern KS/northeast OK.

Precip shud push south of the CWA somewhat quickly this evening as the upper trof approaches. Behind the front, cooler and drier air moves into the region. As the ridge builds east, southerly flow returns to the area with temps climbing quickly by mid week. Models are in fairly good agreement with a deepening upper trof over the western U. Much cooler air is expected to move into the region behind this front. Tilly Stratus will be exiting KCOU and KUIN by 05-06z as the cold front continues to push southeast resulting in clearing skies.
Much anticipated cold front should move steadily southeastward through the area during the day Monday with better convective coverage to ease the unusually dry 'flash drought' situation across the region. Any rain should end during the evening with noticeably cooler and drier air enters the region Monday night. Unfortunately, affects of cold frontal passage will be limited to only about 1 day.
Expect temperatures to drop into the lower 30s and there will be some frost.
Relatively zonal upper flow at the start of the period will quickly and significantly amplify by midweek as a deep trough develops over western North America.
Strong cold front will reach KHOB and KMAF around 06/23z. /issued 324 PM CDT Sat Oct 5 2019/ The first significant cold front of the Fall season is still on track to arrive tomorrow night.
Quiet with warmer conditions expected through the beginning of the week. A strong cold front brings strong winds and much colder conditions by the middle of the work week. Upper ridge amplified in the eastern Pacific will keep Nevada in a fairly light flow today, bringing light winds and clear skies with a bit more warming. Highs will be in the mid 50's northeast to the lower 70's southwest. The next trof begins to drop into British Columbia on Monday and this will start to flatten the western ridge.
Surface observations and radar this evening show a surge of Gulf moisture with dewpoints in the low to mid 60s continues spreading northwestward through the area, and currently stretches from Lawrenceburg to Celina. Cold front will move through the region later today, bringing showers and thunderstorms.
Otherwise fairly tranquil conditions are expected behind the cold front which as of this writing has cleared all TAF sites. The cold front continues to move south through the area. /issued 303 PM CDT Sat Oct 5 2019/ A few showers and storms have developed over the past hour near a cold front in central and north central Oklahoma. Overnight into Sunday morning, additional showers and storms should develop as 85H winds increase ahead of a trough to our northwest. Cooler and drier air will settle across most of the state Sunday into Sunday night as the aforementioned trough moves east of the area.

Temperatures will run just a few degrees cooler than yesterday.
Strong cold front will reach KHOB and KMAF around 06/23z and KFST by 07/03z.
Radar currently showing a few showers advancing west over the near coastal waters south of the lower Atchafalaya river. Temperatures currently are running in the low to mid 70s, and little further drop is expected through the overnight hours. weakening high pressure aloft will be sufficient to limit convective development and carrying no more than low end pops for mainly afternoon showers and thunderstorms. Much advertised cold front continues to be on track to move across the area tomorrow. Latest model output in good agreement in advancing a mid and upper level trof across the mid and lower Mississippi valleys Monday. Feature will be sufficient to push a cold front across the forecast area as and the day progresses limiting the heat of the last several days.
711 AM CDT Sun Oct 6 2019 The cold front appears to be just south of KPPQ to just south of KJEF this morning. Expect large scale ascent to increase ahead of the approaching trof.

Much cooler air is expected to move into the region behind this front.
/issued 402 AM CDT Sun Oct 6 2019/ Weak cold front is just about to clear the southwestern South Plains but on the heels of this front will be a second surge that will push across the forecast area through the day. This second front will help hold highs about 10 degrees cooler from yesterday and had to increase wind speeds in the grids above what the blend provided.
506 AM CDT Sun Oct 6 2019 Upper level trough will swing through the area today producing cloudy conditions for most of your Sunday, but no precipitation expected and clearing by Sunday evening.
Skies are clearing behind the cold front so I updated the zone forecast to expunge the early morning forecast that indicated rain likely. The low and mid level cold air that will trail the jet streak will bring some low clouds to northern lower Michigan tonight but that cold air does not get this far south or our CWA should remain mostly clear tonight. in the lower to mid 60s. Surface analysis shows the cold front just moving over the lake. High pressure which builds in behind it will settle over the southeast cwa Monday night. The next storm to affect the region will be a deep trough that becomes a closed low.
A warmer dry and breezy pattern takes hold of the northern rockies for the next few days.
402 AM CDT Sun Oct 6 2019 Weak cold front is just about to clear the southwestern South Plains but on the heels of this front will be a second surge that will push across the forecast area through the day. This second front will help hold highs about 10 degrees cooler from yesterday and had to increase wind speeds in the grids above what the blend provided.
Additional showers and storms will develop through the afternoon as a cold front presently near I-40 begins to surge south, with most favored area for storms trending into SE OK. The better chances for storms will shift farther south this afternoon as the cold front surges southeast.
1100 AM EDT Sun Oct 6 2019 A 1031 mb high pressure system centered east of the Delmarva stretches southwest to near the Mississippi River Delta. A weak inverted trough near the Bahamas has eroded some of the high's southern gradient. A weak trough of low pressure stretches from the Bay of Campeche to east of the Bahamas. This trough will linger to our south today and tonight. Meanwhile, high pressure will slowly build down the Eastern Seaboard and the Sunshine State.
344 AM MDT Sun Oct 6 2019 Upper low has pushed north of the Great Lakes in central Canada, but broad cyclonic flow remains across the northern central third of the CONUS. High pressure builds in tonight through Monday, with return flow setting up.
Today Through Monday Night An upper ridge continues over the southeastern U. with an upper trough over the Plains. The upper trough will expand eastward today and Monday into eastern sections. Showers and thunderstorms continue across the north along a cold front. High pressure moves in Monday to shut off the rain. Highs today will be in the upper 60s north to the lower 90s south and only in the upper 60s to lower 70s Monday.

Cooler air will have to wait for a stronger cold front that will move into the Big Country mid to late afternoon, and through the rest of the region overnight. Overnight cold air will bring cooler temperatures in the 50s by morning.
749 AM EDT Sun Oct 6 2019 A slow-moving cold front will approach from the west today, then push across Pennsylvania Monday.
Earlier update increased the temporal resolution of today's shower and thunderstorm chances, delaying the highest POPs along the front until the 4-7pm time frame. Additional showers and storms will develop through the afternoon as a cold front presently near I-40 begins to surge south, with most favored area for storms trending into SE OK. The better chances for storms will shift farther south this afternoon as the cold front surges southeast.
The increasing pressure gradient between an inverted trough to our south and ridge to our north has made it breezy along the coast.
while a cool area of high pressure remains in place through tonight and early Monday morning, skies are expected to clear out again behind the exiting trough aloft. The upper flow becomes more zonal as the trough aloft exits to the east. This will deepen a surface through along the lee of the Rockies and turn the surface flow to a more southwesterly direction which will help push the cooler air out of the region and create dry, warmer and breezy conditions on Monday.
Currently we have highs in the upper 50s across the board but reaching the low 60s in our southern and western counties isn't out of the question.
