Ridge aloft today will give way to stronger moist southwest flow aloft overnight into tomorrow. Tonights lows will stay in the lower 50s for elevated locations across the plains, though river valleys will probably make the lower 40s. not that cold) cold front moves into the area Thursday night.
1134 AM PDT Wed Oct 26 2016 The next couple of days will be wet as a warm front moves over the region today and Thursday.
/issued 638 AM CDT Wed Oct 26 2016/ At 3AM, Temperatures are rather mild across the Mid-South, ranging from the lower 50s to near 60 degrees. A couple of mesoconvective systems are ongoing downstream of the main trough axis, with cirrus clouds beginning to overspread the Mid-South. The main storm track will remain removed well to our north over the next seven days, as a large ridge of high pressure builds over the southern U.
343 PM EDT Wed Oct 26 2016 High pressure will prevail through Thursday.
253 PM EDT Wed Oct 26 2016 Low pressure will bring rain to the region tonight and Thursday.
A low pressure system moving east across the Great Lakes region will continue to bring rain through this evening and mixed rain and snow north of interstate 96.
Strong high pressure building over the region will lead to warming temperatures through the end of this week with record highs possible at some locations on Thursday. Latest streamline analysis shows an anticyclone in the eastern Pacific with a ridge axis extending northward through Sonora and into the Desert Southwest. Global models are indicating copious amounts of upper-level moisture will be transported into Southwest in the return flow around the eastward-advancing ridge. Minor adjustments were made to the high temperatures in these areas. By Thursday night, an Pacific low pressure trough reaches the California coast helping to displace the upper level ridge eastward over New Mexico and Texas.
/This evening through Thursday/ The main forecast concern is the low stratus deck hanging around through tomorrow morning. Inversion continues to strengthen this evening into the overnight hours trapping the low stratus deck. /Thursday night through Wednesday/ High pressure ridge will be stretched over central Iowa mid Thursday morning then will move slowly east during the day. Warm advection will be ongoing to the west of the high pressure however a steep inversion setting up between 900-850 mb and will limit temperature recovery. Also the steep inversion combined with the light flow directly under the high pressure may slow the erosion/departure of stratus over the east to northeast portion of the area.
339 PM EDT Wed Oct 26 2016 High pressure will continue to extend over Eastern North Carolina through tonight.
1211 PM CDT Wed Oct 26 2016 VFR conditions expected to persist throughout the remainder of the day, as upper level ridging continues to keep things dry. Therefore, this low level moisture, along with radiational cooling should allow for patchy fog to form for the northern terminals tomorrow morning. /ISSUED 1100 AM CDT Wed Oct 26 2016/ Southwestern-based upper ridging will continue its eastward expansion over the state. This will be the main reason for these mainly clear and subsequently warmer week days. Nil rain chances and slightly warmer today with middle 80 maximum temperatures.
A weak cold front may move into the Big Country late tonight. Behind this trough, a very weak front will move into our northern counties by this evening.
Issued by National Weather Service New Orleans LA 427 PM CDT Wed Oct 26 2016 The main upper level ridge axis has shifted south and currently extends west to east across the northern portion of the Gulf. high pressure over the southeastern states was maintaining east to southeasterly surface wind flow and increasing dewpoint temperatures. With the low temperatures expected to be near the surface dewpoints, some patchy fog will be possible after midnight through about mid morning on Thursday. Highs are expected to be warm again on Thursday, generally in the lower to mid 80s.
221 PM CDT WED OCT 26 2016 Main concerns in this forecast cycle are chances of rain with the current upper system and cold front affecting the region. The cold front is located in eastern OK to western MO, while the upper system has made progress to western AR to central MO.
A warm front extended across central North Dakota. Low clouds and fog that formed along and east of the warm front earlier Wednesday have been slowly eroding east at 5 to 10 mph through the day. This pattern will continue this evening with the low clouds retreating east across east central North Dakota with the warm front. Meanwhile the cold front across the northwest will move through the region after midnight. The HRRR model runs show shallow cool northwest flow behind the cold front that will likely support stratus and some possible fog back into the north. On Thursday with a complete airmass exchange in the wake of the cold front expect partly to mostly sunny skies that will allow good mixing. As a result mild temperatures are forecast well into the low to mid 70s southwest to the 60s central.
A cold front and weak low pressure system will move through the area overnight, bringing showers and a few rumbles of thunder to the area. High pressure will build in tomorrow, bringing a return to dry weather through the early part of the weekend.
248 PM CDT Wed Oct 26 2016 The cold front that moved across the region late last night and early this morning has continued its slow southeastward movement towards the Kansas/Oklahoma border this afternoon. Tonight as the surface cold front slowly pushes southward of the Kansas/Oklahoma border, high pressure will briefly clip the region and allow for clear skies and ample radiational cooling to occur. With return flow expected to develop Thursday/Thursday night, as lee troughing becomes established along the northern and central Rockies and upper-level ridging builds across the region, low- level south to southwesterly flow will usher in warming temperatures aloft, with summer-like thickness values.
A large mid-upper tropospheric ridge will prevail through Thursday, and this will lead to continued above-average temperatures. A high pressure ridge will shift from northwest to southeast across the Central Plains tonight, and this will result in a prolonged period of light winds tonight. The drier airmass, very light winds, and clear skies should allow temperatures to dip down to the lower to mid 40s most locations (especially along/north of Arkansas River). On Thursday, the leeside trough will redevelop with a shift in the surface wind back to the south/southwest. High pressure ridge axis rebuilds strongly onto the plains Thursday.
141 PM MDT Wed Oct 26 2016 Broad upper ridge covers the western CONUS. Mild and dry weather will continue as upper ridge axis moves over the central CONUS Thursday. Low-level flow will become southwesterly tonight and increase on Thursday, bringing warmer air to the region.

534 PM EDT Wed Oct 26 2016 CORRECTED TO ADD AVIATION SECTION Skies are partly cloudy with temperatures averaging in the lower to mid 80s along the Florida Keys. Meanwhile, local radars are only detecting a few light showers on the distant waters beyond 20 nm south of the Lower Keys. Surface wise, our area lies between lower pressure in the northwest Caribbean sea and a massive and formidable region of high pressure to our north.
631 PM EDT Wed Oct 26 2016 High pressure will continue to extend over Eastern North Carolina through tonight.
451 PM MDT Wed Oct 26 2016 Broad upper ridge covers the western CONUS. Mild and dry weather will continue as upper ridge axis moves over the central CONUS Thursday. Low-level flow will become southwesterly tonight and increase on Thursday, bringing warmer air to the region.
We expect to gradually wane into early evening as the upper trough moves farther to the east. Vestiges of the upper trough/weal forcing exiting to the east with some deformation over northwest Wisconsin. Slow clearing into Thursday as the high retreats and southerly flow develops.
449 PM EDT Wed Oct 26 2016 Low pressure will bring rain to the region tonight and Thursday.
Weak surface ridging across the Panhandle into the western South Plains will include the Rolling Plains tonight. /issued 621 AM CDT WED OCT 26 2016/ Surface cold front is poised to the NW of KPVW about 60NM. Surface cold front should make it to our NW corner by about 12Z with initial southerly push across the west. Insofar as temps go, not a whole lot of difference is expected in the highs though lows may range from 45 in the NW to 60 SE.
The surface reflection of the trough, a cold front, is presently sweeping southeast through eastern Kansas and Missouri; currently along a line from Kansas City to Kirksville. Despite the cold front sweeping southeast today, we expect neither more rain or even cold temperatures thanks to the ridge to our west. The ridge placement will keep the storm track well to our north through the weekend into the middle of next work week.
120 PM MST WED OCT 26 2016 Strong high pressure building over the region will lead to warming temperatures through the end of this week with record highs possible at some locations on Thursday. Latest streamline analysis shows an anticyclone in the eastern Pacific with a ridge axis extending northward through Sonora and into the Desert Southwest. Global models are indicating copious amounts of upper-level moisture will be transported into Southwest in the return flow around the eastward-advancing ridge. Minor adjustments were made to the high temperatures in these areas. By Thursday night, an Pacific low pressure trough reaches the California coast helping to displace the upper level ridge eastward over New Mexico and Texas.
