235 PM MST Mon Jan 22 2018 A weak cold front from the west is slowly pushing cloudy skies and scattered sprinkles and flurries through portions of eastern Montana. Overall, the forecast is very benign with slightly warmer temperatures and dry conditions expected through the middle of the week.
324 PM CST Mon Jan 22 2018 The upper low is now over Missouri and a positively-tilted ridge is crossing the Rockies.
1008 AM CST Mon Jan 22 2018 Breezy and dry conditions are settling in across the region in the wake of last night/this morning's cold front, which morning surface analysis shows has pushed off the Texas coast. Expect elevated fire weather conditions across the area by early afternoon as relative humidities fall into the 20-30 percent range with conditions improving by this evening as winds decrease with the arrival of surface ridging from West Texas. Moisture levels and rain chances will increase going on into the weekend as onshore winds resume as the high moves off to the east.
An additional round of showers, and possibly a rumble of thunder or two, is expected to arrive this evening immediately ahead of a cold front currently positioned from about Springfield, Illinois south through Jackson, Tennessee. Any updrafts that can sustain themselves in a high shear/low instability environment will have the potential to develop downdrafts capable of bringing 50+ mph winds within the lowest 2000 feet off the deck down toward the surface. Showers will taper off through the night as gusty winds and cold air advection continue in wake of the front as the core of the low passes across the lower Great Lakes.
302 PM CST Mon Jan 22 2018 Winter storm starting to wind down over the area at 20Z as upper low over northern Missouri tracks toward western Illinois. Rest of the period looks quiet weatherwise with a warming trend through the work week as upper ridge moves into the region.
SHORT TERM (Tonight through Tuesday Night): Tonight, the arrival of drier air and thinning high clouds behind a Monday morning cold front will allow temperatures to cool into the mid 40s to lower 50s. Slightly cooler weather will continue on Tuesday, with high temps from the upper 60s to near 70 degrees.
139 PM CST Mon Jan 22 2018 A line of showers/storms along a pre-frontal trough continues to push E across Central Alabama this afternoon. The actual cold front is just west of Tupelo, MS, and will be passing through the forecast area later today/tonight. High pressure will dominate the weather across the Deep South for the remainder of the work week with the next chance of rain coming over the weekend as the next upper trough approaches from the west.
359 PM CST Mon Jan 22 2018 /Through Tonight/ Fire weather has been the big concern today across North and Central Texas as we've had strong gusty winds behind yesterday's cold front.
By late this afternoon and overnight the cold front will have pushed through and conditions will be benign afterwards with VFR conditions expected through the rest of the forecast.
210 PM CST Mon Jan 22 2018 A deep low pressure system will track from northern Missouri toward the Great Lakes region tonight and Tuesday. Vorticity lobes wrapping around the upper low within a deep cyclonic flow as well as the passage of a true cold front pushing across the Ozarks region will bring light precipitation mainly to central Missouri through this evening. This light rain could become mixed with or change to a light wintry mix of rain, snow and possibly freezing drizzle later this evening before the precipitation ends. A chilly and continued blustery conditions are in store for Tuesday as the low pressure system pulls away. A warming trend will return mid to late week as an upper level ridge builds eastward and southerly winds return.
Elevated fire weather conditions will continue through sunset before diminishing as surface ridging spreads farther west from the Texas Caprock. A few locations may briefly reach freezing around sunrise. After a cool start, temperatures will warm into the low to mid 60s on Tuesday under mostly sunny to partly cloudy skies.
110 PM MST Mon Jan 22 2018 Water vapor shows upper low over northern IA with narrow upper ridge over the far western Dakotas, and weak upper trof over the Northern Rockies. At the surface, low center nearly stacked with upper low. Weak trof over the Northern Rockies will quickly move into the Northern Plains tonight, with brief light snow expected from NE WY into far SW SD and a very small window of upslope in the northern Black Hills. Skies will clear from west to east Tuesday behind departing trof with highs in the 30s to lower 40s and some breezy northwest winds.
1251 PM EST Mon Jan 22 2018 Warm today, cold front later this evening/tonight. Cooler and windy behind the front. Mid level waves pass through mid week, but turning warmer again late week. Cold front will be east of the forecast area to start the period, with cold air surging in behind the front. Have a non- diurnal temperature trend in at higher elevations Tuesday, with a transition to from rain to snow as an upper level low crosses the Great Lakes. Across the lowlands, we should see mostly rain showers Tuesday before changing over to snow through the late afternoon and evening.
1244 PM EST Mon Jan 22 2018 A warm front will lift north across the forecast area today producing scattered showers and well above normal temperatures. A strong cold front will move across the area tonight ushering in more seasonal conditions. Models continue to move a low pressure system, now near Kansas City, across the Central Great Lakes early Tuesday. Expect rain to spread across the forecast area overnight ahead of the system The low will track NE across the Central Lakes early Tuesday, forcing another cold front across the forecast area. The short term begins Tuesday night with models showing low pressure in srn Quebec and New England with wrap around moisture and cold advection across the area. Temps at 850mb average around -7 to -8C on the NAM and ECMWF but are a couple degrees warmer on the GFS.
238 PM CST Mon Jan 22 2018 As the upper level low that has been dominating the synoptic pattern across mid-America for the past couple of days exits Kansas to the east and makes its way across the Mississippi and Ohio Valleys tonight and tomorrow, the tightened pressure gradient will begin to ease off this evening bringing wind speeds back down overnight tonight. Over the next few days, expect a gradual warming trend as an upper ridge pattern sets up across the western half of the CONUS through the middle of the week.
VFR conditions expected through the period behind cold front that pushed through early this morning. Aviation conditions are improving across South Texas as cold front moves through the region, clearing fog and lifting cigs. A cold front is currently tracking across South Texas towards the coast early this morning. Today will be cooler, with highs topping out in the upper 60s to lower 70s. Cooler and drier conditions develop tonight under mostly clear skies and weak winds.
A transition from VFR to MFR conditions will progress from west to east as we go through the day and into the overnight hours just ahead of an incoming cold front.
113 PM EST Mon Jan 22 2018 A cold front will swing through the Ohio Valley today bringing showers and a chance of thunder this afternoon into the evening.
150 PM EST Mon Jan 22 2018 A low pressure system will move into the region bringing continued chances for scattered showers into tonight and Tuesday.
Temperatures will be slow to fall this evening as we remain under the influence of strong southerly flow, which will also allow the strong and gusty winds to persist across the high terrain. Most places will see liquid precip but the highest peaks will transition over to snow as temps drop below freezing later in the day.
344 PM EST Mon Jan 22 2018 Low pressure will track northeast through the Great Lakes tonight through Tuesday, forcing a cold front east across the area.
1147 AM EST Mon Jan 22 2018 Temperatures will remain mild, through Tuesday, along with periods of rain, along and ahead of an approaching cold front. Rain will increase tonight in advance of a cyclone moving toward Western New York. Upper level heights fall as a broad trough moves into the northeast US. Lawrence Valley Tuesday evening will move east to New Brunswick and drag a cold front through our area.
1137 AM CST Mon Jan 22 2018 18Z TAFS The line of showers and thunderstorms associated with a cold front has cleared the region. Behind the front, cooler and drier air filtering across the region, along with clearing skies. This band is occurring along a pre-frontal trough that extends from central LA southwest to near Galveston. Cooler temperatures follow behind the front along with a sharp drop in dewpoints. Convection was being aided by good divergence aloft southeast of a large upper level low pres system over KS. A strong 130 KT jet streak transiting the base of the trough is helping accelerate the system eastward early this morning.
As for fire weather, cooler temps and higher RH will offset the strong winds for the most part.
359 PM EST Mon Jan 22 2018 Mature dry slot has been fully entrained into the stacked cyclone presently situated over Iowa at 20z.
1135 AM EST Mon Jan 22 2018 Unseasonably warm conditions are expected until the passage of a cold front tonight. The Plains low is still projected to dig across the Great Lakes by early Tuesday with Monday night cold frontal passage for the Upper Ohio. Seasonable temperature in the wake of the front is expected to change rain showers to snow on Tuesday with upper support via the crossing mid level trough.
955 AM MST Mon Jan 22 2018 Water Vapor shows upper low over north central Kansas. Upper level ridge builds across the northern plains through the middle of the week, with dry weather and warm temperatures.
246 PM CST Mon Jan 22 2018 A deep area of low pressure will continue to slowly rotate east- northeast toward the Great Lakes region tonight into Tue. Temperatures Tue/Wed time frame will return to more seasonal values as a chilly high pressure system pushes into the Plains.
The rains are ending from west to east ahead of the cold front. A cold front in association with this low is located across western Arkansas down across the ArkLaTex region and into the Texas Hill Country. Highs today should reach into the the lower 60s in the Delta to the lower 70s in the Pine Belt. As the upper system starts to pull off to the east, high pressure at the surface will move in this evening.
Temperatures remain on track with highs in the low to mid 60s. Some warming should take place behind the rain with the cold front lagging behind in eastern Arkansas. A cold front will push through Middle Tennessee today.
Strong low pressure centered near Kansas City will move east to eastern Iowa late today and across the great lakes late tonight and Tuesday. The rest of the work week will be dry as high pressure pushes across the region. The showers were well ahead of the cold front. Low pressure was centered over Iowa. The low is expected to continue to track northeast and eventually push the associated cold front across the area tonight. However with the arrival of the cold front and lingering lower level moisture pops will need to remain in the forecast this afternoon. Models indicate a secondary cold front will move our way by late evening.
332 PM CST Mon Jan 22 2018 The cold front is moving through this afternoon and had some storms earlier, but mostly just a broken line of showers across the area.
238 PM CST Mon Jan 22 2018 Pacific high pressure rebuilding across the region has allowed for an enhanced pressure gradient and west winds around 20 mph with higher gusts. Temperatures overnight to fall into the 30s areawide with most areas remaining above freezing.
1222 PM EST Mon Jan 22 2018 Unseasonably warm conditions are expected until the passage of a cold front tonight. The Plains low is still projected to dig across the Great Lakes by early Tuesday with Monday night cold frontal passage for the Upper Ohio. Seasonable temperature in the wake of the front is expected to change rain showers to snow on Tuesday with upper support via the crossing mid level trough.
/issued 1032 AM CST Mon Jan 22 2018/ Current temperature trends running a little warmer than forecast and therefore went ahead an bumped temps up about 3 to 5 degrees with most areas forecast to climb into the low to mid 60s today. Winds will be on the increase by late morning with the approach of another re-enforcing cold front.
305 PM CST Mon Jan 22 2018 Water vapor imagery showing upper low drifting slowly e-ne across northeast MO this afternoon. Trimmed the highs for Tuesday over the expected heavy snow area over south central MN into western WI.
At 1 pm EST a surface cold front extended southward through eastern MS, southeast LA, and into the western Gulf of Mexico from a 995 mb low centered over IA. However, lows in the upper 40s are expected in southeast AL and the western FL Panhandle, where the cold front will have moved through before daybreak. Ahead of the front, areas of fog will be possible, mainly between the time when the rain ends and the cold front arrives.
255 PM CST Mon Jan 22 2018 The strong low pressure system that brought snow and wind to north central Nebraska will continue to push east tonight. Expect low temperatures to drop into the low to mid teens. Meanwhile, high pressure will slowly build southward into the central Plains bringing a return to drier and quieter weather.
Temperatures remain on track with highs in the low to mid 60s. Some warming should take place behind the rain with the cold front lagging behind in eastern Arkansas.
The wind and weather over the next seven days will be governed by the migratory continental anticyclones and associated mean sea level pressure gradients between them and the Caribbean trade wind belt.
As the upper trough swings east, just north of the state, some 3-5k ft clouds will be seen across northern AR terminals this afternoon through the overnight hours. Surface analysis shows the dry line associated with the system now getting into western Arkansas with cold front trailing several hours behind. Cooler and drier air will quickly overspread the state in the wake of this system but air mass will be of Pacific origin so even though temperatures will be cooler, readings will still average close or a few degrees above normal. Upper low sitting over central Kansas this morning is expected to pivot to the northeast today. High pressure will dominate for Tuesday.
1032 AM CST Mon Jan 22 2018 Current temperature trends running a little warmer than forecast and therefore went ahead an bumped temps up about 3 to 5 degrees with most areas forecast to climb into the low to mid 60s today. Winds will be on the increase by late morning with the approach of another re-enforcing cold front.
226 PM CST Mon Jan 22 2018 Tonight through Tuesday: Latest rap and satellite analysis showed the upper trough moving into the Mississippi Valley from the Plains. The cold front was tracking across our eastern counties with the rain east of the forecast area. For the period expect quiet conditions as the upper trough axis exits to the east as we get into a zonal flow pattern on Tuesday.
Dry air in the wake of this morning's cold front will keep skies clear through the period. Current moderate northerlies to begin to weaken later this afternoon as high pressure moves in from the west. /ISSUED 1008 AM CST Mon Jan 22 2018/ Breezy and dry conditions are settling in across the region in the wake of last night/this morning's cold front, which morning surface analysis shows has pushed off the Texas coast. Expect elevated fire weather conditions across the area by early afternoon as relative humidities fall into the 20-30 percent range with conditions improving by this evening as winds decrease with the arrival of surface ridging from West Texas. Moisture levels and rain chances will increase going on into the weekend as onshore winds resume as the high moves off to the east.

A relatively dry cold front is still anticipated to swing through the Northern Rockies on Saturday.
327 AM PDT Fri Sep 8 2017 Cooler through Saturday with better chances for afternoon and early evening thunderstorms in the mountains and deserts.
236 AM CDT Fri Sep 8 2017 There have been no changes in the forecast for the Ozarks region with mild fall like weather in place thanks to high pressure over the area. Todays temperatures will be a bit warmer than the past few days with low 80s expected. VFR conditions are expected through the forecast period as high pressure remains over the region.
Otherwise, VFR conds wl prevail thanks to high pressure.
An upper trough will bring a slight chance of showers today.
Long period swells from Katia will continue to move towards the lower Texas coast later today into tonight. Have issued a high surf advisory and a statement for high risk of rip currents as well as minor tidal overflow for the lower Texas coast today through tonight. /issued 406 AM CDT Fri Sep 8 2017/ SHORT TERM (Today through Saturday): Satellite and radar images continue to show a band of convection offshore the extreme northeast Mexican coast extending northward into the offshore waters of the lower Texas coast early this morning. Low to mid level easterly winds across the northwest Gulf of Mexico between a 500mb ridge across Texas and Hurricane Katia across the southwest Gulf of Mexico will continue to bring a surge of higher precipitable water values westward into northeast Mexico and the lower Rio Grande valley today.
424 AM CDT Fri Sep 8 2017 An upper level trough over the northeast United States will continue to slowly lift out to the northeast through the weekend.
High pressure is just to our north over the OH Valley and will help to keep conditions very similar to last night. The lingering northerly flow and clear/mostly clear skies will have highs only reaching the upper 70s on Friday with overnight lows cooling down to the low/mid 50s.
300 AM EDT Fri Sep 8 2017 High pressure will extend across North Carolina today through tonight. A dry backdoor cold front will drop southward through the area late Saturday into Saturday night.
Upper ridge moving east under influence of approaching short wave. The wave also brings in cooler air and the ridge axis moving allows cloud cover to block insolation, resulting in much cooler air most location.
427 AM EDT Fri Sep 8 2017 High pressure north of the forecast area will direct dry air into the area through Saturday night.

619 AM EDT Fri Sep 8 2017 High pressure north of the forecast area will direct dry air into the area through Saturday night.
Rain ends and clouds exit the region tonight as high pressure builds across the Upper Great Lakes into Friday. Warmer Friday with highs in the low to mid 60s and sunny skies. Winds will become nearly calm as high pressure builds in, and while skies should remain mainly clear overnight there is a risk for fog/stratus to develop across portions of the Northland. This wind direction will result in slightly cooler temperatures along the north shore, but otherwise highs in the low to mid 60s expected. Upper level ridging will be affecting the forecast area Friday night through Saturday night and have a rain free forecast.
553 AM EDT Fri Sep 8 2017 An upper level trough extending from eastern Canada southwest into the Great Lakes will gradually move off to the east through Saturday. This will allow high pressure to build into the region from the north.

1219 AM CDT Fri Sep 8 2017 Aloft: Weakening NW flow was over the Cntrl Plns with a ridge over the Wrn USA and a trof in the E. The Wrn ridge will be forced E over the Plns thru tomorrow. The last 2 runs of the NAM/GFS/RAP/EC suggest some spotty shwrs and embedded tstms will develop over Wrn/Cntrl KS at the nose of the low-lvl jet. Svrl degs warmer than today. it appears the high/ridge will be nudged over the Plns as a deep trof moves onshore in the W. Temps will average just a touch warmer than normal.
357 AM EDT Fri Sep 8 2017 A weak area of low pressure will swing across the Northeast through the first half of the weekend.
Expect we will be a degree or two warmer at most sites which will keep most areas above records. Saturday morning will again see cooler than normal temperatures, but much of the area will be in the middle to upper 50s. Trended morning lows on the cooler side of guidance.
Cooler and breezy weather will prevail for the weekend thinning the smoke out. Will be monitoring visibilities down in the lower Columbia Basin this evening to get a better idea on the degree of improvement coming our way. improvement should be gradual with the more significant improvement occurring Saturday as a cold front passes through.
