611 PM CDT Fri Apr 30 2021 High pressure overhead will keep light winds and plenty of sunshine overhead for the remainder of the day. Lows will bottom out in the low to mid 50s.
/issued 142 PM CDT Fri Apr 30 2021/ Showers developing across the Permian Basin and Concho Valley will begin to move northward toward the southern sections of the forecast area this afternoon and evening as the persistent and nearly- stationary upper low over Chihuahua begins to rotate to the east- northeast across Coahuila on Saturday and central Texas on Saturday night. Precipitation will favor southern zones tonight and southeastern on Saturday following the movement of the upper low and its associated lift. Persistent showers and cloud cover southeast will result in the coolest high temperatures there on Saturday while northwestern zones where skies will be clearing will run about 10 degrees warmer than the cooler southeast.
540 PM MDT Fri Apr 30 2021 Broad & flat upper-level ridging will continue to support warm and dry conditions across the majority of the area early in the period with many areas reaching 80 deg F this afternoon. Daytime highs on Saturday will be quite warm once again, before ridging breaks down and upper-level difluence overspreads the central Rockies ahead of the next short wave trough.
921 PM EDT Fri Apr 30 2021 Freeze and frost conditions are expected tonight before dry and warmer weather this weekend. Wind gusts have diminished below advisory criteria in the ridges with loss of daytime mixing. Decreasing wind speeds and clearing sky this evening will allow temperatures to drop to near or below freezing overnight. A Freeze Warning continues north of Pittsburgh and across the ridges where temperatures below 32F are expected. Dry weather is then expected through the weekend with a warming trend in temperature as ridging amplifies over the region.
An upper level trough will cool temperatures slightly inland and bring isolated light showers and drizzle to the north on Saturday.
As for their impact to the forecast, they may slow the rate of radiational cooling this evening, but temperatures overnight will still fall into the lower 50s. The transitory mid-level ridge to our southwest will shift eastward across the region on Saturday, with mostly sunny skies and the onset of very light southeasterly return flow promoting high temperatures in the u70s-l80s.
856 PM CDT Fri Apr 30 2021 High pressure remains over the Mid-South this evening. Dry conditions will persist through Saturday as high pressure builds to our north.
albeit several degrees warmer via continued airmass modification (assoc/w strong, unimpeded insolation).
The first system will move through late tonight and early Saturday, bringing showers and a cold front. A Pacific cold front will cross the area late tonight and early Saturday, followed by northwest surface winds increasing to 15-25 kts with gusts over 30 kts by afternoon, strongest from KMUO through KTWF.
Elongated upper ridge currently centered over the western US as a cut off low continues to sit over the SW US/northern Mexico, cut off from the prevailing flow. Warm air advection continues in earnest today as a thermal ridge will is centered over the forecast area this afternoon. Upper trough axis centered just off the Pacific NW coast will pivot through the region late Saturday.
919 PM EDT Fri Apr 30 2021 A narrow high pressure area will build across the Commonwealth later tonight and Saturday, to bring dry weather and diminishing winds.
This is due to nearby high pressure ridge settling into the Southeast States by sunset Saturday. Seasonably cool temperatures are expected tonight, with lows in the lower 40s in eastern IL, and upper 40s to around 50 degrees in west central IL.
1023 PM EDT Fri Apr 30 2021 Currently - The tail end of a midlatitude trough moving off the Atlantic coast extends southwestwards into Central Florida. Quite weak lower to mid level ridging is aligned across the area. However there is a cloud line near at least the Lower Keys. Short Term Update - While the mid latitude trough will continue to work its way eastwards through the overnight period, the tail end will linger near Central Florida through the overnight period. Forecast soundings suggest that the low level inhibition may mostly dissipate towards morning. A trough near Florida will keep winds light and variable across much of Florida Keys waters.
627 PM CDT Fri Apr 30 2021 Warm front/wind shift will move across the Highway 83 corridor this evening with winds shifting from southerly to westerly. Saturday will be another warm, breezy, and dry day as the upper- level ridge lingers over the northern CONUS; however, conditions will not be quite as extreme as they are today. Sky cover is also expected to increase throughout the day as the ridge axis moves east, which will work to limit boundary layer mixing and how warm temperatures can get.
744 PM EDT Fri Apr 30 2021 High pressure moves overhead tonight leading to cold, frosty conditions for Saturday morning. High pressure quickly moves south of the Ohio Valley on Saturday allowing southerly flow to develop and moderating temperatures through the weekend.
1032 PM EDT Fri Apr 30 2021 Low pressure will track into the maritimes tonight. High pressure will build south of the region on Saturday.
938 PM EDT Fri Apr 30 2021 High pressure moves overhead tonight leading to cold, frosty conditions for Saturday morning. High pressure quickly moves south of the Ohio Valley on Saturday allowing southerly flow to develop and moderating temperatures through the weekend.
238 AM EDT Sat May 1 2021 Upper troughing will progress from the Eastern Seaboard into the western North Atlantic Ocean while downstream ridging is maintained from the southern Gulf of Mexico through the Greater Antilles. Temperatures throughout the short-term period should average 3-5 degrees above the seasonal mean, with highs mostly in the upper 80s to around 90 (slightly cooler within ~20-30 miles of the coasts), and lows in the 60s (inland) and 70s (urban and coastal areas).
323 AM CDT Sat May 1 2021 Upper low, currently west of Big Bend, TX this morning, will continue to lift northeast through central Texas today, moving into the ARKLATX region by mid-day Sunday.
1126 PM MDT Fri Apr 30 2021 Broad & flat upper-level ridging will continue to support warm and dry conditions across the majority of the area early in the period with many areas reaching 80 deg F this afternoon. Daytime highs on Saturday will be quite warm once again, before ridging breaks down and upper-level difluence overspreads the central Rockies ahead of the next short wave trough.
1202 AM MDT Sat May 1 2021 06Z TAF CYCLE The upper low well to our southeast will lose it's grip on our far southeast area today, including KROW, which will finally have some sunshine.
1126 PM CDT Fri Apr 30 2021 Fair and dry weather is expected through Saturday night due to nearby high pressure settling into the Southeast States by sunset Saturday. Seasonably cool temperatures are expected tonight, with lows in the lower 40s in eastern IL, and upper 40s to around 50 degrees in west central IL.
This low will open up into a trough as it lifts across NE TX Sunday and exits the state.
328 AM EDT Sat May 1 2021 High pressure builds in for the weekend.
As for their impact to the forecast, they may slow the rate of radiational cooling this evening, but temperatures overnight will still fall into the lower 50s. The transitory mid-level ridge to our southwest will shift eastward across the region on Saturday, with mostly sunny skies and the onset of very light southeasterly return flow promoting high temperatures in the u70s-l80s. As the ridge axis crosses the region Saturday evening, winds aloft will back to the southwest and strengthen considerably early Sunday morning, as a cutoff upper low lifts northeastward through central TX. Southeasterly flow in the low-levels will gradually increase throughout the day, as the the cutoff upper low opens into a negatively-tilted wave and tracks northeastward into northern AR/southern MO.
248 AM CDT Sat May 1 2021 This morning, southerly closed upper low is observed rotating across the Rio Grande Valley, lifting Gulf moisture into southern OK. Meanwhile, midlevel moisture is streaming over the northern CONUS, rounding the short wave ridge and dropping into the central plains in the form of high clouds. Highs are forecast to be a few degrees warmer than yesterday into the middle 80s, given the ample warm advection and warmer start to the morning with readings in middle 50s. Aforementioned Gulf moisture in the form of low clouds advects northward into northeast Kansas late this evening as the closed low shifts into Texas. Southerly winds remain on the gusty side overnight, sustained from 10 to 15 mph, resulting in a mixy boundary layer and lows Sunday morning on the warmer side in the low 60s.
626 PM EST Fri Jan 26 2018 High pressure along the Eastern Seaboard moves out to sea tonight and Saturday.
644 PM EST Fri Jan 26 2018 High pressure will slide off the East Coast through Saturday.
Moisture will continue to increase over Arkansas ahead of a cold front. The cold front will move through the state Saturday with showers.
We did drop DRT down to 1/2 mile between 08-14Z as upslope flow will keep the low-levels saturated. We do expect a cold front to move through tomorrow morning and this should help visibilities to improve. Upper air analysis this morning showed a ridge over the eastern half of the country and trough over the west with west-southwesterly flow over Texas. At the surface, there was high pressure centered over the southeastern US and winds across our CWA were light from the south to southeast. There was a cold front stretched across New Mexico. The upper level trough over the west will move across the plains during the is period. This will bring the cold front through Texas.
934 PM CST Fri Jan 26 2018 Removed the slight chances of freezing drizzle across NW MN the rest of the night. Question is how much, if any, freezing drizzle is reaching the ground. Think that there will be some increasing chances later on this evening as time-height charts show an increase in omega in the low level saturated layer. Measurable snow chances look highest in the north, with flurries more likely south of the Highway 2 corridor.
644 PM EST Fri Jan 26 2018 A cold front will approach and move through the region Saturday into Saturday night.
VFR conditions will be present through the night with high pressure slowly moving to the east.
/issued 307 PM CST Fri Jan 26 2018/ Skies remain sunny over much of the forecast area this afternoon with temperatures in the lower 60s. Currently, a cold front extends from northern Minnesota through central Kansas and into eastern New Mexico. The cold front will move into the forecast area on Saturday with more rain expected. The cold front will move out of the region Saturday night with rain ending from northwest to southeast.
557 PM CST Fri Jan 26 2018 Winds will remain strong and gusty through the afternoon hours as the pressure gradient ahead of a cold front remains tight.
602 PM EST Fri Jan 26 2018 High pressure should maintain dry weather until rain chances return with a Saturday cold front. As the upper-level trough catches up to the surface feature, moisture will increase further fueling showers through the Ohio Valley. The aforementioned stream of moisture in concert with a favorable upper-level trough and jet combo will be enough to support categorical POPs across the forecast area. Despite the high POPs, QPF remains fairly light with an areal average of about two to four tenths projected.
506 PM EST Fri Jan 26 2018 High pressure will slide off the East Coast through Saturday.
531 PM CST Fri Jan 26 2018 Today's warmup was the result of a warm front surging northward and scouring away the stratus and fog that had been in place. However, a cold front sits just west of the CWA and is poised to begin moving through this evening and tonight. As the parent low tracks across southwestern Ontario overnight, it will drag the cold front through the CWA and bring the next wave of cold temperatures in its wake. The better moisture will be closer to the low, and there may be enough along the International Border to lead to patchy freezing drizzle or light snow showers as the cold front pushes through and behind the front. On Saturday, a trough/secondary cold front will work across the CWA as the cold air continues to pour into the region.
554 PM EST Fri Jan 26 2018 High pressure will gradually slide offshore tonight. Warmer air returns for the start of the weekend as a southwesterly flow develops ahead of an approaching frontal system.
906 PM EST Fri Jan 26 2018 High pressure should maintain dry weather until rain chances return with a Saturday cold front. As the upper-level trough catches up to the surface feature, moisture will increase further fueling showers through the Ohio Valley. The aforementioned stream of moisture in concert with a favorable upper-level trough and jet combo will be enough to support categorical POPs across the forecast area. Despite the high POPs, QPF remains fairly light with an areal average of about two to four tenths projected.

We dont expect much accumulation from the fast moving snow showers, but some of the higher hills may briefly see slush covered roads and low visibility. A broad upper and mainly dry trof remains in control over the region today. Will continue to be windy tonight and Saturday morning along western foothills and into Billings as lee sfc troffing develops behind departing system in southwest Canada. Saturday weather is further complicated by a back door cold front dropping into eastern zones Saturday evening and set up a baroclinic zone for Saturday night.
954 PM CST Fri Jan 26 2018 Northwest flow will gradually decrease across the area this evening as cold front shifts east of the forecast area.
Strong downsloping, along w/strong subsidence should drive dew points much lower than MOS suggests, and actually most of the consensus temperature guidance has trended warmer from 24 hours ago. On Sunday, a significant upper-level trough will dig southeastward into the Great Basin, w/increasingly difluent/moist southwest flow becoming established over the CWA.
514 AM EDT Sat Oct 7 2017 Warm front lifts north across Northern New York and Vermont today. More rain showers are expected Sunday as a cold front crosses the area. Warm front lifts north across the area today and we will be under strong warm air advection through early Sunday morning. Maximum temperatures will generally be in the 70s across the area, possibly warmer if we clear out enough for some decent sunshine. Feel most of our area will have measurable precipitation as cold front crosses our forecast area west to east. Early afternoon highs will be in the mid to upper 70s, this again will depend on amount of clearing behind cold front when showers end.
344 AM EDT Sat Oct 7 2017 A stalled front extending from Western New York, to near Altoona and Baltimore this evening will lift slowly to the north as a warm front late tonight bringing another late taste of summer-like weather for us on Saturday. A fast moving upper level disturbance and weak surface cold front will bring showers to the region Saturday night and early Sunday.
As an upper level trough and strong jet aloft remain over the area this morning, the threat for high winds continues for the Little Rockies today. Winds are expected to relax tonight, though another breezy day will follow on Sunday as the upper trough deepens further across the Western U. This will lead to height falls over northeast Montana and thus expecting cooler temperatures.
A 300 mb jetstreak was located over western Colorado at 12Z and height falls ahead of the mid level trough over the Rockies were in excess of 50 meters at 500 mb. Look for highs Saturday mostly in the lower 70s. Sunday will be warmer for locations ahead of a cold front that will move from northwest to southeast through the local area on Sunday.
356 AM CDT Sat Oct 7 2017 Light rain showers will taper off through the early morning hours as the responsible upper level low and surface cold front continue to track further off to the east. with temperatures returning to the low to mid 70s across the majority of the forecast area.
304 AM CDT Sat Oct 7 2017 A cooler, drier air mass is spreading across the forecast area early this morning behind last evening's cold front. As a result temperatures will remain on the mild side, near to just above seasonal norms and about 5 to 7 degrees cooler than yesterday. Temperatures will rebound on Sunday with highs in the middle 80s to lower 90s as southwest winds increase in response to lee cyclogenesis across southeast Colorado which in turn is in response to height falls associated with approach of the next upper level short wave trough.
High pressure was over the Northland this morning, with cool, clear, dry conditions. A long-wave trough will move through the Northland Saturday. Highs will be in the lower to middle 60s. A few showers will linger into Saturday evening for eastern portions of northwest Wisconsin, as the low pressure system and upper level trough move off to the north and east. A quasi-zonal flow will then establish itself from Saturday night into Sunday, before the development of a major upper level ridge across the region during the early to mid part of the week.
358 AM EDT Sat Oct 7 2017 High pressure over the Mid Atlantic will gradually be pushed offshore this weekend as a cold front slowly advances from the Midwest.
316 AM CDT Sat Oct 7 2017 Widespread rain and a few embedded storms continue to track across the entire region this morning ahead of a cold front which is just now entering far northwest Missouri. Cold front will make steady eastward progress through the morning and will reach central MO some time around 10 or 11 AM.
Gusty winds will be the main forecast problem today as a strong upper level jet stream and passing cold front take aim for western Montana and central Idaho. While a brief lull will be possible over the next few hours, an increase and even strengthening of the winds is expected by mid day as the cold front passes. These are mainly expected over the higher terrain, though some showers could briefly reach over valley locations. Tonight into Sunday morning, forecast models indicate that precipitation will increase in coverage, particularly through central Idaho, as a disturbance rotates around the base of the upper level trough. With snow levels lowering to 3500-4000 feet, some accumulating snow will be possible for areas such as Dixie, Whitebird Grade, the Highway 12 corridor over Lolo Pass and Lost Trail Pass.
An area of low pressure over the Central Plains is drawing rain up into southern South Dakota this afternoon. The good mixing will lead to warmer temperatures with highs climbing well above normal and topping out in the mid to upper 70s. As temperatures rise, RH will tumble into the lower 20s across central SD.
During the rest of the day increasing westerly winds will help temperatures rise into the low 70s and upper 60s across the area this afternoon. Highest winds should be on the higher terrain of the Pembina escarpment, Devils Lake basin and Sheyenne basin.
Forecast lows in the lower 50s in the cooler valley locations continue to look on track. A progressive mid/upper level trough and an attendant surface cold front are over the middle of the CONUS. On Saturday and Saturday night an upper level ridge will build off the southeast coast as the upper trough presses in against it, and the tropical system makes landfall along the central Gulf Coast. Precipitable water values in excess of 2 inches along with surface dewpoint temperatures breaching the 70 degree plateau will allow for rainfall amounts of 1- 2 inches across much of eastern Kentucky through the day on Sunday as deep layer low pressure emerges out of the Gulf of Mexico into Dixie Alley.
Therefore have the highest PoPs in the east/southeast part of the area, but there should be a few across the area. A weak cold front will move through the area Sunday but temperatures will still be fairly seasonable.
345 AM MDT Sat Oct 7 2017 Windy conditions persist across much of the region today, especially in the higher terrain, but are expected to diminish Saturday night into Sunday. A surface cold front will bring cooler temperatures to much of the forecast area today and especially on Sunday.
the main high pressure ridge over the area is weakening and will continue to retreat over the next 24 to 36 hours allowing TS Nate to move northward across the central Gulf of Mexico.
1048 PM PDT Fri Oct 6 2017 A cold front will push across the region tonight. Much cooler weather will then persist through the weekend, with a chance of valley rain and mountain snow showers.
314 AM EDT Sat Oct 7 2017 Dry and warm weather is expected Saturday before rain chances return with a cold front Sunday. The warm front is lifting to our north, but a few warm advection sprinkles or light showers continue across central Ohio. Sunrise will bring a quick warm up as mixing increases in the warm sector ahead of tonight's cold front. A quick moving low pressure system will lift out of the Cornbelt, approaching the western Great Lakes by late this evening. The low will then move through the central Great Lakes before merging with the broader upper-level flow. As it does, it will sweep a cold front through the area overnight Saturday into Sunday morning. Will keep strong gusts in the high terrain overnight into Sunday morning.
Today Through Sunday Night A weakening cold front continues pushing toward the area this morning and will be one of two weather makers for this period. The parent trough is forecast to eject north of the area later today, so the best energy will remain north of the state. Drier and cooler air is noted behind this boundary but a significant change of air mass is not expected.
514 AM EDT Sat Oct 7 2017 Dry and warm weather is expected Saturday before rain chances return with a cold front Sunday. Sunrise will bring a quick warm up as mixing increases in the warm sector ahead of tonight's cold front. A quick moving low pressure system will lift out of the Cornbelt, approaching the western Great Lakes by late this evening. The low will then move through the central Great Lakes before merging with the broader upper-level flow. As it does, it will sweep a cold front through the area overnight Saturday into Sunday morning. Will keep strong gusts in the high terrain overnight into Sunday morning.

Big weather story today will be the approach and partial crossing of a cold front currently stretched NE to SW from the Central Plains to NM. High pressure continues over the area with a cold front stretching through the plains. Temperatures for the most part will be at or above normal values through the short term, with only northern/northwestern areas seeing slightly cooler temps in the wake of the cold front set to move through by Saturday.
Main story today will be gusty to strong west to northwest winds across the area as a cold front approaches from the north.
