Temperatures will trend warmer for the next several days. High pressure will be over the region today bringing dry weather and below normal temperatures as highs will be in the upper 50s to mid 60s. A warm front will into the region on Wednesday with showers and thunderstorms moving across the Mid-South. Temperatures will be a little warm with highs in the lower 60s to lower 70s. A cold front will approach the region Wednesday night with more showers and thunderstorms moving through the Mid-South.
High pressure currently centered across the mid Mississippi valley will build eastward and strengthen across the Tennessee valley tonight. Meanwhile, a dirty ridge will begin to build eastward across the GOMEX. Under the influence of high pressure conditions will remain quiet through tonight. Temperatures will cool efficiently tonight under clear skies with lows falling to the low 40s inland across GA and Suwannee Valley while warmer lows in the mid upper 40s are expected across the rest of inland NE FL.
338 PM CDT Tue Apr 19 2022 /Updated at 0101 PM CDT Tue Apr 19 2022/ High pressure will move across the southeast today with mostly clear skies. Tonight, as the high pressure moves towards the east coast, low and mid level winds will transition to out of the east. As the southeasterly winds bring moisture and warmer air. Low levels remain dominated by ridging and characterized by drier air. Upper level ridging will build across the area, keeping conditions dry but warm through the weekend.
243 PM CDT Tue Apr 19 2022 Increasing cloud cover and strengthening southeast winds tonight will help temperatures remain steady in the lower to mid 40s overnight. A warm front will lift across central Illinois Wednesday bringing showers and a few storms to the area.
The ridge will slide across the area during the next several hours, setting up some return flow and much warmer temperatures tomorrow.
--BMickelson Previous discussion: Windy conditions are expected for the area over the next few days as a stacked low pressure system moves across the Canadian prairies. East winds this morning will turn west this afternoon as a warm front associated with the low tracks eastward across the state. Overnight a cold front drops out of Canada, with winds turning northwest on Wednesday afternoon. There is some potential for freezing rain as temperatures drop, but for now just kept rain and snow in the forecast. Warm front will lift across the region today with winds turning from east to west through the day.
258 PM CDT Tue Apr 19 2022 Southeast winds continue to gust ahead of the approaching low pressure system. No major changes in thinking around the effects of this low. High pressure builds in Wednesday night and winds diminish from west to east.
Early afternoon temperatures range from the middle 50s to low 60s across the area with afternoon highs expected to be in the low to middle 60s. Weak ridging will shift over east Tennessee overnight and a weak trough will shift out of the Plains, over the Mississippi River Valley tomorrow. A warm front will lift north across the Midsouth during the day. A weak cold front is expected to stall somewhere over northeast Arkansas, northwest Tennessee or south Missouri Wednesday night.
Highs on Wednesday well up into the mid 90s, perhaps upper 90s, with conditions a little cooler farther east.
There will be a trough in the northern Rockies and one over the lower Great Lakes 00z Wed. The western trough moves into the northern plains 12z Wed and into the upper Great Lakes 00z Thu with the trough axis passing across the area on Thu. In the extended, GFS and ECMWF show a deep 500 mb trough in the western U. This trough then heads northeast into the northern plains 12z Sun and into the upper Great Lakes region 12z Mon into 12z Tue. VFR will then remain the predominant flight category at all TAF sites through the end of the TAF period as high pressure strengthens over the region. North winds will be up to 30 knots this morning before high pressure builds in from the west and diminishes the wind.
Temperatures are quickly warming well above freezing across much of the forecast area, so canned the Freeze Warning and Frost Advisory early. Not planning to touch the ongoing freeze warning and frost advisory since there may be a small window towards daybreak where temperatures may dip near freezing, especially for counties under the freeze warning. Low temperatures tonight will be warmer thanks to the clouds, falling into the lower to middle 40s. PoPs will increase from west to east during the day Wednesday, as the trailing cold front begins to move into the region. Temperatures will not fall much on Wednesday night, however, with values only dropping into the lower 50s.
217 PM CDT Tue Apr 19 2022 High pressure will slide to the east tonight.
Lows tonight will be mild, ranging from the lower 50s across southern Arkansas to the lower 60s across East Texas. Highs Wednesday will be warm, ranging from the mid 70s to the lower 80s. /Wednesday Night and Beyond/ The warm and humid conditions continue to end the week, as an amplifying and deepening longwave trough over the West CONUS allows for upper ridging over the tri-state area.
Issued by National Weather Service Duluth MN 348 PM CDT Tue Apr 19 2022 Summary: High pressure is departing the area today with cloudy conditions entering from the west. A low pressure system will make its way towards western MN tomorrow morning with rain spreading across the region.
312 PM CDT Tue Apr 19 2022 Through Wednesday: High pressure will begin to shift east of the forecast area during the near term, and this will result in a tightening pressure gradient and increasing southerly wind as we go through the day Wednesday.
Winds will slightly diminish, lose the higher end gustiness, overnight.
Storm chances may continue overnight as isentropic ascent strengthens with the low level jet.
329 PM EDT Tue Apr 19 2022 Canadian high pressure will slowly build into the region from the west through tonight. The high will move eastward through central NC Wednesday, shifting offshore Wednesday night. The pressure gradient will relaxing later this evening as the high begins to build into the area. The calm/light winds and clear skies should result in excellent radiational cooling across central NC with lows generally in the low to mid 30s expected. Some of the usual cooler spots across central NC could dip into the 30-32 degree range so take the necessary precautions to protect sensitive vegetation. Temperatures will dip into the low to middle 40s with upper 30s in the typical colder spots.

From roughly 10 pm through 5 am CDT, this moist/saturated layer will move from southwest to northeast across the WFO PAH forecast area, producing very light QPF across the area, coincident with a minor vorticity lobe moving along the departing low-mid level ridge axis to the east. High pressure will slide to the east tonight.
917 PM EDT Tue Apr 19 2022 Isolated snow and rain showers will end this evening as high pressure begins to build in.
A stronger weather system will move through the region by the end of the week bringing much cooler temperatures that will be below normal with readings mostly in the 80s as well as windy conditions. DISCUSSIONâ¦ Zonal flow predominates across the Desert Southwest between an anticyclone south of the Baja Peninsula and a double-barreled area of low pressure across the Pacific Northwest. In the wake of the aforementioned low pressure system, temperatures will drop a few degrees Wednesday but remain above normal. The pattern will then amplify across the western CONUS as a low pressure system approaches the west coast.
611 PM CDT Tue Apr 19 2022 High pressure will slide to the east tonight.
1022 PM EDT Tue Apr 19 2022 Low pressure tracks through eastern Canada tonight as high pressure builds to the southwest of the area. The high builds over the northeast Wednesday, remaining into Wednesday night.

800 PM EDT Tue Apr 19 2022 High pressure over the Tennessee Valley continues to build over west central and southwest Florida with drier air advecting across the region under clear skies. The area of high pressure will slide off the mid Atlantic coast on Wednesday with boundary layer winds across the peninsula veering to the east and northeast.
Cold front moving into central Wyoming this afternoon.
600 PM EDT Tue Apr 19 2022 Scattered snow and rain showers will continue this evening before high pressure builds in overnight.
The break in the weather will be short-lived, as another, more potent upper trough digs over the E Pacific late tonight and Wednesday.

/DL/ Prior discussion below: Through Wednesday: High pressure will begin to shift east of the forecast area during the near term, and this will result in a tightening pressure gradient and increasing southerly wind as we go through the day Wednesday.
941 PM CDT Tue Apr 19 2022 Another night of tranquil weather ahead as an upper ridge axis centers over the area. This will start a string of warm and "mostly dry" days as a persistent surface and 8h ridge parks over the Carolinas into AL. This occurs as a low level jet across the lower MS valley veers to the southwest while a decaying MCS basically falls apart across the lower TN valley.
722 PM CDT Tue Apr 19 2022 VFR conditions will prevail across the terminals tonight as high pressure shifts east of the area. A low pressure system pushing across the Central Plains will lift a warm front into the area early on Wednesday. Lows tonight will be mild, ranging from the lower 50s across southern Arkansas to the lower 60s across East Texas. Highs Wednesday will be warm, ranging from the mid 70s to the lower 80s. Moist air will remain in place in the low levels of the atmosphere resulting in a mostly cloudy and warm night with lows mainly in the 60s.
616 PM EDT Tue Apr 19 2022 High pressure building into the Ohio Valley by this evening.
654 PM CDT Tue Apr 19 2022 Summary: High pressure is departing the area today with cloudy conditions entering from the west. A low pressure system will make its way towards western MN tomorrow morning with rain spreading across the region.
928 PM EDT Tue Apr 19 2022 Low pressure will lift off to the north overnight, allowing high pressure to build in from the west into tomorrow.
A stronger weather system will move through the region by the end of the week bringing much cooler temperatures that will be below normal with readings mostly in the 80s as well as windy conditions. Zonal flow predominates across the Desert Southwest between an anticyclone south of the Baja Peninsula and a double-barreled area of low pressure across the Pacific Northwest.

The pattern will then amplify across the western CONUS as a low pressure system approaches the west coast.
922 PM CDT Tue Apr 19 2022 High pressure remains over the Mid-South this evening. The high will begin to shift east overnight allowing for southeasterly winds to begin to increase as cirrus spreads into the region. Early afternoon temperatures range from the middle 50s to low 60s across the area with afternoon highs expected to be in the low to middle 60s. Weak ridging will shift over east Tennessee overnight and a weak trough will shift out of the Plains, over the Mississippi River Valley tomorrow. A warm front will lift north across the Midsouth during the day. A weak cold front is expected to stall somewhere over northeast Arkansas, northwest Tennessee or south Missouri Wednesday night.
Otherwise, mostly clear skies are expected with cool readings, mainly in the lower to middle 40s, except for some upper 30s in the northeast. 08 Previous short-term discussion: /Updated at 101 PM CDT Tue Apr 19 2022/ High pressure will move across the southeast today with mostly clear skies. Tonight, as the high pressure moves towards the east coast, low and mid level winds will transition to out of the east. As the southeasterly winds bring moisture and warmer air. Low levels remain dominated by ridging and characterized by drier air. Upper level ridging will build across the area, keeping conditions dry but warm through the weekend.
/DL/ Through Wednesday: High pressure will begin to shift east of the forecast area during the near term, and this will result in a tightening pressure gradient and increasing southerly wind as we go through the day Wednesday.
651 PM CDT Tue Apr 19 2022 High pressure has moved off to the east of Arkansas and is bringing a southeast wind to the state. A warm front will move into south Arkansas by the end of the period.
531 PM MDT Tue Apr 19 2022 Fairly active flow pattern will persist in the period as a deep upper trough digs into the western CONUS and eventually supports another deep sfc cyclone in the Northern Plains this weekend. Very dry BL will support a dry fropa, with the best chance for precip arriving late tonight as the main upper trough advects into the FA. Best chance for precip will be over the higher terrain of NE WY and the northern BH, with sct activity elsewhere. Secondary impulse will support another weak trough through the region Wed.
A dry warm front is moving through northeast Montana today resulting in a few sprinkles, if anything at all. Warmer temperatures are pushing into the area on the wings of westerly winds up to 35. The weak, western state upper level low pressure trough initially seems broad and disorganized as it approaches the the continental divide.
A broad northwest flow aloft was in place this afternoon with a 5h ridge axis exiting the Plains. This will start a string of warm and "mostly dry" days as a persistent surface and 8h ridge parks over the Carolinas into AL. This occurs as a low level jet across the lower MS valley veers to the southwest while a decaying MCS basically falls apart across the lower TN valley.
The higher thunder potential should remain focused to the south, across southeast OK into northwest AR. By late afternoon, a dryline will advance east into central Oklahoma while a cold front sags south to near the Kansas/Oklahoma border. Isolated strong to severe thunderstorms may develop along the dryline to the west, but the more likely scenario is for a few strong to severe storms to form along the advancing cold front as sunset approaches Wednesday, with these storms affecting mainly northeast Oklahoma and possibly northwest Arkansas Wednesday evening before weakening overnight.
Showers and thunderstorms will begin to ramp up in coverage in our west after 12z today ahead of an approaching surface cold front. Tonight, the cold front will elongate west to east across the forecast area. On Thursday, the surface boundary will retreat to the north as a warm front in response to increasing H5 heights over the southeast CONUS. High temperatures will reach the lower 70s, but dew point temperatures will also climb into the upper 50s to lower 60s.
Southerly winds will pick up today as high pressure moves off to the east.
By this afternoon and into the early evening, a 50-60kt LLJ ahead of the cold front will be over the Mississippi River, pulling a greater fetch of Gulf moisture into the region. Onset of precip may be delayed a few hours due to a decent dry layer in the lowest 3km, but eventually the lowest levels will become saturated enough to support precip reaching the sfc by late tonight. Meanwhile, upper level ridging will begin building in from the west, and will continue to strengthen/amplify over our region going into the weekend.
1105 PM CDT Tue Apr 19 2022 Summary: High pressure is departing the area today with cloudy conditions entering from the west. A low pressure system will make its way towards western MN tomorrow morning with rain spreading across the region.
357 AM EDT Wed Apr 20 2022 High pressure will bring a dry day with increased sunshine and moderating temperatures. Rain chances return late tonight and Thursday with a passing trough.
There is a least a minimal chance for thunderstorm development late in the day Thursday despite a less than robust west-southwesterly flow aloft well downstream of an upper level trough in the beginning stages of moving ashore into central/southern California.
Clear skies start off this morning but an approaching low pressure system to our west in the Plains will filter in mid-level clouds starting mid-morning. By this evening a 50-60 knot low level jet will take aim at lower Michigan allowing for increased moisture advection while a mid-level trough approaches. Lingering light rain may persist until 8-10am until the low passes east and surface ridging moves in place.
344 AM CDT Wed Apr 20 2022 Tranquil weather on-going across the Tennessee valley this morning, with high pressure still promoting mostly clear conditions. These mid/high clouds may become denser by the mid/late afternoon, but southerly flow and earlier sunshine will easily counteract this and subsequently expect high temperatures to return to the lower 70s. Subsidence from the ridge will help to keep things dry across our area once again, though we'll have to watch for the possibility of a few elevated showers in far northwest Alabama that will form along a stalled boundary to our northwest. High pressure will remain the dominant weather feature across the region late this work week, promoting warmer and mainly dry conditions. Thereafter, the aforementioned ridge to the east of the area will win out and begin to amplify.
128 AM EDT Wed Apr 20 2022 High pressure will be in place overnight.
Another night of tranquil weather ahead as an upper ridge axis centers over the area. This will start a string of warm and "mostly dry" days as a persistent surface and 8h ridge parks over the Carolinas into AL. This occurs as a low level jet across the lower MS valley veers to the southwest while a decaying MCS basically falls apart across the lower TN valley. A surface cold front stalls out across KY and southern MO late Wednesday night into Thursday morning. On Thursday, less clouds and slight warm air advection will lend to warmer highs in the upper 70s to around 80. A 500 mb anticyclone intensifies over the southeast U.
From roughly 10 pm through 5 am CDT, this moist/saturated layer will move from southwest to northeast across the WFO PAH forecast area, producing very light QPF across the area, coincident with a minor vorticity lobe moving along the departing low-mid level ridge axis to the east. High pressure will slide to the east tonight. As ridging sets up at 500H, this will keep the cold front to our north and eventually into the upper Midwest.
The higher thunder potential should remain focused to the south, across southeast OK into northwest AR.
Cold front moving into central Wyoming this afternoon. Cooler temperatures Wednesday with these colder 700mb temperatures.
Discussion: A mid level cloud deck has moved over the region this afternoon with even a few echoes showing up on radar, but so far rain is struggling to reach the surface due to evaporation as the low levels remain quite dry. However, low level moisture will continue to gradually increase through the rest of today and tonight, with stratus and warm/moist advection keeping overnight lows in the mid to upper 40s tonight compared to the near/below freezing temperatures of this morning.
1256 AM EDT Wed Apr 20 2022 High pressure will bring a dry day with increased sunshine and moderating temperatures. Rain chances return late tonight and Thursday with a passing trough.
245 AM EDT Wed Apr 20 2022 Canadian high pressure over eastern North Carolina and Virginia will shift offshore this evening.
20/06Z TAF CYCLE High pressure has moved east of the area and southerly flow has returned. Showers and thunderstorms are expected Wednesday as a warm front approaches. Today Through Thursday High temps this afternoon are reaching the lower 60s to the lower 70s across the CWA. Upper level cloud cover is entering the state from the west as high pressure shifts eastward out of the state. A warm front will lift NNE across TX, OK, and AR Wed.
Currently, a warm front extended from east Texas across southwest Oklahoma and into southwest Kansas. This warm front will move east reaching western Arkansas by late this afternoon. Scattered showers and a few thunderstorms are expected to develop ahead of the warm front with some of this activity reaching mainly western sections of the Mid-South especially during the afternoon hours.
330 AM EDT Wed Apr 20 2022 Canadian high pressure over eastern North Carolina and Virginia will shift offshore this evening.
1033 PM MDT Tue Apr 19 2022 Fairly active flow pattern will persist in the period as a deep upper trough digs into the western CONUS and eventually supports another deep sfc cyclone in the Northern Plains this weekend. Very dry BL will support a dry fropa, with the best chance for precip arriving late tonight as the main upper trough advects into the FA. Best chance for precip will be over the higher terrain of NE WY and the northern BH, with sct activity elsewhere. Secondary impulse will support another weak trough through the region Wed.
1200 AM EDT Wed Apr 20 2022 High pressure will build in from the west today. High pressure will shift offshore tonight into Thursday allowing low pressure to track off to our northwest.
409 AM EDT Wed Apr 20 2022 High pressure over the Mid-Atlantic region favors fair dry weather. High pressure is centered overhead this morning. As the high moves east, expect the development of a light southerly wind. Temperatures tonight are expected to remain above freezing. Based off the latest sweep of CAMS, slight chance to chance POPs were pressed further east: it looks like showers should be able to make it up to the Blue Ridge, with a few spilling over before the front dries up. Following the front Thursday, high pressure re-settles over the area with a strong ridge developing over the eastern U.
343 AM EDT Wed Apr 20 2022 We have another chilly morning under some strong radiational cooling, though temps should stay mainly above freezing and only some patchy frost potential in the far NE. Dewpts should be a bit higher along with some temps moderating warmer today and resultant min RH values look to stay above fire danger levels today. Thursday max temps are progged to moderate even warmer with many areas above climo reaching the upper 70s to low 80s.
