Dew-points are forecast to climb into the lower 50s by late afternoon, which should help limit a more significant threat. South of I-40, precipitation chances will end from west to east this evening as upper low shift east.
Dry and cooler weather is anticipated Sunday under building high pressure. Have cancelled the high wind warning for all counties but eastern Tucker. Scattered rain showers should gradually taper off overnight with the passage of an upper trough. The precipitation should mix with or change to snow showers in cold advection, especially in the higher terrain areas. This should clear Sunday morning as high pressure begins to build across the Upper Ohio Valley region. Northwest flow and cold advection could lead to additional precipitation over the ridges Sunday morning. As drier air advances in from the north, any linger precipitation will end by late morning; a light coating of snow may occur in the higher elevations. Ridging will promote dry and seasonable weather Sunday afternoon.
1245 AM CDT Sun Apr 2 2023 (This evening through Monday) Upper low pressure continues to move through the eastern Great Lakes with another low over the Desert Southwest. By Sunday morning the upper low in the southwest will move east to New Mexico and open into a trough. The trough will move through Arkansas Sunday night and to the east coast by late Monday afternoon. As a warm front approaches from the south, chances of showers and thunderstorms will increase through the day but will be mainly in the afternoon and overnight Sunday. High pressure will build over the state Monday with dry weather.
317 AM EDT Sun Apr 2 2023 High pressure brings sunny, but cool and breezy conditions today.
Lastly, wrap around moisture behind an upper level Low will bring a chance of light snow over the northern half of the area throughout the day. Monday another trough moves in from the west bringing another storm system with it.
ARS Quiet weather will persist on Sunday as high pressure remains in place across the region. The weather pattern will become unsettled on Monday as a warm front lifts north across the region.
The wave to the north passes by and brings surface winds around to a more northerly direction which will bring slightly cooler readings.
The local forecast area will remain north of the sfc warm front however far SE OK may be near enough to sufficient elevated instability to warrant a window for isolated severe storms from late afternoon through early evening.
The rain and associated cloud cover will result in a return to warmer than normal morning lows again Monday.
822 AM EDT Sun Apr 2 2023 Dry and cooler weather is anticipated today under building high pressure. This will promote diminishing cloud cover and bring an end to any lingering snow showers over the highest ridges. Zonal flow aloft will keep a warm front parked right near the PA-NY border. Moisture will increase along the warm front Monday afternoon, and a late day shower cannot be completely ruled out over the northern reaches of the forecast area. With most of the area well into the warm sector on Monday, expect some sunshine and warmer temperatures.
649 AM EDT Sun Apr 2 2023 High pressure brings sunny, but cool and breezy conditions today.
658 AM EDT Sun Apr 2 2023 High pressure brings dry and tranquil conditions through tonight. Better chances for showers exist by mid week with a cold front. Generally into the upper 30s lowlands, ranging into the lower 30s northeast mountains.
549 AM CDT Sun Apr 2 2023 (Today through Monday) The boundary that has been parked just to our north will lift northward as a warm front today. As the warm front lifts north, warm air advection in its wake will lead to higher daytime temperatures for today and Monday. On Monday, expect highs to be even warmer, with some locations in the Brush Country and Rio Grande Plains approaching or even reaching the triple digits.
Current surface analysis places low over southern Saskatchewan, with trough/frontal boundary dropping to the south, while high remains over the Midwest. So far, any reports that we have had have been a little light rain as temperatures over much of our western areas remain above freezing. Where it starts getting tricky is as the precipitation moves east, surface temps will be below freezing, but warm air remains aloft. As the aforementioned low starts stacking up, some snow will linger over our far north where cooler air has wrapped in, diminishing some over the west and possibly lingering more around the Turtle Mountains. As we get later in the day into the evening, the far north gets onto the backside of the low with some additional snow wrapping in, reinforced by a secondary wave pulling in.
657 AM EDT Sun Apr 2 2023 High pressure will build across the region today, winds diminishing.

With strong ridging aloft building over the region, highs each day will be in the lower to mid 90s unless you are right at the coast.
(Rest of Today) A belt of westerly mid-level flow on the order of 45-55 knots will persist across the TN Valley today, with the region located north of a strong subtropical ridge centered over the southern Bay of Campeche. Scattered but thin cirrus clouds will spread across the region in this regime, but should not have a significant impact on afternoon temperatures that will range from the m-u 60s (NE) to the lower 70s (SW).
251 PM EDT Sun Apr 2 2023 Tonight will be cool once again, but temperatures trend warmer through midweek beginning Monday. Drier and cooler conditions return just before the weekend. High pressure shifts east of the region tonight, but dry conditions are expected through the daytime hours on Monday. Southwesterly flow will begin to advect warmer air into the region overnight, so the lows will occur fairly early, and then temps begin to warm up through the early morning hours Monday. Clouds begin to increase later in the afternoon as a cold front approaches. Shower chances increase Monday evening as the cold front drops in.
258 PM EDT Sun Apr 2 2023 High pressure slides eastward overnight. Better chances for showers exist by mid week with a cold front. Lingering CAA-induced stratocu continues to vacate the forecast area this afternoon in the midst of building high pressure. High pressure slides eastward overnight in preparation for a southern stream system encroaching from the west.
1230 PM EDT Sun Apr 2 2023 High pressure brings sunny, but cool and breezy conditions today.
Clouds are likely to stay around tomorrow even after the showers depart, so while tonight's lows will be considerably warmer than this morning's, tomorrow's highs won't be much higher than today's, despite the southerly winds tomorrow.
High pressure will keeps things dry this evening and tonight. Conditions should be favorable for a bit of a ridge valley temperature split tonight, with light winds and mostly clear skies on tap. Clouds will begin to increase towards dawn on Monday, but by then the temperature drop should be set, with most of our valleys bottoming at least several degrees cooler than the surrounding ridges. Overall we can expect valleys to drop to the upper 30s, with the surrounding ridges only making it into the low to mid 40s around the area. We should have a much warmer day on Monday, as winds shift back around to the south and increase to 7 to 10 mph during the day.
A return flow develops over the area today, with a warm front anticipated to lift northward across the forecast area tonight into Monday morning, bringing a return of abundant moisture to the region. The timing of the strong deep layer lift and the northward progression of the warm front will favor the best rainfall amounts over the northernmost counties late tonight into Monday morning, and with plenty of deep layer moisture in place have added mention of locally heavy rainfall in this portion. During the afternoon hours, daytime heating finally erodes the low level cap over interior areas, although the cap (a warm layer actually by the afternoon) may prove to be unusually stubborn over the southern portion of the area making it difficult for convection to get going. Highs on Monday will be mostly in the lower to mid 80s.
Overnight lows will be in the mid 60s over the interior to the low 70s along the coast. A little better chance of scattered showers and isolated thunderstorms during the afternoon hours, with the higher coverage over northern two thirds of the area.
For late this afternoon/evening forcing along the leading edge of the upper low could bring a more organized line of showers and possibly an embedded thunderstorm through the area.
914 AM PDT Sun Apr 2 2023 A trough of low pressure will be responsible for strong, gusty winds in the San Joaquin Valley and light precipitation in the Sierra Nevada and adjacent foothills tonight and Monday.
255 PM MDT Sun Apr 2 2023 AFTERNOON UPDATE: Winds are just beginning to diminish west of Fort Peck Lake, so kept the High Wind Warning going to make sure and for continuity with Garfield county still gusting over 50 mph, but fully expect it to expire by 6pm.
Highs on Monday will be well above seasonal normals, in the low tom id 90s for most locations.
Showers will strengthen and become a little more organized during the late afternoon and evening hours as a mid level low pressure rapidly develops and closes off across central Idaho. However much like our closed low system a few days ago there will be areas that receive locally higher amounts upwards of 7 inches. The broad low pressure trough will maintain its grip over the region through much of this week.
A weak cold front analyzed on the 20z/3pm surface chart extending from Minnesota southwestward to Nebraska will drop into central Illinois tonight.

932 AM MDT Sun Apr 2 2023 MORNING UPDATE: The Winter Weather Advisory was allowed to expire just after 9am this morning, due to winds drying most of the rain from last night and road temperatures rising above the freezing mark. Lastly, wrap around moisture behind an upper level Low will bring a chance of light snow over the northern half of the area throughout the day. Monday another trough moves in from the west bringing another storm system with it.
1256 PM EDT Sun Apr 2 2023 Dry and cooler weather is anticipated today under building high pressure. Zonal flow aloft will keep a warm front parked right near the PA-NY border. Moisture will increase along the warm front Monday afternoon, and a late day shower cannot be completely ruled out over the northern reaches of the forecast area. With most of the area well into the warm sector on Monday, expect some sunshine and warmer temperatures.
(north of a Brenham to Liberty line) with the highest POPs for the trifecta of Houston, Trinity and Polk counties. Not many changes to this ongoing warm/humid weather is expected tomorrow as a flat almost zonal ridge prevails at the mid/upper levels and a steady S/SE flow at the surface. No POPs so slightly more sun will lead to warmer highs for Mon (in the mid to upper 80s). Lows tomorrow night will be in the lower 70s once again.
Progressive pattern will take post frontal ridge east to the western Atlantic by this evening.
Clear and quiet tonight, as weak low pressure treks across SW KS, providing a variable wind direction, trending toward light northerly through sunrise Monday. Most locations will remain above freezing through tonight. The exception to this will be far southwest Kansas, where strong southwest winds are expected by late afternoon, southeast of the SE Colorado cyclone. This boundary will provide no sensible weather elements, only delineating slightly cooler air and more easterly wind components north of the front.

High to mid-level clouds will move in as well and still expecting a weak cold front to push through over night with a passing low to the north. Wagner (Issued 351 AM CDT Sun Apr 2 2023) Today through Monday: Dry weather is expected today into tonight as high pressure overhead this morning departs to the east. Southerly winds will pick up later this morning into the afternoon on the back side of the high and ahead of an approach trough. It will be cooler near the lake, with an onshore component to the southerly winds likely.
1218 PM CDT Sun Apr 2 2023 (Today through Monday) The boundary that has been parked just to our north will lift northward as a warm front today. As the warm front lifts north, warm air advection in its wake will lead to higher daytime temperatures for today and Monday. On Monday, expect highs to be even warmer, with some locations in the Brush Country and Rio Grande Plains approaching or even reaching the triple digits.
237 PM EDT Sun Apr 2 2023 High pressure will build overhead today, then push offshore tonight. A southwest flow and building high pressure aloft will bring a warmup through mid week.

833 PM MDT Sun Apr 2 2023 Latest satellite imagery shows upper low spinning off the Pac NW coast tonight helping to usher in evening convection through the area. The flow within this low showing a buckling across central Oregon. This buckling of the flow should help push a cold front through the region later this evening bringing a brief period of heavier rain/snow/graupel to the region as it passes through the area as 00z Boise upper air sounding does show some instability this evening. Showers should diminish after midnight, only to start up again Monday as the upper low remains over the region.
A cold front continues to press southeastward through IA this evening approaching the Mississippi River as of 830 PM. A weak cold front analyzed on the 20z/3pm surface chart extending from Minnesota southwestward to Nebraska will drop into central Illinois tonight.

739 PM EDT Sun Apr 2 2023 High pressure and drier air will remain over the region tonight with an upper level disturbance moving into the region Monday morning with chances of showers and a few thunderstorms.
East/West oriented subtropical ridge will hold over the Gulf of Mexico with the ridge axis across the southern Gulf. on Monday with high cloudiness advecting over the Florida peninsula riding over the subtropical ridge. Big story for the upcoming week will be the strong U/L subtropical ridge which will build over the Florida peninsula with a significant increase in 50H heights and strong large scale subsidence developing over the forecast area.
A cold upper trough with 700 mb temperatures at or below -17C was advancing east across coastal OR/WA this afternoon. Cooling midlevel temperatures were aiding in steepening lapse rates and lowering snow levels, with small hail evident in radar imagery near the Humboldt/Del Norte coast, transitioning to snow showers across inland ridges. After Monday morning, the previously mentioned trough is forecast to exit east and amplify across the Great Basin. However, steep lapse rates will still exist in the wake of the trough, particularly during peak afternoon heating, which will favor diurnally driven showers across the inland ridges and mountains.
A warm front extends from southern Oklahoma eastward into southern Arkansas. As the warm front moves north overnight, showers and a few thunderstorms will increase in coverage across the Mid-South.
-Stoinskers Previous Discussion: Winds are just beginning to diminish west of Fort Peck Lake, so kept the High Wind Warning going to make sure and for continuity with Garfield county still gusting over 50 mph, but fully expect it to expire by 6pm.
222 AM EDT Mon Apr 3 2023 A warm front enters the middle Ohio Valley and a southern stream system passes to the south today. A stronger system brings showers and storms with a mid week cold front. A few showers may begin moving into southeast Ohio as the warm front enters the Ohio Valley this morning. After a brisk morning, southerly flow will bring much warmer air up into the area today. This should result in afternoon highs in the upper 60s to low 70s across much of the area, and mid 50s in the higher elevations of the northeast mountains.
(Today) Unseasonably warm conditions expected today with highs in the lower to mid 80s across most of E OK/NW AR.
