As the high continues to build into the area today, we'll see notable weaker winds than yesterday. We'll see another night of efficient cooling tonight with weak winds and at least partly clear skies, dropping early morning lows back to near or below freezing once again.
An upper level northwesterly flow aloft and building high pressure at the surface will maintain dry conditions through the period. High pressure will slowly move east on Monday with a light west to southwest flow developing by the afternoon.
130 PM PDT Sun Mar 27 2022 High pressure will give way to an approaching low pressure system tonight through Monday night.
The long wave trough is lifting northeast across the North Atlantic, while an upper level ridge is building east across the Rockies.
251 PM MDT Sun Mar 27 2022 Expect a dry and warm night under ridge of high pressure. Upper ridge shifts slowly E on Monday, supporting a very warm and dry day with westerly mixdown winds from KBIL W. Northern portion of split trough will affect the area Monday night. It's worth noting that the deterministic GFS and ECMWF have come closer together in timing the cold front, but had large differences in precipitation timing.
332 PM CDT Sun Mar 27 2022 Northwest flow will persist aloft and at the surface has high pressure slides across the Ohio Valley and upper ridging builds eastward and into the Plains. Tonight will be cool once again, with overnight lows falling into the lower to mid 30s.

Highs will warm into the lower to mid 60s by the afternoon as winds continue to veer to the east.
(Tomorrow through Sunday) Winds will become southerly and increase Monday, allowing warmer temperatures to overspread the area by afternoon.
Behind a mid level trough and upslope surface winds out of the east to southeast, a slightly cooler afternoon in store Sunday with high temperatures in the upper 50s to mid 60s northeast to southwest across the CWA. A slight breezy expected in its wake seeing 10-20 mph diminishing some overnight becoming more southerly Monday as a leeside trough develops over eastern Colorado. Monday morning will see low temperatures a couple degrees cooler than Sunday with the aforementioned upslope cooling flow at the surface seeing low temperatures in the upper 20s to mid 30s hovering around the freezing mark for much of the CWA. With the return to southerly flow, expect warmer temperatures pushing afternoon highs Monday into 70s to mid 80s for deep southwest Kansas of Morton County.
Arthur Upper ridging prevails through tonight and into Monday, with dry and warm conditions expected. This should give a warm start to Monday, which remain under the the ridge axis through much of the day. A broad upper level trough will move into the region Monday evening, bringing precip across the region through the night. There is also a slight possibility for thunder with this system as the cold front moves into the region Monday night, but potential is limited.

Sky coverage will diminish and winds will lessen overnight as high pressure slides in from the west. As a low begins to develop across the Plains Tuesday, ridging will develop to the west and a warm frontal boundary will develop to the south.
helping to keep temperatures near freezing in all but the coolest spots. The main focus for the forecast continues to be the upper level area of low pressure off the central California coast. This low will be roughly in phase with a cold front approaching from the northwest Tuesday afternoon. with instability building across the local area ahead of the cold front.
A storm system will impact the area, bringing gusty winds today followed by a good chance of valley rain and mountain snow showers and much cooler temperatures on Tuesday.
Models show a massive high pressure cell expanding across the E CONUS, With an associated dry, decaying frontal boundary stalling around central Florida Today. Over the GOMEX, deep-layered ridging still dominates, and gradually Migrating east.
402 AM CDT Mon Mar 28 2022 A surface warm front will extend southward along the Colorado state line today and then eastward across northern Oklahoma, with most of central and southwestern Kansas on the cool side of the boundary with upslope southeast winds. This will prevent a huge warm up as highs should range from the mid to upper 60s at Hays to the lower 80s at Elkhart, with around 70 at Dodge City.
A fairly progressive weather pattern will continue through the week as a series of troughs and ridges traverse the area. Scattered shower activity expected today, followed by high pressure on Tuesday.
/28/ As the broad east coast upper trough finally pushes off into the northern Atlantic, upper ridging will move over our region. The upper ridge will remain in place through the entire short term forecast period, which will result in highs topping out in the upper 70s and lower 80s. Overnight lows will range from the lower to mid 50s in the northeast and east to the lower 60s in the west.
Tuesday morning a cold front originating in Alberta Canada will move across the Continental Divide and lower snow levels to around 3000 feet across northwest Montana and along the divide and to 4000 to 5000 feet across southwest Montana. Areas with the best potential for snow will be the higher in higher elevations of southwest Montana such as Georgetown Lake where an inch or two is possible. Any snow that occurs in the lower valleys will be brief and light with very little if any snow accumulations on grassy surfaces The weather pattern will remain active as several weather systems will pass through the region.
Today and Tonight: A mature low pressure system was located around 350 miles west of the Central Coast this morning, with an associated cold front moving onshore. Our focus for the remainder of today is on the approaching low pressure system and the potential for additional showers and isolated thunderstorms along with it. The low should make its approach this afternoon before landfalling along the Monterey/San Luis Obispo County line this evening. Showers will gradually end from west to east this evening as the low departs.
400 AM MDT Mon Mar 28 2022 One more day of near record temperatures is forecast as the strong ridge overhead begins to break down. This afternoon and evening, moisture begins moving into the southwest portion of Wyoming, denoting a pattern change as a robust trough moves through the western CONUS. The majority of the energy and lift with this wave is well to the south and associated with the cut-off, southern jet stream upper low; however, a northern stream open wave will drop down on Tuesday, creating enhanced lift and giving most locations east of the Divide an opportunity for precipitation.
A surface warm front will extend southward along the Colorado state line today and then eastward across northern Oklahoma, with most of central and southwestern Kansas on the cool side of the boundary with upslope southeast winds. This will prevent a huge warm up as highs should range from the mid to upper 60s at Hays to the lower 80s at Elkhart, with around 70 at Dodge City.
