201 PM CDT Sat Jun 25 2022 Isolated showers and thundershowers have developed from eastern to southern MN along a cold front early this afternoon. This activity should remain weak as the cold front pushes east through MN. After the cold frontal passage, skies will mostly clear while surface winds prevail west- northwesterly. The flow will usher in much drier and cooler air to begin our upcoming week.
Ridge building from the west will bring dry weather tonight thru Sunday night. Given clear skies, light winds and high pressure overhead, tonight will be another chilly night with upper 30s to mid 40s for lows.
238 PM EDT Sat Jun 25 2022 A few light sprinkles or showers for the western half of the CWA this afternoon before a weak cold front brings a chance for a few more rain showers and perhaps a few embedded thunderstorms overnight.
1133 AM CDT Sat Jun 25 2022 Updated aviation section for 18z taf issuance High pressure will move east of the area today, allowing for modest return flow.
With the upper trough swinging through, temperatures will remain moderate Sunday with highs only in the 70s.
243 PM EDT Sat Jun 25 2022 High pressure centered off the Mid Atlantic coast will provide a dry weekend with seasonably warm temperatures.
However, will keep it as just showers for now, due to the low likelihood of much thunder. Sunday highs should be a little warmer to the west of the Red River Valley, and a little cooler to the east, where there will be more clouds.
258 PM CDT Sat Jun 25 2022 Cold front has traversed east across the forecast area today (located just east of Storm Lake, IA as of 2 PM CDT/19z). Mostly clear skies continue tonight, and with a secondary push of CAA as upper low swings across southern Canada, expect temperatures to remain on the cooler side. Expect lows in the lower to mid 50s. Cooler for Sunday with northwesterly flow and CAA in place aloft. Again, did drop highs a degree or two from the previous forecast, in the low to upper 70s. Gusts tomorrow could reach 30 mph, but should taper off during the late evening as mixing decreases and high pressure builds in.
A cold front is working its way southeast through our area right now, currently stretched from the north side of KC over to Unionville, MO. This front is helping areas along and north of it stay on the cooler side, although it likely still feels soupy. Tomorrow, high pressure, cooler temperatures, and slightly drier dew points move in making for a rather nice June day.

/TW/ The synoptic pattern remains unchanged with stout upper ridging centered over the Lower Mississippi Valley. A pocket of dry air across eastern Mississippi will keep heat indices there in check as dewpoints mix out into the low 60s to upper 50s. This will lead to warmer than normal temperatures through the period.
1240 PM CDT Sat Jun 25 2022 KEY MESSAGES: - Showers/thunderstorms this morning will diminish this afternoon with the passage of a cold front.
The subtle increase in ridge amplification noticed at 500 mb over MI, decreasing PWAT by around a quarter of an inch, and the dry resident airmass with around 20-30 degree F dewpoint depression or higher was not a favorable environment for maintenance of the northern end of this system into the forecast area. The greater 850-500 theta-e plume and higher PWAT values ahead of the cold front will bring better chances for precipitation early this evening and tonight. Westerly winds develop by late morning into the early afternoon as drier air and cooler temperatures begin pushing into southeast Michigan. The coldest post frontal air does not arrive until Sunday night, so afternoon highs for Sunday will only be slightly cooler compared to today in low to mid 80s.

1028 AM PDT Sat Jun 25 2022 High pressure returns overnight into Saturday, starting a gradual warming trend.
Although some partial clearing has occurred in the Wrn half of WI, this has allowed for some instability to fill in and SHRAs to develop along and out ahead of an approaching cold frontal boundary. will probably largely remain dry into early this evening as the higher PWATs/moisture content is displaced and streaming into the W half. There could be a few very light rain showers Sunday afternoon as the trough axis pushes eastward with the mid-level low exiting Ontario into western Quebec.
303 PM CDT Sat Jun 25 2022 Tonight and tomorrow: Pesky upper ridging that has been parked over the Lower Mississippi Valley will finally begin to break down and retrograde into the Southern Plains. This will occur as a potent northern stream trough slides across the Northern Plains into the Great Lakes region. At the surface, a cold front will be dropping out of the Central Plains and is forecast to be draped across northern Arkansas into the Ohio River Valley. This will result in mild overnight temperatures with lows only falling into the low to mid 70s.
1221 PM EDT Sat Jun 25 2022 High pressure maintains dry weather today. The next cold front crosses Sunday night, with showers and thunderstorms Sunday afternoon and night.

H5 geopotential heights of 588 dam expand marginally into southern Lower Michigan today denoting minor ridge amplification while the focus of the anticyclone fixates over Arkansas. The potent moisture plume advecting eastward marked by sharp 0-3 km AGL layer max ThetaE gradient reveals that most of the lower tropospheric moisture gets displaced well ahead of an inbound cold front. Rest of Sunday looks to be a bit cooler (mid 80s) with healthy zonal gusts around 25 mph at times.
130 PM EDT Sat Jun 25 2022 High pressure centered off the Mid Atlantic coast will provide a dry weekend with seasonably warm temperatures.
Temperatures are generally running 1 to 2 degrees warmer than they were at this time yesterday. A few thunderstorms may also approach northeast Oklahoma late this afternoon as a cold front moves into southeast Kansas.
0-6km steering flow will be much lighter today, which should result in slow (outflow-oriented) storm motion with a preference for convective initiation and maintenance over the higher terrain. The ridge remains in control over the southwest for much of the upcoming week. Heights do begin to gradually decrease, however as the ridge begins to wobble eastward.
309 PM EDT Sat Jun 25 2022 High pressure moves off the coast tonight.
1226 PM EDT Sat Jun 25 2022 Weak high pressure overhead will slide east and start to direct warmer air in from the south this afternoon and Sunday.
Most of the remainder of the Midsouth was in the middle 90s with heat indices only a degree or two warmer. A refreshing change is coming tomorrow as a cold front moves across the Midsouth. It will still be a hot day tomorrow, especially across north Mississippi where showers will arrive latest, but clouds should help keep us in the low to middle 90s.
