318 PM MDT Mon Jun 10 2024 Current water vapor imagery is showing troughing over central MT with dry air building into our central zones behind a band of showers and thunderstorms. Tuesday, ridging and westerly flow wil build in, providing warm and dry conditions.
(Tonight) A cold front that moved southward across the area yesterday, now was located along the Gulf Coast. An area of high pressure with origins in Canada has moved SE-ward, and was centered over the western Great Lakes. It was bringing slightly cooler conditions to the Tennessee Valley. The region was under a NW flow aloft, thanks to rather deep troughing extending south and west from SE Canada, and upper ridging over the southern Great Plains.
The upper longwave trough down the Eastern Seaboard continues to dig through the Deep South and into the N Gulf pushing a surface frontal boundary and active weather into N FL shunting the Bermuda high well S into the S Bahamas. A plume of deep tropical moisture will be lifting up over the area overnight and Tuesday and align along a stalled frontal boundary in place across south Florida and a weak upper trough. The trough axis shifts west for the weekend, but enough moisture will remain to allow for scattered to numerous storms still.
Another inland trough developing on Tuesday will also move offshore Tuesday night, then high pressure will build across during mid week.
This activity has developed in the vicinity of a weak surface cold front. The frontal boundary and upper trough should be well to the west and south of the forecast area for Tuesday.

(Wednesday Night through next Tuesday) A strong four corners ridge of high pressure will start to push east late in the week into the weekend.
Taking a look across the area, lingering light showers continue to push eastwards ahead of a cold front roughly positioned along a Huron to Gregory line. As the cold front is quickly replaced by a mid-level ridge, the SPG will tighten leading to some marginally breezy conditions from the James River eastwards with gusts up to 25 mph possible by the afternoon hours. Otherwise, increasing warm air advection (WAA) and deep mixing with help temperatures increase slightly from the previous day with highs expected to peak in the low to upper 80s by this afternoon. Lastly, with increasing WAA advection expected overnight and light southerly winds, expect our overnight temperatures to stay a touch above normal with lows expected to be in the low to mid 60s.
Temperatures were mainly in the lower to middle 50s, though a few of the valley locations and typical radiational cooling spots were already into the upper 40s. High pressure will move across the region and provide mostly sunny skies to the area.
This lead to minimal changes in the high temperature forecast of roughly 1-3 degrees higher than previous forecast. Otherwise, dry northwest flow aloft and surface ridging will produce dry, clear, and warm days.
On the leeward side of this 591-594 dam heat dome and ridge axis, Deep South Texas and the Rio Grande Valley will be placed in a favorable location that again will yield near seasonable temperatures today and on Wednesday, while the core of the dangerous, searing heat grips parts of the western U. Rain chances will be little to none today courtesy of a weakening frontal boundary to our north-northeast, and high pressure influences and subsidence continuing over the region as mid to upper ridging strengthens.
A cold front will sweep through wrn and ncntl Nebraska Wednesday night.

A slight decrease in temperatures is expected later this week as low pressure passes to the south of the ridge, but temperatures will remain above average.
Surface analysis at 18z indicates the center of the low that brought us rain over southern Manitoba and Ontario. A relatively enhanced region of a stronger pressure gradient has developed on the backside of this low as a result, and is giving us sustained winds between 20-30 mph. Winds will diminish as this low continues to exit the region through the day today, so headlines are not likely (5% chance of Wind Advisory). Upper air flow towards late week shifts to northwesterly as an intensifying ridge sets in.
Warm and dry conditions will prevail through the end of the workweek as high pressure remains over the area.
No major changes to the short term as a weak upper level disturbance is set to flatten the ridge and provide a bit of a cool down for Wednesday. Overall high temperatures Wednesday will be about 5-7 degrees cooler than today, mainly for inland locations.
(Today) Weak upper low currently centered over the TX Panhandle will track southeastward today while gradually opening into a minor wave across E TX by Wed.
