Water vapor imagery highlights a long wave trough over the Eastern US and southern stream short wave pressing through Texas. The last frames of IR/VIS satellite imagery noted a lengthy trough axis bisecting south-central Florida which extends to the Yucatan. Along this trough, a potent MCV moved onshore near Tampa this evening. The moist conveyer remains intact, and coupled with the low-level ridging making a comeback, we should see the convergence zone setup camp once again in the southeastern Gulf. The pattern this week will feature weak high pressure over the western North Atlantic and a frontal boundary stalled over northern Florida.
As the center of the low approaches the area, CAMs support an increase in showers late tonight from south to north. Will need to watch any convection near the center of the low for enhanced rainfall amounts, which have already been observed along the coast of Sarasota and Manatee Counties this afternoon and evening. Morning lows are forecast in the lower to mid 70s.
Another round of showers and thunderstorms will arrive this weekend as another weather system moves through the area bringing cooler and windier weather. When looking at the potential for high wind, a stray gust above 60 mph cannot be ruled out along the lower elevations of the Rocky Mountain Front. But the probabilities of widespread impacts for both the lower and higher criteria zones makes it difficult to justify going with a high wind warning at this point in time.
Smoke is not expected to be an issue across southern Idaho at this time due to an upper-level low moving across southern Alberta, Canada, accompanied by a dry cold front that has already reached parts of southeast Oregon. The highest winds tonight will be between Baker Valley and the Lower Treasure Valley. The passage of the front overnight will result in temperatures about 5 degrees cooler on Wednesday.

Expect this to occur in southern middle Tennessee, as a weak trough axis at the surface moves southeast this evening. As this trough axis shifts further southeast, it should re-enforce very weak advection of slightly drier air into the area as it does so. Temperatures have already dropped into the lower to mid 60s in many locations.

The high coverage of showers (embedded thunder - esp this aftn) continues today. As the center of the low approaches the area, CAMs support an increase in showers late tonight from south to north. Will need to watch any convection near the center of the low for enhanced rainfall amounts, which have already been observed along the coast of Sarasota and Manatee Counties this afternoon and evening. Morning lows are forecast in the lower to mid 70s.
Temperatures are warming to an average 5 to 15 degrees warmer than normal east of the Cascades this afternoon with highs in the 80s. Ridging will still be in control through Thursday.
Mixing and dry top soil to temporarily keep sfc DPTs from climbing much out of the lower 60s until later tonight. Ridge-riding westerlies with embedded short wave aloft to make today's unsettled convective region be the eastern Dakotas into MN, with some of this activity bleeding down acrs the MN/IA border region this afternoon. Still some capping to overcome, but the higher sfc DPTs, forcing of the front squeezing southeastward, and digging short wave aloft could allow for strong developing convection overhead and along/north of the current day 2 Slight Risk.
(Today through Thursday afternoon) With the upper trough well to the east and any surface fronts washing out, a quieter pattern settles in.

(Today through Thursday) Key Messages: - Tropical funnel clouds remain possible today - Low to medium (20-40%) chance of showers and thunderstorms today, decreasing to a low (20%) chance on Thursday A mid to upper level trough extending from our northeast will produce local bands of positive vorticity advection and in combination of PWATs near 2. Subsidence develops aloft tonight as the trough shifts southeast and an upper ridge extends into Texas from Mexico, causing northeasterly to northwesterly flow aloft.
(Today through Thursday) An upper level weakness within broad ridging will slide across the Lower Mississippi River Valley today and over the northern Gulf Coast tomorrow.
The upper trof driving the front is moving across the northern plains, where most of the better lift for storms remains. Wednesday into Thursday the upper pattern flattens as the upper low off the west coast shifts increasing heights and ridging overhead.
325 AM EDT Wed Jun 12 2024 High pressure will slowly build into the region today clearing out the stubborn clouds.
While cloudier conditions will keep temperatures in the mid 80s for one more day, locations that see clearer conditions than currently forecast will likely see temps closer to the high 80s.
Easterly/offshore flow continue at this time, due to a strong ridge of high pressure over the Southwest and Great Basin with an upper-level low off the coast of Southern California, based on latest satellite imagery. Today's highs remain on track to reach triple digits across much of the lower elevations, where the Heat Advisory remains in effect.

In depth discussion: An upper level trough at 500 mb with good baroclinicity through the mid and low levels will be trekking through the upper Great Lakes Thursday. In conjunction with this upper level trough will be a positively tilted elongated mid level trough that current models have extending all the way into the Great Plains.
123 AM EDT Wed Jun 12 2024 High pressure keeps warm and dry conditions through Thursday.
Early this morning water vapor satellite showed a mid level trough moving across Alberta Canada into northern Montana at 07Z. Midlevel ridging over the Rockies will build into the southern Plains as a low in the Pacific approaches Southern California. Lows tonight will be mild with lows in the lower 70s.

314 AM EDT Wed Jun 12 2024 High pressure will slowly build into the region today clearing out the stubborn clouds.
Discussion: High pressure remains in control across the region, with dry conditions and mild temperatures among a weak cu field. Recent CAM guidance hints that a isolated light shower cannot be totally ruled out in the higher elevations during peak heating, however, those in valley locations will remain dry.
Westerly flow will rule today with downsloping flow keeping temps above normal and drying out the lower levels. A weak cold front drops in out of the north late tonight. High pressure will rule on Thursday with dry conditions. Easterly low level flow will prevail behind that aforementioned cold front. This will mean somewhat cooler temps with readings mainly upper 70s to lower 80s.

Cooler today in response to a weak frontal passage.
Last night's sounding sampled a very tropical-looking profile, with well above normal moisture, high CAPE values, and a high freezing level. Overcast conditions combined with persistent rainfall has allowed for temperatures to drop into the upper 70s to lower 80s this morning, however, southerly flow has brought in dew points as high as the lower 80s this morning.
