These storms will decrease but then re-fire along a trailing cold front later in the day Thursday, though with much less coverage and intensity than recent events.
347 PM EDT Wed May 8 2024 Low pressure will lift a warm front north across the region late tonight into Thursday. High pressure has allowed for a period of dry weather today. As the high exits the region tonight a warm front lifts northeastward and will allow for high level clouds to begin to filter in tonight. This low will take its time exiting the region and will keep rain chances in the forecast through the end of the period. Highs tomorrow will be cooler as they will rise into the upper 50s to lower 60s. We start the short term period with an upper-level trough overhead.
354 PM EDT Wed May 8 2024 - Much cooler on Thursday with rain expected south of M-59 and a chance north.
High pressure will build inland through the rest of the week and into the weekend, kicking off a warming trend.
Our stagnant mid/upper level low pattern will slide east tonight, setting up a nearly horizontal, positively-tilted trough axis along the Minnesota/Iowa/SoDak border region. The main threat will shift to locally heavy rains overnight, with the highest totals expected south of the MN/IA border. Northeasterly flow behind the occluded front will advect in slightly cooler and drier air, leading to quiet weather tomorrow afternoon/night.
Temperatures are expected to be even warmer on Thursday, with highs in the triple digits, away from the coast.
1202 PM CDT Wed May 8 2024 (Today and tonight) As of 2 AM CDT, a shallow surface cold front is across the central Texas Panhandle and is expected to continue to push southward through the forecast area this morning. The upper closed low continues to wobble over the Northern Plains today with another vort lobe ejecting around the southern periphery of the low.
The quiet and toasty weather will continue as high pressure over the western Atlantic remains in charge of our weather here along the Florida Keys.
This will last through the evening for most areas, except near the New York State Thruway corridor, where a weak cold front could set off a few additional thunderstorms.

Surface cold front, marked mostly by a moderately sharp dewpoint drop, extended from the Poconos of NEPA to the Lower Susq Valley at 1830Z. Temps are right around their fcst highs, varying from mainly the mid 70s across the higher terrain of the north and west to the mid 80s throughout the Southern Valleys and Lower Susq Region. Periods of chilly rain continue Thursday afternoon and night with low clouds/fog shrouding the ridges.
- Warmer and mainly dry conditions move in for the weekend. Overall instability not that high, but with the freezing level around 6-7 kft it will be pretty easy to get some smaller hail. The upper level low pressure shears out and sags south tonight into Thursday. Temperatures will also be a touch cooler as winds turn northerly and some diurnally driven cloud cover is expected to develop.
Latest upper air analysis shows a closed low over the Northern Plains. Water vapor imagery indicates dry air over the Plains feeding into the low. A weak cold front will move through around sunrise. The upper level low currently north of the forecast area will elongate to the southwest, positioning itself over the Four Corners Region. During the late afternoon a short wave trough will round the closed low. The short wave trough may graze the western part of the forecast area during the afternoon. A stationary elongated trough looks to be set up across the Inter Mountain West which looks to bring precipitation to the Rockies and just to the east.

Any landspout/funnel potential this afternoon looks to be best over southeast SD, under the upper low center.
While the upper low supplying all the weather we've seen the past few days is now located in western South Dakota and slowly progged to move east over the next day, wrapping around it is still an abundance of moisture flowing in to southern and central Montana. Upslope into the foothills and mountains is deep as well, and with a lot of moisture still available upstream, the current rain over the lower elevations and snow in the higher foothills and mountains will persist through tonight at it's current rate. Across the lower elevations, rain will persist through the afternoon with the aforementioned moisture upstream continuing to move south into southern MT with it's upslope flow.

Meanwhile, high pressure along the Appalachians will keep easterly to southeasterly flow at the surface. The trough will dig into the Intermountain West by tomorrow, which will help to briefly amplify the ridge over the Southeast. However, as the ridge amplifies and expands to the west, subsidence is expected to overcome the increase in moisture over the area, though mid and high level clouds will persist. The above normal temperatures will continue, as highs reach into the lower to mid 80s on Sunday. Overnight lows will fall into the lower 60s across our northern areas to the upper 60s across the south.
