Area Forecast Discussion National Weather Service Northern Indiana 158 PM EDT Thu May 22 2025
KEY MESSAGES
- Clouds will slowly diminish into this evening.
- Most, if not all of the upcoming Memorial Day weekend appears to be dry with a few showers possible by Monday afternoon.
- While temperatures into early next week will remain below normal, they will slowly increase by a few degrees each day and return to normal levels by mid week.
DISCUSSION
Issued at 158 PM EDT Thu May 22 2025
The overall upper level flow will remain NW or W into the weekend, with any meaningful moisture and warmer air pushed well south of the area. This will allow for a much more tranquil weather pattern into the upcoming holiday weekend. In the near term, skies are slowly clearing from the NW as drier air pushes in, but a lingering pocket of colder air aloft will allow cu to pop in those areas prior to sunset. Thereafter, skies will clear even more and winds slowly diminish. Overnight lows in the NE may dip into the upper 30s, partially dependent on just how fast the last of the clouds depart from that area. As mentioned in the overnight discussion, winds should remain just high enough to limit any frost potential. Frost could possibly be a bit more of a concern Sat morning across northern areas if winds decouple sufficiently. Despite what should end up being a decent amount of sun and a overall nice weekend, temperatures will be a fair amount below normal (mid 70s) with highs in the upper 50s to mid 60s.
Although no large systems are in view, a weak trough will move into the SW US Friday and deepen somewhat as it works slowly east. Models continue to vary on handling of this feature including the track, strength and precip potential. Slgt chc to chc pops will remain in place Monday into Tuesday. Although the forecast does have us returning closer to normal by Thursday, concerned that the overall chaotic upper level flow and multiple disturbances may keep the warmest air at bay.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
Issued at 1101 AM EDT Thu May 22 2025
Much improved flying conditions in store through the next 24 hours and beyond as high pressure slowly builds in.
