- Cooler Temperatures and a Chance of Showers Today
A low pressure center in the lower levels of the atmosphere will move across the Ohio river valley region today while a positively tilted upper level trough sinks south over Michigan from northern Ontario. East to northeasterly winds will prevail with mostly cloudy skies. Today will be the start of a few days of cooler than normal temperatures.
Trends have continued to reduce the probability of precip throughout the day and also decrease the rain totals over much of the area. The rain associated with the Ohio valley low may stay mainly south of I- 96 with the heavier amounts south of I-94. The HRRR 24 hours ago was bullish on 0.5 to 1.0 inch QPF over much of the area, but now 0.5 seems unlikely for most while parts of central Michigan may stay dry. The temperature forecast today has been nudged up slightly, particularly northwest of Grand Rapids where it may reach the mid 60s. Amid the northeast winds, there may be low topped surface-based convective showers developing afternoon-evening between Reed City, Ludington, and Muskegon.
Light winds and clearing skies tonight may let temperatures dip into the 30s with a chance of frost in the highlands of interior north- central Michigan, Leota-Tustin area and north.
- Possible Shower/Storm Saturday and Frost Saturday Night
Shortwave trough arrives Friday night with a clipper-type low bringing showers and a few thunderstorms lingering into the afternoon given the steeper lapse rates. Cool air in northerly flow on the back side of the sfc low results in low temperatures in the upper 30s to lower 40s Saturday night with scattered frost potential in the colder outlying areas.
- Low Confidence in Forecast Details Next Week
Shortwave ridging on Sunday eventually gives way to another trough Monday with some showers and a few thunderstorms possible along a cold front. There continues to be low confidence with forecast details by the middle of next week as the GFS goes out of phase with the Euro and GEM. There continues to be a general signal for a longwave trough forming across the central/eastern CONUS by late in the week which could bring some showers and storms by Thursday.
AVIATION /12Z TAFS THROUGH 12Z FRIDAY/
Issued at 723 AM EDT Thu May 9 2024

MARINE
Issued at 335 AM EDT Thu May 9 2024
