Residents, prepare for a weather seesaw this week because of some spirited meteorological dynamics. As reported by the National Weather Service (NWS) in Cleveland, a warm front that's been nudging its way into the region this morning is associated with a low-pressure system moving northeast across the upper Great Lakes. This will set the stage for a cold front to sweep across later this afternoon, which might bring us a few showers or a rumble of thunder.
According to the NWS Cleveland's Area Forecast Discussion, "Marginal instability expected this afternoon in the warm sector with 250-750 j/kg MLCAPE overspreading the area, effective deep layer shear near 40 kts, and steep mid-level lapse rates greater than 8 C/km are supportive of a conditional severe weather threat with damaging winds and potentially large hail." However, the likelihood of severe weather seems to be taking a backseat with the best mid-level lapse rates and deep layer shear somewhat out of sync.
The winds are also expected to pick up, as gusts ranging between 35 to 45 miles per hour could sweep through the area on Tuesday. NWS Cleveland advises that we'll need to watch out for a potential Wind Advisory, although at this moment, gusts are scraping just below the criteria. And if you're feeling the chill, temperatures aren't looking to climb much above the mid-40s tomorrow.
Boaters, fishers, and all maritime wanderers take note: NWS Cleveland issued a Small Craft Advisory effective this afternoon, with a Gale Watch hot on its heels starting Tuesday morning. The Lake’s western basin could see sustained winds of 25 to 30 knots with gusts pushing 35 to 40 knots. Wave enthusiasts should be prepared for quite the aquatic spectacle, with waves poised to reach heights of 7-11 feet on the lake's east end. The lake's water levels may also dip to critical marks, so navigational caution is advised.
For those longing for warmth, there's a light—and likely warm—end of the tunnel. As the week rolls on, we can look forward to the mercury sliding back up the thermometer, with high-pressure building in and sliding east across the region. By Thursday, we could be enjoying temps reaching the low 60s. Get ready to stash away those windbreakers for a spell as brighter, milder days beckon.
