Residents across the Cleveland area should prepare for a mixed bag of weather conditions, according to the latest forecasts from the National Weather Service in Cleveland. A cold front is expected to move slowly from northwest to east today through Monday morning, becoming stationary at times, before exiting the region.
Shower and thunderstorm activity will be sporadic, particularly for those east of I-71, with the heaviest concentration of precipitation anticipated in far eastern Ohio and Northwestern Pennsylvania. "PoPs do increase into the afternoon for points east of I-71, with higher chances in the far eastern Ohio counties and Northwestern Pennsylvania," the National Weather Service noted in their area forecast discussion. By Sunday evening, the intensity of rain should wane as the system progresses eastward, however, the slow-marching front will keep some areas on their toes with modest rain probabilities persisting into early Monday.
Temperatures during this period are expected to drop slightly, offering a break from the recent heat. High temperatures for today and Monday are forecasted to settle in the mid-80s, with nighttime lows dipping into the upper 60s and low 70s. Looking further ahead, a bout of high pressure is slated to bring a brief respite Monday evening through Tuesday before a warm front enters the scene midweek, signaling another round of more pronounced weather shifts.
The National Weather Service's short-term outlook suggests, "Upper level ridging will be situated to the southeast of the region allowing for southwesterly flow." This change in flow will usher in warmer temperatures and higher humidity for Tuesday and Wednesday, with highs potentially reaching the upper 80s and low 90s in some locales, and mild overnight lows staying firmly in the low 70s. Though Tuesday could see some general thunderstorms, a lack of significant instability will likely rule out severe weather. As for Wednesday, forecasters call for increased precipitation chances, but with "little model agreement, there is little confidence in the details."
Marine conditions on Lake Erie will also feel the effects of the shifting weather patterns. The National Weather Service expects southwest winds to prevail initially, ahead of the cold front's passage later in the day, with potential for brief gusts near 20 knots through sunrise. Boaters should be prepared for changing winds, moving to the west-northwest tonight and Monday and decreased winds as high-pressure builds early into the week. A reminder for those on the waters: "Winds and waves weaken to less than 10 knots across the board as high pressure builds across the region Monday night and Tuesday," the National Weather Service Cleveland office reported in their marine forecast discussion.
