Currently, mostly cloudy to overcast conditions prevail across Northwest Ohio, with embedded showers in this mass of swirling clouds. The upper level low is currently over Northwest Indiana, which has been weakening very steadily over the last day. This weakening will allow the upper level jet stream over Canada to pick up the remnants of the upper level low, while at the same time causing several strong shortwaves to build a rather large longwave trough. With the showers today, the National Weather Service has predicted the possibility of funnel clouds in any shower that hits your area. They said that these are not dangerous and are not the same kind of funnel clouds as the ones that form in strong thunderstorms. Do not be alarmed. If you see one, report it to the emergency manager and you can also send me pictures and I can relay them to the National Weather Service. Today, conditions are expected to remain overcast through most of the day. Due to the weakening of the upper level low, there may be some clearing of the cloud cover over the area today, as dry air tries to enter into the system. Expect highs today in the lower 60's, while some areas that receive less cloud cover may see highs in the mid 60's. Any daytime heating will cause convective instability, and combined with cold air aloft, this may cause the development of scattered thunderstorms that may produce heavy rain and some gusty winds, with the possibility of small hail also. Tonight, expect scattered light showers to continue, with continued mostly cloudy to overcast conditions likely. Expect lows in the upper 40's and maybe lower 50's, especially in areas with thicker cloud cover tonight. From Thursday through Sunday, as the jet stream begins to pick up the remnants of the upper level low, a major trough will begin to form over the Eastern United States. At the surface, a major storm system will form, as a 992 mb low forms in Southern Canada. This major storm system will cause a tight pressure gradient, allowing for strong winds to traverse the area on Friday and Friday Night. Expect sustained winds of 20-25 mph, gusting to 30 mph. This along with cloudy, showery, cool conditions on Friday, will cause uncomfortable conditions for people who are outside. This major trough, will continue to deepen, becoming another upper level low, but this time just off the East Coast. This means that we won't get the same dreary conditions that we have been having this week. By Saturday, the surface cold air mass and associated high pressure system, will allow for strong radiational cooling, and presenting the possibility of frost to the area. According to the National Weather Service, there is a strong possibility of frost Saturday, because of the forecast of light winds, clear skies, and a cold Canadian air mass. By Sunday, a lower level ridge is expected to move into the area, bringing a very dry, but warmer air mass into the region. As next week progresses, an upper level ridge will also move into the area, influencing the weather over a large part of the United States. With this ridge, I expect temperatures to be warm, while skies will be clear and free of rain. As I said in yesterday's forecast, temperatures could even warm into the upper 70's and lower 80's by next Wednesday or Thursday.
Wednesday Night: Low 49. Scattered to numerous showers over the area. Overcast at first, becoming mostly cloudy. Chance of rain 70% decreasing to 30%. Fog possible.
Thursday: High 71. Mostly cloudy. Instability and shear will be enough to generate widespread showers and thunderstorms, with some severe by afternoon, especially in Northwest Ohio. Patchy fog possible in the morning. Chance of rain 90%.
Thursday Night: Low 51. Overcast. Widespread showers likely, especially after midnight. Chance of rain 30% at first, becoming 70% after 3 a.m.
Friday: High 56. Overcast. Windy. Winds from northwest at 20-30 mph. Scattered showers throughout the area. Showers likely.
Friday Night: Low 37. Mostly cloudy in the early evening, becoming clear after 9 p.m. Windy at first, becoming calm later in the evening. Frost possible, especially in the early morning hours.
Saturday: High 56. Mostly sunny. Much drier than in recent days. Very nice day, but chilly at the same time.
Saturday Night: Low 35. Mostly clear. Light winds and clear winds, make for a great night for the formation of frost. Some areas, especially north of here, could hit below freezing, especially in more isolated areas.
