High pressure aloft and at the surface will dominate our weather pattern Sunday and Monday. Temperatures on Sunday will warm to around average as the high slowly makes its way east. Some thin high cirrus will creep in during the afternoon but this will do little to impede the sunshine.
With high pressure to our east on Monday, warmer and more humid southern air will begin to enter east-central Ohio. Dew points will increase but it will still not be as oppressively humid as we were last week. Temperatures will also increase with the southerly flow. Afternoon highs on Monday should reach the mid to upper 80s in most locations.
An upper-level disturbance will push a cold front through east-central Ohio on Tuesday raising the possibilities for showers and thunderstorms. As of Sunday morning, support for any strong to severe storms looks unlikely.
Timing issues regarding the arrival of the front make the forecast for afternoon highs on Tuesday a bit tricky. I went with mid-80s for the time being but these may have to be adjusted upward should showers and storms move through later in the afternoon.
High pressure over the Great Lakes region will return on Wednesday to bring back the sunshine. Temperatures will be a few degrees cooler once again behind the front under a strong northerly flow. The high will also keep TS Chris off shore along the East Coast.
High pressure will keep us dry through the end of the work week. Temperatures and moisture will gradually increase as the high shifts east by Friday setting up that southerly flow again. Afternoon temperatures will creep back up to the upper 80s to near 90 by Friday. The added moisture will also push dew points back up to uncomfortable levels for the weekend.
No significant chances for showers and storms through the weekend, but with an increasingly warm and humid airmass in place, look for occasional isolated showers and storms to develop through the period. Look for afternoon temperatures in the 90-degree range with dew points in the very muggy 70s again.
Generally dry conditions should persist through the week with only light accumulation over the next seven days. Most accumulation for the week will occur Tuesday with showers and thunderstorms from a cold front.
Humidity levels increase the latter part of the week and will continue through the weekend.
