Independence Day in the Valley: Hot, very humid with isolated storms

Conditions across east-central Ohio have not changed much over the last 24 hours. A weak frontal boundary that crossed the region yesterday producing a few showers and thunderstorms continues to slowly drift south this morning. The boundary will lift north again this evening and once again, showers and thunderstorms will threaten in the afternoon.

Much like yesterday, some will get a storm while other areas will stay dry. There is still abundant moisture for storms to work with and there isn’t much air movement aloft. Any storms that happen to develop this afternoon won’t move much and will be capable of producing heavy rainfall. Another concern with today’s thunderstorms will be frequent and intense lightning. Severe thunderstorms are not expected.

Simulated radar through midnight:

Temperatures this afternoon will again reach the upper 80s to near 90 in most neighborhoods. High dew points will push heat indices to the mid/upper 90s.

The threat for showers and storms will fizzle out after sunset and daytime heating begins to cool. Fog will be an issue overnight in those areas that get rain. Otherwise, warm and muggy conditions will persist again tonight with lows only dipping to the low 70s.

INDEPENDENCE DAY
Nothing much changes in the hot and humid weather pattern for the Fourth. A spotty shower or thunderstorm will again threaten as temperatures heat up in the afternoon. Coverage for storms tomorrow looks more isolated, though, and most spots should remain dry.

With a bit more sunshine on Wednesday, temperatures will reach the low 90s just about everywhere. The soupy airmass will push heat indices to 100/102 degrees during the heat of the day. The best place to celebrate will be at the lake or anywhere that’s air conditioned.

Expect another warm and very muggy evening if you’re headed out to watch fireworks.

THURSDAY AND FRIDAY
Thursday looks to bring another warm and humid day to the region with spotty showers and storms – no surprise there. However, there are changes in the weather pattern afoot for Friday.

A nice cold front will cross Friday afternoon bringing showers and thunderstorms probably early in the afternoon. Behind the front, cool and dry air will rush into the region flushing the hot and very humid airmass out. Showers and storms should end by Friday evening.

There are some timing issues yet and depending on how early/late in the afternoon the front crosses, storms might be strong to severe. Early would be better.

WEEKEND OUTLOOK
In a word – beautiful. Saturday will feature temperatures back near normal with high pressure providing the sunshine. The most dramatic change, though, will be the dry air. Dew points will drop back to the mid-50s and refreshingly less humid.

Sunday will be just as nice with afternoon temperatures in the low 80s.

EXTENDED OUTLOOK
Des[ite the weekend cooldown, the extended outlook promises a warmer than average trend in the 8 to 14 day outlook from the Climate Prediction Center.

Probably not as hot of a pattern as we’re in now, but still, not a cool pattern. It appears we can look forward to warm weather at least to mid-July.

As for rain, the CPC also predicts a slightly wetter than average period.

Thanks for reading Tuesday’s Tuscarawas Valley weather update. Have a safe Fourth of July.
