SVR RISKDES MOINES, Iowa – Strong winds, showers and thunderstorms return to the forecast Wednesday.

As a strong area of low pressure to the north closes in on Iowa, it will draw in a gusty south wind at 25 to 35 mph. “The strong winds will push us close to the warmest temperatures of year with highs into the 80s, said Meteorologist Brett McIntyre.

With the dry conditions across much of the state, fire danger will again be high. A Fire Weather Watch is in place for the Eastern 2/3 of the state from 10 a.m. to 7 p.m..

Some relief to the dry weather will come late Wednesday into early Thursday. A cold front will dive across the Midwest on Wednesday afternoon, and will fire up thunderstorms into the evening to our west. There is a risk for some severe weather across South Dakota and Nebraska through the evening, as well as extreme NW Iowa. Hail and gusty winds will be the main threat in those areas.

However, the cold front — and accompanying storms — will not reach Central Iowa until midnight or later. With substantially less​ heat to work with, conditions will be much less favorable for strong storms in Central Iowa. The overnight will feature much more general thunderstorms and rain, which remains much needed in all parts of the state.

Rainfall totals by Thursday mid-morning should approach three-quarters of an inch in many spots, with totals over a inch likely in areas that see more thunder during the overnight.
