DES MOINES, Iowa – Showers and thunderstorms moving across the state on Monday are just the beginning of what could be an active weather day Tuesday into early Wednesday.

According to Meteorologist Megan Salois, Tuesday will begin with morning sunshine and humid conditions. A cold front will approach Iowa from the north and will meet up with a strong storm system that is pulling in moisture from the remnants of Hurricane Norbert in the Pacific Ocean. The moisture, in combination with the cold front, could produce conditions that may produce thunderstorms capable of producing heavy rain. The storms could also produce large hail, damage winds and isolated tornadoes.

Storms are expected to develop in southwestern Iowa during the afternoon hours Tuesday and move to the east. Storms are forecast to move into the Des Moines-metro area, and other communities along Interstate 35,  by 5 p.m.  Salois warns that heavy rains could lead to flash flooding on area roads where sudden heavy downpours don’t drain quickly.

The storms don’t look to end until the early morning hours of Wednesday. Rainfall amounts will range from under 1″ in Northern Iowa to as high as 4″ in a few locations in Southern Iowa.

Wednesday will be calmer and cooler with overcast skies and highs only near 70 degrees.

    Hey,, Megan,, what’s the black (very dark grey) matter south of Iowa City represent; do we even want to know?

    You really make it appear so easy together with your
    presentation but I to find this matter to be actually something that I feel I’d by no means understand.
    It seems too complicated and very wide for me. I am looking
    ahead on your subsequent put up, I’ll try
    to get the hold of it!
