Big weather change coming

Light freeze possible mountains, frost possible away from 285 Thursday morning

We are days past the average last freeze date based on climatology (past weather history) but a chilly air mass in April is not that unusual.

A southward dip in the jet stream is projected with late-season snow expected in some Western and Northern states today into Thursday.

The cold air mass on the backside of that snow system will send a cold front through Georgia Wednesday with below-normal temperatures returning for a few days.

The chance of a shower Tuesday ahead of the front is not zero but is too small to worry about.

Gusty North winds will add a chill to the air on Wednesday.
