* WHEN...Through Thursday afternoon.

* IMPACTS...Excessive runoff from significant snowmelt and a general half to three quarters of an inch of rain may result in flooding of rivers, smaller tributaries, and other low-lying and flood-prone locations. The most prone areas for flooding will be where ice jams typically develop. The greatest risk for ice jam flooding will be Wednesday through Wednesday night with the risk for river based flooding coming mainly Wednesday night through Thursday.

* ADDITIONAL DETAILS...An intense storm system moving across the central Great Lakes will send a surge of Spring like warmth to our region through Wednesday evening. Temperatures will only fall back to the lower 40s this evening before increasing overnight. Widespread 50s are forecasted for the entire region for Thursday. These temperatures will be accompanied by a general half to three quarters of an inch of rainfall. The fast melt off of the snowpack will combine with this rainfall to cause significant rises to area tributaries with flooding becoming possible. Flooding concerns will be particularly elevated in areas where tributaries are prone to ice jam flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
