Prevalent onshore wind flow keeps temps below normal all week long

MILWAUKEE (CBS 58)--Don't blame me, blame the persistent and pesky onshore flow for the chilly temperatures practically all week long.  Look for highs to stay in the 50s with lows mainly in the 40s.  Warmer inland by about 5 to 10 degrees, depending on the day. Sunday night could dip into the 30s for some. Even patchy frost is possible in outlying areas.  Might want to consider covering your tender plants and vegetation just for one night.  Keep in mind an average high this time of year is approaching 70 degrees!

In terms of rain chances, Tuesday looks to be the best.  Some could see at least a half an inch.  It does look milder into the holiday weekend with highs in the 60s.  Rain chances could increase though for Memorial Day itself.  Stay tuned.
