Upper level jet stream winds will flow nearly west to east over the Ohio Valley much of
the week ahead. This will allow the southern flank of cold Canadian-source high pressure
to maintain a foothold over Chicago. Through Tuesday, high temperatures will average
nearly 13 degrees below normal, then a moderation the latter half of the week will bring the
overall 7-day high average through next Saturday to about 7 degrees below normal.
Chicago will be situated on the northernmost side of low pressure systems passing far to
the south early in the week, giving cloudiness and periodic light snow or flurries.
Brief clearing should occur on the backside of low pressure on Wednesday, then a cold front
will drop temperatures and give another round of flurries Thursday and Friday. If computer
models prove correct, a brief one-day surge of warmer air could occur next Saturday,
just in front of another cold front next Sunday.
FLORIDA WARMS UP AFTER COLD SPELL
After low temperatures dropped into the low 20s across the north, and the mid-30s in
central portions of Florida this past week (some 15 to 20 degrees below normal) readings are
expected to edge up closer to normal levels this week.
