From LOT AFD:
pressed south by blocking over central NOAM, we`ll have an
exceptionally long period of benign weather with surface high
pressure predominating through mid next week. Winds will be
generally from the northeast, resulting in rare winter time
"cooler near the lake" conditions lakeside amidst otherwise well
above normal temperatures in the 40s (with upside potential
pending sky cover trends). Next chance of precipitation will
come beyond day 7. The tendency during this stretch will be to
wonder if "winter is over", though consistent long range
ensemble guidance has been pointing toward the return of a more
wintry pattern (western ridging and eastern troughing with high
latitude blocking establishing), at least temperature wise,
toward Valentine`s Day.
