Discussion

A strong cold front pushed off the east coast this weekend and that ushered in a chilly Canadian air mass for this time of year. Temperatures today will struggle to reach 60 degrees for highs which is more than 10 degrees below normal for mid-May and tonight will feature temperatures dropping into the 30's in northern and western suburban locations and patchy frost is possible in the normally coldest low elevation spots. You may want to protect outdoor plants this evening if they are susceptible to cold. Another cool day on Tuesday will be followed by milder weather at mid-week and high temperatures will approach the 80 degree mark during the second half of the week. It'll very likely turn out that the low temperatures reached late tonight/early Tuesday will not be experienced again around here until next autumn.
