Almanac weather predictions
Hi Miranda, We only post the current and next month of predictions on this Companion web site, as a courtesy of The Old Farmer’s Almanac publication. You’ll need to consult the little yellow book for our full year of predictions. Btw, The 2021 Old Farmer’s Almanac should be out in a month or two! That said, we can tell you hot weather will be continuing into August. See our 2020 Summer Weather Forecast here.
rain
Northeast and Central Pennsylvania did not receive much snow last winter nor a great deal of rain in the spring; it was to warm for snow, but to dry to rain. If we are to avoid a drought we need more rain this summer and more snow this winter.
