Don't take down those St. Patrick's Day shamrocks yet. They might be the only verdant things around Williamsport for a good while.
Budding green things will have 4 to 6 inches of snow to pop through after today, according to the National Weather Service.
A winter storm warning for the region will be in place from 8 a.m. today through 8 a.m. Tuesday.
Flowers begin to unfurl Sunday afternoon at the M&T Bank building on Broad Street in Montoursville.
"We'll have snow developing in the morning and continuing into the afternoon," said Craig Evanego, a meteorologist at the weather service's State College bureau. "Eventually we should see things change over to a bit of sleet or freezing rain."
Any changeover will take place late today, with precipitation expected to taper off by Tuesday morning, Evanego said.
"We'll be flirting with the freezing mark, so it could become freezing rain, a wintry mix or just plain rain," Evanego said. "It'll be a little milder with highs up into the mid-40s Tuesday, and it looks quieter after that."
On Wednesday and Thursday, expect to see the sun sometimes through the clouds, with temperatures in the mid-30s.
"It should be partly sunny and in the upper-30s again on Friday," Evanego said. "Right now the weekend looks partly sunny as well with highs into the low-40s."
Temperatures this week are "well below normal," Evanego said. Lycoming County usually has high temperatures in the high 40s at this time of year.
Through the month's end on Easter Sunday, the weather service's Climate Prediction Center is "keeping it on the cool side," Evanego said. "It looks like we'll remain below normal temperature-wise right on through the end of March."
