***WINTER WEATHER ADVISORY in effect for most of the viewing area from late Sunday morning through early Monday morning***
High pressure brought plenty of sunshine to the area on Saturday, so look for clear skies to start off our night. However, as we move through the overnight (and into March) skies will cloud up as the next low approaches from the west. Overnight temps will still bottom out in the low double digits and high single digits.
Spotty, light snow showers will start in the mid to late morning hours on Sunday before steadier snow overspreads from west to east the area during the afternoon. The snow will continue into the evening and overnight period at which time some mixing will sleet and freezing rain is possible, especially south of the Lehigh Valley. North of the Lehigh Valley it will be almost all snow for the entire event. When the precipitation comes to an end around midnight Sunday into Monday the snow/ice accumulations will be around 2-4" of snow for most of the viewing area. Southern Berks and south of the Lehigh Valley 1-2" is possible with northern Pennsylvania entering the 4, 5 and 6 inch range. (see map below). Totals will be dependent on the duration and how fast we mix with ice/rain. We'll continue to monitor the details of that system, so stay tuned for the very latest.
Highs on Sunday will reach into the upper 20s and low 30s, but may rise through the overnight period Sunday into Monday. On Monday highs will top out near 40 degrees as the clouds give way to some sunshine. Keep mind though that even with the precipitation ending by daybreak on Monday there will still be some slick spots on area roadways for the Monday morning commute.
