FREEZING RAIN ADVISORY tomorrow from 4am to 9am for most of the area. It lingers until noon for Dauphin, Lebanon and Schuylkill Counties.  A frontal system approaching from the west will bring in precipitation early tomorrow morning while temperatures are still at or below freezing for a bit.  Temps should warm above freezing causing any freezing rain to change to rain.  Some typically colder spots may remain below freezing a bit longer resulting in the freezing rain to continue.  Rain and freezing rain may start as early as 7am, transitioning to all rain once temps warm above freezing. We should see the system move out by noon time leaving the rest of the day dry with decreasing clouds.  Winds may pick up a bit in the afternoon.

TIMING: Early morning Wednesday. Temps warm above freezing mid morning.

IMPACTS:  Untreated roads, bridges and sidewalks may briefly develop a coating of ice making for slick conditions.

AMOUNTS:  A thin glaze is possible.

TONIGHT:  Clouds break up for several hours as high pressure moves overhead.  This has allowed temperatures to plummet quickly to the upper 20s. This causes concern for black ice or icy spots to develop on roadways and bridges.  Use caution if heading out. Temperatures will hit lows just after midnight before clouds return. Temps may hold steady then begin to rise towards morning.  However, our next system moves in early and rain may start to fall before temps get above freezing, which is 32 degrees.  This means the rain will freeze on contact, so a period of freezing rain is possible until we see temps warm above freezing.  It should transition quickly in most areas to plain rain as temps continue to rise above 32°.  Not a lot of moisture with this next system so it should move out quickly.

WEDNESDAY: Shower threat ends by noon time.  Clouds will decrease as the next high pressure system slides in.  High should get to the low 40s for most but further south may reach upper 40s. Clear skies Wednesday night into Thursday will lead to lows in the middle 20s once again.

FREEZING RAIN ADVISORY issued for tomorrow

THURSDAY AND REST OF WEEK:  With high pressure overhead, plenty of sunshine should get our temps once again to the low 40s before the clouds move back in ahead of a warm front. There may be a stray shower in the evening but most of the area looks to remain dry for now. Friday will bring the best chance for rain as a potent storm system rides in. Showers chances are highest in the early part of the day.  Despite wet weather, temperatures look to make into the low 50s after a very mild start around 40 in the morning.

WEEKEND OUTLOOK:   We start the weekend dry, mostly sunny and around 50 degrees but the next system moves in Saturday night into Sunday ushering in colder air and it is possible we may dodge a few light snow showers. System is not showing a lot of moisture so anything we get will be light, highs only in the upper 30s to near 40.

Be careful in the morning and enjoy the rest of the week and the milder temperatures to come!
