Challenges: It will be very cold our west highlighted by a major spring snowstorm in the Rockies, including Denver. They could get up to 12” of snow with temps down to as low as 20 degrees. Nasty. As this cold pushes east it will moderate. However when one area gets really cold, another will warm up. We are on the warm side.
For midweek an onshore flow will develop as a high moves into Maine/SE Canada. This will bring low level clouds off the Ocean/up the Chesapeake Bay into our area. This will really cool up off on Wed. Frontal boundary moves through Thursday with rain/storms.
The weekend could be very, very wet. It all depends on the next trough. If it acts like a bowling ball, just expect showers and a few storms to be around each day. If it is more of a north south oriented boundary, then expect heavy to locally excessive rains. It is a tough call. One that cannot be made at this point. Right now expect it to be unsettled next weekend.
This pattern is likely a preview of how the summer will go. Colder west, with good moisture moving north out of the Gulf of Mexico. Summer should be warm and humid. I do not anticipate long drawn our heat waves, nor any long dry spells. This ought to be a good growing year again, like last summer.
Today: Sunny. Very, very nice. High: 76. Low: 55.
Monday: Mostly Sunny. Warmer. Still very nice. High: 82. Low: 60.
Tuesday: Sun mixing with clouds. It will be cooler esp. to our east. It is possible that Allentown will stay in the low 60s all day. If the clouds persist longer, it will be cooler. Showers should stay to our west. Some drizzle is possible at night. High: 76. Low: 55.
Wednesday: Lots of clouds. Humid, but on the chillier side. Much cooler. Showers are possible esp. late in the day, but nothing significant. Some patchy drizzle could occur. High: 65. Low: 54.
Thursday: slow moving system and frontal boundary will move into the western part of the state and into our area later in the day. Expect some heavy showers/storms giving 1/2 to 1” of rain. Becoming mostly cloudy. High: 70. Low: 60.
Friday: Becoming mostly sunny. Much colder with gusty winds. High: 65. Low: 42.
Saturday-Sunday: Sun and increasing clouds Saturday. High Sat: 69. Low Sat: 50. Some rain possible Sat night into Sunday. Have to watch for the potential of very heavy rains Sat night through Sunday on this system. It is not etched in stone. Just something to keep an eye on. High Sun: 68. Low: 55.
