Discussion: Areas of high pressure continue to dominate our pattern. A high is currently tracking from just N of the Great Lakes towards the Atlantic Ocean (over Cape Cod area). This will start everyone out with onshore flow (over 60-degree water) for Monday. The high sun-angle will take us up to about 70 but that’s it. A cool and refreshing day after the recent few hot days. As the high tracks, our flow will switch from E to S for Tuesday—allowing a warmer day than Monday but not yet hot. Wednesday seems like the hot day of the week with SW return flow from the ocean high. A cold front should push through Wednesday night into Thursday morning. Showers and thunderstorms are possible along that front. Another high is then expected to take a similar track (N lakes to Atlantic Ocean) but with a series of low pressure to the S of it. It’s still a bit early for the official Memorial Day Weekend forecast but right now Friday and Monday are looking like the better days. Saturday and Sunday are modeled for wet onshore flow associated with the N/NW side of the low pressure.
Monday (May 24) high temperatures should only reach near-70 for most areas. Skies should be mixed with sun and clouds. A refreshing feel after recent heat. Winds should be light out of the E, breezy at times for coastal areas. Overnight lows should fall into the 50s.
Tuesday (May 25) high temperatures should reach the mid-to-upper 70s for most area. Closer to 70 near the coast. Skies should be mixed (more sun then clouds). Winds should be light out of the S/SW. Overnight lows should fall to the lower-60s.
Wednesday (May 26) high temperatures should break 90 for most areas. Coastal regions could hang in the upper-70s/lower-80s. Skies should be mostly sunny but afternoon isolated pop-up showers and thunderstorms are possible. Winds should be light out of the S/SW. Overnight lows should fall into the 60s.
Thursday (May 27) high temperatures should reach the mid-80s for most areas. Skies should be mostly sunny. Winds should be light out of the W/NW. Overnight lows should fall into the 50s for most areas.
Friday (May 28) high temperatures should reach the mid-to-upper 60s for most areas. Skies should be mostly cloudy with rain possible. Winds should be light-to-breezy out of the NE. Overnight lows should range from mid-40s to mid-50s from NWNJ elevations to SENJ coasts as rain chances continue into early Saturday morning.
An early look at the weekend indicates Friday and Monday the best days. Saturday and Sunday are modeled cloudy and rainy. Guidance should be within a more confident range Wednesday so I am waiting until then to form any forecasts for Memorial Day Weekend. Everyone have a great week and please be safe! JC
