Let The Warm Up Begin 80s Highs Next Several Days

The last of these weak upper troughs is now to the east and we see clear skies over most of the arear on the satellite picture. Clouds and some scattered showers well to the southwest of us will never get here as a strong ridge builds along and more importantly inland of the East Coast. This locks us in for sunshine today and for at least the next few days..

Temperatures this afternoon will reach the upper 70s and lower 80s just about everywhere and that includes coastal areas usually at risk for an all day long ocean wind. The wind off the land will keep sea breezes confined to the immediate coast for most of day allowing temperatures to climb. The risk for a shower or thunderstorm today is confined to areas east of NYC in parts of New England.

The nice thing about this warm up is that it comes with low dew points in the low to mid 50s. The northwest flow aloft will keep dew points on the low side right through Friday which means that while the temperatures will be very warm, the humidity will be low and therefore it will be comfortable.

Skies should be clear tonight with most lows in the low to mid 50s with 40s away from the warmer urban centers. That sets us up with a good solid launching pad for Wednesday. Plenty of sunshine is forecast and highs will reach the mid to upper 80s. It will be a little cooler along the immediate coast along south facing shorelines with a bit of a sea breeze developing in the afternoon.

Isolated 90 degree highs are possible both Wednesday and Thursday. Thursday morning we will start out in the 50s to near 60 degrees and another day of sunshine will take temperatures Thursday to the mid to upper 80s again and the outside chance that someone gets to 90.

We have what is known as a strong “omega block” which looks like the Greek letter Omega (an upside down U shape). Deep intense lows lie on either side of a strong upper ridge in the middle. If you are under the upper high you are generally in the sweet spot weather wise with very warm temperatures and not much if any precipitation except maybe on the edges. Thursday night could see a weak trough coming south on the east side of the upper ridge so we will throw in the chance of an isolated shower or thunderstorm, mainly along the coast.

The character of o ur weather with change a bit on Friday as the upper ridge begins a slow migration westward and that puts us at risk of upper air troughs coming down from the north. Friday should be partly sunny with 80s for highs from NYC south and west with mid to upper 80s across Southern Pennsylvania and Southern New Jersey south. 70s are going to be coming north and east of NYC in Southern New England. Look for the chance for a shower or thunderstorm on Friday though dew points will still remain reasonable.

There weekend brings some complications. The Omega block retrogrades west as the upper high moves into the Middle Mississippi Valley. This puts us in an increasing northwest flow aloft and upper troughs will be dropping southward. One such trough could trigger off scattered showers or thunderstorms Saturday in between cloudy to partly sunny conditions. It will start to turn a little more humid over the weekend as dew points rise.

Sunday sees a cold front approaching and ahead of it we should be partly sunny with highs into the 80s. There is the chance for a shower or a thunderstorm when the front passes. Next week we lose the big ridge and the omega block but temperatures should still remain above average with highs in the upper 70s and lower 80s for Monday. Next week’s pattern is going to be a bit different than this week as weather systems will be moving along and that means weather fronts coming through We could be back into the 80s into midweek before another cold front passes through.
