Temperatures... Seasonable temps Sunday then a pronounced warming trend is expected Mon through Wed as SW flow develops with warming 925/850 mb temps. Peak of the 925/850 mb temps is Tue when highs may reach into the 50s in portions of the coastal plain, especially if there is sufficient sunshine. NBM indicating 40-60 percent probs of temps over 50F Tue across RI and SE MA. While low level temps are cooling Wed, favorable W-NW flow behind the front and deeper mixing may result in another day with highs 50+ in the coastal plain. NBM probs of 50+ are 20-40 percent on Wed. Confidence in Thu temps is low as a possible surge in 925 mb temps ahead of next system may be offset by cloud cover and potential precip limiting how mild it gets. This will all depend on the timing of this system but it could be another mild day Thu in the coastal plain with 50 degree temps if system is slower.
It's here, it's Spring!
