DISCUSSION

KEY MESSAGE 1
The fcst remains on track for warm wx this week. The NBM was generally followed, although temps along the coasts of NY and CT were adjusted upwards today and Wed closer to the MAV and MET.
It looks like the numbers may be weighted a little to heavily on the 2M model data in those spots. Similar adjustments may need to be made for both Thu and Fri. A lack of strong wly flow limits confidence in these areas torching out, but adjusting towards the MOS seemed fairly safe given the warm airmass building in.


KEY MESSAGE 2
Some shwrs and tstms possible thru the week with the area warm sectored. The main convergence zone however looks to remain N and W of the cwa. In this scenario, would expected initiation to generally occur outside of the cwa, then bleed into the area on storm flow or convectively induced boundaries, especially across the interior, for the late aftn and eve hours before completely falling apart. A shrtwv near the end of the week could provide a better focus for both initiation and intensity, but the timing will need to work out to allow for some instability to work with. Although the 00Z GFS has this feature passing thru during the day on Fri, the quicker AI-GFS produces practically nothing with an early mrng passage. Stuck with the NBM for pops and wx throughout the fcst.


KEY MESSAGE 3
A strong cold front is forecast to move through the region during Sunday, while there are still some timing difference, consenus is for a cold frontal passage Sunday afternoon. Showers will accompany the passage, with a chance of thunder as well.
After a prolonged period of above normal temperatures, the cold front passage will return temperatures to near to slightly below normal Sunday night through Monday night.

AVIATION /14Z TUESDAY THROUGH SATURDAY/
Offshore high pressure to the south will remain in place. Weak low pressure will pass across upstate New York and New England late this afternoon into this evening, bringing a front closer to the Hudson Valley terminals.
