.SYNOPSIS FOR MID ATLC WATERS...Intensifying low pressure 
near Georges Bank will track NE across Nova Scotia early today 
while pulling a strong cold front over the SE portion. Strong 
high pressure will build E towards the coast today and tonight, 
move offshore over the N waters Tue, then weaken Tue night. 
Another developing low will move NE across the far S portion Tue 
night while pulling a strong cold front over the area. The low 
will move off to the E of the area Wed as the front moves off to 
the SE of the waters. A low pressure trough will form along the 
SE coast Wed night, then lift N and transition to a frontal 
boundary Thu into Thu night as yet another low pressure system 
develops over the area. Another high will build E over the N 
portion Wed night into Thu, then shift E of the area Thu night. 
The intensifying low will reach the N waters early Fri, with the
low moving off to the E and NE of the area later Fri into Fri 
night as a high pressure ridge builds E towards the coast.
