SHORT TERM [Today through Sunday]... Isolated to widely scattered showers were noted over coastal waters this morning; their development due in part to instability over warm waters, but also due to the inverted trough slowly sliding west across southwest LA this morning. These showers will continue to develop throughout the morning, though they will remain over coastal waters thru sunrise as northerly flow pushes them further offshore. The localized area of low level lift combined with instability from daytime heating will send scattered to numerous showers and storms over the area again today, with higher Probability of Precipitation chances concentrating over the lower portion of the area. Wind fields on local forecast soundings indicate deep north to northeast winds which are advecting dry air aloft over the region from north to south. This will hinder the amount of convective coverage that can spread inland throughout the afternoon.
A similar story is in store Saturday and Sunday as upper level ridging noses down into the Deep South, further spreading dry air aloft over the region. Rain chances will primarily be driven by diurnal processes with some waning influence from the surface disturbance sweeping westward.
LONG TERM [Monday through Thursday]... The early part of the long term period continues to see a mid/upper- level ridge build over the area from the southern Plains/Rockies, with rain chances looking rather seasonal. Best rain chances remain over the sern zones where best moisture/least capping linger. However with reduced rain chances and cloud cover, the heat makes a return to the forecast, especially over the far nwarning zones where highs are forecast to nudge back into the mid/upper 90s.
POPs creep back upward a bit for Wednesday as a cutoff low sitting over the St. Lawrence Valley sees a series of shortwaves rounding it, breaking down/retrograding the ridge and weakening the cap. Rain chances further increase for Thursday with the approach of a backdoor frontal boundary.
A frontal system will stall north of the coastal waters on Saturday. This will keep mainly light to occasionally moderate onshore flow into early next week as surface high pressure will continue to ridge across the northern Gulf of Mexico. Scattered showers and thunderstorms will continue in the coastal waters through much of the upcoming week, especially through the morning hours each day. Expect elevated winds and seas near storm activity.
