Service in San Diego

in this briefing we will talk about a significant weather pattern change to

bring showering and windy conditions

this is Alex Tardy from the National Weather Service in San Diego

what is this weather pattern now bring the significant change looks like

it's gonna start on Thursday

upper level trough of low pressure will carve across the west coast

and it towards southern california this will be tapped into some tropical

moisture

the system will then close off from the rest of the jet stream

and a slow and stall over our region or across the Baja region

this will draw an gusty easterly winds

and possibly additional precipitation into the weekend

where is that tropical moisture

well currently here's an image showing the tropical moisture already coming up

from Hawaii

tapped into the system that is now approaching Northern California

what are the impacts that we are expecting for the next several days

Tuesday through Sunday

well looks like the gusty easterly winds that develop on Friday

from the east and gusty especially for mountains passes and foothills

will continue right into the weekend for the most part

also have fog and low clouds are mainly be from the clouds intersecting

the terrain the mountain slopes and foothills

we will have a snow level that's rather high on Thursday that'll come down

on Friday and Saturday to around sixty five hundred feet

and perhaps a little bit lower for precipitation widespread showers are

expected for Thursday

and into Friday with a chance a front showers continuing

over the weekend the scale for impact is shown here

mainly from showers and the breezy to windy conditions

confidence is quite high all the way through Thursday and Friday and then it

decreases quite a bit

over the weekend due to low pressure system being stalled and to our south

here's a look at precipitation map

this is the expected precipitation for the next

several days so primarily this will be for Thursday and Friday

out this forecast period widespread precipitation up a quarter to half an

inch

with amounts close to an inch a little bit more
