Discussion

Onshore flow will cool temperatures by mid-week to near normal, but then a warming trend will occur by the weekend. There is a slight chance for some shower activity during the mid-week time frame, but so far, it appears that most of this will remain to our north.

7:00 AM | What a change for this week compared to last

6-Day Forecast

Today

Partly sunny, pleasant, upper 60’s

Tonight

Mostly cloudy, cold, mid 30’s

Tuesday

Mostly sunny, still pleasant, upper 60’s

Tuesday Night

Partly cloudy, chilly, upper 30’s

Wednesday

Partly sunny, pleasant, upper 60’s

Thursday

Mostly sunny, nice, near 70

Friday

Partly sunny, cooler, low-to-mid 60’s

Saturday

Mainly cloudy, maybe a few showers, cool, low 50’s

Discussion

A ridge of high pressure building in the upper atmosphere will keep us rather pleasant for much of this week; especially, when compared to the cold of last week. In fact, temperatures will move to well above normal levels for the majority of the week thanks to the large high pressure system.

7:00 AM | Offshore gusty winds promote more warming, drying and an increase in fire danger

6-Day Forecast

Today

Mostly sunny, windy, warm, near 80 degrees

Tonight

Mostly clear, breezy, mild, lows near 60 degrees

Saturday

Mostly sunny, breezy, very warm, low 80’s

Saturday Night

Mostly clear, mild, near 60

Sunday

Mostly sunny, very warm, low 80’s

Monday

Mostly sunny, not quite as warm, mid 70’s

Tuesday

Partly sunny, not as warm, breezy, low 70’s

Wednesday

Partly sunny, even cooler, upper 60’s

Discussion

An offshore flow of air will continue today and right through the weekend and this will raise temperatures, produce very gusty winds and increase fire danger to close out the work week. The offshore flow weakens over the weekend and there will be a slight cool down early next week.

7:00 AM | Cold with snow showers again today and then bitter tonight; moderation in temperatures this weekend and early next week

6-Day Forecast

Today

Mostly cloudy, cold, snow showers still likely early in the day, upper 30’s

Tonight

Mostly cloudy, very cold, low 20’s

Saturday

Mostly sunny, not as cold, upper 40’s

Saturday Night

Partly cloudy, cold, but not as bitter as Friday night, upper 20’s

Sunday

Partly sunny, chilly, near 50

Monday

Mostly sunny, warmer, near 60

Tuesday

Partly sunny, still mild, near 60

Wednesday

Mainly sunny, mild, near 60

Discussion

Big cool down continues today and snow showers can linger through the morning hours. Temperatures tonight will drop to frigid levels for this time of year bottoming out near 20 degrees in many locations. Temperatures will, however, moderate this weekend and early next week with highs first approaching 50 degrees on Saturday and Sunday and then 60 by Monday afternoon.

7:00 AM | Warming trend for the weekend

6-Day Forecast

Today

Becoming mostly sunny, warmer, upper 70’s

Tonight

Mostly clear, mild, lows near 60 degrees

Friday

Mostly sunny, warm, near 80

Friday Night

Mostly clear, mild, near 60

Saturday

Mostly sunny, warm, near 80

Sunday

Mostly sunny, warm, near 80

Monday

Partly sunny, not as warm, breezy, low 70’s

Tuesday

Mostly sunny, pleasant, near 70

Discussion

The long-wave trough of low pressure that has been sitting off the west coast in recent days has moved to the east and high pressure has replaced it. An offshore flow of air will develop and temperatures will begin a noticeable warming trend that will last through the weekend.

7:00 AM | Major league cool down with accumulating snow included

6-Day Forecast

Today

Mostly cloudy, much colder, light snow this morning and snow showers this afternoon, highs in the upper 30's

Tonight

Mostly cloudy, periods of snow with a couple of inches possible by morning, very cold, low-to-mid 20’s

Friday

Mostly cloudy, cold, snow showers possible, near 40

Friday Night

Partly cloudy, very cold, low 20’s

Saturday

Partly sunny, cold, mid 40’s

Sunday

Mostly sunny, chilly, near 50

Monday

Partly sunny, warmer, upper 50’s

Tuesday

Mainly sunny, mild, near 60

Discussion

Big cool down begins today as temperatures generally hold in the 30’s and an upper level jet overhead will increase instability giving us light snow this morning and occasional afternoon snow showers. Another disturbance will pass through the region overnight and this will bring periods of snow to the region with a couple inches of accumulation likely by morning. More snow showers can fall on Friday to close out the work week before temperatures moderate some over the weekend.

7:00 AM | Weekend warmup

6-Day Forecast

Today

Early morning clouds then becoming mostly sunny, cool, near 70

Tonight

Mostly clear, mild, lows in the upper 50’s

Thursday

Becoming mostly sunny, warmer, upper 70’s

Thursday Night

Mostly clear, mild, near 60

Mostly sunny, warm, windy, near 80

Saturday

Mostly sunny, warm, windy, near 80

Sunday

Partly sunny, warm, breezy, upper 70’s

Monday

Mostly sunny, warm, upper 70’s

Discussion

The long-wave trough of low pressure that has been sitting off the west coast in recent days will move to the east and high pressure will replace it. An offshore flow of air will develop late this week as this occurs and some of the winds that develop can get quite gusty. Temperatures will begin a noticeable warming trend with the offshore flow that will last through the weekend.

7:00 AM | Another major cool down and snow showers are in the picture also

6-Day Forecast

Today

Partly sunny, cooler, breezy, maybe an afternoon shower, highs near 60

Tonight

Mostly cloudy, chance for a few rain and/or snow showers, colder late, low 30’s

Thursday

Mostly cloudy, much colder, snow showers possible, near 40

Thursday Night

Mostly cloudy, chance for a few snow showers, cold, mid 20’s

Friday

Mostly cloudy, cold, snow showers possible, mid 30’s

Saturday

Partly sunny, cold, low-to-mid 40’s

Sunday

Partly sunny, not as cold, low 50’s

Monday

Mainly sunny, cool, mid 50’s

Discussion

Big changes in temperatures begin today as highs hold to near 60 degrees following yesterday’s readings in the 70’s. An upper level trough of low pressure will bring about this dramatic cool down for the second half of the week as it moves into the region from the west. Snow showers will likely accompany this cold air mass late in the week and some accumulations are possible; especially, in the higher elevations.

3:30 PM | Potential continues for a major storm early next week in the Mid-Atlantic and Northeast; AR1598 is an active sunspot region that has to be monitored as well

Discussion

The potential for a major storm of tropical origin continues for early next week for the Mid-Atlantic and Northeast portions of the country. There are still considerable disagreements amongst the many computer forecast models, but the ECMWF model, perhaps the most reliable in the medium range, continues to point to an incredibly powerful storm for early next week that would be “pulled in” to the Mid-Atlantic or Northeast coast by an approaching deep upper-level trough of low pressure. This type of storm track would bring powerful winds and heavy rains to low-lying Mid-Atlantic and Northeast US locations, and inland snows on the southwest side where cold air rushes towards the central Appalachians. The main player here, Tropical Storm Sandy, continues to intensify over the Caribbean Sea south of Jamaica with current sustained winds at 50 mph. By the way, the main US computer model, the Global Forecast System, continues to predict that this storm will head harmlessly out to sea, but this model has had trouble in the past with coastal storm tracks (ie southeast bias). One final note, there will be a full moon on Sunday, often a factor during historical weather events, and this could contribute to dangerous tides. Stay tuned.

Meanwhile, the sun is quite active just like the tropics in the Atlantic Ocean. A group of sunspots called AR1598 is still not quite directly facing the Earth, but it soon will be. AR1598 has been a very active sunspot region since emerging onto the sun a few days ago. In fact, it has already generated four significant solar flares in that short amount of time and the last one was given the highest strength classification, “X”, but it will not have a direct impact on the Earth’s atmosphere. Stay tuned on this as well as this active region rotates to a position that directly faces the Earth.
