Discussion

A cold front passed through the region last night and the result will be a much cooler day as we close out the work week. In fact, high temperatures today and Saturday will be some 10-15 degrees lower than yesterday’s high which was well up in the 70’s. Another cold front will approach the area Saturday night and early Sunday and it will be accompanied by some shower activity. High pressure builds back into the region for the early part of next week.

Elsewhere, Hurricane Patricia underwent an amazing strengthening yesterday in the eastern Pacific Ocean reaching category 5 status overnight from category 1 levels earlier in the day. The central pressure of this hurricane dropped an incredible 100 millibars in a 24-hour period and maximum sustained winds are now near 200 mph. This hurricane will slam into southwestern Mexico later today or early tonight just to the west of Manzanillo with wind gusts of 185 mph possible. After landfall, the storm will weaken significantly as the center moves inland, but substantial rainfall will continue to fall along its path. By late in the weekend, its remains will affect the western part of the Gulf of Mexico and eastern Texas with significant rainfall and strong winds. After that, rainfall associated with Patricia's remains will likely get caught up in a system that could produce rain here at mid-week.

High pressure has shifted off the east coast and this will open the door for the milder air to ride into the Mid-Atlantic region on southwesterly winds. Temperatures today should rebound nicely to near 70 degrees and then 70+ degrees are likely on Wednesday and Thursday. Another cold front will bring much cooler air back to the region for the end of the week and the beginning of the weekend.

Discussion

Numerous low temperature records this morning in the northeastern US with this early winter preview and some locations downwind of the Great Lakes received significant accumulating snow (e.g., 9 inches at Syracuse, NY). The cold air mass that arrived in the Mid-Atlantic region over the weekend will keep us chilly for another 24 hours or so; however, much milder air will ride in later tomorrow on increasingly strong southwesterly winds and it should stay mild on Wednesday and Thursday. In fact, high temperatures are likely surpass the 70 degree mark in the DC metro region on Wednesday and Thursday. Another cold front will bring much cooler air back to the region at the end of the week.

Discussion

A strong cold front arrives today and it will usher in the coldest air of the season so far for the weekend and the early part of next week. In fact, overnight low temperatures early Sunday morning and again early Monday morning should fall near or below the freezing mark in many suburban locations to the north and west of the big cities along Route I-95. After this early season preview of winter, temperatures should rebound quite nicely by the middle part of next week with increasingly strong southwesterly winds. By late next week, there are signs that the western Gulf of Mexico might become active again and tropical rains could eventually head northeast from there towards the northeastern US.

Discussion

A cool air mass has pushed into the Mid-Atlantic region following the passage of a weak cold front on Tuesday. A much stronger cold front will arrive on Friday – perhaps with an isolated shower or two – and it will usher in a cold air mass for the weekend in the Mid-Atlantic region for this time of year. In fact, for the first time this season, it is possible that low temperatures approach the freezing mark in some northern and western suburban locations late Saturday night/early Sunday morning and late Sunday night/early Monday morning. It turns noticeably milder again by the middle of next week.

A weak cold front will arrive today and it could set off a few mid-day showers, but then clearing is likely late in the day. This front will usher in another cool air mass for the mid-week time period and then a second and stronger cold front will arrive on Friday. That late week cold front will usher in some serious cold air for this time of year for the upcoming weekend in the Mid-Atlantic region and Northeast US. Low temperatures near the freezing mark are quite possible late Saturday night/early Sunday and again late Sunday night/early Monday in some suburban locations of the I-95 big cities.

Discussion

High pressure is in control as we begin a new work week and there should be plenty of sunshine today along with rather comfortable overall conditions. A weak cold front will arrive early tomorrow – perhaps accompanied by a few showers during the morning and mid-day hours – and this frontal passage will be followed by another cool air mass for Wednesday and Thursday. Another cold frontal system will arrive on Friday and it will usher in a downright cold air mass for the upcoming weekend that will be way below normal for this time of year.
