Chilly conditions around here this morning to greet the new work week, but sunshine today should boost afternoon temperatures into the low-to-mid 60’s. High pressure remains in control for the next few days and a warming trend will bring temperatures to well up in the 70’s by Wednesday and Thursday. A cold front then crosses the region on Thursday night and yes, it may be accompanied by some shower activity late Thursday night and/or Friday morning.

A cold front crossed the region early yesterday and it’ll remain on the cool side as we end the work week with high pressure in control. The weekend should start off with sunshine and comfortable temperatures and there will be another cold front crossing the region on Saturday morning. The passage of the cold front will usher in slightly cooler air for Sunday and Monday and temperatures late Sunday night/early Monday should bottom out in the mid-to-upper 30’s.

A cold front crossed the region last night and it’ll be noticeably cooler today with a stiff N-NW wind on the back side of the front. It stays cool on Friday and the weekend begins with comfortable conditions just ahead of the next cold front. That next front will usher in cooler air for Sunday and Monday with high temperatures likely confined to around 60 degrees on both days despite plenty of sunshine.

Last winter was generally warmer-than-normal in the Mid-Atlantic region with below-normal snowfall and 2024 began with a rather strong El Nino event in the tropical Pacific Ocean. However, those warmer-than-normal water temperatures have since flipped to below-normal and this upcoming winter season is quite likely to feature weak La Nina (colder-than-normal) conditions. Typically, La Nina winters feature a more active polar jet stream that helps to transport cold air masses from northwestern Canada into the Northern Plains while, at the same time, much of the southern US often experiences warmer and drier conditions. La Nina winters are somewhat random in the Mid-Atlantic region with respect to temperatures and precipitation with some years featuring more snow than normal and others less.

Today will be another warm day in the DC metro region featuring plenty of sunshine and an increasing S-SW wind. A cold front crosses the region later tonight and it’ll become noticeably cooler on Thursday with a northwesterly breeze on the back side of the front. It stays cool on Friday and the weekend begins with comfortable conditions ahead of the next cold front. That front will pass through on Saturday and usher in cooler air for Sunday and Monday with high temperatures likely confined to near 60 degrees on both days despite plenty of sunshine.

Today will be the warmest day of the week and possibly a record breaker in some spots with afternoon highs in the lower 80’s. It stays warm on Wednesday ahead of the next cold front, but will turn breezy and noticeably cooler for Thursday and Friday. The weekend starts off comfortably cool on Saturday and then becomes even cooler for Sunday as a second cold front will cross the region. In terms of rainfall, the chances are quite small for the next few days with only the chance for an isolated shower during the weekend as the next cold front arrives.

Since the middle of last week, two separate tropical systems attained tropical storm status adding to the year’s total number of named storms to 15 in the Atlantic Basin. Neither one of these most recent tropical storms, Nadine and Oscar, are a threat to the US mainland as the first one has already dissipated and the second is destined to push out over the open waters of the western Atlantic Ocean. There are signs, however, that tropical activity in the Atlantic Basin may be very well get boosted again as we push into the first half of November.

The main theme of the weather this week will be “dry, dry and more dry” with little chance of rainfall around here as has been the case all month long. High pressure remains in control as we begin the new work week and the next system of note will be a cold front that passes through on Wednesday night…without any rainfall. Temperatures will climb well up in the 70’s today and to near 80 degrees tomorrow afternoon, and then cool down later in the week following the mid-week frontal passage.

Very strong high pressure throughout all levels of the atmosphere remains parked over southern Canada and it will keep us dry and comfortable for the next several days along with plenty of sunshine. Temperatures have been running at well below-normal levels for the past few days, but will begin a climb today featuring afternoon highs well up in the 60’s, and then 70+ degrees is possible on both weekend days. The dry weather pattern continues in a month that has featured very little, if any, rainfall in the DC-to-Philly-to-NYC corridor.

October can be a dry month in the Northeast US with the usual overall cooling down of the atmosphere, but this one has been pretty ridiculous. While tropical moisture has inundated the Tennessee Valley/Appalachians and Southeast US during the past couple of weeks, nary a drop has fallen in the DC-to-Philly-to-NYC corridor and there is not much reason for hope in the next week or so. Perhaps...just perhaps...there may be some decent rainfall here around the end of the month as a strong cold frontal system heads this way from central Canada.
