A rather locked-in jet stream pattern will keep the temperature pattern across the Lower 48 very similar over the next 1 to 2 weeks. An unusually deep trough over the western US, reaching the Baja California peninsula, is being triggered by a large ridge over Alaska. Downstream of that results in a ridge of high pressure over the eastern US, providing above average temperatures. In some of the highest of elevations of the northern mountains in the West, snow has been reported next week, but as a more substantial surface low pressure develops early-next week, a more widespread snow storm could be possible across the intermountain West and northern Plains thanks to the cold air in place. This Thursday, the nation will literally be divided by 2 different air masses. Across the interior Northwest, northern and central Plains, and upper Midwest, it will be quite chilly and definitely fall-like. High…

The model guidance is beginning to hone in onto the potential for tropical development next week. Even the National Hurricane Center has latched onto that idea, highlighting an area of disturbed weather over the western Caribbean Sea with a 30% chance of development within the next 5 days, as of Wednesday afternoon. At this time, there is a region of unsettled weather and an enhancement in showers and thunderstorms near Central America and over the Caribbean Sea. This is associated with the Central American Gyre, which is basically a large, broad area of low pressure. As we look farther out into time to next week, there is the potential for a more discrete area of low pressure to form either over the northwestern Caribbean Sea, southwestern Atlantic Ocean, or the Gulf of Mexico. That all depends on whether the thunderstorms organize around a center and if environmental conditions are conducive…

Another active week of weather is in store for the United States, as multiple weather systems move through while fall-like temperatures intrude parts of the western and central US. This is your 5 Things to Watch This Week. Rosa to Bring Heavy Rain to Southwest: Rosa, now a tropical storm, will make landfall on the northern Baja California Peninsula Monday night, eventually tracking into the Four Corners states midweek. Given the fact that this is a tropical cyclone, there will be copious amounts of moisture associated with the system. Heavy rain and flash flooding will be the main risk from Rosa in the Southwest. According to Head Meteorologist Joshua Feldman, “Initially, the heaviest rain will be focused in the vicinity of the low over the south-central Sonoran desert east of Yuma. The left exit region of the remnant wave’s impressive low-mid level jet will drop the heaviest and most widespread downpours…
