The last several GFS runs have a strong signal ~6 days out for a low pressure to form off the southeast and move northward while intensifying. Revent runs have moved it to the west and intensify the low by a greater degree. This is the 06z run for today, we watch?
The past several HRRR hourglass have been continually weakening the western low and strengthening the eastern one per the same timeframe. The overall system has also been ticcing west
I wonder why that is. Could it be part of a long-term oscillation in weather patterns, increased moisture/southern flow due to climate change, or a mix of both, or something else entirely?
From someone still relatively new to meteorological discussion, what does H5 and H7 mean? Is it the upper level profile at varying heights, or something else
If we get widespread 8-12 we'll need to see models shifting uniformly as we near go time, or they'll have to bust hilariously (which is certainly less common in this day and age)
Already far, far more impressive then Mehnri in my location in BOS. Rain has been moderate all evening but the wind has been picking up throughout the afternoon and is now sustained at 25-30 mph. Almost lost my umbrella
