Morning Observation:

This morning in Huntington at 7:55AM it’s currently 47 degrees and drizzling lightly under mostly cloudy skies. Winds are calm. Relative humidity is 98%, dewpoint 46, barometric pressure 29.33”. We picked up 0.31” of rain overnight. Yesterday’s high was 58, and the overnight low was 46.

Forecast:

The upper level trough of low pressure that brought overnight rains will move east of the region this afternoon bringing showers to a halt later today. High pressure will build into the region tonight and Wednesday for dry weather, but the dry period will be short lived as another upper level trough moves into the northeast Thursday into Friday bringing more rain. Today will be the warmest day of the week and, although high temperatures will be cooler in the coming days, they will remain above normal.

We’ll see cloudy skies with scattered showers today. Highs will be around 50 with west winds 15 to 20 mph gusting up to 30 mph. Chance of rain is 50%. Tonight should be mostly cloudy with a 30% chance of rain showers until midnight. Lows will be in the lower 30s with northwest winds 10 to 15 mph gusting up to 30 mph until midnight.

Wednesday should be partly sunny with highs in the lower 40s and light and variable winds. Wednesday night should be partly cloudy with lows in the lower 30s and southeast winds around 10 mph.

The aforementioned trough of low pressure will move into the region Thursday bringing more rain. Highs will be in the mid 40s with south winds 10 to 15 mph. Chance of rain is 70%. Thursday night rain is likely. Lows will be in the upper 30s. Chance of rain is 70%.

Curious about this warm weather? I did a bit of digging this morning and found that, while El Niño is contributing to the warm conditions over most of the US, a more prominent cause is the Arctic Oscillation (a.k.a the “Polar Vortex”). The AO is the change in air pressure at the North Pole that affects how far south cold air travels from the Arctic. Currently, air pressure over the Arctic is low, or in a strongly “positive” phase, meaning that the cold air remains locked up in the Arctic. Last winter we experienced long periods of “negative” phase which brought lots of cold air into the southern US. Forecasting the weather in these days of climate change is tricky business, especially when combined with the strongest El Niño on record. We’ll just have to wait and see how this winter pans out…

You can read more about how the AO is contributing to our current weather pattern here and here (scientific).
