Relative Short-Range Forecast Impact from Aircraft, Profiler, Radiosonde, VAD, GPS-PW, METAR, and Mesonet Observations via the RUC Hourly Assimilation Cycle Abstract An assessment is presented on the relative forecast impact on the performance of a numerical weather prediction model from eight different observation data types: aircraft, profiler, radioson...

From knowledgeable scientists we’ve talked to, RAOBs have the second largest increase in error for upper air metrics when removed, behind aircraft data.

On average, losing RAOBs will decrease mesoscale NWP forecast skill.

We have some big fluffy dendrites falling with surface temperatures in the single digits thanks to the shallow surface inversion. Very interesting setup with today’s event!

Great article discussing the state of ENSO and why the atmosphere is behaving more La Niña-like this season than the Niño3.4 index might suggest!

Highly recommend spending some time somewhere that doesn’t have cell service!
