GOES-16 (GOES-East) Mid-level Water Vapor (6.9 µm) images (above) showed the circulations associated with a pair of Hurricane Force low (surface analyses) during the 13-15 February 2020 period. At the limb of the GOES-16 Full Disk view, plots of hourly surface wind revealed gusts in the 70-80 knots range at stations in... Read More
GOES-16 (GOES-East) “Clean” Infrared Window (10.35 µm) images (above) showed a large Mesoscale Convective System (MCS) west of Resistencia (station identifier SARE) in far northern Argentina on 14 February 2020 — this MCS developed southeast of an area of low pressure that was situated well north of a slow-moving cold front...

Gridded NUCAPS fields include a wide range of thermodynamic variables. The plot above shows the 900-mb temperature field. Is it possible to use this data to diagnose a rain/snow transition line? Over southern New England, the relationship between 900-mb temperatures and surface precipitation observations seems robust: snow is restricted to... Read More
GOES-16 (GOES-East) Air Mass RGB images (above) displayed the characteristic pale yellow hues associated with cold arctic air that was moving southward behind a deep area of low pressure centered over Hudson Bay and northern Quebec, Canada on 12 February 2020.A sequence of GOES-16 “Red” Visible (0.64 µm), Near-Infrared “Snow/Ice” (1.61 µm) and Day Snow-Fog RGB images (below)...
