CENTER DROP SPLASHED AT 20 KT
Outside/ Inside Temp Spread is 5C
Inside Temp/ Dewpoint Spread is 6C
With an Open Eye Wall. The spreads should begin to increase shortly.
Convection is consolidating and Dmax is about 6 hours from now.
Dmax is the Diurnal Maximum near Sunrise. Whereas Dmin is the Diurnal Minimum near Sunset.
