Spinning up • Snellman Funnel
Either Satellite Loop or Upper Air Pattern Spinning up http://www.meteo.psu.edu/~gadomski/HEMI500/5dayloop.html
Review Temperature and Precipitation for last 3 days Spinning up http://www.meteo.psu.edu/~gadomski/MAXMIN_NA/naloop8.html
Spinning up • Review Regional Surface Weather Map and estimate what the accompanying satellite picture should look like: http://www.meteo.psu.edu/~gadomski/SFCNE/last.html
Spinning up Consider what features are unexpected and ponder what this may mean for the short range forecasts… http://www.meteo.psu.edu/~gadomski/SAT_NE/recentir.html

Tackling the Tues Fcst Challenge • Before reviewing the new guidance- • Follow the flow pattern • Recall where important features are located • Look for surprises on the satellite imagery • Assess the amplitude of the pattern • Estimate where disturbances should go • Review previous guidance – for dM/dT • Then look at the myriad of forecasts
