Impact on min temperature most pronounced. Local mesoscale circulations such as lake or sea breezesalso influence temperature. Limits the diurnal cycle.
Convective downdrafts can be colder than morning min in some cases.
Subtle differences in elevation on the order of tens of meters can have drastic effects, particulary on min temperature. Exposure also important. Good forecasters think for themselves and develop their own strategies and methods for various weather patterns. Use analysis or model forecast temperatures Bring down temperature dry adiabatically to estimate maximum temperature Adjust based on individual temperature bias and local effects When detailed sounding data is available, adjust level from which dry adiabatic lapse rate is estimated based on the vertical temperature profile. Method assumes enough surface heating for a well-mixed boundary layer to form.
