This year you can use the daily max and min temperature data from the NSFGA weather stations to run Maryblyt. Do so by logging in to the NSFGA account on, choose the weather station, select the tab "data" and then choose the view "Monthly Summary". Enter the given values into Maryblyt (except the current date where live data has not yet reached forecast max and min values).
