An upper level high pressure ridge is going to get stronger bringing dry weather and much warmer temperatures Tuesday through Friday. Some of those high temperatures will be well above normal for this time of the year and therefore we could set some new record highs. A weak cold front slides in Friday just cooling us down a bit. There will be a slight chance of showers with the cooler temperatures behind that front on Saturday.
