Seasonable in Cambridge; severe weather in the South

In Cambridge, expect mostly clear skies with seasonable temperatures for today and tomorrow as a high pressure system dominates the region. Starting on Sunday, moisture from distance ocean storms may result in clouds and slight precipitation.

Elsewhere, the storm system that spawned 13 tornadoes in Texas this week is now moving over the southeastern U.S., where it is expected to result in severe thunderstorms including hail and isolated tornadoes. Starting next week, several weather offices mean to change the way they warn citizens of severe weather and tornadoes; the new system uses wording intended to frighten people sufficiently to respond to alarms and seek safe shelter before the tornado causes irreparable damage or death.
