Narrative:
Flight segment was between ZZZ1 and ZZZ. ATC had cleared us direct to zzzzz intersection. This routing appeared acceptable on the WX radar display. As we were descending through FL190 we experienced a possible lightning strike. After checking aircraft system; we observed the itt parameter on engine #1 was rising and had gone above the green range into the amber. With the thrust lever in flight idle the itt rose into the red range and fluctuated from red to amber. While the first officer was running the engine itt overtemp abnormal procedure; all other engine parameters displayed normal in the green. Engine #1 seemed to be running normally. The abnormal procedure directed us to apply the engine severe damage shutdown procedure. We declared an emergency with ATC; requesting crash fire rescue equipment equipment to be waiting. The flight attendant was notified and briefed. A single engine approach and landing at ZZZ was completed uneventfully. Crash fire rescue equipment inspected engine #1 and aircraft exterior then escorted us to the gate. All passenger deplaned via jetbridge. Postflt inspection revealed lightning had entered at nose cone and exited at right side wingtip and aileron tip; also at left side horizontal stabilizer tip. Dispatch and maintenance control were notified and maintenance logbook entry was completed.

Title: AN EMB-145 EXPERIENCED A LIGHTNING STRIKE AND SUBSEQUENTLY THE #1 ITT TEMP WENT INTO THE RED. THEY DECLARED AN EMERGENCY AND LANDED AT DEST.
Narrative: FLT SEGMENT WAS BTWN ZZZ1 AND ZZZ. ATC HAD CLRED US DIRECT TO ZZZZZ INTXN. THIS ROUTING APPEARED ACCEPTABLE ON THE WX RADAR DISPLAY. AS WE WERE DSNDING THROUGH FL190 WE EXPERIENCED A POSSIBLE LIGHTNING STRIKE. AFTER CHKING ACFT SYS; WE OBSERVED THE ITT PARAMETER ON ENG #1 WAS RISING AND HAD GONE ABOVE THE GREEN RANGE INTO THE AMBER. WITH THE THRUST LEVER IN FLT IDLE THE ITT ROSE INTO THE RED RANGE AND FLUCTUATED FROM RED TO AMBER. WHILE THE FO WAS RUNNING THE ENG ITT OVERTEMP ABNORMAL PROC; ALL OTHER ENG PARAMETERS DISPLAYED NORMAL IN THE GREEN. ENG #1 SEEMED TO BE RUNNING NORMALLY. THE ABNORMAL PROC DIRECTED US TO APPLY THE ENG SEVERE DAMAGE SHUTDOWN PROC. WE DECLARED AN EMER WITH ATC; REQUESTING CFR EQUIP TO BE WAITING. THE FLT ATTENDANT WAS NOTIFIED AND BRIEFED. A SINGLE ENG APCH AND LNDG AT ZZZ WAS COMPLETED UNEVENTFULLY. CFR INSPECTED ENG #1 AND ACFT EXTERIOR THEN ESCORTED US TO THE GATE. ALL PAX DEPLANED VIA JETBRIDGE. POSTFLT INSPECTION REVEALED LIGHTNING HAD ENTERED AT NOSE CONE AND EXITED AT R SIDE WINGTIP AND AILERON TIP; ALSO AT L SIDE HORIZ STABILIZER TIP. DISPATCH AND MAINT CTL WERE NOTIFIED AND MAINT LOGBOOK ENTRY WAS COMPLETED.
